RevIVAL oF Fruit TREES prematurely ceasing to bear fruit, or prema- turely decaying, by Guo. B. Woop, M. D. Communicated to the American Philosophical Society, January 6, 1871. Ys y > It is well known that most fruit trees, especially the peach and apple trees, in sites where they have been long cultivated, often cease to bear fruit, and even perish, long before their natural period. Thus the peach, which has a normal life of 50 or 60 years, or longer, and grows under fa- vourable circumstances to the size of a considerable tree, generally, in this part of the United States, ceases to bear fruit after two or three years of productiveness, and soon after begins to decay, seldom living beyond 15 or 20 years. The apple tree also, long before it has attained its normal length of life, often ceases to yield fruit, cither for a time or permanently, without apparent cause; and trees, planted on the site of an old orchard which has been removed, not unfrequently refuse to bear at all, or at least to a profitable extent. Tt is obviously of great importance to discover the cause or causes of such failures, and, if possible, to apply a remedy or preventive. Unless I greatly deceive myself, I have succeeded in showing that the evil gen- erally has its source in a deficiency of the salts of potassa in the soil, and may be corrected by supplying that deficiency. The alkali potassa, in combination generally with one or another of the vegetable acids, is an essential ingredient in all plants, excepting the sea plants, in which its place is supplied by soda. In living vegeta- bles it is contained dissolved in the juice, and is consequently most abun- dant in the most succulent parts; and, when the plants are burned, the al- kaliis left behind in the ashes, of which it constitutes an exceedingly vari- able proportion, according to the peculiar plant or part of the plant burned. Thus, while the ashes of oak wood contain only about 3 parts in 1000, those of the common poke, the growing wheat stalk, and the potato stems, contain 48 or 50 parts or more. The greater portion by far of the alkali is in the state of carbonate, with a little in the caustic state, and being, inthese conditions, very soluble in water, is extracted by lixiviation Wood.] 4 [Jan. 6, with water, and obtained by evaporating the ley. A muchsmaller portion is in the form of silicate, whichis left behind in the ashes after lixiviation, and gives to the soap-boilers’ ashes almost all if not quite all their value asamanure. It is, however, only the fresh-burned ashes, not yet sub- initted to lixiviation, and consequently still containing the potash in its soluble state, that is applicable to the purpose of supplying the alkali to fruit trees in the mode in which I employ it. When plants are no longer supplied with the requisite amount. of pot- ash, they cease to grow, and at length generally perish. In the case of the succulent fruit trees, as the alkali is required in the largest propor- tion in the fruit, this is the first to suffer; then the leaves gradually fail; | and at length the whole tree dies, limb after limb. How I came to discover this source of premature failure of fruit trees, and to supply the deficiency by means of the soluble potash contained in fresh ashes, J explained, so far as the peach tree is concerned, in a com- munication made last year to the Scciety, which was published in the Proceedings. In that communication I stated that, believing with most others that the peach tree perishes prematurely, in consequence of being at- tacked near the root by a species of worm, I employed as a remedy against this parasite, after scraping as far as possible the worm out of the root with a knife, fresh ashes in an excavation about the stem of the plant; supposing that, by their caustic power, they might destroy any re- mains of the insect or its eggs. This method was not original with my- I self; as I had seen it practiced in my youth very effectually in keeping a | peach orchard in bearing for several years. The peach trees on which I tried the experiment had long ceased to bear fruit, and were in the last stage of decay ; in several instances one or more branches being absolutely dead, and the stem being covered with lichens, as is apt to happen with dying trees. | This was done in the Autumn; the earth having been removed around i the stem of each tree to the depth of four or five inches, so as to lay bare the upper surface of the main roots, and the excavation filled with fresh | | ashes. Next Spring a marvellous change was experienced by the trees. \ | They had recovered more than the vigor of their early life, and bore fruit in an abundance which I had rarely, if ever, witnessed. I could not conceive that such a result should proceed so rapidly, from the destruction of a few worms. Besides, some of the trees had no worms | that could be observed; and yet they had been as far gone, and were as much revived as the others. I was, therefore, driven to the conclusion, that the ashes had not acted by destroying the worm, but by furnishing to the trees a material neces- | sary to their existence, and from the want of which they were perishing. This could only be the soluble potash contained in the ashes, which being dissolved by the rain, was carried in solution along the roots to the mi- nute rootlets where it was needed. One important inference, which may be here incidentally mentioned, is 1871. ] v L Wood. that the peach trees were not dying from the worms, but that these at- tacked them because they were dying from other causes; and it is proba- bly true, as a general rule, that plants in perfect health are in a condition to protect themselves against destructive parasites, probably because the salts of potash in their vessels are repulsive or even destructive to the parasites, which destroy the plant in the absence of this defense. I am not certain even that the curculio may not attack certain fruits, the plum for example, in consequence of deficiency of the alkali in its juice. At first my experiments were confined to the peach tree; but it may be remembered that I said in my communication to the Society that the principle was applicable as well to other fruit trees, especially the apple, which often refuses to bear, apparently capriciously, but probably from the same deficiency of potash in the soil. Last year I had the opportunity of testing the correctness of this sup- position. I happened to have two apple orchards; one of them old, per- haps 60 years or more, the other comparatively young, having been planted, 15 or 20 years since, upon a piece of ground which had previously been the site of an apple orchard for I presume nearly a century. Both of these orchards might be considered as nearly or quite barren; the old orchard not having borne fruit of any account for 5 or 6 years; and the young one having never borne at all. In the Autumn of 1869, I tried with these trees the same experi- ments as in the Autumn before I had tried with the peach trees. The earth was dug from around their stems to the depth of about 5 inches, and the excavation filled, in each case, with about half a bushel of fresh ashes. As regards the old orchard, a part was allowed to remain without treatment, soasto secure the effect of contrast. Inthe following Spring and Summer (1870), my expectations were fully realized. Early in the sea- son a striking difference was observed between the trees not treated with ashes and those which had been so treated. A dividing line could be observed between the two sections of the orchard; the trees which had been ashed being forward both in leaf and blossom, while the others had made little progress; and the same contrast was presented in the fruit; the trees left to themselves continuing barren, while the ashed trees were loaded with apples. The young orchard, which had never borne fruit of any account, was also made for the first time very productive. A similar experiment I tried on several fruit trees of different kinds in my garden in town. Though the ashes were applied in Spring instead of of Autumn, the trees in the growing season gave evidence of a similar result. The trees were richly covered with blossoms, which were just becoming exchanged for young fruit, when the famous hail storm which proved so destructive in this city last Summer, put an end to the experi- ment by stripping the trees of blossom and fruit, and to a great extent even of their leaves. Among the trees was a very old Newtown pippen tree, probably of not Wood.] 6 Jan, 6, less than three-quarters of a century, which had for years ceased to bear, or at best only now and then brought forth a smail knotty fruit unfit for usc. The tree had been dying branch by branch every year, until re- duced almost to the original stem, with a few branches above. This tree appeared in the warm season to have renewed its youth. It was richly loaded with flowers and fruit, and gave hopes of an abundant product in the Autumn. It suffered, however, like the others from the storm ; very few of the blossoms or young fruit remaining still attached. One of these went on to full size; and the handsome Newtown pippen which I now exhibit to the members as the sole relict of the storm, shows what the product might have been had not the hail interfered. I consider that the efficiency of potassa in the revival of fruit trees has been satisfactorily demonstrated by the foregoing experiments, at least in relation to the peach and apple trees, and I may add also the pear and quince, several of which were treated in the same way and with similar results. As to the securing of the plum and other fruits against the curculio, J think it highly probable that this also may be done by ashes, on the principle already stated, but I can adduce no proof of the fact; for, in the only instance in which ashes were applied to a plum, though the tree showed its effects by a copious growth of leaves and flowers, and even of young fruit; yet the destruction of these by the hail storm prevented the completion of the experiment ; and for the determination of this point, which is an important one, we shall have to wait another year. But, important as I consider the discovery of the reviving power of potassa in the case of failing fruit trees, I attach much greater value to its influence in another direction, which has suggested itself in the prosecution of the foregoing experiments. It is an unfortunate fact, with which the farmers of my own country neighbourhood are unhap- pily but too familiar, that certain cereal crops, especially that of wheat, have for some years failed to be remunerative. Where wheat formerly yielded 20 bushels or more to the acre, it can now seldom be made to produce more than 12 or 15 bushels. Tn examining into the relative proportion of potassa contained in the ashes of different plants, I was surprised to find that, while the ashes of the common fire wood, as the oak, maple, &c., contain from about 2 to 4 parts in 1000, the wheat stalk yields 47 parts. Now, while this fact shows the extraordinary demand of growing wheat for potassa, it sug- gests also that the failure of this crop of late may be owing to the same deficiency of the salts of potassa in the soil which has caused the premature destruction of the peach; and, though the manure employed in the culti- vation of wheat contains potassa, yet it does not yield as much of this al- kali as the plant requires for its greatest productiveness ; few of the vegetables that unite in the constitution of manure containing so large a proportion as wheat. To meet this demand of wheat, I propose to employ unleached ashes in the cultivation of this cereal. Leached ashes, though * containing but a small proportion of potassa, and that chiefly in the form ~ 1871 ] ( [ Wood. of insoluble silicate, have nevertheless been found one of the best fertilizers for wheat; and the unleached, if properly applied, would probably pro- ducea much greater effect. This is as yet conjectural; but I have in- stituted an experiment which I hope may determine the point. In the early Autumn I caused an acre of ground to be prepared for a wheat crop. It was divided into three parts, one of which was to be treated with fresh ashes exclusively, another with ashes and swamp muck, and the third with muck alone. The part treated with fresh ashes ex- clusively was first ploughed, and then sown with wheat and ashes, and finally. harrowed; the ashes being applied to the surface, so that its potassa when dissolved by the rain should be in immediate contact with the germinating seed; instead of being ploughed in, as ordinary leached ashes are. The second part, after being covered with the muck, was ploughed; and the wheat and ashes were applied as before. The third part was simply treated with muck, then ploughed and sown with wheat. The result of this experiment cannot be determined until the time of the wheat harvest next Summer; but, thus far, it is decidedly in favor of the ashes; the two-thirds which were treated with this material being obviously better grown than the part treated with muck alone. A glance of the eye is sufficient to show a decided line of demarcation, the ashed part being greener and further advanced than the remainder. T have little doubt that the same remarks are equally applicable to the common potato. This is now a much less certain, and on the whole much less productive crop than formerly. I find that the potato stalks contain 55 parts of potassa in 1000 of ashes; so that the plant requires consider- ably more potassa than wheat. If, therefore, fresh ashes are to be a rem- edy for the failure of the wheat crop, they are likely to be even more so for the potato. The verification of this supposition experimentally I have reserved for the next year, when, if living, I propose to try an experiment on a large scale. An objection to all the foregoing facts, in a practical bearing, is the question whence the ashes are to be obtained for carrying the proposition into effect on a large scale, and whether enough can be obtained for the purpose. An obvious answer to this objection is that, should ashes fail in any neighbourhood, recourse can be had to the crude potash of the shops derived from the lixiviation of the ashes of forests cleared in the course of cultivation, and, when these forests shall have all been destroyed, we may resort to the minerals containing pota as to the felspar in granite rocks, which contains a large proportion of that alkali. But for a long time yet to come, and indefinitely as regards fruit trees, ashes can be obtained from the resources of the farm itself. If all the falling leaves of the woods and swamps, all the dead and dying branches or stems of trees, and all the weeds, trimmings of trees, and other rub- bish of a farm be collected and burnt, enough ashes could probably be obtained annually, for an indefinite length of time, to keep all the fruit trees in full bearing.

(Read before the American Philosophical Society, Jan. 20, 1871.) When the maximum load of the same engine on any two different incli- nations has been determined by experiment, the data thus furnished will suffice to calculate the load on any other inclination, the load on a level, the angle of friction at which a train will descend by gravity, the tractive power per ton of load required on a level, and the number of pounds adhesion for each ton of load. ; Let R = resistance of the train on a level, which is equal to the power of the engine. W = gross weight of train on a level. W! — Weight of train on grade a. W? = Weight of train on grade b. It is proper to assume that the power required to move a train and the resistance, which is equal to it, will be in proportion to the gross weight. The force of gravity on any inclination is in proportion to the height of the plane divided by its length, or as the rise per mile divided by 5280.

By substituting the values of W W' W2a and b, the value of R on the power exerted by the engine is obtained. By dividing this power in pounds by the gross load on a level, the trac- tile power per ton is determined. As the power of an engine is always sufficient to slip the wheels ona dry rail, the adhesion is equal to the actual power exerted in moving the train and divided by the weight on drives, gives the proportion between adhesion and weight. ‘rhe angle of friction can be found when the tractive power per ton of of 2000 Ibs. on a level (T) has been determined, by the equation. T X 5280 2000. It has been customary for engineers to consider the angle of friction as 16 to 18 feet per mile, the tractive power per ton on a level 8 pounds, and the adhesion one-eighth the weight upon the drives; but to obtain reliable data from the actual operation of roads running full trains, a letter was addressed to A.

If the gross load of a train on a grade of 30 feet be 541 tons, the engine and tender being 63 tons, the cars and contents will weigh 478 tons, or if 18,000 Ibs. be allowed for each car and 22,000 lbs. for load, the number of cars will be 27 and the net load 297 tons, weight of cars 243 tons, If the return cars shall be only one-fourth loaded, which is probably a full proportion for the Shenadoah Valley extension, the gross weight of the trains would be 380 tons. The inclination that would employ the full power of the engine in haul- ing 880 tons, would be 58 feet. The inclination that would employ the full power of an assistant engine in hauling a gross load of 380 tons, would be 130 feet, but allowance must be made for the weight of the assistant engine. ’ The following description of Indian sculpture on the banks of the Monongahela River, by Jos. D. Reid, was received through Prof. Cope, accompanied by a drawing of the same. SKETCH AND Description or A CARvED Rock on the bank of the Mo- nongahela River, Pa., by Josepu D. Rein. (Read before the American Phiiosophical Society, Jan. 20, 1871.) The engraving represents the face of a large rock lying on the east bluff of the Monongahela River, in Fayette County, Pennsylvania, oppo- site the village of Millsborough and the mouth of Ten Mile Creek, Reid.] 12 [Jan, 20 1871. Originally there were three rocks, but after the settlement of the coun- try, two of them were broken up and used in building a mill dam. At that time no one valued or took any interest in them, so no record was kept other than the fact that they were larger, and the figures more nu- merous than on the one remaining. This is in its original position, partly buried in the earth and so worn by the elements that the figures have be- come indistinct, and some perhaps entirely obliterated. The Indians that inhabited this part of the conntry at the time of its settlement by the whites, had no legend connected with the rock, nor had they used it for any purpose. The river bank at this point and for a mile above and below is nearly a perpendicular bluff, three hundred feet high, which is broken by a single ravine, and up this by a narrow winding path, apparently made by the same people that carved the figures on the rock, it may be reached directly from the river. A carriage road that leaves the river opposite Fredericktown, and winds around behind the bluff, passes within a few hundred yards of it. The rock is sandstone, of the same formation as that overlying the coal bed below; the surface is nearly flat, of an area of twenty by twenty-four feet, with a depression diagonally across, in a line with the three cups or hollows, the largest of which is one foot in diameter, the middle one six inches, and the other three inches, and about the same in depth. The de- pression or gutter and cups, are discolored, apparently by the blood of the victims that the inhabitants offered as sacrifices to their deity. The south end of the rock is three feet above the ground, with a hog- like figure carved upon it. The foot and hand prints are deeper and more perfect than the other figures, and in no way can I better describe them than they present the appearance of having been made by pressing the naked fect and hands upon soft clay, so perfect are some of the im- pressions. This is particularly the case with one foot-print, with a large toe on each side of the foot, and a hand-print with a thumb on both sides. The largest impressions of feet measure fourteen inches in length, eight inches across the toes, and four inches across the heel, the other foot-prints vary in size from that of a full grown man to a child five years of age; the foot-prints of syuirrels are numerous and cross the rock in every direction, not all that were on the rock being represented in the en- grvaving. A single track of an animal with claws, and one intended to re- present a buffalo track, but too smal] and no division of hoof, are also on the rock. The bird tracks are quite distinct:and six inches in length; the three links have apparently been made recently. The other figures are outlines, and whether made as a pastime by some Indian artist or as the hieroglyphic history of an Indian race, I leave others to determine. Two miles down the river from the rock is the site of an old Indian town and grave-yard, which covers an area of fifteen or twenty acres. There may be found pieces of sun dried pottery made of clay and minute fragments of muscle shells, pipes of the same material, and some of soap stone, axes of red 2jasper as hard as steel, arrow heads of flint, and cireu- lar flat sandstones, two of six inches in diameter and froin one-fourth of 13 an inch to one inch in thickness, some of them with a hole in the centre and with a worn appearance of the edge. The graves are covered with flat stones taken from the cliff above the town; they were placed about two feet below the surface, and being out of reach of the plow, the graves are seldom disturbed; one opened a few years since, exposed the skeleton of a female in a sitting position with a child in her arms, the skull of the child stuck to the stone, and when ex- posed to the air for a few minutes a slight puff of wind carried it away in a little cloud of dust. The skeletons are found in a sitting position facing the east and after being exposed a short time fall to dust. Noth- ing besides pieces of charcoal have been found in the graves with the bones.

Donations for the Library were received from the Italian Committee of Geology, the Academia dei Lincei at Rome, the Berlin Academy, the London Astronomical Society, the Essex Institute, the Boston Natural History Society, the American Journal of Science, the Franklin Institute, Penn Monthly, Pennsylvania Institution for the Blind, American Journal of Pharmacy, and London Nature, lo The death of George Ticknor, of Boston, a member of the Society, Jan. 26th, aged 80 years, was announced by the Se- cretary. On motion, Dr. H. Hartshorne was appointed to prepare an obituary notice of the late Dr. Rhoads. On motion, Prof. Kendall was appointed to prepare an obit- uary notice of the late Prof. Chauvenet: Mr. Cope reported that Mr. McNeil was prosecuting his re- searches in Panama, and had sent home fossils, showing among other things, that the back bone or water shed of the Isthmus was an ancient coral reef, many of the corals being in an excellently well preserved condition. THE PORT KENNEDY BONE CAVERN. Prof. Cope announced the discovery of a bone cave by Mr. Charles M. Wheatley, in the Calciferous limestone, at a point about 25 miles N. W. of Philadelphia. There had been obtained numerous remains of plants, and insects, with about thirty species of vertebrata. These consisted of Reptiles, Birds and Mammals. The first were ser- pents, and tortoises of several species, mostly harmless. The birds in- cluded a turkey and snipe. The manimalian remains were most numer- ous, embracing various forms. There were Rodentia, of American types, as IHesperomys, Fiber, ete. ; also Sciurus, Lepus, ete. There were Ruminants, several tapirs, and a small horse. Two carni- voxes of large size, one a cat, the other a bear, Ursus pristinus of Leidy, of a remarkable type, and entirely distinct from the cave bear, or living species of Europe and America. Remains of several Sloths were discoy- ered, which were mostly of gigantic size. These were referable to at least three species, one Megalonyx wheatleyt was new, and two Mylodons, one of them probably also new to science. With them occurred the teeth and tusks of the Z’rilophodon ohioticus (Mastodon). This animal had pro- bably fallen in, as the cave was rather a fissure at the point examined. The bones were not gnawed. ‘The fissure was 40 feet deep, 15 feet in width, and of unknown length. Above the cave deposit, it was filled with wash from neighboring hills of Triassic age. 16 Mr. Lesley desired to place on record the recent exposure of a bed of solid brown hematite iron ore, at the upper limit of No. II, Lower Silu- rian Limestone Formation, in Leathercracker Cove, Morrison’s Cove, Middle Pennsylvania, of very unusual size. The bed is nearly vertical and 72 feet thick, where cut across by a water drift. No such deposit has been before discovered at this horizon, in a situation favorable for exact measurement. Pending nominations 669, 670 were read, and the reading of the list of members was postponed, and the Society was adjourned. Stated Meeting, February 17, 1871. Present, ten members. Mr. FRALEY, Vice President, in the Chair. Mr. Carey accepted by letter, the appointment to prepare an obituary notice of Mr. Colwell. Letters of acknowledgment were received from the New York, New Jersey, and Georgia Historical Societies (85); Cincinnati Observatory (85) ; Smithsonian Institution (84 and RIV. 2), and Reichenbach N. H. Society (78, 79, 80). Donations for the Library were received from the Royal Academy and Observatory at Turin, Levant Herald at Con- stantinople, London Nature, Philadelphia Journal of Phar- macy, Medical News, McCalla & Stavely, the Librarian of Congress, and the Wisconsin State Historical Society. No. 85 of the Proceedings, just published, was laid on the table. The death of John F. James, a member of the Society, at Philadelphia, Feb’y 5, was announced by the Secretary. Mr. Lesley asked for information respecting the alleged dis- covery of a hewn cave and erypt with hieroglyphics, skele- tons, vases, &c., lately made by a railroad engineering party Feb. 17, 1871.] l T { Emerson. in Iowa; and connected it with Baron Burck’s account of the traditions he found among the Aztecs, of the migration of that race or tribe from the Northeast or Upper Mississippi and Missouri country. Mr. Coxe described a locality at Baker’s Run, on the West Branch of the Susquehanna, where the great freshets of 1868 uncovered ancient hearths and numerous large vases, all of which were soon broken and scattered by the curious. The minutes of the last meeting of the Board of officers were read. Dr. Emerson introduced the subject of Lunar Influence, or e ’ supposed influence, upon the conditions of wet or dry weather. On Lunar INFLUENCE upon the Conditions of Wet or Dry Weather, by Dr. Emerson. (Read before the American Philosophical Soctety, February 17, 1871.) That the moon exerts such an influence, he said, is a very old opinion, widely spread at the present day, and even maintained by many distin- guished philosophers. A great deal of attention has been devoted to tabulating atmospheric observations in relation to the conditions of the weather at the quarterly changes of the moon. The results of such labo- rious investigations have, however, not been found to agree, some reports seeming to favor the existence of lunar influence in producing wet and dry weather, and others, to show that no such influences are exerted by the moon upon the hygrometric conditions of our atmosphere. Among the many who have engaged in investigating this subject I will only re- fer to the celebrated Italian philosopher Toaldo, whose observations were extended through a period of forty-five years, and to Pilgram, whose ob- servations were extended through a period of fifty-two years. For some reason which I shall not attempt to explain or examine, the conclusions of these indefatigable observers and inquirers were the very opposite of each other. The circumstance which has perhaps contributed most to strengthen the belief in lunar inflnmence upon the weather, is the well known agency exerted by the satelite upon the ocean and atmosphere, in the production of tides and barometrical fluctuations. Both of these phenomena are at- tributable to the force of gravitation, acting between the earth and moon, and giving rise to ocean and atmospheric waves. The atmosphere surrounding our earth consists : first, of a mixture of permanently elastic gases; and secondly, of a changeable atmosphere of watery vapor, depending for its suspension entirely upon heat. This A. P. §S.—VOL. XII—C Emerson. | 18 [Feb. 17, 1871. theory of an independent atmosphere of vapor owing its suspension to heat alone, was established by Dalton, and is as incontestible as the theory of gravitation established by Newton. When watery vapor suspended in the air loses the amount of heat ne- cessary for its suspension, or, in other words, when the temperature is reduced to the ‘‘Dew-point,’’ vapor is immediately condensed into mist, dew, clouds and rain. Now there is good reasun to believe that the moon exerts no appreciable influence, directly or indirectly, upon the tempera- ture of our atmosphere. Some who have attempted to investigate this point by using reflectors and very delicate thermometers, have been led to the absurd conclusion that the moon’s rays emitted cold. The marked depression observed in the thermometers exposed to the lunar rays, was in no wise produced by these, but by radiation of heat from the instruments into a clear sky. In many parts of the surface of our globe, extensive regions exist in which it seldom or never rains, as in Lower Egypt. But in such places the atmosphere is very dry, and no local causes exist, such as mountains or hills, to interfere with the regular currents of the atmosphere and. favor the mixture of strata of different temperatures. Consequently, rain rarely falls. In other regions, in the Tropics, for example, there are extensive spaces in mid-ocean embracing many thousands of square miles, where the tem- peratures of the sea and atmosphere remain constantly within one or two: degrees of each other, with the atmosphere of vapor close upon the “Dew-point.’’? Here, if anywhere, the moon might be expected to pro- duce changes in the hygrometric conditions of the atmosphere. But for months continued, there is no rain or other proof of lunar influence upon the weather. It is only in the extra-tropical latitudes where many other active agencies exist to disturb the equilibrium of atmospheric tempera- ture, that the advocates of lunar influence assume to find evidence in fa- vor of their views. The power exercised by the moon upon bodies of water and permanent elastic gases on the surface of our planet, is solely derived from the law of gravitation, which exercises no influence, direct or indirect, in suspend- ing or condensing vaper, or controlling the conditions of weather as to wet or dry. These conditions are brought about solely through changes of temperature, during the operations of which the moon remains a silent spectator, taking no active part, so far as the condensation of vapor is eoncerned. Pending nominations 669, 670 were read. On motion of Mr. Winsor, the Library Committee were in- structed to report upon the subject of completing and pub- lishing the Catalogue of the Society’s books and pamphlets. And the meeting was adjourned. ( Dee. 2, 1870.] 19 i Pepper. A CASE OF UNIVERSAL HYPEROSTOSIS, ASSOCIATED WITH OSTEO- POROSIS, WITH A DESCRIPTION OF THE SPECIMENS, by J. Ewine Mears, M. D., W. W. Kenn, M. D., Harrison ALLEN, M. D., and WiLt1AM Perper, M. D. (Read before the American Philosophieal Society, Dec. 2, 1879.) The undersigned, to whom were referred the above specimens, presented by a friend to Dr. J. Ewing Mears, have carefully examined them, and have prepared the following Report :— In the investigation of the subject, we have prepared as full a history of the case as could be obtained, a detailed account of the general ana- tomical characters of the disease, and of the peculiarities of each individ- ual bone, as well as of the microscopic appearances, have consulted the works and periodicals in various languages accessible in this city, and have examined all the specimens contained in the Museums of the Col- lege of Physicians, Academy of Natural Sciences, University of Pennsyl- vania, Jefferson Medical College, and also the hospital and private collec- tions in the city. We have nowhere found specimens of this disease, or descriptions of such, at all equalling in extent and severity these here described. The only similar case, though far less in degree and extent (skeleton imperfect), is found in Virchow’s Archives, Vol. 43, 1868, p. 470, plate No. 12, although we have met with specimens and descriptions of skulls and bones which afford evidences of a limited development of the same disease. Of the pathology of the disease, as well as of the anatomical appear- ances (116), we have found the best descriptions in Lobstein, Traité @anatomie pathologique, Tom.

HISTORY OF THE CASE. Fully recognizing the importance the history of the case has in the dis- cussion of the Etiology and Pathology of the disease, we regret our inabil- ity to add any information to the statement given at the time of the presentation of the specimens, which is as follows :— A. M. aet, 14, native of England—occupation farm boy—came from England to this country when very young—father died in November, 1862, of Phthisis, aged 57—mother died in 1867, cause of death not as- certained—has one brother and one sister, both young and healthy. In September, 1866, while engaged at work on the farm, noticed swelling Pepper.] 20 [ Dec; 2, beginning in the face, and also, that in stooping, face felt puckered and wrinkled, while the effort to regain the erect position gave intense pain along the entire spinal column. Subsequently the fore-arms became sore and swollen, was placed under treatment, which was of such decided benefit that he thought himself entirely well, and in March, 1867, re- sumed his farm duties ; about two months later the symptoms returned in an aggravated degree, the feet and then, in succession, the legs and thighs becoming enlarged and very painful ; under the influence of con- stant bandaging the swelling diminished ; his appetite became impaired, and he died from exhaustion Feb’y 8th, 1868. The treatment adopted was mostly of a tonic character. DESCRIPTION OF THE SPECIMEN (See Plates I. and II.) I. WHAT BONES ARE WANTING. We have the entire skeleton except the following bones : Vertebra—dth and 7th cervical. 1st and 10th dorsal. 2d lumbar. 2d and 4th sacral. all the coceygeal. Sternum, gladiolus and ensiform. Hyoid bone. Right Patella. Hands, all wanting g save the right seaphoid. Feet, all wanting save left calcis. Five metacarpal and metatarsal bones and eight phalanges are pre- served, but, except the two metatarsals of the great toe, they can scarcely be designated, they are so greatly deformed. II. THEIR CONDITION. Unfortunately, by the prolonged boiling to which they were sub- jected before coming into our possession, the bones have lost proba- bly all their animal matter, and are now almost as friable as if they had been burned. By removing the marrow, also, this has rendered the pathology of the disease much less clear and the microscopic examin- ation much less valuable than it would otherwise have been. Moreover, it has removed probably all the gelatine, so that the chemical examina- tion and the specific gravity would be worthless. Even the weights are, by reason of this misfortune, only of slight value. All the epiphyses too, except the coracoid process of the scapula, are separated from the shafts or bodies, and in some bones even integral parts are separated, e. g. the sa- crum is divided into its component vertebre and the innominate bone into two pieces. Many of the epiphyses are preserved, as will be indi- cated in describing each bone. The epiphyses have attached to them in many places the dried gelatinous articular cartilages of a transparent 9] 1870. ] a [Pepper brown color, and when an epiphysis has been incompletely essified, the cartilaginous portion presents itself as a similar dried gelatinous mass. The ends of the shafts of the long bones are very ragged also, the can- cellated substance being exposed and more or less broken. III. WEIGHTS AND MEASUREMENTS. In order to have some relative standard of weight, we have also weighed the bones of a girl of about seventeen. But, it must be observed, that all these but the scapula (which wanted the acromion epi- physis) were weighed with all the epiphyses. These healthy bones were rather slender, but were also longer than the diseased bones (the diseased and healthy femurs being 14} and 16 inches respectively, ex- cluding the lower epiphyses).

The bones which have suffered the most are the clavicle, humerus, ra- dius, ulna, femur, tibia, fibula, metacarpals, or-tarsals and phalanges of both hand and foot. These are diseased in almost the entire length of their shafts. The radius and ulna have suffered rather more than any of the other bones just named. All the other bones of the trunk have suf- fered to some extent, those of the skull but very little or not at all. Comparing the upper and the lower extremities, there is no appreciable difference in the violence of the disease. Comparing the two sides externally, not only is there no difference in the extent and character of the disease, but there is the most remarkable symmetry of the corresponding, diseased bones, which may be traced even to details. (Figs. 9 and 10.) The disease begins and ends on both sides at corresponding points, it changes in character from simple porosity to the growth of osteophytes at corresponding points; if on one side the posterior part of the bone is most diseased, the same is true of the other side; if the osteophyte growth is continuous or interrupted on one bone (fibula Fig. 18) it is so on the opposite one; if one is unusually diseased at a tendinous or aponeurotic insertion, so is its mate ; if a groove or a variation in color exist on the one side, the same will be found on the other side; even of single marked spicule of bone the same may be said; so that a description of one side will answer for both, minute differences being noted as they occur. The main violence of the disease is expended on the shafts of the long bones. The epiphyses, of which the most important remain, e. g. those of the femur, tibia, humerus, &c., show we may almost say nodisease. The lower epiphysis of the femur is slightly porous in the usually compact layer of the articular surface, but so fine is the porosity and so slight the disease that it would not be observed save on a most careful examination. 1870, ] — [Pepper. ‘The other epiphyses show occasionally still slighter disease. Indeed it is a question whether this be not the result of the prolonged boiling. The bones of the trunk are but little affected except the sternum, which must have suffered severely, the manubrium being very porous and much thickened. The bones of the head are scarcely at all affected. The point of greatest development of the disease varies with its char- acter. 1°. The thickening is most developed in the middle of the shafts, and here generally the sclerosis is furthest advanced. (Figs. 3, 4, 5, 21.) 20, The porosity is not noticeably greater in any particular parts of the shafts, but seems externally to be equally diffused. 3°. The osteophytes follow a marked law in their development. They are most developed where the muscles, aponeuroses, fasciae, &c., are attached, ¢. g. the linea aspera, interosseus ridges of the tibia and fibula, radius and ulna, the insertion of the deltoid, biceps and brachialis anticus, the condyloid ridges of the humerus. But it is not always true conversely, that where a large muscle is attached there must be a large osteophyte growth, ¢. g. there are none at the origins of the pectoralis major and sterno-mastoid, the supra- and infra-spinatus, the insertion of the -‘quadratus femoris, &c. One class of exceptions is, however, to be noted, viz: that at the attachment of those muscles and ligaments that are connected to epiphyses, there is generally no disease, ¢. y. the muscu- lar attachments to the greater and lesser trochanters, the greater and lesser tuberosities, tubercle of the tibia, the tuber iscbii and nearly all the ligaments. The epiphyses and their attached parts are very nearly all quite free from disease, though it may be largely developed in their immediate neighborhood. The direction of the nutritious artery seems to have had no influence ‘on the development of the disease either in its extent or degree. The porosity varies in its character, and usually any one bone will show all its varieties. 1°. The surface of the bone presents a very fine cribri- form appearance, resembling pumice stone. When magnified six or eight times this is seen to consist of a stout network of bone perforated by nu- merous small foramina, which are generally tolerably circular, and do not communicate one with another. (Fig. 24.) 2°. It may be of a finer vel- vety appearance. This by the same power is seen to consist of the same network of bone, whose very large foramina or meshes now communi- cate and are therefore very irregular in form, while the ridges forming the bony net-work are very thin and form relatively high walls between the adjacent meshes. Sometimes these ridges assume a tolerably regu- lar parallelism, giving a striated appearance to the part. 3°. A coarser appearance is often produced by a similar honey-combing with large foramina or meshes, deep and irregular, varying in size from a horse-hair to a line in diameter with the first or second variety existing in the inter- vening ridges. (See lower end of Humerus, Fig. 1.) 4°. The surface is -often pierced more or less sparsely by small foramina about the size of a shorse-hair. (Fig. 20.) The osteophytes vary greatly also in their character. In shape they D4 Pepper.) ~ t [Dec.2, are either pointed, flat, or clubbed, sessile or pedunculated. They fre- quently form larger or smaller scales, which cover more or less of the pone. They vary from the smallest size visible up to ? inch in length or 1 inch square. They are often compound, smaller ones growing from larger ones as a base. Imbrication is not unusually a marked feature, and whether imbricated or not, their direction or ‘“‘trend’”’ almost always follows that of the fibres attached at that point. This is very marked where adjacent muscles run in different directions, ¢. g. the flexor attach- ments of the radius and ulna as contrasted with that of the pronater quadratus. (Figs. 11 and 15.) The grooves between the osteophytes have sometimes rolling edges, sometimes are as sharp as if cut with a knife, and often lie closely together and parallel; they are apparently made in many cases by the numerous small vessels. All of the osteo- phytes are more or less porous. : The color is usually normal, but in some places is of varying shades of brown. On a section the whole bone is seen to be encased with anew formation of bone. This is true not only of the long bones but also of the scapule and ossa innominata. Viewing these bones and also many parts of the shafts of the long bones on the surface, one would suppose he.had simply to do with the original thickened bone which had undergone this porous change. But a section shows that there is a complete new formation which is added layer after layer around the old bone. These layers (except- ing where sclerosis has taken place) are separated by interspaces sometimes _ just appreciable to the eye, sometimes a quarter of an inch wide. (Fig.17). The outer layer is often very thin, but presents to the eye that deceptive appearance of apparent compact tissue which has simply become porous. Where sclerosis has taken place or osteophytes are developed, of course the thickness of the outer layer is either greatly increased or else unde- terminable. The other layers also vary in thickness from the develop- ment of the sclerosis from the thinnest possible to one or two lines. “These layers may sometimes be traced into continuity with those form- ing the healthy portion of the wall’ * of the original bone, especially at the extremities of the shaft. (Fig. 4.) At these points, starting from the ori- ginal compact tissue, the several layers of the encasing new formation grad- ually become more and more widely separated or new layers may appear, thus producing a very great thickening at the centre, while at the ends of the shaft the thickening gradually (sometimes suddenly) diminishes. The interspaces between the layers are sometimes for even an inch wholly void, but they are generally filled with intervening trabecule of bone, which form a cancellated tissue and also support the superimposed layer to which they are always perpendicular. To a very large extent these layers have been welded together by sclerosis, and sometimes the new growth and the origirial bone present no line of demarcation by which they can be distinguished. Where this solidification has taken place, the cut surface instead of the uniform ivory-like solidity of normal compact * Paget. Surg. Path. F Ed. 1863, p. 301-2, and fig. 40. OF 1870. ] a (Pepper. tissue presents a granular appearance, as if the cancelli of the interspaces were not solidly filled up. The process of sclerosis not infrequently dips down like a cone whose base is of considerable extent at the surface of the new growth and whose apex just touches, or is sometimes welded with the original compact tissue. (Fig. 21.) Eburnation has nowhere taken place. The original bone, too, has undergone marked changes. Its limits are generally pretty well defined, but the compact tissue of which its wall once consisted, is now cancellated, to a greater or less degree (osteo-spon- giosis). Sometimes all appearance of compact tissue, save a mere worm- eaten porous external film, has disappeared. Sometimes no cancellation appears, but the old and new growths are welded together. The cancelli of the once compact tissue of the old bone always run parallel with the aais of the bone, and are thus easily distinguished from those of the spaces between the laminz of the new growth which run at right angles to the surface of the bone. (Figs. 4 and 17.) The old cancellated tissue has often very large cancelli and in some cases has disappeared, leaving a wider medullary canal than is normal. The epiphyses do not appear materially altered on section. V. Description OF INDIVIDUAL BONES. 1. Head.—All the bones of the head are present, completely disarticu- lated. The spheno-occipital suture was not ossified. No sections were made of these bones, and the external appearances alone are described. (a) Frontal. The roof of the orbit, especially in the fosse for the lachrymal glands, is somewhat porous. Internally the porosity appears over various parts of the perpendicular portion. The irregular striated appearance from large numbers of fine grooves is marked, and sclerosis seems to have made considerable progress. (b) Parietal. Externally slightly porous at the posterior border ; in- ternally also over, say one-fifth of the surface, corresponding to the protuberance. (ec) Occipital. Externally small scattered patches of porosity ; inter- nally the same change is limited to the superior fosse and the groove for the left lateral sinus. (d) Sphenoid. Porosity of external surface of greater wings, and also in most of the pterygoid plates, which are somewhat thickened. (e) Temporal. Slightly porous and thickened externally on squamous portion, and in the glenoid cavity and in the grooves for both lateral sinuses. (f) Sup. Max. Slightly porous on anterior surface, and at the tuber- osity. The alveoli are reticulated so as to resemble almost the meshes of the pulmenary structure. (g) Palate. Internally, slight porosity at the junctlon of the perpen- dicular and horizontal portions. (h) Inf. Max. Ascending ramus markedly thickened, and porous in- ternally and externally ; most developed at the centre of the ramus ; Avr Sia Vv Ob Sil 1) In Pepper.] 26 [Dec. 2, body similarly affected, principally between the mental foramen and the external oblique line. Alveoli like those of the upper jaw. This bone has suffered more than any other bone of the skull. Condition of Teeth.—The teeth were all present, and were carefully ex- amined. They were very brittle, so as to break across with little difficulty (see Micros. Hx.), but presented no peculiarity of shape. The entire ab- sence of the peculiar deformity of the incisors, noted by Hutchinson, of London, as characteristic of hereditary syphilis, is to be especially marked as it bears upon the question of causation of the morbid process. 2. Vertebrw.—The epiphysal plates of the bodies, and the epiphyses of the transverse and spinous processes, are all gone. In the dorsal region the groove between the three original parts in which the ossification takes place, is very deep, but they are all united more or less. This groove gradually disappears both above and below, none of the remaining cervi- cal vertebree showing it, while inferiorily it is visible as far as the first sacral. On section the body is not much thickened, and no line of de- marcation exists. No sclerosis has taken place. (a) Cervical. Scarcely noticeable porosity of the anterior surface of body. Posterior arch of atlas is unusually thick and dense. (b) Dorsal. Marked porosity of external surface of body, which is elevated above the surface left by the removal of the slightly overlapping epiphysal plates, about one-half a line to a line. Spinous processes slightly porous. (c) Lumbar and Sacral. Same as dorsal ; the porosity of spinous pro- cesses being more marked. 3. Sternum and Ribs.—(a) The manubrium only is present, and is very thick and porous. No osteophytes. (b) The ribs have lost all their epiphyses. They are not affected on the external surface, save slightly in one or two instances. On the pleural surface they are all porous, and often a little thickened. For about one inch from the head the entire bone is thickened and porous. 4. Upper Extremities.—(a) Clavicle. The sternal epiphysis is wanting. Where the surface for the articulation with the acromion should be, there is on each side an oval cup-like depression } x 1 in, and 4 in. deep. (Fig. 13.) Its walls are perpendicular, its floor flat, and both are covered with a thin layer of compact tissue resembling that which covers all the ends of the diaphyses of the other bones next the epiphysal cartilage. It was filled, when first seen, with a small mass of dried tissue resembling the epiphysal cartilage already described. Possibly it may have been an unusual third centre of ossification for this bone. It was occupied, certainly, by some substance separate from the shaft of the clavicle, either a third centre of ossification, or a projecting piece of the acromion. If the former, it is a yery unusual place for a supernumerary epiphysis. The whole bone is thickened to about twice its normal width, and its surface is coarsely porous throughout. At the insertion of the ligaments on the under surface, the porosity is quite fine and velvety. At the inner half of the origin of the deltoid there are twelve to twenty stout and well 9 1870. ] 27 [Pepper. developed osteophytes. A few also exist at the middle of the insertion of the trapezius. The section shows the original bone distinct from the new growth at all points. The lamine of the new growth are very dis- tinct at most points. A large part of those of the under surface are more or less closely united by partial sclerosis. The original bony tissue is relatively but little altered. (b) Scapula. The coracoid process is one-third united to the bone, but wants the epiphysis developed on it at about seventeen years of age. All the other epiphyses are absent. The bone is porous throughout, save at the centre of the infra-spinous fossa ; generally of the coarse variety, but very five in certain spots. The whole bone is somewhat thickened, as can be seen without any section, at its posterior border and on the spine. (Fig. 23.) The latter being to a great extent denuded of the outermost compact, yet porous layer of the new growth, shows the reticulated trabecule which supported it, and through their meshes the old external compact layer of the original bone now all worm eaten and very thin. his is especially well seen at the two extremities of the spine. The axillary border of the bone is three or four times as thick as is normal, has a few coarse osteophytes, and a very deep and wide groove for the dorsalis scapule artery. (c) Humerus. All the epiphyses are preserved except that of the in- ternal condyle. The trochlear surface projects only to a level with the radial. The whole shaft (Figs. 1 and 2) is involved in the disease, the least at the upper fourth, the other three-fourths being about alike. The porosity is almost wholly very fine or velvety. About two inches below the head, at the insertion of the Pect. maj., the anterior bicipital ridge is greatly thickened (especially on the right side). It is continuous with a very large elevated surface (2 1} in.) at the insertion of the deltoid. This is covered with a large mass of not very large porous osteophytes whose trend is generally upwards. One (r. side) or two (left) large flat imbricated osteophytes mark the posterior lip of the bicipital groove. At the musculo- spiral groove, which is well marked, the bone is finely porous, but presents no osteophytes. At the lower third, anteriorly, the bone presents numer- ous osteophytes, sometimes single, but generally in groups. They are sessile, porous, and in some cases imbricated ; their trend is generally downwards, except just above the epiphysis, where they are at right angles to the bone. The two condyloid ridges, especially the inner, are greatly diseased. The external ridge (especially on the right side) has several large porous sessile outgrowths with intervening grooves, the largest groove about corresponding in position to the anastomotica magna artery. The internal ridge up to the insertion of the coraco-brachialis is covered with large knobby and porous, imbricated osteophytes, continu- ous witha similar remarkable growth on the posterior surface of the bone, covering the origin of the internal head of the triceps, which extends to the musculo-spiral groove above, and fades into simple porosity exter- nally. Atthe origin of the external head of the triceps, there is also a gee) 28 [ Dee, 2, Pepper. ] marked elevation covered with pointed osteophytes, and continuous with that of the deltoid insertion. The trend of all these osteophytes is down- wards, and their color (especially on the right side) is a light brown. The section (Figs. 8 and 4) shows the outline of the old bone obliterated in the lower third, and only faintly visible in the upper two-thirds ante- riorly. In the posterior upper two-thirds the lamin of the new growth are admirably shown, though even here the sclerosis is in some parts far advanced. The original compact wall in the superior one-third, anterior- ily, and two-thirds posteriorly, has almost disappeared, the cancellation (spongiosis) is so great, and it is a typical illustration of this process in various stages. The original cancellated structure is either fragmentary, its cancelli being very large, or else it has entirely vanished, leaving an enlarged medullary canal. (d) Radius (Figs. 9,10 and 11.) All the epiphyses are gone, save the left upper one. Instead of being rounded externally, and showing a sharp interosseous ridge internally, it is almost cylindrical, increasing in diame- ter from above downwards. At the bicipital tubercle there is a crest of curved osteophytes under which, as in a cave, the tendon of the biceps was inserted. The oblique line is marked by a series of knobby, porous, slightly imbricated osteophytes, whose trend is downwards and inwards till they reach the insertion of the pronator teres, where their size increases, and their trend is upwards and outwards. The interosseous border is rounded off and marked by a series of deep)y imbricated laminated osteophytes, all trending downwards, resembling a rounded surface deeply grooved by ob- lique parallel cuts of a thin saw. Where the pronater quadratus was at- tached, a large number of osteophytes exist in ridges, which run lat- terally. All the rest of the bone is thickened and porous, and where the muscles took origin, is covered with porous osteophytes. Tn section (Fig. 8) the outlines of the original bone are visible through- out ; the laminz of the new growth are marked ; the sclorosis is in various stages, and anteriorly for some two inches the new and old growths are almost welded together. The old compact tissue is wholly changed to spongy, and the medullary canal is increased in size. (e) Ulna (Figs. 14 and 15.) The lower epiyhyses are absent. Like the radius, the ulna is involved in its whole length, and is about twice its nor- mal diameter. At the insertion of the brachialis anticus, a cup-like depression surrounded by an elevated ridge of osteophytes, exists, somewhat similar to that on the bicipital tubercle of the radius. The anterior surface is covered with small porous osteophytes, witl a slight downward imbrication. At the attachment of the pronater quadratus they become more marked in their development, and the imbrication is external. The interossecus ridge is rounded off and marked, as in the radius, but with several unusually large and deeply imbricated osteophytes with a deep groove, probably that of the inter- osseous artery. Externally a brown discoloration is seen, which is the most noticeable on the rig side. Posteriorly the bone is coarsely 1870.] 29 [Pepper. porous, but very few osteophytes exist, save on the lower third. The intervening grooves run transversely, but are neither deeply nor sharply cut. On section (Figs. 16 and 17) the line of the original bone can be dis- tinguished throughout ; the laminew of the new growth are very marked ; the sclorosis has welded together all the new layers anteriorly, and at the junction of the upper and middle thirds, the new and old growths are almost melted together both anteriorly and posteriorly. The inter- space between the old bone and the first new lamina reaches one-fourth of an inch in width just below the olecranum, and the distinction between the perpendicular trabecule filling it up, and the longitudinal cancelli of the once compact tissue of the old bone is very marked. The medullary sanal is scarcely, if at all, enlarged, and, indeed, at the point of greatest sclerosis above named, the same process seems to have invaded the canal itself. 5. Lower Extremities.—(a) Innominate Bones. The ilium is separated from the ischium and pubes, which are firmly and indistinguishably united together at their rami, but at the acetabulum are distinct. The Y-shaped piece uniting them is preserved, andis loose on both sides. All the other epiphyses are missing. The bones are porous throughout but not to a marked degree. The thickening varies from } to 3 of an inch, being greatest just above the acetabulum. On the ischium and pubes no osteo- phytes exist, save one small lamina on the body of the right pubes. The ilium is free from them except above the acetabulum for a considerable space, on and around the reflected origin of the rectus, where large and strong osteophytes exist, with a trend inwards and upwards. On section of the ilium, (Fig. 12) the external surfaces, which other- wise would be thought to be the porous surface of the original bone, are seen to be the outer layer of the new growth. The original compact tis- sue has undergone spongiosis to a great extent. Sclerosis is furthest ad- vanced just above the acetabulum. . : (b) Femur (Figs. 6 and 7). All the epiphyses are separated. Both heads and great trochanters and the left lower epiphysis are preserved. The latter shows some very slight porosity, as already noticed. Anteriorly the inter-trochanteric line is marked by a well developed growth of short, thick, rather acuminate osteophytes, separated by grooves running in the axis of the neck. A similar line of more slender imbricated osteophytes runs parallel to the base of the great trochanter and trends toward it. These two lines form the letter A. Immediately within this letter A (especially on the left side) the trend of all the osteo- phytes turns sharply downwards and so continues to the lower j of the bone, where they are perpendicular. They are not very marked in their development. Just above the end of the shaft, however, they form an Overlapping sheath to the bone. In the middle of the right femur an aperture (14 X 2 inches) exists in the ensheating new growth, disclosing ay 30 [Dee. Pepper. ] to view the original but altered bone. Posteriorly the osteophyte growth extends from half an inch below the lesser trochanter to within 2} inches of the end of the shaft, and the same sheath-like appearance is very no- ticeable at its two extremities. Where not covered with osteophytes, the shaft is very finely porous and thickened. All the central two-thirds of the shaft is one vast mass of large, irregular, porous osteophytes. Their di- rection is not constant, but is in general downwards, and their shapes are very varied. The massextends for about eight inches, along what was the tolerably sharp linea aspera, but is now about } in. wide and about ¢ inch thick. The posterior inter-trochanteric line and great trochanter are not affected, except a slight porosity in the former. The lesser trochanter is wanting, but for } in. around it there is no disease beyond some porosity save one squamous osteophyte on the right side. On section (Fig. 5) in the axis of the head and great trochanter the out- line of the old bone is not to be made out save internally, and then only imperfectly. The old and new growths are almost everywhere indistin- guishably welded together. The lamine of the new growth, too, are welded together save at a very few points. The old compact wall is still solid, but it looks granular and does not present the ivory-like solidity of normal compact tissue. The medullary canal is somewhat enlarged at the expense of its walls. At the lower extremity the trabeculw of the can- cellated substance are normal, but in the head and neck the arches for mechanical support are much less distinctly marked than is usual. (c) Patella. The right patella is missing. The anterior surface of the left shows a few osteophytes trending downwards. (d) Tibia. Both the upper epiphyses are preserved. The whole bone is greatly diseased and thickened to about twice its usual diameter. The tubercle is slightly thickened and presents a ragged edge above for articulation with the epiphyses, but the greater part of the tubercle being developed from the epiphyses the disease is not very marked. The crest is rounded in its whole length and porous. The internal sub-cutaneous surface presents marked syelling and porosity. There is but little oste- ophyte growth, and it is generally in the laminz except at the sartorius insertion, where it is more developed. A number of deep grooves exist, generally longitudinal in their direction and most marked at the upper third. The posterior and external surfaces are covered with a warty growth of porous osteophytes which attain their greatest development at the interosseous border and especially at the oblique line. The gen- eral trend of all this growth is downwards. Grooves for the vessels are frequent and tolerably deep. : On section (antero-posterior) the outline of the old bone is distinct at the extremities, but in the central two-thirds it is barely visible in front and wholly lost behind, the sclerosis at this part having welded together all the lamine of the new growth and the original bone. Even at the ex- tremities the new lamine are not very marked. The rarefaction of the original compact substance is of course therefore not marked. The me- dullary canal if at all altered is narrowed by the encroaching sclerosis. 1870. ] 31 [ Pepper. (e) Fibula (Fig. 18). Its shaft alone is preserved, and its axis iS: slightly bent inwards. The whole bone is encased in a newly formed os- seous growth which is sometimes simply porous, and is covered with sometimes an interrupted, sometimes a continuous, growth of warty osteophytes, all more or less porous. Posteriorly and internally this growth is most developed, the trend being downwards. The lower sub- cutaneous surface is greatly thickened and finely porous, but has no os- teophytes. On section the bone is doubled in its diameter, the outline of the original bone being only visible in about ene-half of its extent, the scle- rosis obscuring it at other points. The original compact tissue is rare- fied by spongiosis, and the medullary canal is somewhat widened. (f) Hand and Foot. They are considered together, as some of the bones are indistinguishable, and moreover, in general the same descrip- tion applies to both. (1.) Right scaphoid of hand. Not diseased. (2.) Left calcis. Porous and enlarged throughout. Porous osteophytes are seen at the attachments of the tendinous sheaths internally, and one large flat one on the inferior surface. The epiphysis for the attachment of the tendo achillis is preserved, but shows no disease. (3.y Metacarpus, metatarsus and phalanges. Two of the phalanges have their epiphyses attached but not united by ossification. The epi- physes are not diseased. No other epiphyses are preserved. All these bones suffer by far to the greatest extent in the centre, not at all at the head (viewed externally), and but little at the base, and the new growth is five or six times as thick on the dorsum as on the opposite surface. No: osteophytes exist save on one of the metatarsal bones and at the ridges for the flexor sheaths of three of the phalanges. On section (Fig. 21), compare also Fig. 22, the outlines of the old bones are very readily seen, the apex of the conical sclerosis having, at points, just touched the surface of the old bone. The original wall of compact tissue is wholly rarefied by spongiosis, and the cancelli of the new and old bone are readily distinguished by the different directions of their axes. The normal compact wall of the phalanges being very thick relatively, the changes in it are the more marked. Sclerosis has invaded from half to two-thirds of the new growth. The head of the bone is also markedly rarefied by spongiosis. MICROSCOPIC EXAMINATION. The specimens from which the following description and wood-cuts were made, were prepared with his well known skill by Dr. J. H. MeQuil- len. They consisted of a transverse section through the thickened wall of a phalanx, embracing the thickness of the layers superimposed by the pe- riosteum, but not of the entire original compact layer of the bone, and of a transverse section through the right canine tooth. Q«¢ 2 Pepper. ] ied [Dee. 2, The section of the phalanx (Fig. A) exhibited a quite compact osseous structure—the Haversian canals being for the most part round, and rather small, though in some places they were irregularly shaped or oval, and larger. The intervening bone lamelle were of unusual thickness, fh A \ I yy ‘ and presented in the majority of cases, bone corpuscles with canaliculi. In some cases, however, no bone corpuscles were present, and the lamellze appeared to be merely calcified by saturation with bone salts. : The bone corpuscles were small and often indistinct ; in some places they were unusually round, but in others they presented the normal elongated shape; their canaliculi were invariably very poorly developed, and often could not be discovered. With regard to the mode of arrangement of the bone lamellw, they were always developed concentrically with (parallel to the walls of) the Haversian canals, and in no instance were any lamelle found whose di- rection was parallel to the external surface of the shaft. egg 38 1870.] — [Pepper. The section of the tooth (Fig. B) showed the existence of numerous ir- regularly shaped, branching lacune in the dentine near the marginal layer of enamel. These spaces were of various sizes and intercepted the Fic. B. course of a varying number of dental tubuli. They indicated unquestion- ably either an arrest of the process of calcification of the dentine, or of the resorption of calcareous matter already deposited, conditions which are also present in the true bony tissue. They are identical with the so-called interglobular spaces first described by Kolliker and carefully studied by Dr. McQuillen of this city, who has published (Dental Cosmos, N. 8. Vol. VIII, No. 3, pg. 113,) several excellent illustrations of them. PATHOLOGY OF THE DISEASE. Having thus described the gross and minute features of these bones, we would hazard the following remarks in regard to the nature and cause of the pathological process :— Tn the first place it is to be observed that three separate processes, or at least three distinct stages of the same process, are represented in dif- ferent parts of the skeleton, or even, in some instances, in single bones. These stages are : First. Internal Osteoporosis of the original osseous tissue. 2d. Ex- ternal Hyperostosis, due to successive attacks of Periostitis, both of which processes are present in varying propertion in almost all the bones, and 3d. Secondary Induration. A. P. §.—VOL. XII—E Pepper.] 3b4 [Deez2, 1. It is especially in regard to the explanation of the internal osteopo- rosis, which constitutes so marked a feature of these specimens, that we regret the absence of any careful examination of the bones in their recent condition. Jn their present state, it is only possible to describe the de- gree to which this rarefaction of the osseous tissue has occurred, but it is evident that such changes might be produced by very varied alterations of the medulla and bone corpuscles. Thus, among the recognized causes of osteoporosis, may be mentioned syphilis, scrofula, rheumatism ; qnd, in addition, we must add that both osteomalacia and simple ostitis pro- duce changes in the bones which, after the specimen has been boiled, and the organic matter entirely removed, are not to be distingushed from the effects of the first mentioned diseases. In each case, under the action of the morbid irritant, whether purely external and local, or internal and con- stitutional, there is more or less rapid proliferation of the essential vital elements of the osseous tissue, called bone corpuscles or cells. At the same time, the bony lamin surrounding the Haversian canals, and the walls ef the lacunse, are progressively deprived of their calcareous salts and removed, while the enlarged spaces thus produced are filled by the con- stantly growing cellular elements. The manner in which this removal of the caleareous salts is effected has been, and indeed remains, a subject of much discussion. The first idea which seems to have been entertained may be inferred from the name, eccentric atrophy, which was given to many specimens of osteoporosis, under the belief that the bony lamelle were thinned and pushed asunder by the centrifugal pressure of the growing medulla. There is, however, no evidence whatever in favor of such a mechanical explanation, and this hypothesis has justly been almost uni- yersally abandoned. By far the most plausible explanation which has been advanced appears to be that the removal of the calcareous salts, the first essential step in the destruction of the bony lamelle, is due to the solvent action of some acid elaborated by the bone cells during the inflammatory process. Ac- cording to Weber, their removal is not due to the direct action of any acid, but is owing to a gradual conversion of the insoluble trt-basie phos- phate of lime into the more soluble b2-basie salt. As this feature of rarefaction is, however, common to so many diseases of the bones, it is evident that the most characteristic results of such dis- eases are to be rather found in the condition of the bone cells, and in the characters of the morbid product which has resulted from their multipli- cation. And it is to be trusted, that by careful chemical and microscopi- cal study of these, such peculiarities will be discovered as will enable us to distinguish with certainty in recent bones the various morbid changes. Heretofore the majority of observers have limited themselves either to a description of the dried bone, after maceration or boiling, or at most, of the general characters of the medulla with which its cancelli are filled. And it results from this swperficial mode of study, that there is as yet but om geninn cm, aise mene iil “ 7 mes — Or 1870.] 39 (Pepper. little exact knowledge of the really essential changes which the organic, active portions of bones undergo in disease. Virchow, who was among the first to examine microscopically the con- dition of the bone cells in ostitis and some other diseases attended with rarefaction of the bone tissue, (Uber parenchymatése Entziindung ; Virchow’s Archiv. Bd. IV. Hft. 2: 1852, b. s. 801 to 311,) formerly regarded the process as essentially a degenerative one, due to the fatty degeneration of the bone corpuscles and the subsequent softening and removal of the area depending on these cells. We have already, how- ever, stated the view which appears most plausible in regard to the re- moval of the calcareous salts, and so far from fatty degeneration of the bone corpuscles being a constant feature in the different forms of osteo- porosis, it would appear from the careful researches of Ranvier (Archives d’ Anat. et Phys., Norm. et Path., No. 1, 1868, page 69), that this condition of the cells is altogether characteristic of caries and limited to that morbid process. On the other hand, there is every reason to presume that these cells are influenced by various morbid ‘causes, (inflammation, syphilis, rheumatism, gout, scrofula, &c.) in the same way as the other tissues of the body, and give rise to products more or less characteristic of the dis- eased action present. The history of the present case would appear to indicate that the na- ture of the disease was a rheumatic or scrofulous inflammation, but beyond this mere supposition we are prevented from advancing by the absence of any chemical and microscopical examination of the recent bones. We would here again call attention to the marked peculiarity of the porotic bones, fully described at pages 24 and 25, and figs. 4 and 17, al- though we are unable to suggest any plausible explanation of the invaria- bly parallel arrangement of the meshes of the porotic bone, and of the equally uniform vertical arrangement of the meshes of the new-formed sub-periosteal layers. 2. Another important appearance present in the bones here described, and indeed one which is as marked and wide-spread as the osteoporosis, is the extensive development of bone upon the exterior of the original shafts. In our description of the skeleton, we have already noted the peculiarities of these sub-periosteal growths, and it will be remembered that they are in every instance limited to the body or shaft of the bones, and never extend on to the epiphyses, and that they usually present sey- eral thin lamine of imperfectly compact bone, parallel to the shaft and separated from it and from each other by more or less wide interspaces usually occupied by coarse cancellated tissue. lt is undoubtedly from the examination of such specimens as this that the mistaken idea arose that the lamelle, of which the original compact shaft was formed, had been pushed asunder by the great enlargement of its cancelli. It will, however, be seen from our description that the ap- Pepper. ] 36 {Dec. 2, 1870. pearances contradict any such supposition, and clearly show that while in the cancellated and imperfectly compact tissue of the original shaft a process of rarefaction (osteoporosis) has been advancing by atrophy of the bony lamelle, there has also been an active process of periostitis re- sulting in the formation of thick layers of new bone on the exterior. Another means of distinguishing the line of demarcation between the original shafts and the new-formed layers, is the abrupt change in the direction of the cancelli already referred to. It isevident, also, that the periostitis has not been uniformly continuous, but that for a variable time its intensity was such that the inflammatory product was capable of but imperfect ossification, and remained as cancel- lous tissue ; while at irregular intervals thin layers of imperfectly com- pact tissue have been formed. The occurrence of this long standing, but not uniform process of periostitis ossificans appears to account, in every instance, for the changes observed on the exterior of the original shafts. In addition to this uniform hyperostosis, it will be observed from the de- scription (see pp. 23, 24) that the same process of periostitis has given rise to varied forms of porous osteophytes. 3. In some places, however, it is evident that a still further change has occurred, consisting in the gradual conversion of the cancellous tissue into compact bone. This process of consecutive or secondary induration is most marked in the layers of bone formed by the periosteum ; though it is present in the shafts of the tibie, femora and some other bones. It is manifestly impossible to determine accurately the portions which have been rendered compact by this process, but the disposition of the successive layers of new-formed bone is, in general, so much like that above described, that we are inclined to regard all the areas of compact bone of any considerable thickness as due to this secondary change. It would, indeed, appear but probable that as the high degree of inflam- mation, under which the layer of cancellous tissue had been formed, sub- sided, there should be a tendency to the formation of successive layers of bone on the interior of the walls of the cancelli. It is especially in con- nection with this point that the result of the microscopical examination of the sub-periosteal layers is of so much interest. It will be observed (see Fig. A) that in the newly-formed compact bony tissue, the lamella are arranged concentrically around the vascular canals; a mode of ar- rangement which strongly points to the occurrence of the process of con- secutive induration, as we have above described. The specimens are deposited in the Museum of the College of Physi- cians. J. EWING MEARS, M. D. WM. W. KEEN, M. D. HARRISON ALLEN, M. D. WM. PHP PER, Mi D. ‘ | Stated Meeting, March 3, 1871.

There is still a lingering skepticism on the part of some meteorologists, regarding the moon’s influence on the weather, a skepticism which is perhaps owing to the apparent want of agreement between observations at different places. There is, however, no good reason for expecting such accurate correspondence as is sometimes deemed essential. Dr. Emerson (Proc. A. P. S., XI. 518) has communicated to the Society his early ob- servation upon the reversal of the European barometric prognostics on this side of the Atlantic. Mr. Blodget (Climatology, pp. 221-257) has pointed out various climatologic contrasts, and Mr. Scott, the Director of the British Meteorological Office, has noticed an opposition between the solar (or temperature) rain-falls in Western Europe and Eastern America, analogous to that which I have indicated in the lunar rain-falls. The confirmation thus afforded to the results of my previous investigations, strengthens the presumption that, in our Atlantic States, signs of fair weather may be most confidently trusted during the ten days preceding, signs of rain during the eight days following, full moon.

By Puiny EarLE CHAse. The signal service observations of our War Department have already N shown the value both of Buys Ballot’s law and of Capt. Toynbee’s modi- fication in predicting changes of wind, especially if due regard is paid to the barometric variations of the two previous days. They have also suggested the following general deductions, some of which may perhaps prove to be true only of the winter, while others seem to be explicable by natural circumstances of position and physical configuration, which must be operative at all seasons. 1. Winds varying like the land and sea breezes, are often traceable, especially in the lull which follows the passage of storms, to differences of temperature in the neighborhood of the great lakes, and of mountain peaks and ridges. 2. The wind, especially in the Southern States, often blows directly in the line of the greatest barometric gradient. But even in such cases, after a few hours continuance, it tends towards the azimuth indicated by Buys Ballot’s law. 3. The isobaric lines are, therefore, often of less relative importance than the gradients in forming forceasts. 4, Long ridges of high barometer, as observed by Espy and others, with adjacent troughs of low barometer, often traverse the continent, sometimes with slight defiection, sometimes having a semi-circular, cireular, or elliptical curvature with a diameter of three thousand miles or more. Such ridges usually have a steeper declivity and stronger winds on their northerly and easterly than on their southerly and westerly sides. 5. Currents with an anti-cyclonic tendency, controlled by arreas of high barometer, are notably common. Reversals of wind, asfrom N. E. to8. W.., are, therefore, frequent after the passage of an anticyclonic ridge or cen- tre, as well as after the passage of a cyclone. 6. Our recent storms have been anticyclonic, and there seems some reason for supposing that anticyclones are the usual “ weather-breeders,’” even of such of our land storms as become more or less cyclonic after they are fully developed. 7. The precipitation of vapor of course gives rise to local cyclones, which, however, may be easily and speedily overborne by the grand anti- cyclonic whirls of a half million miles or more in area. ’ 8. These and other peculiarities, point to a probable origin of storms in the blending of polar and equatorial currents, near the latitudes at which the general tendency of the winds changes its direction. 9. Mr. Scott has observed that when polar (E.) currents are blowing at. the North, and equatorial (W.) currents at the South, a serious baro- metrical disturbance, frequently resulting in a gale, generally soon fol- lows ; but when the polar current is at the South and the equatorial at the North there appears to be no law of sequence. The latter condition, with us, seems often indicative of approaching fair weather, especially if northerly or easterly are separated from southerly or westerly winds by a ridge of high barometer. : 10. If the progress of a northerly or easterly current towards the equa- tor is impeded by an intervening southerly or westerly current, the dis- turbance not only speedily follows, as indicated by Mr. Scott, but it is also, commonly, like most showers, 8. JJ. storms, and other marked cyclonic commotions, of briefer duration than those which are primarily anti- cyclonic. ; Hs, mh March 3, 1871.] 41 [Cope.

LIoDON sECTORIUS, Cope, sp. nov. : Established on a large part of the under and upper jaw, and other parts of the cranium with a vertebra, from the green sand of the upper bed of the Cretaceous of New Jersey. The character which at once distinguishes this species from other Liodons, and especially from all the species of Mosasaurus, is the very compressed’form of the crowns of the teeth, which approach nearer in this respect to those of Diplotomodon, than any others that I have seen. The vertebra, a lumbar, has also subround articular faces, thus removing , the species from close relationship to those with depressed vertebra, of some of which the teeth are unknown. In the presené specimen crowns and _ pedestals of thirteen teeth are pre- served. Those of the mandible are most numerous, and display the suc- cessional modification of form from before backwards visible in other species of the family. The anterior teeth are less compressed, and have ALP. 8.——VOL S11? Cope. ] 42 {Mareh 8, but one, an anterior, cutting edge, the posterior face being regularly convex. The inner face is much more convex than the outer, and the flatness of the latter is marked at the apex of the tooth by a short ridge which bounds it posteriorly. This is a trace of the bounding angle which extends to the basis of the crown in Mosasaurus. The anterior cutting edge is in profile convex ; the posterior outline concave to near the tip. The cutting edge is acute, and beautifully ribbed on each side, but not properly denticulate. The surface of the tooth is not facetted, but the outer face exhibits the peculiarity of a longitudinal coneavity, or shallow groove extending from the base to the middle of the crown. The enamel is polished, but under the microscope minutely and extensively striate: ridged. This description is taken from the second or third from the anterior end of the maxillary bone. The third from the distal end of the dentary is very similar. The crowns become rapidly more compressed as we pass backwards. From a broad oval section of two crown bases, we reach a flattened oval crown, with the cutting edge sharp behind as well as before, and minutely ribbed. ‘The crown is not facetted, and is more convex interiorly than exteriorly. The exterior convexity is chiefly anterior ; the posterior face is slightly concave from the open groove already described as present in the anterior teeth. In two posterior crowns, one still more elongate in section, the external concavity becomes flatter and includes a great part of the outer face. A tooth still more posterior presents the peculiarity of the species in the strongest light. The crown is still more compressed, directed backwards, and only .25 higher than wide antero-posteriorly at the base. The latter is a little over twice the transverse diameter just behind the middle. The surface presents the characters described in others. The outer concave surface is wide and shallow, and contributes to the attenuation of the posterior half of the tooth rather than the an- terior, which is consequently thicker. The cutting edges are sharp, the anterior convex and retreating backwards to the rather obtuse apex ; the posterior convex above, concave below. The exposed parts of the dental pedestals are frustra of cones, neither swollen nor concave. Measurements. M.

The cotylus descends abruptly behind it. The coro- noid bone exhibits the usual anterior fissure. ‘The rolled front margin of the ascending portion is thickened. The superior surface of the anterior part of the frontal bone, is lumpy and with some shallow pits ; the outer face of the articular is smooth. The vertebra preserved is a posterior lumbar, and is injured; the anterior articular face is nearly round. Its vertical diameter is M.058. Length of centrum M.008. The forms of the teeth distinguish the Liodon sectorius from the species of Mosasaurus, and that of the vertebra, from such species as Liodon perlatus, Cope, and L. dyspelor, Cope. There remain to compare with it, L. proviger, Cope; L. mitchillii, Dekay ; L. laevis, Owen; L. congrops, Cope; L. tetericus, Cope; and L. mudgei, Cope. In size it will only compare with the first two species, being from twice to four times as large as any of the remaining four. The flattened teeth distinguish it a once from JL. éetericus, and the abrupt rising superior margin of the articular bone, from the L. mudget, where the upper and lower margins are for some distance parallel. The less compressed vertebral centrum distinguishes it from ZL. laevis. From the two large species, dental characters separate it. Thus in L. proriger the teeth are less compressed, and are facetted, especially the anterior ones, with concave grooves sep- arated by obtuse ribs. In IM. mitehillit the teeth present more similarity, but are abundantly distinct. They are much less compressed, even where the posterior cutting edge is strongly developed, the external face is con- vex to the apex and without concave or flat facet ; it is narrower at the base as compared with the height, and has an incurvature not seen in this Liodon. The enamel is smooth, and not striate under the glass. This and the L. miichillé ave the largest Liodons of the Eastern cre- taceous. I have recently obtained three anterior dorsal vertebrae and a tooth of the latter, from the lower bed of cretaceous green sand near Freehold, N. J. The vertebrie rival in size those of Mosasaurus dekayt, but are of a more elongate form. The articular extremities are cordiform oe and nearly round, the posterior with the smooth neck band just in front ofits margin. In front of this, the surface is sharply striate, especially on the inferior aspect ; the same appears on the bases of the diapophysis. The tooth is like one of those described by Leidy. (Cret. Rept. Pl. XI.) * The Léodon sectorius was obtained by Judson C. Gaskill, from the marl pits of the Pemberton Marl Co., at Birmingham, N. J., and liberally placed at my disposal by him. ADOCID A. The species of this family display considerable differences in the nature of the sutures of the bones of the plastron. In the thickest species the sutures are fine and the processes very small. This is especially the case with Adocus pectoralis. In .A. beatus which is thinner, the sutures are coarser, but without gomphosis ; that between the hyo- and hyposternal elements looking as though a slight mobility existed in life, as I have 44 Cope. ] [March 3,. observed in a former article. In A. syntheticus the sutures are a little coarser, and in A. agilis a further increase is seen, but with but little gomphosis. In A. pravus, according to Leidy, there is a little gomphosis, but how much is not ascertainable from his figure and description. In Homorophus insuetus, a stouter turtle, the gomphosis is very strong, especially in the longitudinal sutures, where the teeth are long and stout. In Zygoramma this coarseness of gomphosis reaches a maximum, being strong in all the sutures of the two species, except the anterior meso- sternal of ZYGORAMMA MICROGLYPHA, Cope, sp. nov. This large species is represented by the greater part of plastron and ° half of carapace, with four marginal bones, ‘of an individual from the New Jersey cretaceous, of two and a half feet in length. Its discovery is interesting as enabling me to refer this genus to the Adocidw without doubt, a point which the specimens of the original species, Z%. striatula,. Cope, left uncertain.* The episternal bone displays beautifully the wide intergular scutum separating the lateral reduced gulars. The postabdom- inal bone displays the swellings corresponding to the pubis and ischium. The pectoral dermal scuta advance medially on the posterior part of the mesosternal bone. These characters are those of Adocus. On the other hand there is not satisfactory indication of the intermarginal seuta, though they may exist, and the free marginal bones anterior to the bridge display the double articulation, by suture and gomphosis characteristic of Zygo- ramma. It might be here observed that it is possible that this structure will be found tu exist in + pecies at present referred to Adocus, A. agilis, for example, where the marginal bones are unknown. This species is one of those in which the mesosternal is received in the very open emargination of the hyosternals, a character indicating the breadth of the former, and seen in A. agilis and A. synitheticus. The bones are relatively thin, the marginals light and gently recurved. The anterior lobe of the plastron is truncate, the straight anterior margin grooved lengthwise. The posterior lobe is regularly contracted; and rounded, and with thin edge. The xiphisternal and hyosternal of the right side have each an oblique sutural union with the hyposternal of the “left. The mesosternal is broader than long, the posterior margin broadly truncate, the latero-posterior curved sigmoidally, the anterior regularly convéx. The episternal is but moderately thickened. The parts of thé hyposternals on the bridge are nearly in the plane of the rest of the plastron. The marginal bones near those of the bridge have a thickened shoulder above within, into which the slender costal processes are received : they thin out rapidly and are gently everted distally. More distal marginals are lighter and more everted. , The bones of the carapace include three vertebrals and numerous costals. The latter display very weak capitular processes, but in none are they entirely absent. Neither they nor the vertebrals are thickened. The * Proceed. Amer. Philos. Soc., 1870, 559. 1871] A [Cope. vertebrals are short coftin-shaped, concave or emarginate in front; a stout laminar neural spine supports the vertebra below. The sculpture of all the bones is a delicate impressed punctation, the impressions forming lines or delicate grooves in some places. These run obliquely across some of the costals and marginals, and sublongitudinally on the posterior lobe of the plastron. The corneous scuta have left dis- tinct impressions. The marginals extended on to the costal bones at the place of the free marginal bones. The vertebrals were a little longer than wide, with bracket shaped lateral sutures, and openly emarginate below. The intergular plate was pentagonal, with straight sides, and broader -than long. The gulars are short and not prolonged very far on the outer margin of the plastron. The pectorals are narrowed laterally, and present a convex median outline on the mesosternum. The abdomino- femoral suture crosses a little behind the middle of the hyposternal bone. The median longitudinal suture winds from side to side on the posterior lobe in the most erratic fashion, abnormally no doubt, and the suture for the anals is anterior, convex in front, sigmoid at the sides.

It also differs in some respects which might be attributed to age, as the greater recurvature of the marginal bones and the greater ex- tent or prolongation of the thickening on the inside of the marginals next the bridge. But there are others which appear to be specific. Thus there is very little evidence of cross-union of sternal elements in the Z. striatula, and the sculpture is twice as coarse and so much more marked. Cope.] 46 [March 8, The pegs of the costal gomphosis are absolutely twice as large, and relatively still larger. I therefore believe this specimen to represent another species, Besides the sutural characters, those of the intergular scuta separate this species from Adocus beatus. In the latter that scute is urceolate, and the gulars sickle-shaped, being produced backwards on the margins ‘of the episternal or clavicular bones. In A. syntheticus the intergular is narrower, and convex behind, the mesosternum is angulate * posteriorly, and the plastron much thicker. In » Y 1871.] a [Cope. The caudal marginal is strongly concave below, convex above, the margin little recurved. The anterior outline is convex medially, with straight continuations at right angles to each lateral suture. A portion of the edge is broken off. Lateral marginal strongly and openly emar- ginate, surface not convex as in the median. Both are massive as in Agomphus firmus and allies. The union with the pygal ceases behind the costal pit. The costals ave thick and considerably curved transversely to the verte- bral axis, the rib heads are unusually large and prominent and sub- cylindric in section. The rib-ridge is more elevated and rounded in section than in any other species. The hyposternal is from the left side. It exhibits the free articulation for the xiphisternals; the posterior margin is thinned out, while the anterior is more abruptly rounded, and without trace of hyosternal suture. The external face is distally rayed with narrow ridges. The common peduncle of the scapula and procoracoid is short and wide, the sutural face for the coracoid, subtriangular. The bicipital ridge of the humerus is as usual at right angles to the head, and is thin and flat. The plane of the inner crest makes an open angle with the outer; its base is less distant from the shaft than that of the outer. The great trochanter diverges somewhat from the plane of the axis of the head of the femur. The latter overhangs the shaft be- hind ; the latter is curved, and beyond the middle subquadrate. In this as in the humerus, one of the two crests is continued-as a ridge along the shaft. Measurements.

This species was discovered by John G. Miers, a gentleman who has already enriched paleontology with many interesting forms. From the upper bed of Cretaceous green sand at Hornerstown, New Jersey. In the nomenclature of the elements of the plastron of the Testudinata, I will in future adopt in part that proposed by Parker (on the shoulder girdle Roy. Society, 1869), who has shown after Rathke that the posterior pieces do not belong to the sternum. The bones from front backwards should then be named, clavicle (‘‘episternal’’), mesosternal, hyosternal, hyposternal, and postabdominal (‘ xiphisternal ’’). CROCODILIA. BovrrosauRUsS MACRORHYNCHUS, Harlan. C. harlant, Meyer. Bottosaurus harlani, Agass., Leidy, Cope. The present state of knowledge of this rare species and genus involve some confusion, and I propose here to set it to rights in a brief manner. This is rendered easy by the discovery of the almost complete skeleton of a nearly grown individual, in the upper bed of cretaceous green sand. Following my predecessors, I regarded the Crocodilus basitruncatus of Owen as this species, in the synopsis Batr. Rept. N. Am., 1869, p. 65, but with expression of considerable doubt. At page 281 of the same work, I distinguished the species of Owenasatrue Jolops. As I had sup- posed the cervical vertebre to present the characters of Holops, the assignation of the specimens on which this opinion was founded to a species of that genus, left an entire uncertainty as to their character in Bottosaurus. 'The discovery of a series of vertebra as above mentioned, settles that their structure is not that of the other cretaceous genera, but that of the Tertiary and recent forms, 7. ¢., that the hypapophysis of the cervicals are produced and undivided to the axis. Deducting the errone- ously supposed character, there remains one curious feature to distinguish this form from the recent Alligator. The fangs of the teeth posterior to the eleventh are not enclosed by the dentary bone, but are exposed to the inner face of the splenial. How far the latter protects them the nature of the specimen does not allow me to decide. It remains to correct the specific relations of this crocodile. At page 230 of the above work, I described a new species of Bottosaurus, under the name of B. tuberculatus, establishing it on remains of cranium of one individual and those of the posterior parts of a skeleton of another. The anterior part, with jaws of the latter having fortunately been recovered macy oe 1871.] 49 [Cope. as above mentioned, and placed in my hands, I find that the animal be- longs to the original B. macrorhynchus, and that the first jaw and teeth represent an individual of another species, which will bear the name of B. tuberculatus. It differs from the first named in the acute or conic form of the crowns of some of the teeth, and probably in the much smaller size. In addition to the generic peculiarities already mentioned, this species exhibits a disparity between the lengths of the centra of the lumbar and cervical vertebra, which is unusual; compare the measurements below with those given for the remainder of the same animal as above cited. The hypapophysis of the dorsal vertebre are long, with parallel sides, and oval in section. In that one where the capitular articular face is near the suture of the neural arch, the articular cup is entirely round, and its margin flared out regularly to the capitular surface. The neura- pophyses are narrow, and the anterior zygapophyses directed very obliquely downwards. The cervicals are not only shortened, but diminish very much in diameter anteriorly, and the cup continues round. The hypapophysis is very stout on the anterior, more compressed on the posterior vertebrae. | The neurapophysial articular faces have the usual rugose anterior and | radiate crested posterior areas, but are short and wide, and the anterior area has an oblique concavity extending across it outwards and anteriorly. The posterior area is, however, the more deeply grooved, especially on the lumbar vertebree. The rami of the mandible ave preserved nearly entire. The large ex- ternal foramen between the dentary, angular, and articular bones, exists as also the smaller one on the inner face of the ramus. The rami are hollow and thin walled, though of very stout form. The anterior teeth extend along the outer margin of the dentary and then cross to the inner side, the teeth from the twelfth to the eighteenth or last being separated, the first by rudimental septa the latter by mere low ridges. Six of these teeth are exposed without osseous wall on the inner face, and that for the anterior tooth is probably incomplete. The whole length of the ramus is about twenty-eight anda half inches. It is elevated at the position of the tooth usually called the inferior canine ; this may be made to appear like an external expansion by rotating the ramus outwards (see Leidy Cretaceous Rept. U.S., Tab. IV. fig. 20). There is another elevation at the seventh tooth behind this point, and a concave eurve to the elevation of the articular bone. The angle of the jaw is prominent. The cutting edge is rather obtuse and delicately ridged transversely ; the rest of the crown » is rugose-striate. Measurements. Length ramus mandible......

Gaskill for the opportunity of examining this interesting fossil. DINOSAURIA. HADROSAURUS CAVATUS, Cope, sp. nov. This species is indicated by remains derived from the upper green sand bed of the upper Cretaceous of New Jersey. They belong to an individ- ual of the gigantic proportions characteristic of the four known species of the genus. It is smaller than ZZ. tripos or H. occidentalis, and in a less degree smaller than the I. foulkei, 'The remains consist of four caudal vertebrae from the median part of the series, three of them exhibiting rudiments of the diapophyses. In two of them the neural arch remains, one with the spine, and the articular prominences for the chevron bones are nearly complete. The first character which is observed in these vertebree is their opistho coelian articulation. The posterior concave face is marked by a more or. less prominent elevated band descending from the end of the floor of the neural canal, and which is sometimes grooved medially. The convex ex- tremity is swollen in the middle, most especially so at three points, and a groove or depressed band which has less than one fourth the width of the centrum, extends round the margin outside of it. The general form of the extremities is rounded hexagonal, the anterior a little depressed, the posterior alittle compressed. The sides of the centra are quite concave. The chevron articular projections are quite prominent, terminating ante- 1871.] 51 [Cope. riorly in a low ridge which extends to near the artterior face. At the latter position chevron articuar faces are either wanting or very little marked. The centra exhibit no lateral angulation; the third from the anterior has 4 trace in a longitudinal fulness above the middle of the side ; the last, the same, below the middle of the side. The margins of the extremities are well flared. The neural canal is a little compressed and deeply excavated in the centrum. The surface of the centrum is only rugose at the base of the diapophysis. The general form viewed laterally is subquadrate, the anterior vertebra a little deeper than long, the posterior a litile longer than deep. Measurements: MM.

Asin H. fouiket, the neural spines have a small antero-posterior diam- eter, and the zygopophyses are little developed. The anterior are sub- acuminate and more or less joined together. As the neural spine is very oblique, the posterior zygapophyses are above a point behind the articular extremity of the centrum. This species differs at once from the ZH. tripos, H. foulket and H. minor in the opisthocoelian vertebr, resembling in this respect the H. occi- dentalis (Thespesius, Leidy). The latter differs from HZ. cavatus in the development of the chevron articulation equally on both adjacent centra, instead of on the posterior extremity only. In H. foulket and IL. tripas * this double junction of chevrons extends to the extremity of the caudal series, adding another important ground of difference between them and the H. cavatus. The single caudal vertebra of H. ocetdentalis known, is like that of the former species in this respect, but there is no certainty that the structure continues the same throughout the caudal series, and that the distal vertebrae may not be like those of JZ. cavatus in this re- ji Cope.] 52 [March 3, spect. It, however, further differs in the relatively more compressed or oval centrum, and much greater size. From /. minor the present reptile differs in the opisthocoelian vertebrae, the known caudals of the former having plane articular surfaces, and in the much larger size. It is not possible to compare similar parts of this species and the Ornithotarsus immanis, Cope, but the larger size and much lower stratigraphic horizon of the latter renders their identity very doubtful. Should the genus Thespesius of Leidy turn out to be well eatablished, the present species will enter it. I am not, however, entirely satisfied that the difference in the form of the articular faces of the caudal vertebra is such as indicates generic difference. It was on this ground that I referred this form to Hadrosaurus (in Synopsis Extinct Batr. Rept. N. Amer., p. 98), and not from misapprehension of Leidy’s definition of it, as the latter supposes (Proceed. Aca. Nat. Sci., 1870, p. 67). The rather slight material above described is fortunately so character- istic as to enable us to establish satisfactorily the existence of another monster of the remarkable group of the Dinosauria; beings, whose ap- pearance and structure have rivalled the strangest creations of the imagination, and shown again what every other page of the book of nature teaches, that reality is stranger than fiction.

The pertinence of this genus to the Elopide is indicated in various ways. The general form is that of Hlops and Megalops, and the normal and supernumerary ribs are quite as in the former. The interneural spines extending from the head to the dorsal fin, are quite like those of the same genus. It differs from both in the posterior position of dorsal fin, and relatively numerous abdominal vertebrae.

The body is seen in profile, but the head has been pressed from above, and the view is therefore oblique. i The general form is elongate. The pectoral fins are inserted at the pectoral plane, and are of moderate length. The ventrals are short and small. It is uncertain whether they reach the anal, as the anterior part of that fin is destroyed. rom the small number of interhemal spines, the anal has probably hada short basis. Caudal lobes narrow. A strong horizontal interneural spine. The anterior interneurals are like those of Megalops, slender, gently curved rods, apparently, but not really contin- uous with the neural spines in some places. The dorsal fin laid back- wards extends to the emargination of the caudal. The vertebre near the head are not altered. There appears to have been a laminiform crest on the head, but the bones thus described may be those of the opposite side of the cranium. The muzzle appears to be contracted and projecting beyond the mouth. Three narrow obtuse teeth appear on the edge of the premaxillary bone. Dentary bone, stout.

The appearance is not unlike that of Osteoglosswm, but the structure of the scales distinguishes it. The great development of the swd- and postorbital bones, and small size of the preorbital, distinguish it as allied to the Characins. Its dentition and general form approach the genus Anacyrius Mill. but it is at the same time distinguished by the lack of maxillary teeth. In addition, it appears to lack the anterior inter- neural spines found in so many Characin and Clupeoid genera, and in families allied to them. They are at least not apparent on the faces of two fractures across the vertebral column. Three vertebrae are exposed throughout their length. They are longer than deep, and exhibit the two lateral grooves common to so many Teleosts. The only scales pre- served are those above the pectoral fins, with but few above the vertebral column. None of these present traces of the lateral line. The clavicle makes a right angle with its inferior limb, and with the coracoid, and is produced backwards at the base of the pectoral fin. The epéclavicle and post-temporal are wide bones. The operculum is developed upwards to the epiotic, and the interoperculum is present. A fragmént represents the suboperculwm, which was probaly a narrow bone. The coracold was a broad vertical lamina, extending horizontally forwards to below the pre- operculum, ANADOPOGON TENUIDENS, Cope. Orbit round, its diameter entering the length of the head five times, and a little exceeding that of the muzzle and. closed under jaw. The pro- file is gently descending and perhaps slightly concave ; the symphysis mandibuli is very stout and presents an angle outwards; the inferior margin of the dentary is slightly convex. The maxillary bone is slender. The suborbital bones together form a shield deeper than wide; with the postorbitals they reach the preoperculum. The head increases rapidly in depth. The scales are large, and extended below the operculum on the sides of the coracoid region. They have smooth margins, and are every- where quite thin. The surface is glistening, and in some scales exhibits under the microscope delicate parallel lines which separate short concave lines. The middle of the scale is marked with obtuse tubercular radii, or small or minute tubercles. Measurements. M.

It shows, moreover, that there is a nor- mal intersection of a polar (N. E.) current off the coast of Florida, with an equatorial (S. W.) current from the Bahama Islands, and a similar in- tersection of a south-easterly and south-westerly equatorial current, (the latter having been refrigerated by the Sierra Nevada,) near the common boundary line of Nebraska and Kansas. The former of these intersec- tions is analogous to the one referred to by Mr. Scott, as indicative of an approaching gale in the British Islands, and suggests an obvious explana- tion of the gulf stream cyclones, as well as of the cyclonic winds in Western Europe; the latter helps to account for a considerable propor- tion of our land storms. The comparisun of these currents and intersections with Blodget’s hyetal charts is very instructive, and I feel little hesitation in predicting that a more thorough acquaintance with the winds of Alaska and British America, will develop another anti-cyclonic system, referable to a differ- ent centre of disturbance, with intersecting normals near the northern boundary line between the polar and equatorial prevailing winds, and perhaps in the valley of the Saskatchewan, which has been specially de- signated by Professor Henry as a storm-breeding district. Chase. | 68 [April 7, RESEMBLANCE oF Atmospheric, Magnetic and Oceanic Currents. By Pursy EARLE CHASE. (Read before the American Philosophical Society, April 7, 1871.) My belief that terrestial magnetism is dependent solely upon fluid cur- rents, electrified by convection and by the condensation of vapor, led me to look for some confirmation of my views in the results of my recent discussions of the winds of the United States. My attention was first drawn to the resemblance between the looped isogonic lines in the eastern equatorial portion of the Pacific Ocean, and the anti-cyclonic course of the winds in the Gulf States. The undoubted rapidity of macnetic action, a rapidity analogous to, if not identical with, that of luminiferous vibra- tions, renders it probable that the flexure of the isogonic lines, at any given point, may be determined by the resultant of all the forces acting at that point, and that the equatorial loops are, therefore, expressions of equatorial disturbance. Tf the same disturbance is communicated to the more sl uggish air, its culmination may naturally be sought at some point northward and east- ward, because of the well-known laws of current deflection. The prin- cipal thermal contrasts which contribute to the establishment of currents, are: 1st, land and water; 2d, polar and equatorial; 3d, heat and cold at isabnormal centres. It seems reasonable te suppose that these triple con- trasts should be so mutually related, that there may be some system of rectangular codrdinate planes which would present each of them as a maximum. A great circle cutting the equator on the meridians of 100° W. and 80° £., and passing through the geographic centre of the land hemisphere, follows the general trend of the American coast from Florida to New- foundland, skirts the equatorial isogonic and the Florida atmospheric loops, finds the western limit of our anti-cyclonic system of winds at a point about midway between the magnetic pole and the equator, and crosses the equator on the meridians and near the centres of greatest Horizontal Force. A co-ordinate great circle following the meridians of 10° W. and 170° E., intersects the magnetic equator of minimum inten- sity near its greatest northern and southern elongations. The third co-ordinate great circle corresponds very nearly with the dividing plane between the land and water hemispheres. The principal north pole of declination and the Asiatic equatorial intersection of the line of no varia- tion, are on the meridians first named, which traverse the intersections of the first and third co-ordinate circles. A great circle intersecting the second co-ordinate on the equator, and passing near the North American pole of declination, would cut the first of these meridians (100° W.) at an angular distance from the pole analogous to that of the Florida wind loop from the equator, traversing the principal isogonic loops in such manner as to exhibit the magnetic symmetry of the entire globe to the best advantage. No other system of rectangular co-ordinate planes would meet with so little Jand interruption, or would divide the globe jnto hemispheres with so great current-producing contrasts. cal —— — C 1871.] 69 [Chase. An observer, therefore, near the centre of the land hemisphere, would find, at the four cardinal points of his true horizon, magnetic, thermal and geographic positions of peculiar importance, and indicative of inter- esting mutual relations. The recognition of such relations gives a new interest to the often noticed resemblance between the isoclinal and iso- thermal lines, the analogy which I have myself pointed out between the iso- gonic and cotidal lines, the parallelism of the boundary lines and of the axis of the westerly isogonic belt with the boundaries of the correspond- ing annual isabnormal belt, the isogonic curvatures in or about regions of isabnormal heat or cold, ‘se different angular relations of the isogonic lines to the customary paths of hurricanes and storms, and the approxi- mate perpendicularity of direction and ~— of curvature between the westerly wind belt and the isogons. - All of these features, which may be satisfactorily explained by the general indie on which storm laws are based, furnish cumulative, if not irresistible, evidence of the de- pendence of magnetic currents upon the same laws of gravitation, which tend to restore the equilibrium of air and sea, after tid al or thermal dis- turbances. The evidenceis sustained not only in the general distribution of the magnetic lines, but also in their particular details, the course of the isogonic lines, at every point, being an evident resultant of the com- bined equilibrating tendencies between land and water, and between centres of normal and isabnormal heat and cold. The ocean currents corroborate the gravitation theory of magnet- ism, perhaps even more strongly than the wind belt. A physical atlas like Petermann’s, which marks the most rapid portions of the several cur- rents with the deepest tints, shows their relation to the magnetic and coast lines very satisfactorily. A comparison of the more minute details exhibits additional interesting evidence that the original impulse of all terrestial currents, atmospheric, magnetic and oceanic, is given by lumin- ous, thermal or tidal disturbances, that the currents are maintained by gravity in its continual tendencies to restore the continually dis- turbed equilibrium, that the magnetic currents are least, while the ocean currents are most interrupted and modified by land contours, that each of the more sluggish currents exerts a secondary modifying influence on the more rapid, that extraordinary variations in thermal or luminous undu- lations, whether originating at the sun or at the earth, produce ‘‘mag- netie storms,’’ and that, whatever theory may be adopted as to the mode in which the solar undulations are transmitted, there is no philosophical necessity for the hypothesis of any cosmical origin or disturbance of ter- restrial magnetism other than variations in the amount of light and heat received and in the directions of gravitating tidal and equilibrating lines. * * It is so difficult to make the necessary allowances for the distortions of the ordinary magnetic the it | would recommend any one, who may desire to make the comparisons which | have g , to trace the lines on aglobe. A slate globe is especially satisfactory. The data for my own comparisons were taken from the lines of equal magnetic tion and of equal horizon force for 186 24 edition of the ** Admir by Manual for ascertaining and applying the de tions of a compass, caused by the iron in a ship.” Walker’s ‘* Terrestial and Cozmi¢al Magnetis Cottin’s “ Winds of the Northern Hemisphe¢ Dove’s “Isothermal and Isabnormal chart “ Petermann’s and Johnston’s Physical Atlase In order to judge of the resultant influences of the normal and isabnormal thermal disturbances, it will be well to mark the « es of isabnormal heat and cold,as well as the points of greatest average heat and cold. 70 Dutton. ] ‘ [April 7, Mr. Walker, in his Adams Prize Essay for 1865, p. 268, says: ‘it is worthy of remark that the portion of the year when the magnetic force is the greatest, and the direction of the needle most vertical in both hemis- pheres, coincides with that at which the earth is nearest to the sun and moves with the greatest velocity in its orbit. This fact furnishes another argument against the theory that these effects are due to temperature, as in that case they ought to occur at opposite periods of the year in the two hemispheres, whereas in fact they occur at the same period in both.’’ The writer was doubtless misled by the annual variations in declination and horizontal force, which are evidently dependent upon the relative tem- perature of the northern and southern hemispheres. But if all the magnetic effects are primarily due to thermal and gravitating motion, it is evident that the tota/ magnetic foree must depend upon the total cur- rent producing energy of the sun, which is, of course, a maximum when “the earth is nearest the sun, and moves with the greatest velocity in its orbit.” The argument which was considered conclusive against the the- ory, is, therefore, wholly in its favor. Tue cAusES oF Regional Elevations and Subsidences, by Lirur. C. E. Duron. (Read before the American Philosophical Society, April 7, 1871.) Lieut. C. E. Dutton, desired to submit certain views, which he had been led to entertain, respecting the causes of regional elevations and subsidences. He was unacquainted with any views on this subject in the writings of geologists, which seemed to be satisfactory. In reflecting upon the nature of metamorphic rocks, and the probable changes which they had undergone, he thought that the facts brought to light by the re- searches of Bischoff, Daubrée, Sorby, Sterry-Hunt and others in that field, might contain, also, a solution of the unexplained problem of ele- vations and subsidences. It is now a generally accepted opinion among writers upon chemical geology, that metamorphic rocks have reached their present, condition, through the combined agencies of heat, pressure, and water, acting upon sedimentary strata; that sulphur, carbonic acid and yolatile chlorides and fluorides have played highly important parts under similar conditions, and that soluble earths and metallic salts and vapors have had no inconsiderable influence upon the totality of changes, That water especially, under the influence of a moderately high temperature and great pressure, is capable of changing in a wonderful manner the structure and arrangement of rocky materials of all kinds, has been abun- dantly shown by innumerable synthetical experiments, a great number of which have been summed up by Daubrée in an able memoir on the sub- ject to the French Academy. He has also shown that minerals, which, — 1871. J i] [ Dutton. under ordinary temperatures to which water is subjected, are in no re- spect changed, may be completely altered by water confined in strong s. Silicates, aluminates and calcareous matters in the amorphous condition, may not only be made crystalline, vessels and heated to dull redne but their degrees of hydration may also be permanently altered; and he also mentions the production of anthracite by a simi ir process, from wood. Indeed, the changes both of structure and chemical constitution, which may be produced in this manner, are very great, and extend, in all proba- bility, to nearly the whole range of mineral matters found in the rocks. Now, if as is generally believed and accepted, these are the changes in progress, while rocks are undergoing metamorphism, then, in all proba- bility, the rocks are undergoing at the same time «@ change tn their specific gravity. Itis highly probable, if water is the chief reagent, and if it constitutes a change both chemical and physical, that the specific gravity of the mass, into which it enters, is not the same as it was before such a change took place. Butif we admit this, then we have also admitted that the volume of those rocks has either increased or diminished. If we assume it to have increased, there must take place an expansion, and such an expansion must necessarily be upward. For, beginning at the lowest level, at which any such change may be assumed to supervene, the total weight of the superincumbent mass is the same as it was before, and hence there would be no change at that level. Nor could there be lateral expansion of any importance; all expansion would of necessity be verti- cally upwards. On the other hand, a decrease of volume would occasion a subsidence for converse reasons. If we were to assume a change in the specific gravity of 1000 fect of rock, to the extent of five per cent., we could account for a change of level of 50 feet, and a series of rocks as thick as the carboniferous in this State, would, with an equal amount of change, give an alteration of level equal to the average attitude of the North American Continent above the ocean. It is, of course, impossible to conjecture the depth to which metamorphic action may extend, though it is undoubtedly very great; at least eight or ten miles, and there might be no great improbability in supposing such changes to take place through a large portion of that depth at the same time. That the rocks far down below the surface take up under the influence of great pressure, aided no doubt by heat, large quantities of water, car- bonic acid, sulphydric acid, and perhaps other electro-negative agents, is manifest inthe materials issuing from voleanoes and from thermal springs. Water and gaseous acids issue in such enormous quantities from volea- noes, as to constitute a large fraction of the entire mass delivered, indi- eating that the solid materials have become super-saturated with them, and the association is resolved as soon as they reach the surface of the earth, and are relieved of the pressure to which they have been subjected. The overflow of volcanoes would, it is suggested, be susceptible of a similar explanation. Let us suppose a stratum ortwo, situated afew miles 79 Dutton, | e [April 7, 1871. below the surface, became softened or lightened by the combined agencies described, so as to be specifically lighter than the average mass of over- laying rock. Ifa vent or fissure could be found, such a plastic mass would inevitably follow the laws of the equilibrium of fluids, and would not only rise up into the chasm, but overflow. Putting the problem into another form, the heavier over-lying mass would sink into the lighter semi-fluid beneath, and drive it upwards. It is a well known fact, that the lavas are all of small specific gravity. Indeed, were it otherwise, Lieut. Dutton thought that the overflow of a lofty voleano like AStna or Mauna Loa, would be impossible; for a column of dense material of such a height, exerting its pressure upon its subterranean reservoir, would raise the overlying strata, instead of rising above them. But, in truth, the superior strata are doubtless heavier, and exert a greater pressure upon the reservoir than the lava itself. Ina similar manner Lieut. Dutton sought to explain the intrusion of traps, trachytes and basalts. These rocks were probably lighter than those which originally overlaid them, and forced their way through weak places to the surface. The traps, basalts and porphyries,—at least such porphyries as may be called intrusive—though they are unquestionably altered sediments, are for the most part amorphous, and not crystalline. They were evidently altered at a comparatively low temperature, and at no very great depth. They do not appear to affect the strata into which they are intruded, and withal, are less highly metamorphic than gneiss or marble. Water seems to have been the chief agent in their transforma- tion, and they may have been forced upward in asoft condition, and upon being relieved of the pressure, parted with the greater portion of this water, The traps and basalts also exhibit many planes of cleavage, with very perceptible interstices, and these interstices would seem to be much wider than could be accounted for by the contraction of cooling. He stated that he had often noted this fact, and was decidedly of the opinion that the contraction of these rocks by loss of heat, could by no means account for the entire width of such plans of cleavage, and be- lieved that it was in great part due to the loss of water, which had once rendered them plastic. If these views be correct, then we ought to expect that voleanic regions will be confined to those areas which have recently been regions of marked elevation. And we find this to be the case. In America, the whole extent of the Rocky Mountains and of the Andes, so far as known, was covered by the ocean at the beginning of the Tertiary period. The elevation of the Rocky Mountains was probably earlier than that of the Andes, and sooner completed. Hence, while the former was the scene of an unparal- leled amount of volcanic action during the Pliocene and Miocene, and is now nearly, or quite, quiescent, except in Southern Mexico, the Andes still abound in active volcanoes. The East Indian voleanice regions are all of Tertiary formation, as are those of the Mediterranean and the Auvergne. April 7, 1871.] 13 [Cope. PRELIMINARY REPORT ON THE VERTEBRATA DISCOVERED IN THE PORT KENNEDY BONE CAVE. ‘ By Pror. E. D. Copz. (Read before the American Philosophical Society April 7, 1871.) My friend, Charles M. Wheatley, has already given an account of the discovery of a fissure in the Potsdam limestone of Chester Co., Pennsyl- vania, containing the remains of numerous animals and plants of the Postpliocene period (see Amer. Jour. Sci. Arts, 1871, April). Dr. Quick, of Phanixville, having brought to his notice mastodon remains exposed in quarrying the limestone near Port Kennedy, he visited the spot, and determined the existence of the fissure and its contents. In the article in question he describes it as situated near the line of junction of the Triassic red sandstone. Its depth is nearly fifty feet, and the greatest width thirty ; at the summit or surface of the limestone, its width is twenty feet. It is filled to a depth of forty feet with the debris of the neighboring Triassic strata, of a red color; below this point is a bed of tough “black clay eighteen inches in thickness, filled with leaves, stems, and seed vessels of post-tertiary plants. Scattered through all this mass of vegetable remains, and also in a red tough clay underneath for six to eight inches in depth, are found the fossils noticed in this paper.” Mr. Wheatley furnishes a list of the species we had identified up to the time of writing, viz. ; twenty-seven vertebrata, ten coleoptera, and ten plants. These numbers have been considerably increased up to the present time, and I look to a much fuller and more complete exposition of the Postpliocene vertebrate fauna, in consequence of a more thorough examination of the remaining part of the fissure, by my friend, C. M. Wheatley. As regards the position of the remains, the article above quoted, pro- ceeds to state that “the remains of Mylodon, Ursus, and Tapirus have been mostly obtained from the tough red clay directly under the plant bed, but the remains of rodents, snakes, tortoises, plants, and insects, are entirely confined to the plant bed. Neither the bones nor the teeth are rolled or water worn, but all are sharp and well defined.’ The appear- ance of the specimens corroborates the above statements. I would add some exceptions. Thus two of the specimens referred to Arvicola sig- modus came from the red bed, and one from the black; one Megalonyx wheatleyt, came from the black bed, the others from the red. Milk teeth of Mastodon occur in the red bed also. General remarks are deferred to the close of the report. MercGatonyx, Jefferson. The remains of species of this genus found in the fissure are more abundant and striking than those of any other. At least fourteen in- dividuals are represented by the bones and teeth obtained. These belong probably to five species, as described below, four of them different from A. P. S.—-VOL. XII-—J Cope.) ts [April 7, those hitherto known, three of them of a size equal to that of the I. jeffersonit, the others smaller. These species are only certainly distin- guishable at present by the teeth, as the other bones are very similar to those of other species, so far as preserved. The teeth consist of eighteen canine, and nineteen molar teeth, whose characters are discussed below. The bones are chiefly those of the feet, with portions of long bones, and numerous vertebra. Cranial bones are in most instances destroyed, for though several complete crania were ex- humed, the exposure to frosts and thaws with snow and rain, as they laid in the piles of material, disintegrated them. Of limb bones there are the extremity of a large tibia with cotylus for astragalus, several extrem- ities of fibula, and some broken heads of femora. Of the bones of the fore limb there are three unciforms, two magnums, and fifteen metacarpals with numerous phalanges. The bones of the hind limb include three astragali, seven cubiods, six scaphoids, and five incomplete metatarsals. The phalanges of both fore and hind feet, which much resemble each other, number thirty-two, of which nine are ungueal, Of vertebree, no cervicals have been found, except an axis without neural arch. Caudals are most numerous ; some of the vertebra have codssified epiphyses, others not, indicating various ages. I have counted twelve individuals from the teeth, but it is quite possible that there are others represented by some of the bones. The canine (molar) teeth present a remarkable variety of forms. As is known, the section of the crown is oval, on one side concave with a more or less prominent swelling interrupting it. The differences are seen in the development and position of the broad rib of which the swelling is a section, in the curvature of the shaft, and greater or less obliquity of the grinding surface. There are three types of form among them as follows : ist. The shaft curved, the triturating surface oblique, the internal longitudinal rib prominent, nearer one end of the crown than the other, dentine of inner side thickened anteriorly ; two specimens. 2d. Shaft nearly straight, triturating surface transverse (in its long direction); rib of inner face median, prominent ; dentine of inner side uniformly thin. 8d. As in the last, but the shaft more compressed, therefore the section narrower, the inner bulging rib being very low and insignificant. The first of these represents a species distinct from those of the other series; one nearer the W. jeffersonii, and of large size. In studying the present genus I have been under many obligations to Dr. Leidy’s Memoir on the Extinct Sloth tribe of North America, pub- lished by the Smithonian Institute in 1855. In it the species Megalonyx jefersonit is established for the first time on a solid foundation, and the characters, especially of the dentition, clearly pointed out. M2EGALONYX LOXODON, Cope, species nova. The two teeth of the first type may, perhaps, be superior ones; their curvature accounts for the obliquity of the grinding face in the long me 1871,] [Cope. direction, This curvature is seen in teeth of WV. jeffersonii (See Leidy’s Memoir on Extinct Sloth tribe, Pl. VI., figs. 4-6), which do not appear to be straight in the maxillary bone at least, at any time. These teeth differ from those of I. jeffersondi in having the posterior margin thinned ut, while the anterior is thickened by the near aproximation of the interior rib. In the larger of the two the posterior margin is slightly in- curved, the exterior convexity thus produced opposing that of the anterior face and inner rib, as one short side of a romboid does that opposite to it. The section of the smaller differs in the shortness of this intero-external face, and is thus rounded subtriangularly and antero-internally, as de- scribed by Leidy in the IZ jeffersondi, and thus different from that seen in the W. wheatleyt. The external face has an open longitudinal con- cavity, The triturating surface in both teeth is a longitudinal groove ; in the larger, the inner margin is highest anteriorly, the outer highest posteriorly. These teeth I suppose to represent a species different from the J/. wheatleyi, and perhaps from the M. jeffersonti also, as none of the sections given by Leidy (1. c. Pl. XVI), approach their form. The nearest is his fig. 8, where the section of the bulge is not quite central. MEGALONYX WHEATLEYI, Cope. Species nova. Represented especially by fourteen canine and sixteen molar teeth, but probably also by the greater part of the bones above mentioned. The former are referable to eight individuals, to which perhaps four others should be added. The characters of the species are chiefly visible in the molar teeth, which in the maxillary bone are acutely trigonal instead of triangular ovate as in the MW. jefersont?; and in the dentary bone, transversely, sometimes narrowly, parallelogrammic, frequently narrower internally than externally. In the W. jeffersonii the latter are almost as broad as long, of equal width, and with the inner or outer margin slightly oblique.” In the cantne-molars before mentioned of the second and third types, Wwe have but little or no curvature of the shaft, no longitudinal grooving of the outer face, the outer dentinal wall uniformly higher on the tri- turating surface than the inner, and the long diameter of this face but little oblique to the transverse plane of the shaft. As both superior and inferior molars corresponding in size, color, and number to these teeth have been found, I suppose the latter to have been derived from both Jaws, The differences in these teeth are to be seen in the different degrees of development of the dentine layer, and of the bulge on the inner face, and of the degree of compression of the shaft. Five of the best preserved ex- hibit the thickness of the external layer continued round the extremities of the grinding surface, and then rather abruptly contracting wedge like, into the thin layer of the interior face. In two other teeth this con- traction takes place at the external curves, and is less in degree, the inner April 7, ASE iu, ) Lar f 1871.] i7 [Cope. layer being more uniform. In two teeth the dentine of the bulge of the inner face is very nearly as thick as that of the outer (F. 4). As regards the form, in the last mentioned tooth the bulge is well developed (as in Leidy’s Pl. XVI. fig. 1), and the shaft is not compressed. In the two previously mentioned, the shaft is short and the bulge very low and bounded by two shallow grooves; in one (F. 6) (which is accompanied by the posterior molars), it has a shallow median groove. In the five canine molars first named we have every degree of compression. In one (F. 3) the shaft is stout, and the bulge larger than in any other, about as in Leidy’s Pl. XVI. fig. 2; in a second (F. 5) the shaft is similar, with low bulge, like fig. 7. 1.c. In the third (#. 7) from a large individual, there is more compression, and the bulge is very low ; the last two are similar, but sinaller; they belong apparently to opposite sides of the same animal (F.8). These are like the tooth figured and described by Dr. Leidy as that of Megalonyx dissimilis. T am inclined to refer the teeth of these types to one species, a view confirmed by a study of the molars. They are all stained yellowish or light rust color except one, which is black, and which is associated with three posterior molars of similar color and corresponding size. The re- maining posterior molars are of the color of the other canine molars, and no doubt belong to the same individuals in part, but none can be associ- ated with the same certainty as the black specimens. On the light colored posterior molars I propose to establish the Meyalonyx wheatley?, since I should scarcely distinguish it from M. jeffersonti, or M. dissimilis by the canine-molars alone. There can be-no question that the forms of these teeth, characteristic of the two supposed species, graduate into each other ; the characters derived from the development of the interior enamel plate, may be distinctive, but in that case there is at least one other undescribed species in the series I have explained above. I. dissimilis it appears to me must repose on the posterior upper molar, which Leidy shows to be transversly oval and not triangularin section. That tooth is as triangular in M. wheatleyi as in M. jeffersonit. From the preceding, it is probable that the most allied species of Megalonyx, cannot be exactly defined by the characters of their canine molar teeth, though, as in many species of Mammalia, they may be in- dicated by the extreme forms of those teeth, the range of variation over- lapping. The supertor-molars (1a) belong to at least three (perhaps four) in- dividuals. They are nearly straight trilateral prisms, so worn that the inner anterior angle is the most elevated. The anterior dentinal plane is slightly convex, the posterior concave to a less degree. The exterior angle is much less obtuse than in WM. jeffersonii, that enclosed by the dentine being prolonged and very narrow. There is a notable difference between the two posterior molars of the superior series, preserved. One belongs to the individual stained black. Both are slightly bowed pos- teriorly, and both have a subtriangular section, the apex directed inwards. i Cope.] i8 [April 7, In the light colored specimen the outer face is wide and nearly plane, the anterior very slightly convex, and the posterior concave, making an open longitudinal groove ; the external angle is obtuse. In the black speci- men the inner face is narrower, the anterior more distinctly convex, and the posterior convex also, rounding off to the more obtuse external angle. Both these teeth are worn obliquely as in A. jeffersonit. The wearing of the median molars is transverse to the axis of the shaft anteriorly, oblique to it or descending inwards, posteriorly. The wearing in the long axis of the jaw bone, is obliquely forwards on the posterior dentinal wall, and divided on the anterior, one half sloping forwards and the other backwards, the slopes separated by a sharp ridge of the dentine. A. single tooth, which by its form is excluded from a place in the man- dible, and by the character of the wearing of its crown, can be none other than the second molar, or first of the regular series. Its form is very different from that of the same tooth in I. jeffersonit, but is appropriate to the modification described below. as characteristic of the inferior molars of MW. wheatley?. There is no anterior wear on the anterior den- tinal plate, indicating the absence of any tooth anterior to it in the infe- rior jaw ; this plate is much higher than the posterior, which has two worn surfaces, the anterior horizontal, the posterior oblique. The middle of the crown is concave, and the concavity is carried across the dentine of one end. ‘The tooth is in section a transverse parallelogram with the outer short side oblique, instead of parallel to the inner. Anterior face slightly concave, posterior slightly convex. The characters of the inferior molars are established by three posterior in place in the fragments of jaw held together by the matrix of red sand and clay. That they might be the superior series of another species is suggested by the subtriangular outline of two of them, and the jawis so fragmentary that it is not sufficient to decide the case. The following points, however, are conclusive. If they were superior, the terminal teeth must be either the second or fifth molars, according to the relation to front or back in which they are viewed. ‘That neither can occupy this place is proven by the following description: The anterior is a rather narrow transverse parallelogram, with the sides and angles rounded. The posterior dentinal plate is worn trans- versely, the opposite one is oblique, descending to one side. The form is worn obliquely away from the centre of the crown, the latter is plane. The next tooth is a parallelogram narrowed towards one end, which is rounded obliquely to the other sides; it is narrower than the last, and the dentinal plates are worn in exactly the same way. The last tooth is much wider than the others, and has a subtriangular outline, the narrow end very wide and obtuse, and on the same side as the narrowed end of the one in front of it. The outline is worn in the same manner, except that the angle at one end of the base of the triangle is, perhaps, more elevated. (1.) Neither of the extremital teeth have the oblique face of the pos- ae wy 1871.] i9 [Cope. terior one of the known species of Megalcnya, nor the reduced size, so that it remains to ascertain whether either of them is the first superior molar. (2.) The larger is evidently notso, because it has an obliquely- worn distal face, indicating the existence of another tooth beyond it in the opposite jaw. (8.) The opposite one is not the anterior molar, be- cause (a) its anterior dentinal face is worn horizontally, not obliquely backward, indicating an overlapping tooth ; (b) because the oblique wear of the dentine would, on the supposition that it is the first, be thrown on the posterior instead of the anterior faces of the other molars ; (c) and because its form is narrower than the other teeth, instead of wider as in other species. Confirmatory of this conclusion is the fact that no palate can be dis- covered among the fragments where it should be, were these teeth max- illaries. The question as to the relation of ends is settled by the fact that the plane of the crowns rises to the narrower, which would thus be anterior. Also the large tooth has the oblique surface for the last supe- rior molar, which the anterior has not. The fragments of the jaw indi- cate the same thing, rising (towards the coronoid process) at the large tooth and falling at the narrower. The latter, then, for the above rea- sons, I assume to be the anterior. M.

Three of these are evidently anterior or second inferior molars, two of the left, side and one of the right. Their section is suboval, and all the details, size, &c., areas above described. Two others are like the second (or third) inferior molars. One of these is peculiar in being a little concave on the anterior face, the inner extremity very oblique, the other is more oval. = The question as to the specific relations of these inferior molars may be stated as follows. Their large size precludes the probability of their be- longing to either WM. tortulusor M. sphenodon. They appear to belong to one species, without doubt. The superior molars also belong to one species, and as no other species is represented in any thing like the same abundance, it is reasonable to suppose that these, with the most abundant of canine molars, belong to the same form of Megalonyx. The canine molars differ from those of JZ. lowodon, and the posterior upper molars from those of M. dissimilis. The disproportion between the sizes of the second and last inferior molars, with the narrow oval and triangu- Cope.] 80 [April 7, lar forms of the same, separates the animal from the W. jeffersondi. The only known molar of M. valédus, Leidy, is like nothing found in the present species, and M. rodens and M. meridionalis each have their peculiar features. I therefore call the present animal J/. wheatleyt. 4 Another molar, perhaps the third inferior of the three, is larger, and appears to belong to another individual; it is a little wider inwardly, and resembles Leidy’s fig. 13 of Pl. XVI., except in its narrower angle and perfect symmetry. It may belong to Jf. wheatleyi, but the outer angle is regularly rounded; it may be M. sphenodon. Vt differs from those of M. jeffersonit as the MM. wheatley?, in the greater extension in a transyerse direction, and in the concavity of one of the long sides. The enclosed area of osteodentine is in section a frustrum of a narrow triangle, instead of rounded parallelogrammice as in M. jeffersonit. Measurements of teeth. M.

This pro- cess is short and conic, and is a continuation of a projection of the cen- trum, which is notched on each side above, at its anterior limit, for the annular ligament.

A caudal, with co- ossified epiphyses, has subround articular extremities, and is remarkable for the extent of the chevron articulation of both ends of the inferior aspect.

The Engineers and Surveyors’ Transit as at first constructed commonly termed a “flat centre,’’ or “Railroad Transit,’ although superior to the English Theodolite which it superseded, yet in practice has been found defective in the following mechanical details. ist. The upper or vernier plate, resting and turning upon the under or graduated limb, was accompanied by so much friction, caused by the large extent of the rubbing surfaces, that in turning the vernier plate around the limb, the whole instrument would sometimes be moved upon the lower spindle. 2d, The oil that was necessarily used to lubricate the plates, would be- come so congealed in cold weather that the plates would not move at all, and old Railroad Engineers will readily recall the thawing out of their in- struments over large fires, at every fall of the thermometer, before they could be used. 3d. The spindle upon which the entire instrument turns, being detached from the instrument, thus violating one of the standard rules, that by long experience in this country and Europe, has been found necessary in the con- struction of any instrument with any pretensions to accuracy, NAV AMR C) instrument having a graduated plate and levels should be so constructed that both of the centres upon which the instrument turns should be always covered and not detachable from the main plates.”’ To prove the utility of this rule, it is only necessary after adjusting the levels of one of this class of Transits so that they will reverse on the top centre, to clamp the two plates together, and turn the instrument on the lower spindle, and the levels will invariably be found out of adjustment, showing conclusively that through some cause, most frequently the settling of flying dust, etc.,, upon the surface and shoulder of the spindle, the spindle is not at right angles to the surfaces of the plates. Ath. The centre around which the graduated limb revolves can only be the thickness of the graduated limb; this centre by reason of its small surface wears after comparatively short use, and does not exactly fit the conical hole in the graduated limb, and two readings of the same object taken without any change inthe position of the instrument have been found to differ by 5/, and from no other cause than this. These various defects have caused this style of instrument to be entirely discarded in city work, and for this another construction is used in which the two main plates do not touch each other, thus obviating the two first evils, viz.: the friction of the two plates rubbing one over the other, and the stiffness of motion of the plates in cold weather. The sockets and spindles apon which the main plates revolve being long and fitting Heller and Brightly.] 1 I 6 [May 5th, one inside of the other, and neither of them being exposed or detached from the instrument, thus remedying the two last causes of error. These two are the only styles of Transit made, and are respectively termed the “short centre Transit’? and the ‘‘long centre Transit.’? The ‘long centre,’’ although the most perfect in its construction, has never been a favorite among Railroad Engineers for the following reasons : ist. The increased size of the centres making it heavier, and this being a very serious objection where an instrument must be carried several miles every day as is frequent in Railroad surveys. 2d. The instrument not being detached from the tripod, except at the base, compelled the Engineer in moving the instrument from one station to another to either carry the entire instrument himself or trust it to his assist- ant, while in the short centre, the instrument lifting off the spindle, the Engineer could take the comparitively light instrument with all the im- portant parts, and leave his assistant to carry the heavier portion of the tripod with its leveling screws, legs, etc. 3d. The removing and replacing of the instrument on the tripod being accomplished by means of a large screw thread, is a very tedious and un- safe method, and if not very carefully performed is liable to injure the instrument. Ath. The extra skill, time, and care required in making the long centre was so much greater than the flat centre, that the price of the instrument was materially increased. Ever since the introduction of the Transit numerous endeavors have been made to reduce the weight of the instrument, but as they have all been conducted on the same principle, 7. ¢., reducing the thickness of the various plates, etc., their only effect was to make the instrument so slight as to be unsteady, their bearing surface so short as to soon wear loose, and the instrument always losing its adjustment. The manufacturers of this instrument have had their attention drawn to the increased strength and steadiness that the employment of the ‘‘transverse section,’’ ‘ rib- bing or bracing,’ imparted to metals; and the amount of metal that could be removed from a solid plate of metal, and its strength and steadi- ness not impaired, but even added to, if only judicious ribbing was re- sorted to. In this improved Transit, which is a long centre, the weight as compared with an ordinary Transit of the same size is reduced one-half, and the instrument is not contracted in any part, but insome parts where increased size would be an advantage, such as the graduated plate, centre, etc., it has been done, but all the plates, etc., are ribbed in such a way as to be stronger than a solid plate, and all metal that did not impart either strength or steadiness has been removed. The Railroad Engineer has in this instrument along centre Transit that can be taken from off the tripod and replaced in a quicker and surer ee 1871.] 117 (Heller and Brightiey. way than the short centre Transit, but unlike the short centre, keeps all the centres covered and not removable from the instrument, and leaves the tripod head and legs with the four levelling screws, ete., to be carried by his assistant. The difference in weight will be appreciated by the Railroad Engineer when we inform him that a plain Transit with all its centres, ete., only weighs about as much as a Surveyor’s Sight Compass, and is more steady and keepsin adjustment better than the ordinary long centre transit, weighing from 25 to 80 pounds. i28) ® The City Engineer has in this instrument all the advantages of the ordinary ‘long centre Transit’? with only half the weight, and an in- crease of steadinsss. There are several defects that are common to all Transits, among which are— 1st. The “tangent or slow motion screw’’ that moves the upper or vernier plate, by use becomes worn and does not fit precisely the thread in the interior of the nut through which it passes. When this occurs the tangent screw can be turned sometimes a complete revolution without moving the vernier plate. This ‘lost motion”? or “back lash”’ of the tangent is one of the worst annoyances of Engineers, aud has been the source of serious errors in the field. Several methods have been devised to overcome this which we will here describe. The nut through which the screw works has been made in two sections to allow of being drawn together when the screw wears. This plan would answer ifthe screw always wore equally in every portion of its length, in other words was a cylinder, but this it never does, and if the nut is tightened so that the lost motion is removed from the thinner portion of the screw, it will move so tightly as to be useless when it comes to the portions that are not worn so thin. There are several methods of drawing the nut together, but they have all the same objections as the above, that is, they are not effective in the entire length, and the nut must be pressed so very hard on the screw as: to make the working of the tangent very tense, especially in cold weather. Another, and the last method has been to apply a long spiral spring be- tween the nut and the head of the screw that acts as the finger piece, thus pressing the nut and the screw from each other, and consequently removing all ‘lost motion’? from the screw. This plan though in theory very good, in practice has been found inoperative, for the following reason: the spiral spring had of necessity to be made long enough, and stiff enough, to act in every portion of the screw’s length, the alternate opening and closing of the spring by use weakened it, and in a short time it failed to remove the ‘‘ back play.’”’ To get rid of this defect of ‘‘lost motion’’ in the tangent screw, opposing or butting screws have been sometimes substituted, but in use they do not give satisfaction, as two hands must be employed in using them, and standing from the edge of the plate, they are liable to be injured by blows, and they are apt, unless very carefully used, to throw the instrument out of level. ———————— en ee aS | | | | << s an Heller and Brightley.] 1 1 8 [May 5th, In this instrument we have an improved tangent screw ; that no matter how much the screw may wear by use, or time, will never get ‘‘lost mo- tion,’”’ but will instantly obey the slightest touch of the hand : this is effected by means of a long cylinder nut, from the interior of which two- thirds of the screw have been removed ; into half the recess thus left in the nut, is nicely fitted a cylindrical ‘‘follower,”’ with the same length of screw thread as the nut; this follower is fitted with a ‘‘key,”’ that pre- vents it turning in the recess, but allows motion in the direction of its length. A strong spiral spring is placed in the remaining half of the recess, between the fixed nut and the movable follower, and the spring has always tension enough to force the follower and fixed thread in con- trary directions, and thus to remove any ‘‘lost motion’? that may occur in the screw. It will be observed, that in this method the spring always remains in a state of rest, instead of clusing and opening, as has been the case in all other applications of springs, and which have been the cause of their failure. Tangent screws that have had as much as 10/ play, have been made to work entirely taut by this method. The mode of attaching the tangent screw to the plates in this instru- ment is entirely new—it is a miniature modification of the ‘‘ Gimbelling”’ of a ship’s compass, and allows the tangent screw, by its free swivel- ling, to be tangent to the plates in every part of its length, and thus never to bind. This tangent screw is also of value for sextants, astro- nomicalinstruments, &c.,where lost motion is detrimental, and a smooth, easy motion is required. In all instruments, the brass cheeks in which the three legs of the tripod play, are fastened to the lower parallel plate by a number of small screws, commonly twelve. When the legs wear in the cheeks, and be- come unsteady, the only method the Engineer has of tightening the legs, is by drawing the cheeks, in which the leg moves, by means of the bolt that passes through the leg; this, of necessity, draws the cheeks out of perpendicularity, and strains the small screws that bind the cheeks to the parallel plate so much, as frequently to loosen them. This source of instrumental error hardly, if ever, occurs to the Engineer, but very good instruments have been condemned as unsteady, when an examination has shown the fault to be the above. ‘This source of error can never occur in this instrument, as the cheeks and the parallel plate are made in one solid piece. But to come to the last and most serious evil. The effective power of the Telescope is impaired by spherical aberration ; that is, the field of view, as seen in the Telescope, is not a perfect plane or flat, but is spherical. To prove this, take an ordinary telescope, and focus it so that an object will be clearly defined at the intersection of the cross hairs or the centre of the field of view, then, by means of the tangent screw, bring the same object to the edge of the field of view and it will be found in 1871.] 119 [Heller and Brightley. every case to be indistinct and not in focus ; onthe contrary, focus it soas to be distinct at the edge, and it will be indistinct when brought to the centre. In some telescopes, however, it is impossible to focus at the outer edge of the field, and objects will be tinged with prisniatic colors, showing that these glasses are affected by chromatic aberration also; sometimes the cause of this defect lies in the object zlass, but in the majority of cases, the lenses composing the eye-piece are in fault. These aberrations affect the working of the telescope in several ways. First, it practically diminishes the size of the object glass, and the view is never so clear and distinct as it ought to be. Second, It is very diffi- cult, and in some cases almost impossible, to adjust the eye-piece to prevent parallax, or “‘travelling”’ of the cross wires, when the eye is shifted from side to side; and practical engineers know what a sharper power of defining, and how much less trying to the eyes a ‘‘soft glass” has—that is, one that has a ‘ flat field.’ This defect has prevented the general use of the Stadia, or Micrometer Wires, as a method of measuring distances without a chain, as the two horizontal hairs that are used, being in diffrent parts of the field of view, can not, in a majority of cases, be focused so as to be devoid of parallax, and the slightest travelling of the wires in this operation will give an erroneous result. The evils of this defect were most forcibly brought to Mr. Heller and the late Wm. J. Young’s notice, when one of their best Transits failed to define in tunnel work, from loss of light, from this cause, and they both endeavored, to within a short time of Mr. Young's death, to remedy it, trying all the known formulas of almost all the opticians in the country, but without any good results. In the Telescope of this instrument these evils are entirely removed, by the employment of a new eye-piece, and advantage has been taken of - the improvements that Optics have made in the last few years, in the curvatures and arrangements of the lenses that compose it; and the test referred to above, of focusing an object in the centre of the field of view, and then bringing the same object to the edge, and it still remain- ing in sharp focus, can be done with this telescope, and the object shows no tinge of prismatic color, showing that both chromatic and spherical aberration have been removed. The advantages of this improved Telescope are : a clear and sharply de- fined field of view ; a field of view so flat that the cross hairs are without parallax in every part of it, and micrometer hairs or Stadia can be used with favorable results. The whole effective power of the object glass being used and none of the light lost, work can be commenced earlier in the morning and contin- ued later in the afternoon than is usual. This, in the winter season, is May Sth, 1871.] 1 20 [Heller and Brightley. no slight matter to the engineer, and lastly, there is no straining of the eyes in sighting. The spider’s web, by reason of its fineness, is the only article hitherto used for cross hairs, yet in use these have been attended with some difti- culties : first, the spider’s web is hygrometric, or is affected by the hu- midity of the atmosphere—when exposed to dampness lengthening, and of course throwing the line of collimation from its true place. This defect is more serious in the Engineer’s Levelling Instrument than in the Transit, instances being known where the line of collimation has altered two or three times in the course of ten hours, by reason of atmospheric changes, and of course any observations taken at those times would be defective ; lastly, the spider’s web being a transparent and not an opaque substance, in some positions it is impossible to see the hairs at all—this is more especially the case when sightiug in the direction of the sun; that is, an easterly course in the forenoon, or westerly in the after- noon. To remedy this defect, platina cross hairs , 755 of an inch in thickness, or as fine as spider’s web, are substituted ; these being opaque, and not transparent, in sighting in the direction of the sun are still visible, and any atmospheric changes, dampness, &c., do not affect them. We believe that we are the first ones,in this country who have drawn wire so thin, and the only ones who have made any practical use of Dr. Wollaston’s experiment. The platina hairs are invaluable in Mining and Tunneling Instruments, that are so constantly exposed to dampness, and being opaque, no reflector to illuminate the cross wires is required. To prevent the stiffness of working of the leveling, tangent and other screws in cold weather, which arises from the congealing of the grease that is used in lubricating them, no oil is used upon the screws of this instrument, but they are lubricated with pure plumbago. By a simple arrangement of the clamps on the axle of our complete Transits, we make them also answer the purpose of a pair of Compass sights, for taking offsets at right angles to the telescope. From the above, it will be seen.that this instrument has the following improvements over the ordinary Transit :—1. A simple, secure and steady method of attaching and detaching from the tripod, being the only long- centre transit made that detaches as easily as a short centre. 2. An im- portant decrease of weight, without decrease of size, and an increase of steadiness. 3. All the working parts of the tangent screw, &c., brought within the plates, making the instrument more compact. 4, An improved tangent screw, telescope, cross hairs and tripod head. 5. A pair of sights for taking offsets; and 6. A new method of lubricating the screws. ‘ May 5th, 1871.] 1 21 (Chase. On the relation of the AURORAS TO GRAVITATING CURRENTS. By Purny EARLE CHASE. (Read before the American Philosophical Society, May 5th, 1871.) Prof. Loomis’s observations of the number of Auroras in each month of 1869 and 1870 (Amer. Jour. of Science, 3d S., i, 309), are specially noteworthy, both because. of the careful accuracy of the observer, and because they are the first published observations which furnish satisfac- tory data for an approximate determination of the laws of auroral dis- tribution. : If the auroras are, as is now generally believed, luminous manifesta- tions of terrestrial magnetism, it seems reasonable to look to them for some additional evidence upon the question of the relation between mag- netic and gravitating currents. Messrs. Baxendell and Bloxam have al- ready pointed out some resemblances between hyetal and magnetic curves, (see Proce. A. P. 8., x, 868) and if analogous resemblances can be traced between hyetal and auroral curves, they will be interesting and suggestive. T have not found the similarity between the annual distribution of rain- falls and of auroras, sufficiently striking to impress any one who has not made a special study of the causes of resemblance and difference. But, as I have repeatedly urged, currents are subject to an increased number of disguising disturbances, in proportion to the sluggishness of their mo- tion, and the time which is consequently required for their formation or change. We may very reasonably look for analogies between the daily and the aunualauroral or magnetic curves, of a character for which we could hope to find no parallel in wind, rain, or ocean-current curves. If we desire, therefore, to find evidence of the joint influence of solar expansion and gravitating equilibrium, we should look where it is most likely to be found, and to the best of the observations which may be sup- posed to be fairly comparable. There are similar variations of solar at- titude, and consequently increasing and diminishing solar foree, in the day and in the year, but the effects of these variations upon the precipita- tion of vapor, are more likely to be shown in their greatest simplicity, by the meaus of observations at different hours of the day than at different seasons of the year. I know of no published observations of this char- acter at New Haven, but there are some extending over a long series of years, at Philadelphia and at Greenwich, the curves at each station indi- cating minima of rainfall at noon and midnight, and maxima in the morning and evening. The difference of longitude between Pihiladeiphia and New Haven being less than 2$°, it is not likely that there is any material difference in the daily rain-curves at the two places. In order to make the curves fairly comparable, both in regard to the times and the magnitudes of deviation, I treated the auroral observations in the same manner as those of rainfall (Proc.. A. P. 8., x, 526). Both in the magnetic and in the hyetal phenomena, the greatest effects accom- pany the greatest atmospheric changes, But in the magnetic disturb- Ae Pe -&— VOL. 211-2 Chase.] 122 [May 5th, 1871 ances the principal maxima occur in the spring of the year and the morning of the day, while the general evaporation is increasing, whereas, in the daily rains at Philadelphia, the principal maximum occurs in the afternoon, when evaporation is diminishing. I have, therefore, compared the midwinter ordinate of the auroral with the noon ordinate of the rain curve, and the midsummer auroral with the midnight hyetal ordinate. The auroral observations and the normal ordinates of the accompanying curves, are given in the following table. I presume no one will doubt that the condensation of vapor, which is represented by the rain curve, is occasioned by the simple operation of gravitation in blending currents of different temperatures, and I see no reason for postulating any different law for the development of electricity and magnetism in the aurora.

In my desire to give proper weight to considerations which favor the hypothesis of normal cyclonic currents, I stated in a recent communica- tion to the Society (March 17, 1871), as one of the admitted facts, ‘that most of the European winds are cyclonic.’’ Further study has satisfied me that this admission is altogether too lib- eral, and that, although a majority of the European winds are cyclonic, the majority is not a large one. The daily weather maps of the French “Bulletin International,’”? and the Quarterly Weather Reports of the British Meteorological Office for 1869, seem to show conclusively that in France and Great Britain, anticyclonic are nearly as frequent as cyclonic currents, and that it is only by a discussion of continuous records that the prevailing cyclonism, such as is indicated in the following table, can be demonstrated. I have deduced the average direction of the winds from the tables in Coffin’s ‘‘ Winds of the Northern Hemisphere.’’ Those marked (C) were computed by Prof. Coffin; the others were obtained by combining, with some regard to weight, the observations which he records for the respective districts.

The inferences of Laplace, that for certain depths, and of Airy, that for all depths, on a globe covered with a sea of uniform depth and without Chase.] 124 (June 16th, 1871. friction, it should be low water under the moon, rest on the assumption that Or is so slight (see Mec. Celeste 327 iv, 887 iv, 342, 2177, Ge., ) that it may be neglected, in order to satisfy equations which would otherwise be impossible of integration. Itis true that the radial codrdinate of the tide wave, is insignificant in comparison with the coédrdinates in lati- tude and longitude, but the cause of that insignificance is not immediate- ly evident, and I can see-no reason for omitting, in tidal discussions, any term which would be important in the discussion of planetary motions. I presume the following postulates will be readily granted. I. If the earth had no axial rotation, the tide would be one of equilib- rium, with high water under the moon. II. If rotation were to commence after the establishment of the equi- librium tide, the tidal ellipsoid would be thrown forward in the direction of rotation. Ill. If the water flowed with such velocity as to be self-sustaimed, the centrifugal balancing the centripetal force, it would be low water under the moon. As neither the first nor the third of these conditions is true, it would seem reasonable to infer that the tidal crest should be at some point inter- mediate between the lunar meridian and the lunar astronomical horizon. The second postulate favors this inference, provided there is any force, other than friction, which would tend to set back the crest of the third postulate. Such forces, itseems to me, exist in the cohesive attraction and incom- pressibility of the water, and the rigidity of the earth, all of which tend to shorten the radius vector and increase the velocity of every particle dm, in two of the quadrants, and to lengthen the radius and diminish the velocity, in the alternate quadrants. These successive increments and de- crements of velocity terminate at the octants, thus tending to produce low water three hours before, and high water three hours after, the moon passes the meridian. Airy (Mo. Notices, R. A. S., April 18, 1866), gives a diagram to show, from the position of the points at which zero horizontal currents become plus or minus currents, that it must be low water under the moon. Tam unable to reconcile his hypotheses, respecting the direction and velocity of the currents, with actual tidal observations, but even if they are cor- rect, I think we should look to the total action of the moon, rather than to the flow of water at particular points. The water falls in the entire quadrants immediately following, and rises throughout the quadrants im- mediately preceding the meridian of high water. Would not this contin- uous action be best sustained if the moon were on the great circle 45°W. of the crest and 45°. of the trough of the tidal wave, as Newton sug- gested in his Principia, B. I., Prop. 66, Cor. 20? e June, 1871.] 1 25 : [Lesley. Note on an Apparent Violation of the Law of Regular Progressive De- bituminisation of the American Coal Beds Coming East. By J. P. Lusiey. (Read before the American Philosophical Society, June, 1871.) In the course of a Geological survey of certain lands in Somerset County, Pennsylvania, it appeared that the beds of coal existing at Ursina held much less volatile matter than was expected. The gas coals of West- moreland County, which come east as far as Connellsville, only thirty miles west of Ursina (see accompanying map), hold between 30. and 40 per cent. of volatile matters. Three analyses show the Ursina coals to have but 17 per cent., while a fourth gives 22 per cent. This puts the Somerset County coals into the sem-bitwminous class. Yet the specimens were taken from gangways, a good many years old, and several hundred feet from the otttcrop, under high hill cover, at a point on the western border of the First Bituminous Coal Basin of Pennsylvania, near the Maryland and Virginia Stateline. More properly we should say that the Ursina coals lie in the second synclinal of the First Basin. For the Negro Mountain Anticlinal comes up from Virginia and splits the First Basin into two in Pennsyl- vania. The mountain dies down at Castleman’s River; but the anti- clinal axis runs on northward. The First Basin is similarly split into two, east of Johnstown, by the Viaduct Anticlinal, which may or may not be an actual prolongation of that of Negro Mountain. To make the situation understood, the following extracts from my re- port to the owners of the property will suffice. The accompanying map shows the Backbone of the Alleghany passing by Altoona. This is the eastern edge of the First Bituminous Coal Basin. The two long parallel mountains between Ursina and Connellsville enclose the Second Bitumin- ous Coal Basin of Pennsylvania. The Third, Fourth, and Fifth lie west of it, and the Sixth occupies the northwest corner of the map ; no moun- tains separating the last four. Figs. 1 and 2 will suffice to show the topographical character of the country, and how the areas of the almost horizontal coal beds have been cut out into patterns, as if with a jig-saw, leaving outcrop edges around all the hillsides, at which gangways enter, and from the mouths of these shutes depend. Figs. 8 and 4 give vertical sections of the coal measures made with Becker’s Barometer ; and Figs. 5 and 6 show longitudinal Vertical sections of the hills. Special surveys like this have more than a commercial value: they reveal, sometimes very unexpectedly, new truths for men of science. It is an advantage to have them placed on record for common use. Too many of the collected facts of science are annually lost for want of pub- lication. The property surveyed in this instance, lies in’ my old tramping and camping ground of 1840, during the fifth year of the State Geologicat * 5 1 26 [June, Resley,] Survey. The report which Mr. James T. Hodge and myself made to Mr. H. D. Rogers, Chief of the Survey, may be found recorded in the Fifth Annual Report (1841), pages 89-92, which I will here recapitulate in the descending order of the beds, for convenience of comparison. The Pittsburgh bed, I, has been eroded from the whole country between the Alleghany Mountain and Chestnut Ridge (at Connellsville and Blairsville) except two hill tops; one, near Salisbury, and the other near Ligonier. It is possible also that a third exception may be discovered in the high hill country south of Johnstown, where a conspicuous bench runs along the hilltops for several miles. Limestone, 20 feet below I, 6 feet thick in the Ligonier Basin. Coal bed H, 50 feet below I, 3 feet thick in the Ligonier Basin ; 1 foot thick in the Salisbury Basin. Coal bed G, 100 feet below H, 1} feet thick in the Salisbury Basin; en- circles the highest hilltops in the Ursina Basin with a conspicyous bench. Fort Hill is not quite high enough to have it. Red Shales between G and F. Coal bed F, 90 feet below G; generally small; but 4 feet thick in the Salisbury Basin. It forms the high terrace of the Fort Hill. Mahoning Sandrock. Coal bed H, <‘ Upper Freeport,’’ 50 feet below F; 2 feet thick, on 2 feet of Limestone (over it Shales with ore-bails) in Ursina Basin ; 3 feet thick, on 5 feet of Limestone in the Salisbnry Basin. Ooal bed D, ‘‘ Lower Freeport,’’ 60 feet below E, 6 feet thick in Ursina Basin ; 4 feet, further north; over 10 feet of Sandstone with ove bails, in two beds, 7 feet asunder, 11 inches in all. This ore ball horison is very extensive north and south of the River. Coal bed C, 20 feet below D, 23 to 4 feet thick. Coal bed B, 30 feet below C on Cox’s Creek, 40 on Laurel Hill Creek (N. Fork), and 60 at Confluence ; 4 feet thick over 8 feet of Limestone on the river; 1} feet thick over 4 feet of Limestone on the North Fork. Twenty feet above B lie 15 feet of Shales, etc., containing ore balls, on Spring Run, below Pinkerton’s Bend of the river. Coal bed, 22 feet below Limestone, on west bank of Castleman’s river, + mile above Zook’s run ford, and on North Fork at old salt boring ; carries 5 feet of Shale containing 1 foot of ore balls. Coal bed A, 70 feet below B; 22 inches thick, at Shroff’s Bridge over Castleman’s river. : Conglomerate ; 30 feet below A ; the interval being massive Sandstone. Such was the general scheme of the Coal measures made out during the old survey, and, however subsequently modified, it has been of in- calculable value in all subsequent special, and private investigations. It was a very successful attempt to reduce to system the heterogeneous mass of details collected from all parts of the Bituminous Coal Region of western Pennsylvania outside, or to the east, of the Monongahela River Upper Coal Beds, and of the Alleghany River Lower Coal Beds. It was SRSA 1871.] 127 [Lesley A MAP Showing the Geographical Relations of the Pittsburgh and Baltimore C. C. and I. Co.’s Lands to the surrounding county. Pens Lesley.] 1 28 ‘ [June, by the collation of these three generalizations, that the first knowledge of the true order of the American Coal Measures was obtained, a starting point and a basis for all the Western Surveys. It was merely a sketch, however; done hastily, in a single season, and with most inadequate means at our command. In pecuniary power the party fell so low that one of our camps on the North Fork could not be { moved, because the whole party could not raise, amongst them all, 374 cents to pay a farmer’s bill for potatoes. A messenger was dispatched to Hanna’s at the Turkey-foot, now Confluence, with a faint hope of receiy- ing from the Chief in Philadelphia a remittance. Happily a letter was lying in the Post office which relieved our embarrassments. Every subsequent private survey has revealed both the general accuracy and the special inaccuracies of the summary statement of the Fifth Annual Report; and there is work for competent local geologists for a long time to come, tracing the principal members of the column, observ- ing their variations, intercalating the more insignificant deposits, and discovering their sudden, and local, and valuable expansions. We know but little yet of the true nature of the genetic relationships of coal, car- bonate of lime, and carbonate of iron. But we know that they bold some curiously fixed relationships of the highest economical importance. Every special survey, therefore, should be published, in the hope of taking another step towards a complete understanding of that subject. It is with this view that I append a special description of a property recently surveyed, stretching for five miles along the North Fork of the Youghiogheny. The North Fork is the Laurel Hill Creek of the Fifth Annual Report. Its mouth and that of Castleman’s river makes the Turkey Foot at Confluence. Ursina is a new village one mile up the Fork. The new Baltimore and Pittsburgh Railway is constructed up the south side of the Fork past Ursina, where its grade is.90 feet above water level. It then passes (by a tunnel) through the hills, and continues its course eastward up the North bank of Castleman’s River. Ursina is 86 miles by railroad from Pittsburgh, and 248 from Baltimore. here are 6436 acres in this property, and its greatest width of two miles carries it across the centre of the Coal Basin so as to include both dips; which, however, are very gentle, nowhere exceeding 5° and seldom as high as 19, There is also a gentle lowering of the central belt or axis of the basin southwestward towards the Turkey foot, which has determined its strik- ingly romantic topography. The hills of nearly horizontal coal measures are 300 to 400 feet high, and the coal beds, etc., pass through them from valley to valley cropping out in nearly horizontal lines along their sides and around their ends. Easier conditions for mining cannot be imagined. And it is in a country quite destitute of faults. . The coal beds belong to the upper part of the Lower Coal System. [Lesley. 129 1871.] The Six Foot Coal Bed outcrops on the hill-side, over the town of Its outcrop Ursina, at an elevation of about 200 feet above the water. keeps at about this height along the east flank of the Ridge (Minder’s and Sander’s hill) for two miles, up the west bank of the North Fork. Tt crops out on both sides of Minder’s creek, as high up as the forks, where it gets under the water of the run, which descends rapidly.

In this Northern part of the property it lies also in the best manner possible for mining ; falling gently in all directions towards a central point, or mining location, between the mouths of Smith’s and Brown’s creeks. ‘The arrows on the map (fig. 1) show the direction of the fall of the coal. The two parallel lines (from R R northeastward) show the central axis of the basin, or deepest part of the coal bed, falling towards BaB0o + We Down this central axis the coal bed falls at the rate of less than 1°; or, between 60 and 70 feet in the mile. The fall from the Krieger bank to the Rose bank, W. 8. W. is 150 feet in a little less than a mile. The rise from the Rose bank to the crop, up May’s creek, northward, is 120 feet in a little over a mile. The following openings on this Six Foot Bed have been worked for several years :— The Krieger Bank one mile up Brown’s creek, south side ; 9 feet above the water-bed ; runs in 109 yards, E. 10° 5. ; coal mined from several small breasts, not many tons altogether.

The small percentage.of water in these coals is remarkable. The coal is friable and comes out much crumbled, and will not bear transportation, but makes a very nice grey even coke. The crumbling shale roof will call for very careful mining and abundant timbering to keep the mine in good order. But while timber is abundant in the district, longwall mining will let the roof fall behind and afford plenty of slate stuff for gobbing up, where needful. The Rose Bank, opposite the mouth of Brown’s creek, facing south, 220 feet above water ; shows six feet face of coal, very good, except that there are a few thin layers of slate in the top bench of 12 inches, as be- fore ; a coal of 8 inches is said to underlie the bed, as before ; roof, again, crumbly shale ; coal very friable; it is roughly coked in the open air in front of the mine and makes good coke. : The Kuhiman Bank is opposite to the Rose, on the west side of the valley ; and an old mine is % mile further west on the same outcrop, and at the same level, 25 feet above the bed of Sander’s run. Both are fallen in. The people say that the bed exhibited the same character as on Brown’s creek. The bed has not been fully opened at the southern end of the property, put I see no reason why it should differ in quality or thickness here from where it is opened further up the North Fork, since it runs with remark- able regularity of thickness and character from the Krieger bank (up Brown’s creek), to the Kuhlman bank and the old opening on Sander’s creek, a distance of two miles. Geologically, this bed is the continuation southward, into Maryland, of one of the Freeport beds of the Alleghany River System, having a wide extension through western Pennsylvania, and usually furnishing the best of coal. For want of special instrumental surveys in the country south of the Conemaugh, it is not now possible to assert positively to which of these two Alleghany River Coal beds the Six-foot coal, in southern Somerset county, answers best. Our best guide, the great lime rock which underlies the upper of these beds, thins out as it approaches the Allegheny Mountain and the Maryland line. But as we have a dark Shale, with limestone nodules, overlying our Six-foot coal bed, and be- neath what is probably the Mahoning Sandrock, in the same position as that occupied by the upper of the two Allegheny River beds, the Six-foot coal would seem to be the lower. If a colliery were established at the mouth of Brown’s creek, and three incline planes ascended the ends of Younkin’s hill, Menard’s hill, and Hyatt’s hill, then from the tops of these three planes, three main entries would have three unbroken coal fields straight before them, with a rising coal; in Youngkin’s hill rising eastward ; in Menard’s hill rising northeastward, north northeastward and northward ; and in Hyatt’s hill rising west northwestward. The point is a rare one for large mining operations. —S ee 1871.] 133 [Lesley.

When the main gangways become inconveniently long, their air-ways along the outcrop will afford the most convenient outlets for slack and waste ; and new gangways can enter any where, because the drainage of the mine will be perfect. A fine colliery can also be established at the forks of Minder’s Creek, a mile and a half above its junction with the North fork. Here the Six Foot bed strikes the water level of the run; gangways may be driven in horizontally west, northwest, north, northeast, and east, commanding an entire square mile of coal lands, or six million tons of coal. The tramroad for such a colliery will be, say 14 miles long, with a grade of 10, or be- tween 90 and 100 feet to the mile, which may be lessened by judicious arrangements. This point has another advantage : it will permit alJ the Sander’s Hill coal to come out, down grade. I never saw a more beauti- ful situation for a first class colliery on bituminous coal. Nor do I know of a better coal on which to establish a great coke trade. The Turkey-foot is likely to become a second Johnstown, in the way of iron works, occupying precisely the same position, geographical and geological, upon the Baltimore and Pittsburgh through railway line, which Johnstown occupies on the Philadelphia and Pittsburg through railway line, as the map on page 3 will show; and just as Blairsville and Con- nellsville occupy precisely analogous situations, geological and geograph- ical, to each other. At Ursina, the coal beds, iron ores, limestones- oceur in the hills in the same way that they do at Johnstown; the hills are of the same sbape; and the minerals lie at the same angles with the horizon, and at similar heights above water level. At both places the Pittsburgh and Green county coal beds are absent, swept from the tops of the highest hills. At both places the blue carbonate iron ore of No. XI. underlies the conglomerate on the flank of the moun- tain near the top. And as Johnstown gets brown hematite ores from the limestone valleys of the Juniata, and fossil ore from Frankstown, and Lake Superior ore from Cleveland, to mix with the ores under the coal beds in its hills, so Ursina can get fossil ore and brown hematite from 1871.] 135 [Lesley.

Both the gold and iron range continuously with the exception of one break, in New Jersey, from Quebec, in Canada, to Montgomery, in Alabama.

All contain iron, which has been peroxidised and hydrated, in the process of decomposition of the whole formation, and dyes the country soil with a deep red tint. Or, more properly speaking, the surface of the whole country is streaked with belts of red and gray soil, following the outcrops of the more weathered and the less weathered beds. But, even in the gray belts, the solid granite, or gneiss, or sand-rock, seldom appears at the surface, although outcrops of them can here and there be found ; and a number of these outcrops are desig- nated upon the map, close to, and on each side of, the Tuscarora ore-belt outcrop. The surface of the country, therefore, is a smooth, soft, undu- lating plain, broken by gentle vales, the bottoms of which are never more than one hundred feet below the plain, and commonly not more than half that depth. The roads show how readily the rock soil absorbs water and . dries off again. The soft, mouldered condition ofall the rock strata, to depths of 50 or 100 feet, is therefore easily understood. But the rapidity with which the erosion of the land goes on is surprising. An old bridge, built a century ago, over a stream near the Quaker Meeting House, and of course several feet above the water, is now buried to a depth of 6 feet beneath the surface of its little meadow. Two general results follow from this universal ancient rainwater decom- position of the surface of the country, tothe depth of the deep valley drain- age plane :— 1. All sulphur, We., has been washed out of the ore-beds, leaving the ore remarkably pure. Whether the ore-beds, when followed down for hundreds of feet or yards into the earth, will be found to keep a notable percentage of sulphur, cannot now be known. But, whatever sulphur was originally combined with the iron, has been removed from the upper parts of the beds. 2. The decomposition of the rock strata, which inclose the ore-beds, has weakened them so that extra care must be bestowed upon all shafts and tunnels sunk or driven to win the ore, to keep them safe for mining operations. When the more solid strata, at various depths beneath the surface, are reached, mining operations will be as simple and safe as in any other region. The hills being never more than about one hundred feet above the valley- bottoms, the ore-beds can be mined by horizontal self-draining adits, or tunnels, only at well selected points. But, seeing that the ore-beds run in straight lines for long distances, a large quantity of ore can be thus taken out, for some years to come, The belt of outcrop of ore-bearing rocks has a uniform breadth of sey- eral hundred yards, and, I believe, a uniform dip towards the northwest, or north-northwest ; although there are appearances (to be stated in de- tail hereafter) which would lead the casual spectator to conclude that the outercp was double, and not single; that is, that the belt is synclinal, the ore-beds descending from the southeast side, downwards, northwestward to a certain depth, and then rising again to the surface. But the general 1871] 145 [Lesley. considerations against this view ave so strong, that I reject it without much hesitation ; and I give my reasons further on. The map, however, shows another ore belt running nearly parallel with the Tuscarora Forge Outerop, and at a distance of three miles from it. This is called the Highfield, or Shaw Outcrop. Beyond the Haw River these two belts approach each other, and are believed to unite in Rocking- ham County. This, and other considerations, make it almost certain that the Shaw belt is the Northwest outcrop of a synclinal basin, three miles wide, and that the Tuscarora Belt is the Southeast outcrop. Ifso, the Tuscarora ore beds descend, with a N. W. dip, to a depth of a mile beneath the surface, and then rise again as the ore beds at Highfield and Shaw’s ; thus: Fia. 6. Weck MECeeraten's How Thagkers, Ficdimont raclroad Atte, sity! ange Many of the outcropping ore-beds are, to allappearance, vertical; others dip irregularly, some southeast, others northwest ; some steeply, others gently. But all these are extremely local variations, confined to a few feet or yards of depth, and will not invalidate the general uniformity of northwest dip of the whole Tuscarora Belt, and southeast dip of the whole Shaw Belt. The following section of beds on (fig. 7) the Widow McCuisten plantation (14—15 miles), in a trench cut at right angles to the outcrop, 50 feet long, and from 4 to 8 feet deep, will illustrate these irregularities :— Fie. 7. _smeneeret —@ iit ( e eta* = a ae a eee r.

Besides which, there are in fact two beds cut in this shaft-tunnel, the smaller bed underlying the other, and with a dip which would carry the two beds together at some distance beneath the floor.

They have no well defined walls ; they have no selvages ; there is no gangue-rock different from the rocks on each side ; they have, there- fore, not been formed in crevices subsequently in a later age after the uptilting of the formation ; they have neither been ejected voleanically from below, nor infiltrated aqueously from above, nor secreted chemically from the wall rocks ; in a word they are not at all ‘‘yeins.’? On the con- trary they are ‘beds ;”’ beds deposited, like the rest of the rocks, in water ; deposited in the same age with the rocks which hold them; are in fact rock-deposites highly charged with iron; and they differ from the rest of y the rocks of the formation in no respect, excepting this: that they are more highly churged with iron. 1 can best represent the facts of the case by an ideal diagram of the rocks of the ore-belt in their original horizontal position, somewhat thus: Fie. 9. In fact all our primary (magnetic and other) iron-ore beds obey this law. 147 [Lesley 1871.] They are merely certain strata consisting more or less completely of per- oxide of iron, with more or less intermixture of mud and sand, which, when crystalized, fell into the shape of feldspar, hornblende, mica, quartz, etc., etc. To show that this is not mere theory, but actual fact, I compare here the section of magnetic iron-ore beds worked out on Durham Creek, near Easton, Pennsylvania, a map and sections of which can be seen by reference to W. Brook’s part of the New Jersey Geological Re- port, by Prof. Cook, 1868, page 332, and given in Fig. 10. Fia. 10. Ty lo. & ‘S / f ) —— Level of tld Tennel Bia gs ck Ge cee ‘oa aw S& Tt follows then from the above mentioned facts : 1. That the Number of Ore beds in such a formation cannot be stated. A large number of rock strata will become ore-beds locally. But there will always be a particular part of the formation more generally and extensively charged with great quantities (or a high percentage) of iron than the rest. In other words, the iron of the formation as a whole is concentrated along one or more lines. This is evidently the case with the Tuscarora Ore Belt, as is shown by the almost perfect straightness of the outcrop of the Sergeant Shaft ore-bed, where its outcrop has been opened for half a mile northeast of the shaft. There are two principal beds cropping out on the Teague plantation, at the (southwest end of the belt), both vertical, and about 300 yards asunder, thus: Fig. 11. Fie. 11.

On this Shaw Plantation, where three or four distinct and parallel beds have been opened, as seen in the preceding chart and diagrams, the di- rection of the bed changes somewhat, being N. 30° to 85° E., at the “Old Revolutionary Pits,’’ and more nearly easterly at the openings recently made by the Company. The whole course tested amounts to over half a mile. The beds at the outcrops vary in thickness from one to six feet. At ¢’’ the ore-bed is full 6 feet across solid ore—a very green, chloritic, mica-slate rock-ore. In this run of 800 yards, there are, apparently, two hundred thousand tons above water-level, in the one six-foot bed. 1 49 [Lesley. 1871.] The ore is good. The outcrop runs along the top of a hill, about one hundred feet above the bottom of the Haw River Valley, and can be tunnelled into at that depth.

The distribution of pieces of ore over wide sections of the outcrop of the ore-belt, is a notable thing. Along certain narrow lines inside the belt, are to be seen multitudes of fragments lying on the ground, which have been left behind when the rest of the rock has been mould- ered and washed away. And sometimes these fragments are a foot or more in diameter, although commonly smaller. Formerly, the ground was abundantly covered with them, but they were the first ore sought and used, and most of the large pieces and patches have disappeared du- ring the war years of 1861, ’2, ’8 and ’4. 4 Large pieces on the surface are the best evidence we can possess (in the ease of unexplored ground) that the beds are of a good size, for they have come from those portions of the beds (a,b, c, &e., in the accompa- nying diagram, (fig.15), which have been destroyed in the general lowering of the surface of the country. “There is no reason why the parts of the ! beds left under the present surface (a/, b’, ec’, &e.), should not yield as large masses as the parts a, b, c, which have been mouldered away. 2. The Size of the Ore Beds varies as much as their number. They con- sist of strings of lens-shaped masses, continually enlarging and contract- ing in thickness, from a féw inches to six and eight feet. The principal beds may be safely estimated on an average of four feet, or 176,000 tons to the mile, with an average breasting of 60 feet above water level. Itis needless to say that an equal amount would exist beneath water-level, for every sixty feet sunk on the bed. 3. The Quality of the Ore.—It belongs to the family of the Primary Ores. It is very similar to the New Jersey ores which are so extensively 1871.] 151 [Lesley. mined for the furnaces on the Lehigh river. It is a mixture of magnetic crystals, and specular plates of sesquioxide of iron, with quartz, feldspar and mica, in a thousand varying proportions. Sometimes the bed will be Fre. 15. composed of heavy, tight, massive magnetite (or titaniferous magnetite), with very little quartz, &c. At other times the bed will be composed of a loose, half-decomposed mica slate, or gneiss rock, full of scattered crys- tals of magnetic iron. The ore is, in fact, a decomposible gneiss rock, with a varying per cent- age of titaniferous magnetic and specular iron ore, sometimes forming half the mass, and sometimes constituting almost the whole of it. The compact varieties will yield between 50 and 60 per cent. of pure iron, as in the case of the ore now being mined in the Sergeant Shaft, near the Forges. Mr, Frazer’s analysis of this ore is as follows : Magnetic OIGG,,....-.-.- SM OCUO sie vrs ok ATOM, ose. Ob. 0. Cell WIGAN Ol es os Save?

The specimen was obtained from the tunnel, a hundred feet beneath the surface, and shows an intimate mixture of crystalline titanic ore, magnesian mica, a little hornblende, a little labradorite, and a little spec- ular iron. This kind is difficult to smelt in the high-stack blast-furnace ; but makes the best iron in the world when smelted in the Catalan forge ; and is of great value for the lining of puddling furnaces. It serves the same purpose as the Lake Superior ore, which is brought in large quantities to Pittsburgh, and the surrounding district of Eastern Ohio and Western Pennsylvania, for lining puddling furnaces, and to mix with poorer ores | in the blast-furnaces. Formerly, in the E. Ohio Mahoning district, the mixture was: one-fourth Lake Superior, one-half coal measure ore, and one-fourth mill cinders. Since the organization of the Lake Superior Iron Ore Trade, sufficient quantities come forward to enable the iron masters to mix one-half Lake Superior. The Sharon Furnace on the Beaver river runs wholly upon Block Coal and Lake Superior Ore. The titan- iferous magnetic ores of the Ottawa region, in Canada, are also brought by.a long and expensive route to Pittsburgh, to mix with Pennsylvania Lesley.] 152 [June 16, ores. These Canada ores are of the same geological age, and of the same mineral character, as the Tuscarora ores under consideration. Trial of the ore has been made by Mr. Nathan Rowland, at his works in Kensington, Philadelphia. Five tons were forwarded for trial as lining to puddling furnaces. Mr. Rowland expressed his opinion that it stood up three times as long as the Champlain ore, which he uses for that pur- pose. The difference is due to the superior compactness of titaniferous magnetite over that of pure crystalline magnetite. LT have said above, that the Tuscarora ores are essentially like those of Northern New Jersey. I-referred to their age, situation, consistency, and general composition. But they have a peculiarity ; they hold a no- table per centage of tétanic acid. 'The New Jersey ores seldom possess this property, and, in any case, only ina low degree. The Canada ores, and the ores of South Sweden, hold large quantities of titanic acid ; even as much, sometimes, as between 80 and 40 per cent. A small—a very minute—quantity of titanium in pig-iron is believed to add greatly to its value, increasing its hardness and firmness, and its ability to stand wear. The Canadian ores were introduced to the Pittsburgh iron works for this end. But, seeing that almost all the titanic acid in any iron ore passes off in the slag, leaving a very small quantity to unite with the pig metal (sometimes in scattered crystals), it follows, that ores, which have an excessive quantity of titanic acid, cannot afford a high per centage of pig metal. It is much better to have an extra 20 per cent. of silex and alumina, potash or lime, in the ore, than an extra 20 per cent. of titanic “acid ; for these will make the ore easy to smelt, whereas the titanic acid makes it difficult to smelt ; requiring a much higher heat in the stack to decompose than does oxide of iron. There isno question that titanium in iron ore favors the production of iron peculiarly suited to conversion into steel. The English steel trade has always largely depended on Swedish iron; and I believe that the titaniferous ores of the United States (and they are far from abundant, ) will become annually more and more valuable, on account of the increas- ing demand for the best iron for steel-making purposes. If these ores were smelted in large quantities in first-class anthracite furnaces, I do not think this particular value would appear; the small Swedish blast fur- nace must be used, or the Catalan forge. Although the action of titanium upon iron in metallurgy is an obscure subject, something is known of it by actual experience. J. H. Alexander, of Baltimore, in his report on the Manufacture of Iron, gives analyses of certain cinders, among which is one obtained in the smelting of a primary iron ore, containing, he says, 11 (eleven) per cent. titanic acid: the analysis is as follows:— Biioe: eke ok Ouide of Titantum........ 9.0 Magnesia i005 0 ena cee 84.2 Protox. manganese....... 4.4 Letts catend eG dae 14.1 PPROLO Sse ION geass cake 1.0 A MMOING a Uae can resi 8.9 The ore, he says, was hard to smelt, and the pig-iron hard to work, but when properly made, is peculiarly adapted to the manufacture of steel. 1871.] 155 : [Lesley. The explanation is as follows:—Titanie acid will not combine readily with either the acid or the alkaline oxides. In every ton of ore (holding 10 per cent. of it) 320 Ibs. of this neutral stuff exists, or (14 tons of ore to 1 ton of iron) 830 Ibs. of it in every ton of iron. If only 1-10 of this (or 83 lbs.) remains in the furnace, the gradual accumulation blocks it up. The only solvent of it are the double silicates of iron and lime, or iron and alumina and lime, or iron and potash and lime, &e. To make these double silicates, we must waste a good deal of iron, But the one object of the blast furnace is to save all the iron, and the best cinder is that which has no iron left in it, all the iron of the burden having gone down into the hearth as pure metal (with enough carbon to make it fusi- ble). The Catalan forge, on the contrary, wastes iron, and its cinders are so rich in iron, that they are often worked over again ; hence, titanic acid is carried off, and does not obstruct the hearth. The forge fire is, therefore, the best to reduce titaniferous iron ores. But the blast fur- nace can smelt them also, if the heat be kept low, and some of the iron be allowed to go to waste in the cinders, to carry off the titanic acid and cinder mass. The object then, must be to make the utmost quantity of the most fusible cinder; therefore, a blast furnace running on titaniferous ores, should not be fluxed by pure limestone, pure clay, or pure sand, but with ferruginous clay, ferruginous slate, or ferruginous limestone. These fluxes will dissolve titanic acid at a low heat. To get gray pig iron, the cinder must be abundant ; to get white forge metal, but little flux is need- edin comparison, the ore itself being wasted to form cinder. This white iron with a large amount of carbon in it, is just the metal from which terman steel is manufactured. A high stack and a small hearth, like the Styrian furnaces, and ferruginous fluxes, are the best for titaniferous ores, Osborne says (page 475), that Mr. Henderson writes him that the Nor- wegian ores are successfully used at Norton, England, on a plan inyented by John Player, although they contain (by one anlaysis) CEitanG WCieieg oe ee Chey eS eee 40.95 POLO A IPONS eccrine, oi) ceb eee tisaes 22.63) 51 59 Prokos MON es ree ee re es 26.96 Magiesian ¢ 2055. o.oo oe fp iy ge 9 | Alumina Sie a a eats wee ee ean ZRII Ss "St UGH ies os el nee en es For a 42 { PVOUOR) WANG, foo es Sys se 56 J 100.35 being smelted in small furnaces with 1000°F temperature of blast, 2 tons of coal to 24 tons of ore, 15 cwt. of limestone, 10 cwt. basalt rock. «The iron becomes titanized, and is found to be exceedingly strong, and is used in Europe for armor plates, commanding three times the price of ordinary pig iron. The tensile strength of the resulting wrought iron, when puddled, is about 52} tons to the square inch.

The lighter and looser varieties of the Tuscarora ores have a lower per centage of iron in them, but will work more kindly in the blast-furnace. I had Mr. Frazer make me an analysis of a piece of outcrop ore from the Highfield plantation. It gave: Magnetic oxide, 44.53 [metallic iron, 32.25]. These varieties make equally good iron, and iron as well adapted to the manufacture of steel. The hard and soft varieties of ore occur often within a few hundred yards of each other ; as, for example, on the Widow McCristen’s planta- tion (14-15 miles), where the soft outcrops are seen on the hill opposite the house, and the hard ore lies in large chunks on the hill, south of the swamp. I append Dr. Genth’s analysis of specimens from the two places, made at my request: 1. Massive ore from Mrs. McCristen’s Plantation. The analysis was so unexpected in its character, that Dr. Genth suspected some error, and repeated it, but with the same result. The small amount of titanium shows the varying nature of the deposits. The percentage of iron is also low for this kind of ore: IVOT ies ie gf 88.97 p.c. Bip auinyanl | ese! ee 1.60 [=2.63 p.c. titanic acid.] Ratio Of item TO drones a B.S a ee 1: 21.24. 2.

The ochre must become a fluid double silicate, without robbing the ore, and will carry off the titanic acid in excess. One of the constituent elements of the whole formation is Ochre, in beds of various sizes. What the exact geological relationship of these ochre beds to the magnetic ore-beds is, I do not know. But the ochre outcrops seem to be always in the immediate vicinity of the ore-beds. The largest exhibition of ochre which I saw is on the J. Somers Planta- tion on Brushy Creek. Here an ochre bed twenty feet thick rises, nearly vertical, out of a gully in a hillside covered with small pieces of fine com- pact ore. Bar-iron Analysis, by A. A.

Therefore I would judge that part of the impurities is from oxide of iron, and the remainder from slag, which I have ascertained ex- perimentally. In other words, the impurities are due to a highly basic slag, which cannot be expelled or squeezed out by the hammer and the rolls.”’ Norz.—The above bars were rolled (from blooms of N.

Fesquét assisted at the conversion of ten tons of North Carolina blooms into steel, at Cooper & Hewitt’s Works, Trenton, N. J. The blooms were some of the first made at the Tuscarora Forge fires, rough and variable in size and quality, and weighing from 150 to 225 lbs. Mr. Fesquét thus reports ; The Siemens-Martin’s Process consists in mixing steel scraps with pig iron. The Carbon of the pig iron reduces the iron oxidized by the flames; keeping watch, as it were, over it, and preventing the perpetually forming oxide of iron from forming a cinder with the silica of the furnace lining. The charge being melted, it remains exposed to the flame until, and even after, all the carbon is burned off. The exact moment is known by a series of samples being taken out, hammered and bent, hot. If the samples be red short, Franklinite iron is added to restore enough carbon to remove the oxygen from the iron. After one or two stirrings the metal is run into moulds. The North Carolina blooms took the place of the steel scrap. The cast iron used was West Cumberland (English) pig, nearly free from sulphur and phosphorus, and with enough silicon and carbon to fit it for Besse- mer use. At the moment of complete decarburation asample was taken. It was slightly red short. An analysis showed that the red-shortness was due to a minute proportion of oxide of iron and cinder, which had not been expelled because of the pasty condition of the decarburetted metal. Per- centage of carbon less than 1-1000th part. Franklinite was added; the metal became fluid, and was run into moulds. The ingots were sound, and presented large crystals, of a clean gray color. A sample from one was perfectly malleable, without a trace of hot or cold shortness, without a flaw, and homogeneous to all appearances. The large crystals were céndensed under the hammer. The fracture was not jagged, and resembled that of cast steel of some degree of condensa- tion and hardness. In a word, this steel was malleable, homogeneous and tough, like the best steel produced in any other way. af Tried at the forge fire (by the same workman), it seemed to bear more heat for welding and hardening than will the ordinary steel (with a gor- responding proportion of carbon). Less carbon is necessary in the case of titanium steel than in the case of common steel, to arrive at the same hardness. In the rolls, this steel manifested no difficulties, according to the testi- mony of Mr. Slade of the Trenton Works. : Waste: Three operations, 14,152 lbs. of metal inall; waste, 13.5 per cent., June 16, 187L.] 158 [Lesley. exceeding somewhat the waste when steel scraps are used ; for the cinder in the blooms has to be purged off in the process, and secondly, the almost purely metallic titaniferous bloom iron is much harder to melt than scrap steel ; is longer exposed therefore to the flame, and therefore wastes more. By adding pig metal this evil will find a remedy. The peculiar qualities of this steel will no doubt be intensified when its own titaniferous pig metal is used with its titaniferous forge blooms. A dose of Franklinite may yet be necessary. Mr. Fesquét thinks it acts by giving up carbon. He suggests, however, that possibly it acts through manganese ; but as nearly all the manganese goes off in the slag, he thinks its peculiar use is to keep the cinder fluid, and taking the iron’s place in the cinder.

(Read before the American Philosophical Society, Oct. 6, 1871.) The development of any branch of science is generally a slow and gradual process, The obvious truths which suggested to Laplace his cele- brated hypothesis of the solar system had been for ages well known to astronomers ; but, as in the case of the earlier geological observations, they had been regarded, without any just reason, as ultimate facts. So now we have numerous results of observation in regard to the rings of Saturn, the zone of asteroids, the relative distances of the planets, &c., the study of which, it is believed, may lead to new and important discov- eries. ‘These hieroglyphics older than the Nile,”’ pointing back to the epochs at which the planets were born, will doubtless in the future be more or less clearly deciphered, and the ancient history of the solar system at least partially developed. It is a very remarkable fact in regard to the systems of both primary and secondary planets that the periods, without any exception, have very simple relations of approximate commensurability. This truth, though obvious on mere inspection, seems not to have attracted the special notice of astronomers, as no attempt had been made, previous to that of the writer, to assign its physical cause. A general view of these approxima- tions is presented in the following tables, where the periods of the primary planets, Mercury, Venus, &e., are represented by P!, P1?, &e., and those of the satellites by p', p!?, &c.

Oct. 6, 1871. y ’ Of those recently deceased, members of a profession which has contributed a large share of workers to the different fields of biological science, few have given greater promise, and not many among us have at- tained to better performance in a short career, than Edward Rhoads. Unfavorable for the full appreciation of his work, except by those with whom he was closely associated, has been the fact that much of it has been unrecorded ; being the daily labor of the practitioner and teacher of medicine. But it is fitting that this Society, whose pursuits and member- ship are not narrowly limited, should at least briefly record its recognition of such high ability and character. Edward Rhoads was born in Philadelphia, September 29, 1841. After a good preliminary training, in which an early love of natural science dis- played itself, he entered Haverford College in 1850 ; and was graduated there, at the head of his class, in 1859. The rural situation of the college afforded him an opportunity for the study of Botany, in which he became well versed while a sudent. Shortly after leaving college, an attack of rheumatic fever, involving the heart, began those inroads upon his con- stitution, the repetition of which afterwards abridged his life. In the fall of 1860 he commenced the study of medicine;,and obtained the degree of Doctor of Medicine at the University of Pennsylvania, in 1863. He was then elected, after a competitive examination, Resident Physician in the Philadelphia Hospital, West Philadelphia. This was followed, in 1864, by his appointment as Resident Physician in the Pennsylvania Hospital. In the midst of his arduous duties there, performed with distinguished success and with satisfaction to all, he was again affected with articular rheumatism, which renewed seriously the disorganizing disease of his heart. On recovering from this attack, he visited Europe, in 1865, being absent eight months. In 1866, he was appointed Visiting Physician to the Phil- adelphia Hospital ; where his professional talent, enthusiam and knowl edge, and his capacity as a clinical teacher, found free scope for develop- ment and utility. He was at the same time assiduously engaged in private medical teaching, as an examiner in connection with the courses of the University of Pennsylvania, and in giving lectures upon medical chemistry and connected subjects. In 1870 the faculty of the University appointed him its lecturer on Physical Diagnosis. His first course of lectures was interrupted by illness, which prevented his ever resuming the duties of a public instructor. In the same year, a number of gentlemen proposing to establish a new medical journal,—The Philadelphia Medical Times, —its editorship was unanimously offered to Dr. Rhoads. This duty, which enlisted all his zeal, and would have illustrated admirably his professional learning and . Hartshorne. ] u 7 2 [Oct. 20, tact, he was obliged to forego on account of his failure in health, which, after great suffering for several months, ended his life January 15, 1871. In private practice, Dr. Rhoads was rapidly gaining the confidence and success which his skill and acquirement deserved ; as well as the warm and grateful attachment of many families, —which remains in commemora- tion of his virtues, more faithful than any eulogy, and more endur- ing than any monument. He was elected to membership, besides the Philosophical Society, in the Philadelphia College of Physicians, of which he was Recording Secretary, the Academy of Natural Sciences, and the Pathological Society. To the proceedings of the latter he contributed a number of papers. He wrote for the American Journal of the Medical Sciences several reviews, showing a quick critical apprehension, a large acquaintance with medical science and literature, and an excellent com- mand of language. He assisted Dr. J. F. Meigs in the preparation of an elaborate paper, published in the first volume of the Pennsylvania Hos- pital Reports, 1868, on ‘The Morphological Changes of the Blood in Malarial Fever.”’ With Dr. W. Pepper, he contributed to the same vol- ume the results of an extended inquiry into the “ Kluorescence of the Tissues of the Human Body, especially in connection with Malarial disease and the action of Quinia.’’? The scientific spirit which animated all his professional labors, and which he brought to the investigation of the great problems of Pathology and therapeutics, thus elevating the vo- cation of the physician far above routine, was well exemplified in this paper. Its preparation was suggested by the remarkable observation of Bence Jones, by whom a fluorescence resembling closely that of a solution of quinine was found to eccur in solutions of the tissues of animals which had taken none of that substance. A peculiar fluorescent organic princi- ple was here inferred to be a normal constituent of the animal body ; and to this Bence Jones applied the name of ‘ Animal Quinoidine.”’ It was not an irrational hypothesis, that the systemic effects of the malarial poison may be attended by an injurious deficiency of this material ; and that quinine, or the other extractives of Peruvian bark, may be remedial for the disease, by supplying the system with its equivalent. Drs. Rhoads and Pepper undertook first, to ascertain whether, by chemical and spectroscopic analysis, there could be shown to be a marked diminution in the amount of animal quinoidine in the body under the in- fluence of malarial disease. They also gave attention to the effect upon the animal fluorescence produced by the treatment of the attack by sul- phate of cinchonia. The interesting result was arrived at by a series of careful and exact determinations, that there is, uniformly, a close con- nection between malarial disease and the diminution of ‘animal quinoi- dine ;”’ and that this connection is apparent, not only in the presence of a fully developed paroxysm of fever, but also when the system is more in- sidiously, though often very seriously, affected by the morbid cause. The same exact inquiry into evidence, with the aim to discover and es- tablish truth, was applied by Dr. Rhoads in his consideration, both theo- i | 1 1871.] 173 [ Hartshorne. retical and practical, of the highest topics, not only of science, but of philosophy. Contented to accept no truth upon the evidence of mere tra. dition or hnman authority, his opinions upon religious subjects, being those held by the Society of Friends of which he was a member, were the result of deliberate and strong conviction. His fine critical faculty was brought to bear upon the recent Biblical and anti-Biblical controversies, represented, upon the one side, in different modes, by Strauss, Bauer; Comte, Renan and Buckle. In several essays, prepared for special occa- sions, only one of which, however, has been published, he displayed a calm mastery of these topics, an amount of knowledge and force of argu- ment, such as might be looked for rather in a professed theologian than in an active member of the medical profession. With all who knew Dr. Edward Rhoads, however, his intellectual en- dowments, though great, were always perceived to be subordinated to moral qualities more rare and admirable. From early youth, purity of life, unselfishness, refinement and elevation of mind, were his marked characteristics. Few examples so spotless are met with in any profession or sphere of life. In the large assembly which met at his funeral, words spoken by several who knew him well, and whose standard of character was high, were such as might fulfil the aspirations of the most saintly of men, and which very few, indeed, could deserve, Stated Meeting, Oct. 20, 1871.

My Dear Prof. Lesley :— I write to give a brief account of the expedition of seventeen days, which I have just made in the valley of the Smoky Hill river in Kansas. Through the courtesy ef Gen. Jno. Pope, commanding the Department of the Missouri, I was furnished with an order on the post commandant at Fort Wallace for a suitable escort. This was furnished by Capt. HE. Butler (5th infantry), who spared no pains to make the expedition a success. We first camped at a spring eighteen miles south of Fort Wallace, and five miles south of Butte Creek. It had a fine flow of water, and being without name I called it Fossil Spring. On a bluff, on Butte Creek, Lient. Whitten discovered the fragments of a monster saurian projecting from the shale, and on following the bones into the hill, exhumed a large part of the skeleton of Liodon dyspelor Cope (Proceeds. A. P. 8. for 1870). This was welcome, as the species had been previously known from ver- tebre only. The pelvic arch was found perfectly preserved, and the scapular arch and limbs partially so. The iliac bone is slender and straight, slightly expanded at the acetabulum. The ischium has a somewhat similar form, but is curved. The axis of the proximal portion is directed upwards; the shaft then turns into a horizontal direction, and lies be- neath and at one side of the vertebral column without uniting with its fellow. The pubes are elongate, but wider than the other elements and flattened. They are in contact in front medially, and have an angulate axis. A short process projects from near the proximal end, on the ex- terior margin. The femur is a flat bone, slightly constricted medially, and with a decurved and projecting portion of the proximal articular, surface on the inner side representing a head. The extremities of the dentary bones are each drawn to an acute point differing thus toto coelo from those of the LZ. proriger. On the same bluff another Liodon and a Clidastes were found, with five species of fishes. On examining neighboring bluffs and denuded areas, bones supposed to be those of Prerodactyle, two species of Clidastes, a Dinosaur, a Croco- dile, and numerous fishes were brought to light. In a similar location on Fox Creek canon, one of the escort, Martin V. Hartwell, to whom I am indebted for many fine discoveries, observed the almost entire skeleton of a large fish, furnished with an uncommonly (Cope. powerful offensive dentition. The jaws were stout, the dentary bone very deep. The teeth in a single row in all the bones, but of irregular sizes. There are two or three very large canines in each maxillary, and one in the premaxillary, three or four in the dentary separated by an interval. The lack of coronoid bone and many other characters show that it should be referred to the order Isospondali, and is probably allied to the herring and the Saurodontidae. The vertebre are grooved, and there .is a basi-occipital tube but little developed. The teeth are simple cylindric conic, with smooth enamel, and project two inches above the alveolar border, and each descends an inch into ityalveolus. The species and genus are new to our palaeontology, and may be named Portheus molossus. It turned out on subsequent exploration to have been quite abundant in the Cretaceous seas. It was probably the dread of its cotemporaries among the fishes as well as the smaller saurians. On another occasion, we detected unusually attenuated bones projecting from the side of a low bluff of yellow chalk, and some pains were taken to uncover them. They were found to belong to a singular reptile, of affinities probably to the Testudinata, this point remaining uncertain. Instead of being expanded into a carapace, the ribs are slender and flat. The tubercular portion is expanded into a transverse shield to beyond the capitular articulation, which thus projects as it were in the midst of a flat plate. These plates have radiating lines of growth to the circumference, which is dentate. Above each rib was a large flat ossification of much tenuity, and digitate on the m argins, which appears to represent the dermo- ossification of the Tortoises. Two of these bones were recovered, each two feet across. The femur resembles in some measure that ascribed by Leidy to Platecarpus tympaniticus, while the phalanges are of great size. Those of one series measured eight inches and a half in length, and are very stout, indicating a length of limb of seven feet at least. The whole expanse would thus be twenty feet if estimated on a Chelonian basis. The proper reference of this species cannot now be made, but both it and the genuss are clearly new to science, and its affinities not very near to those known. Not the least of its peculiarities is the great tenuity of all the bones. It may be called Protostega gigas. The greater part of a large Liodon proriger Cope was found scattered over a denuded surface at one point, his huge truncate, bowsprit-like snout, betraying his individuality at once. Portions of other examples of this reptile were afterwards found. Remains of several species of Cli- dastes occurred at various points in the neighborhood of Fossil Spring. One was found in the side of a bluff fifty feet above the bottom of the cation ; Martin Hartwell exhumed another near the 0. cineriarum Cope almost complete. We subsequently left this locality and encamped at Russell Springs on the Smoky Hill, twenty-six miles distant. On the way a large Olidastes of some forty or more feet in length was found lying on a knoll of shale, with the head displaying the palatal surface upwards. On the Smoky . Cope. ] 1 76 (Oct. 20, 1871. our explorations were attended with success. When we shifted camp, it was to go to Hagle Tail in Colorado, whence we returned again to Fossil Spring. The richness of this locality was again apparent, and we added. to our collection a number of species. Among these may be mentioned Liodon ictericus Cope and two new Clidastes. The writer originally pointed out the existence of representatives of the orders Pythonomorpha and Sauropterygra, in this cretaceous basin. Prof. Marsh’s explorations determined the existence of Ornithosauria and Orocodilia. The present investigation adds Dinosawria and perhaps Zestudinata, or the group that the new form Protostega Cope represents. The preceding account expresses some of the points of interest observed. These, with others, now unnoticed, will be included in a final report. The giants of this sea were the Liodon proriger, Cope, L. dyspelor, Cope, Polycotylus latipinnis, Cope, and Hlasmosaurus platyurus, Cope. Of these the first was apparently the most abundant. The second was the most elongate, exceeding iu length perhaps any other known reptile. The last named had the most massive body, and exhibited an extraordi- nary appearance in consequence of the great length of its neck. For kind assistance, I am much indebted to Capt. Edwin Butler, post commandant at Fort Wallace, to Dr. W. H. King, post surgeon, and to Capt. Wyllys Lyman. To Lieut. Jas. H. Whitten and Sergeant W. Gardner, who accompanied the expedition, much of its success is also due. Iam, etc., EDW. D. COPE. Stated Meeting, Nov. 3d, 1871. Present, eleven members. Vice President, CRESSON, in the chair.

The loss by shipwreck, in a recent storm, on Lake Superior, of James T. Hodge, a member of the society, was announced by Secretary, with appropriate remarks. Prof Cope made some general observations on the extinct Batrachian Fauna of the Carboniferous of Linton, Ohio., based on studies of material obtained by Prof. J. 8, Newberry, Di- rector of the Geological Survey of Ohio. Twenty-seven species had been discovered up to the present time, and not one of them was a reptile ; twenty-three of these were referred to the following genera: Pelion, Wyman, 1 5 Sauropleura, Cope, 3; Tu- ditanus, Cope, 43 Brachydectes, Cope, 1; Oéstocephalus, Cope, 6; Cocy- tinus, Cope, 1; Molgophis, Cope, 1; Phlegethontia, Cope, 2; Colosteus, Cope, 8; Hurythoraa, Cope, 1. Tuditanus, Cocytinus and Phlegethontia were described as new genera. The first represented Dendrerpeton, but possessed the usual three thoracic shields, a character not yet found in the former genus, Phiegethontia embraced slender snake-like forms allied to Molgophis, but without ribs. Cocytinus was a branchiferous genus having four branchihyal bones, two basals branchikyals and two ceratohyals on each side, and with conic teeth in the anterior portion of the mandible only, on an expansion or dental plate. Limbs none in front. Oéstocephalus was defined as having the three pectoral shields, poste- rior limbs only present and weak ; head lanceolate ; ventral armature of packed osseous rods en chevron ; neural and haemal spines of caudal vertebrae expanded and fan-like. The six species were enumerated, viz : O. remex, Cope, O. pectinatus, C., O. marshti, C., O. curoidens, C., O. vinchellianus, ©., O, serrula, C., the last three being new to science. Other new species were described, as Sauropleura longipes, C., and 8. brevipes, O., Tuditanus brevirostris, C., 7, mordax, C., and 7. radiatus, C., Cocytinus gyrinoides, C., Rhlegethontia linearis, C., was indicated as a species with lanceolated head, no ribs, a very elongate tail, and without limbs or ventral or thoracic armature. Phlegethontia serpens, C., was a larger species. A new Colosteus, C. pauciradiatus was added, and an allied form described as Hurythorax sablaevis. The pectoral median shield is subround and nearly smooth, and belonged to an animal of four feet in length. Sauropleura, Oocytinus, Molgophis, Phlegethontia were enumerated as genera in which pectoral shields had not been observed, and Pelion and Tuditanus were characterized as the broad-headed types. A.

The more strongly marked and decisive character of the curves of lunar monthly rainfall, in Philadelphia than in Great Britain, (ante v. x., pp. 523-84, ) rendered me desirous of obtaining observations from some Euro- pean station in lower latitude. The intimation of that desire to the Director of the ‘Observatorio do Infante Dom Luiz,’”’ at Lisbon, was promptly followed by the transmission of a copy of observations extend- ing over a period of sixteen years, which is herewith presented. I also submit some of the tabulated results of such discussion of the observa- tions as I have already undertaken, which appear to me to corroborate, in a most satisfactory manner, the views I have hitherto advanced respect- ing the meteorological influence of the moon. Some of the tables also afford interesting indications of a somewhat similar planetary influence, sufficient, as it seems to me, to encourage further investigation.

Nevertheless, such of the objectors as are familiar with Howard’s discussion of the moon’s influence upon the barometer; Sabine’s, of lunar disturbances of terrestrial magnetism; or Schwabe’s and Wolf’s, of the dependence of sun-spots upon planetary configurations, seem to admit—at least I am not aware that any of them deny—the prob- ability of the conclusions which those eminent observers have severally expressed. If it is conceivable that Saturn, Jupiter and Venis can in any way affect the cloudiness, or arnount of spotted surface of the the sun, not- withstanding the immense preponderance of his attractive, magnetic and other supposable forces, it is surely much more easy to imagine that they may similarly affect the meteorologic phenomena of the earth, which op- poses an antagonizing mass only 574.55 (according to Newcomb’s esti- mate) as great as that of the sun. If the lunar tides of our atmosphere are of sufficient magnitude to affect the barometer, the consequent waves must effect a blending of aerial currents of different temperatures and TABLE II.

If the lunar are as unmistakable as the solar modifications of magnetic phenomena, the analogies which have been pointed out, by Messrs. Baxendell and Bloxam between magnetic and pluvial and by myself between pluvial and auroral curves, are indicative of other possible lunar influences which are equally unmistakable. If the difficulty of conceiving an adequate cause for a supposed phenomenon were to deter us from inquiring whether an apparent dependence were real or illusory, all progress in science would become impossible. Finally, if it can be shown that solar rain-curves exhibit different, and often contra- dictory inflections, similar to those which are objected to in the lunar curves, and if a consistency of disagreement can be shown between the lunar results at two given stations, accompanied by a consistency of agree- ment between the results in different cycles at the same station, the ar- gument from apparent contradiction will be deprived of all its force. I have no hope of thoroughly convincing any one who is skeptical of lunar influence on the weather by deductions from observations at one or two, or a half dozen stations, but I believe that any one who will ex- amine, carefully and impartially, the tables I have already published, based on observations in India, Great Britain, Portugal, Canada and different portions of the United States, will at least be willing to admit TABLE III. 1871.] 1 81 [Chase. that the question is an open one. And if he will compare my previous tabulations with those which accompany the present paper, he may, per- haps, find any lingering skepticism shaken, however prejudiced or invet- erate it may be. For convenience of comparison, I represent, in each instance, the mean rainfall for the entire period under consideration by 100, and any devia- tion from the mean, whether of excess or deficiency, is denoted by the addition or subtraction of a corresponding percentage. The smoothing by successive means is uniform in all the tables. I invite special atten- tion to the columns of lunar rainfall at Lisbon, in each of the first two tables, representing two different sets of three independent periods, averag- ing 64 months, a cycle which T have hitherto supposed too short to yield any satisfactory results. If there is no causal nexus, it is difficult to imagine any possible reason for the striking similarity between the ordinates for the different cycles, a similarity which I think quite as striking as that between the solar curves at the same station for independent periods of similar duration. If the lunar disturbances are considered as merely tidal, while the solar are partly tidal, but principally thermal, their rela- tive magnitudes suggest interesting comparisons between centrifugal and centripetal forces, analogous to those which I have hitherto had the honor of presenting to the Society. The resemblance between the independent curves in Table III. is not very marked ; but the yearly mean is curiously like the yearly averages of the lunar monthly ordinates in Tables I. and IL., if we construct the curves so as to compare the ordinate of Jupiter’s opposition, No. 16, with the ordinate of lunar conjunction, No. 1, and vice versd.

The centram is considerably wider than deep, and considerably longer than wide. The posterior chevron articulations are small, and each is connected with each anterior by a strong rounded angulation. Between the latter the space is wide and slightly concave in transverse section, least so medially. _ A marked peculiarity is seen in the strong longitudinal ridge which divides the lateral surface of the vertebra into two nearly equal faces. The neural arch is elongate, the neural canal small: in section a short vertical ellipse. The articular face of the zygapophyses makes an angle of about thirty-five degrees to the perpendicular. The crest of the arch rises a half inch behind these into the very stout basis of the neural spine, the . greater part of which, with the posterior zygapophyses, is broken off.

The peculiarities of this vertebra indicate most strikingly the generic distinctness of this great reptile from the Hadrosaurus. It is true it presents some similarity in form to the terminal caudals of that genus and if it could be referred to that portion of the series, would indicate merely another and larger species of Hadrosaurus. It differs inform from these vertebrae, in its depressed instead of compressed form, and its lateral angulation. That it belongs to a more anterior position in the tail is evident from the very large size of the basis of the neural spine, and general greater development of the neural arch and zygapophyses, and the trace of diapophyses. Further, it is over four times the size of the terminal caudals of H. foulkei, while the remaining elements do not indicate any such extraordinary dimensions. A position a little behind the middle of the series would relate well to the other proportions. This is another of those remarkable forms which the reptilian type developed in past ages. That it was herbivorous, and relied less on its tail for support than Hadrosaurus, appears probable. Large caprolites of the character of those of herbivorous animals accompanied the bones. They resemble somewhat those of the hog ; one has a diameter of 3.5 inches one way, and 2 inches the other; extremity broad, obtuse. The pro- prietor of the pit told the writer that he had more than once seen large ‘*hoofs’? ‘‘and wide toe-joints’ taken out during the excavation. This species is different from the Ornithotarsus immanis, Cope, and belongs to a different genus. The shaft of the tibia in the latter is filled with cancellous tissue ; in the present.animal it is entirely hollow. From the marl pits of James King. Haprosaurvs, Leidy. HADROSAURUS TRIPOS, Cope. Ata point about ten miles distant from the marl pit in which the Hypsibema was found, Prof. Kerr discovered a caudal vertebra of a colossal reptile, whose affinities are evidently near to the Hadrosaurus foulkei. This vertebra is one of the distal, as evidenced by the entire absence of any trace of diapophysis, and its subquadrate longitudinal section, as well as by the small size of the neural arch and spine. At first sight it would appear to occupy a position between the thirtieth and thirty-sixth of the series; the former in H. foulkei has, however, rudiments of a diapopbysis. Both its articular faces are distinctly biconcave. The large OTA 1871.] . LO [Cope. size of the chevron articular face is as in the thirtieth, and the concavity of its lateral faces as in the twenty-sixth; in the thirty-sixth the sides are entirely plane. The round form of the neural canal, as well as lack of diapophysis, are points of resemblance to the thirty-sixth, but it is more than twice as long as that vertebra in the H. foulkei. In the thirtieth the neural canal is somewhat depressed and becomes more so as we advance towards the proximal part of the series. The small antero-pos- terior extent of the neural arch is much as in the thirtieth in H. foulkei, but the basis of the neural spine, which is broken off in this, as well as the odd species, is much more slight. It isso very thin and weak as to indicate either comparatively a slight development of the spine, or a very posterior position in the series. A weak lateral ridge marks the side of the centrum, which is below the middle line. It holds the same position in the thirty-sixth in H. foulkei, but is above the middle in the thirtieth and those anterior. Measurements. In.

Frievp, or Lonpon. Read before the American Philosophical Society, December 1, 187i. It is the painful duty of our Society to record the loss we have sus- tained in our membership, and indeed we may well say, the loss to the world in general, by the decease of the illustrious Sir John F. W. Her- schel, Bart. His father, Sir William Herschel, came from Hanover to England, in 1759, as one of the Hanoverian Guards’ Band; and was for some time the subject of disappointment and privation. He however became instructor to a regimental band, stationed in the North, and fortunately obtained an organist’s appointment in Yorkshire, and subsequently at Bath. Here it was that his taste for astronomy became developed, and from whence his first papers, ‘Observations of the Periodical Star Mira Ceti ” issued. They were read before the Royal Society, in London, on the 10th May, 1780. : In 1781, the results of his studies and speculations led to his great dis- covery of Uranus (specially interesting from its leading to the discovery of the remote planet Neptune) which placed him most prominent in Sci- entific rank, which standing he retained until his death in 1822, being then in his 84th year. Mr. Herschel, our lamented member, (unlike his father who raised him- self from the humble rank of a regimental musician) after being edu- cated privately by a Mr. Rogers, at an early age entered St. John’s College, Cambridge, where by his great success and taste for science he graduated B. A. in 1813. He came outin the Mathematical Tripos, Senior Wrangler; an honor which was further enhanced by his attainment of the Firs Smith’s Prize. That his year was what is called, in Cambridge, ‘‘a good year,”’ is evident from the names of the distinguished men of whom he took precedence, such as the following :—Peacock, Dean of Ely ; Fallows, late Astronomer Royal at the Cape; Romilly, late Registrar of the Uni- versity ; Amos, Mill, and other men of note, whose names adorn the Det partments of Science, Theology and Literature. It may be worth while to note the feeling which subsisted among his fellow collegians ; Charles Babbage, the mathematician (lately deceased) who coveted the honor of of Senior Wranglership, but knowing the powers of his antagonist, Her- schel, declined to appear in the Mathematical Tripos, choosing rather to be at the Head of the Poll. On the 27 May, 1813, he was elected Fellow of the Royal Society, and became one of its most active members, receiving in 1821 the Copley medal. At his father’s death he pursued that branch of science calied ‘‘ Observ- ing A stronomy,’’ and about this time he conceived tie desirability of form- ing a Special Society, and was most active in its foundation, the present ‘‘Royal Astronomical Society.”’ A. P. S.—VOL, XII—2B. Field.] 21 8 , [Dee. 1, In 1831, King William, as a tribute to his great scientific services con- ferred on him the honor of knighthood. Sir John Herschel’s researches on the positions of Nebule and clusters of stars, took up many years of his life. Several of the results he pub- lished in conjunction with Mr. (after Sir James) South, for which a re- ward of a gold medal was presented to both Astronomers. Were it not for the sincere love of science, the toil of these proceedings from mid- night to sunrise would not have taken place; for no one can tell the strain on the constitution, the severity of which is gleaned from his observations while discussing the double stars. He remarked : “Should I be fortunate enough to bring this work to a conclusion, I shall then joyfully yield up a subject on which I have bestowed a large portion of my time, and expended much of my health and strength, to others who will, hereafter, by the aid of those masterpieces of workman- ship, which modern art places at their disposal, pursue with comparative ease and convenience an inquiry which has presented to myself difficulties such as at one period had almost compelled me to abandon it, in despair.’’ Tn 1838, Sir John Herschel was awarded the Royal Medal of the Royal Society, for his paper ‘‘ On the Investigation of the Orbits of Revolving Double Stars.”” The Duke of Sussex, President, gave the following graphic account of his labors : “Sir John Herschel has devoted himself, as you well know, for many years at least, as much from filial piety as from inclination, to the exam- ination of those remote regions of the universe into which his illustrious father first penetrated, and which he has transmitted to his son as a he- reditary possession, with which the name of Herschel must be associated for allages. He has subjected the whole sphere of the heavens within his observation, to a repeated and systematic scrutiny. He has determ- ined the position and described the character of the most remarkable of the Nebulaz. He has observed and registered many thousand distances and angles of position of double stars, and has shown, from the compari- son of his own with other observations, that many of them form systems, whose variations of position are subject to invariable laws. He has suc- ceeded by a happy combination of graphical construction with numerical calculations, in determining the relative elements of the orbits which some of them describe round each other, and in forming tables of their motions ; and he has thus demonstrated that the laws of gravitation, which are exhibited as it were, in miniature in our own planetary system, prevail also in the most distant regions of space ; a memorable conclusion justly entitled by the generality of its character to be considered as form- ing an epoch in the history of Astronomy, and presenting one of the most magnificent examples of the simplicity and universality of those fundamental laws of nature, by which their great Author has shown that he is the same to-day and for ever, here and everywhere. ‘That he was not a mere meditative Philosopher, but one of laborious research and of a practical turn, appears from the imposing catalogue of his written works, a few of which I may be pardoned for enumerating: 13 1871.] 219 [ Field. papers on Optics; 28 on Astronomy ; 10, Pure Mathematics, on Geol- ogy ; on Photography ; on Chemistry ; on Natural Philosophy. “The Encyclopedia Britannica boasts of excellent articles on Light and Sound, and Meteorology, now published separately.”’ A Manual of Scientific Enquiry, published by the Admiralty. The Philosophical Transactions contain many of his valuable re- searches, especially those read before the Royal Society, 19 Nov., 1863, which will ever show his energy and perseverance in spite of the infirmi- ties of his advancing age. In fact, turn where you may, light, emanating from Sir John, seems to cast its beams on almost every department of Science. It may not be out of place to give an extract from his work ‘‘ Outlines of Astronomy,’ a book which fills the student’s mind with enraptured interest in the marvels which he reveals in plain and perspicuous lan- guage ; for example: “There is no Science which, more than Astronomy, draws more largely on that intellectual liberality which is ready to adopt whatever is demon- strated, or concede whatever is rendered highly probable, however new and uncommon the points of view may be, in which objects the most fa- miliar may thereby become placed. Almost all the conclusions stand in open and striking contradiction with those of superficial and vulgar ob- servation, and with what appears to every one until he has understood and weighed the proofs to the contrary, the most positive evidence of his senses. Thus, the earth on which he stands, and which has served for ages as the unshaken foundation of the firmest structures, either of art or nature, is divested by the Astronomer, of its attribute of fixity ; and conceived by him as turning swiftly on its centre, and at the same time moying onwards through space with great rapidity. The sun and the moon, which appear, to untaught eyes, round bodies of no very considerable size, become enlarged on his imagination into vast globes : the one approach- ing in magnitude to the earth itself; the other immensely surpassing it. The planets which appear only as stars, somewhat brighter than the rest, are to him spacious, elaborate and habitable worlds; several of them much greater and far more curiously furnished than the earth he inhabits, as there are also others less so; and the stars themselves, properly so- called, which to ordinary apprehension present only lucid sparks or brilliant atoms, are to him suns of various and transcendent glory, ef- fulgent centres of life and light to myriads of unseen worlds. So that, when after dilating his thoughts to comprehend the grandeur of those ideas his calculations have called up, and exhausting his imagination and the powers of his language to devise similes and metaphors illustrative of the immensity of the scale on which his universe is constructed, he shrinks back to his native sphere; he finds it, in comparison, a mere point ; so lost, even in the minute system to which it belongs, as to be invisible and unsuspected from some of its principal and remote members.”’ Without fatiguing the Society, I think the following paragraph on the study of Natural Philosophy, will be its own apology for insertion. Field. ] 220 [Dec, 1, ** Among the most remarkable of the celestial objects, are the revolving double stars, or stars which to the naked eye or to the inferior telescope appear single, but if examined with high magnifying powers are found to consist of two individuals placed almost close together, and which when carefully watched are (many of them) found to revolve in regular elliptic orbits about each other ; and, so far as we have as yet been able to ascer- tain, to obey the same laws which regulate the planetary movements. There is nothing calculated to give a greater idea of the scale on which the siderial heavens are constructed than these beautiful systems. When we see such magnificent bodies united in pairs, undoubtedly by the same bond of mutual gravitation which holds together our own system, and sweeping over their enormous orbits in periods comprehending many centuries, we admit at once that they must be accomplishing ends in creation which will remain for ever unknown to man; and that we have here attained a point in Science where the human intellect is compelled to acknowledge its weakness, and to feel that no conception the wildest imagination can form, will bear the least comparison with the intrinsic greatness of the subject.” j England was not the only spot from which he made his observations. He found it desirable to carry on his investigations at the Cape of Good Hope, and for this far off scene of inquiry he embarked with his family at Portsmouth, 13 Nov., 1833. The course he prescribed to himself seems to have been to restrict his labors almost, if not entirely, to Stellar As- tronomy. Still he didnot omit to make many careful observations of the Nebula of Orion, of the Milky Way and of other heavenly phenomena ; making accurate drawings, which he subsequently published. In May, 1837, an extraordinary spot appeared on the sun’s disc, the marvel of which was much increased when Sir John published his caleu- lation that the ‘crater of this supposed voleano was sufficiently large to allow the globe of the earth to pass in leaving all around a margin of 1000 miles. On his return to England, in 1838, after, as he states, enjoying much happiness, together with the pleasures of good society, his grateful coun- try bestowed upon him the dignity of a Baronetcy. At this time, Photography beginning to attract much public attention, Sir John turned his thoughts to this beautiful art, directing his inquiries chiefly to that point so important to Photographers, the chemical action of solar rays. Of the value attached to Sir John’s scientific attainments we have abundant evidence in the instances in which he was called upon to occupy the place of advisor and councilor. As member of the Board of Visitors of the ‘‘ Royal Observatory,’’? when he was appointed to receive the annual report of its working and efficiency, a member of the ‘‘ Standard Commis- sion”? on the question of the introduction of the ‘‘Metric System of Weights and Measures ;”’ for many years as one of the leading members of the Council of the Royal Society. On the retirement of Davies Gilbert, this venerable Society of savans 1871.] 221 [Field. nearly succeeded in compromising its title, by almost electing the ple- beian philosopher to the dignity of President, in preference to the Royal patron of science and literature, the Duke of Sussex. So keen was the contest that the subject of our memoir lost it only by 8 votes in a meet- ting of 240 members. He was President of the Astronomical Society three times. In 1845, he presided at the British Association for the Ad- vancement of Science at Cambridge. Many learned European societies, beside those of his own country, rejoiced to inscribe his name on their rolls; but to none of them will our American Philosophical Society yield in its admiration, of this great citizen of the tepublic of Literature and Science, as evinced by the bestowal upon him of their diploma of member- ship. In 1842, he was elected Lord Rector of Marischal College, Aber- deen. : The last of his public official positions, previously to his retirement into the quietude of a country life at Collingwood, in Kent, was that of Master of the Mint, to which he was appointed December 16, 1850, and which he retained until Professor Graham’s appointment, Apri 283. 18pdec im this office Sir John was a worthy successor of the great Sir Isaac Newton, who filled that office in the reign of William III. In subsequent times, the Mastership acquired a political character and was conferred generally on members of the Cabinet, which continued until what is known familiarly amongst Mint employés, the Revolution of ’51, by which the old system of. charters, indentures and contracts for the meltings and coinages, being considered antiquated, it was desired by the higher powers to abolish. Naturally, this move caused much alarm and dissatisfaction ; the distastefulness of which was, however, greatly modified by the gentle and considerate manner in which Sir John exercised the authority entrusted to him. The labor and anxiety inseparable from a reconstruction of so import- ant an establishment, much impaired the health of the subject of this memoir. Still his mental vigor did not succumb to bodily infirmity, as daily he was at his post about 11 o’clock, rarely leaving till 5 or 6 p. m., when he might be seen walking out with his portfolio under his arm, filled with papers to consider and revise, as an evening amusement. Among the many alterations made by Sir John, he framed and calcu- lated tables for standarding the various qualities of gold and silver, which superseded those said to have been Sir Isaac Newton’s. He sanctioned the abandonment of ‘ Trial Plates’’ (designated by Sir John “ Fiducial Pieces ”’) which had been prepared from time to time and used for centuries, and presumed to be mathematically of the due proportions of the pure noble metal, but not really so. In lieu of this practice Sir John directed the Queen’s Assay Master to use his best en- deavors to obviate the evil, so that no officer of a foreign mint should be able to question the conventional purity of our British coin as being other than for gold 916.6, and for silver 925. In giving effect to the Master's wishes, the Queen’s Assay “Master worked out the important correction by preparing and introducing chem- 222 [Dee. 1, Field.] ically pure gold and silver, in place of the standard trial plates. The following extract from Sir John’s correspondence may be appropriately introduced here. “The almost mathematical coincidence of the result of the Pyx (about 30 millions) with the legal standard, is the best proof which can be ad- duced of the admirable system of working the assays.”’ As illustrative of the unfailing kindness of this great man towards friends, as well as towards those, who had had the happiness to serve under him, the writer may be pardoned for introducing some of his last utterances contained in a letter, penned only five weeks before his depart- ure to those realms of Light and Truth, amidst the wonders of which, while in the flesh, he loved to live. “T am suffering under an attack of Bronchitis, which has lasted me all the winter, so excessively severe that I can hardly hold the pen, which must excuse the brevity of this, and being now in my 80th year, I can hope for no relief. I shall retain, however, to the last, a pleasing recol- lection of aid and support I received from you during the period of my administration of the Mint, and I know you will believe me ever, my dear sir, yours, most truly, ; | To'H. W. YT. (Signed) J. F. W. HERSCHEL. In his domestic circle, he could unbend to the capacity of the young, in whose amusements he joined with spirit, and considering his advanced years, with wonderful energy. It may be instanced that, only a few years back, the great astronomer condescended to enter cordially into the children’s Christmas gambols, and played in the most animated manner the part of Sir George with the Dragon; habiting himself in a coat of mail, extemporized from various culinary articles. His impromptu dia- logue with his son as ‘‘the Dragon,’’ was said by the elders to be ab- surdly clever. ‘‘The Herschels do everything well’? was a common way of speaking of the philosopher and his family ; so here the Dragon was so life-like, though made only of brown paper with a scarlet cloth tongue, and the knight looked so doughty, that the tableau nearly sent one of the children into convulsions. Sir John F. W. Herschel, Bart., K. H., D.C. L., &c., was born at Slough, near Windsor, 7 March, 1792. He married, in 1829, Margaret Brodie, daughter to the Rev. Dr. Alexander Stewart, by whom he had a family of three sons and nine daughters. One is married to General, the Hon. Alexander Gordon, uncle of the present Lord Aberdeen, and now heir presumptive to that title. His youngest son is an officer in the Royal Bengal Engineers. He is succeeded in the title by his son Mr. William James Herschel, of the Bengal Civil Service, who was born in 1833 and married in 1864, Anne Emma Haldane Hardcastle, daughter of the late Mr. Alfred Hardcastle, of Hatcham, Surrey. Sir John died at his seat, Collingwood, Hawkhurst, Kent, on Thurs- day, the 11th May, 1871, at 10 o’clock a. M., being in his 80th year. He was buried in Westminster Abbey, on Tuesday, the 19th May. His re- 1871.) 223 iField mains were followed by the Presidents and many members of the various learned societies of England, also by the chief men of science in London. The well-known Dean Stanley officiated on the mournful occasion, and on the following Sunday delivered in the Abbey one of his beautiful char- acteristic sermons, which may be found én etenso, in the July number of “Good Words,” p. 453 (a work to which he occasionally contributed some popular papers on the wonders of the Universe). The Dean took his text from the 14th and 15th verses of the 1st chapter of Genesis. “ And God said let there be lights in the firmament of the Heaven to divide the day from the night; and det them be for signs and for seasons and for days and years; and let them be for lights in the firmament of the heaven to give light upon the earth; and it was so.” Glancing at the private sentiments of Sir John, in these days, when there appears to be an increasing antagonism between science and revelation, it is refreshing to remember how frequently in his writings, and in con- versation with some of his friends, strong indications are observable, that the lofty mind of him who was a master in the science of the starry heavens could penetrate into higher regions still, and forget the proud achievements of intellect and science, in the humility of the adoring Christian; a humility which also manifested itself towards man in count- less acts of generous sympathy and consideration. Of him truly it may be said in the language of a poetical tribute to his memory, which has recently appeared in a periodical of the day (‘‘ Good Words’’). ‘+ Seience and learning led his mind, in reverent awe above ; To him the voices of the stars proclaim’d their Maker’s love.” In the above sketch of the scientific, official and personal character of the departed, it will be sufficiently apparent that with numberless other as- sociations of the learned and scientific, in the decease of Sir John Herschel, our Society has to deplore the loss of a member whose name adorned the catalogue, Mr. Dubois offered the following paper upon a qguast Coin, of Copper, affirmed to have been found ata great depth, in Mlinois. The annual reports of the Treasurer and Publication Com- mittee were read and referred. Pending nominations 679 to 682, and new nomination 683 were read; and the meeting was adjourned, 99, Dubois. ] 224 (Dec. 1, ON A QUASI COIN REPORTED FOUND IN A BORING IN ILLINOIS. Read before the American Philosophical Society, Dec. 1, 1871, By Won. E. Dusors. In July last, a letter was received at the Smithsonian Institute, from Mr. Jacob W, Moffit, of Chillicothe, Peoria county, Illinois, enclosing the photograph of a medal or coin, with the following particulars in relation to it: “In August 1870, I took a contract of sinking a tubular well for Mr. Peter Cline, in this county. I had two men employed to assist in the labor, who are cognizant of all the facts connected with the finding of the coin. “The following are the several strata through which we passed. We used a common ground auger, three inch bore : “Soil, 3 feet. Yellow clay, 10 ; blue clay, 44 ; clay, sand, and gravel 4 ; purple clay, 19 ; brown “‘hard pan,” 10; green clay, 8} ; vegetable mould, 2; yellow clay, 24; yellow hard pan, 2; mixed clay, 205. “Here we brought up the coin,on the auger, from a depth of one hundred and twenty-five feet. “Tt has been examined by gentlemen in Chicago and St. Louis, without any result in explaining the mystery of its origin or date. It is my desire that a further investigation be made. I can, if necessary, send affidavits of myself and other parties as to the truth of these statements.” [Signed ] Jacos W. Morrit. It may here be added, that the place is in a great prairie, near the centre of the State, and near the Illinois river ; about 80 miles east of the Mississippi river. Professor Henry having repeatedly referred rare coins to me, took the same course on this occasion, giving leave to communicate the facts to this society, if it was thought proper. An examination of the piece itself was necessary ; and in reply to my request the owner forwarded the same, with further details, to wit : “Tn answer to your questions I must say, that very few wells or shafts in this region have attained a depth of more than 50 or 75 feet, except in the valleys, where occasiondlly we find a well, through sand and gravel drift, at the depth of 100 feet. “The only token of civilization discovered at a similar depth, in this State, was taken from a shaft in Whiteside county, about 20 years ago. The workmen at the depth of 120 feet discovered a large copper ring or ferrule, similar to those used on ship spars at the present time, They also found something fashioned like a boat-hook. «There are numerous instances of relics found at lesser depths. A spear- shaped hatchet, made of iron, was found imbedded in clay at 40 feet ; and stone pipes and pottery have been unearthed at depth varying from 10 to 50 feet in many localities. “No rational estimate has ever been made of the rate of annual earthy deposit. Our prairie land seems to have been built up by a deposit from 1871.] 225 [Dubois. waters whose current set in from the N. W., changing its course only when in contact with some (then) eminence now far below the surface. The soil is seldom over three feet in thickness, usually underlaid by a yel- low hard-pan of two to three feet. Wood is quite common at all depths at which wells have been sunk in blue clay. “Nothing has been found in any of the Western mounds (as far as I am informed) bearing any resemblance in form or character to this coin. ‘‘On taking the coin from the auger, I washed the clay from it with water. It then presented no appearance of corrosion, bearing a dull red hue, such as is common to old copper. However, after a few minutes, exposure to the air, it began to blacken, and in a short time was en- crusted with a dark green, gummy coat, which I allowed to harden, and then removed by friction.’’ : Thus far from Mr. Moiiit. I learn from another source, that Chillicothe is built upon an alluvium of the Illinois river, very sandy, loose, and easily washed away. The river thereabouts is widened into a lake, about one mile and a quarter wide, and twelve miles long. The French pioneers went through that region, about the close of the seventeenth century. Whether the ground on which Chillicothe stands, has been made by the river, to the depth of 125 feet, since the entrance of the whites, is a point on which the residents there, with or without geological instruction, can- not venture an opinion. As to the facts as above stated, there isevery reason to rely upon their accuracy. Ihave to add some remarks on the physical and artistical traits of the coin itself. : ‘ Properly speaking, it is not a coén or medal, since the marks upon it have not been produced by striking, but by engraving or etching; and they are sunken, or intaglio. It is of copper in good condition, in shape polygonal approaching to circular, about one and an eighth inch in diameter ; somewhat pitted by corrosions, and with very rude figures and inscriptions ou both sides. The central image on one side is that of a man, or a child; on the other are two animals, one of them like a wild cat, with conspicuous ears. The legends are plain enough, to any one who can read them; but being somewhere between Arabic and Phono- graphic, without being either, they are sufficiently puzzling. Happily we have members whose knowledge of paleography may throw some light. For myself, I have seen nothing like it. As to the other artistic characters, the metal proves, by a delicate gauge, to be very uniform in thiékness ; more so than could be attained by the beating out of a hammer in savage hands. I therefore feel sure it has passed through a rolling-mill ; and if the ancient Indians had such a con- trivance, it must have been pre-historic. There are other tokens of the machine shop. Any one can see that the piece has been shaped, not with much symmetry, with shears or chisel ; and the sharp edge taken down with a file. Coins or medals were not thus finished in ancient times, but they were in the middle ages, andin A. P. 8.—VOL. XII—2¢. Dubois. ] 226 [Dee. 1, Spanish America down to about 150 years past. (Tapping the edge with a hammer, was also in use): If the figures and characters were made with a tool, it must have been a very rude one, since a ‘‘flat-nosed ” graver would have left a smooth trough, while here it is rough and granular. This would suggest the greater likelihood of etching, were it not inconceivable that so advanced an art should have been practiced long ago on the Western prairies. The mineral acids, used for such work, were nowhere known until about the fourteenth century ; and in Illinois, while we might suppose agua ardiente, we cannot concede aqua fortis, longer ago than one century. On the whole, it has been worked out with a very crude instrument. As to the condition of the piece, and the discolorations; it is well known that copper, exposed to the air, acquires a superficial sub-oxide or dioxide, which protects it from further destruction. Very many ancient copper coins have been turned up by the spade or plough, which with a little cleaning up, look as if just out of the mint. I herewith show a specimen of Tetricus, a Roman usurper of the purple, in France, about A. D. 270; entirely free from corrosion. I also show a more interesting piece, which with many others, was ploughed up in the southern part of England, about 30 years ago. They were all so encrusted as to be illegible, and the owner gave me a choice at haphazard. On removing the coat of mail, and leaving only the mixture of brown and black oxides, it turned out to be a coin of Carausius, who established himself as a Roman Emperor in Britain, A. D., 287; as long before William the Conqueror, as William was before Victoria. This piece is rare and in perfect order, and forms a part of the Mint collection. ; Some ancient coins, especially those with a slight alloy of tin or cala- mine, making them bronze or brass, are beautifully coated and protected with the green carbonate, the same as that which formed on the Illinois piece before cleaning. I herewith show one of these patinated pieces, a coin of Augustus, also from the Mint Cabinet. They may have been in favorable hiding-places, such as cinerary urns, or columbaria. All things considered, I cannot regard this Illinois piece as ancient, nor old, (observing the usual distinction); nor yet recent; because the ‘tooth of time’’ is plainly visible. What the piece was made for, is a part of the inquiry. Not for current money, bevause it would take a long time to make a handful ; more likely a work of amusement, possibly to exercise the antiquarians. But how it got into such a deep place, supposing it a bona fide discovery which I eannot call in question, is a very perplexing point, and I gladly hand over the explanation to any one willing to undertake it. Certainly it seems, in connection with the finding of the copper ring, and other articles of iron and wood, at considerable depths, to form an item in the study of the formation of the superficial strata in that interesting section of our country. : Since the foregoing was written, I am favored with the suggestions (in writing) of Professor Lesley. He suspects that if anything, it is an astrological amulet. There are upon it the signs of Pisces and Leo.

He reads the date 1072, and says that no geologist can accept the statement that a piece of that age could be lying naturally at a depth of 125 feet, under an Illinois prairie. The piece was placed there as a practical joke, though not by the present owner; and is a modern fabrication; perhaps of the sixteenth century; possibly of Hispano-American, or French-American origin. It may have some connection with the journeys of the early French priests or their voyageurs. I would only add, that those views are forcible, but yet they take imposture for granted, and in so doing, leave us in this dilemma; that a curious piece was made many years ago, and held for the purpose of trick, until a deep hole should be made, long afterwards, in which to bury it, and complete the deception. It is also very hard to believe, that an intelligent and experienced operator in this line would allow himself to be sported with by workmen, and take so much pains, far and near, to ascertain what kind of article he had found. Mr. Lesley explained : He considered the integrity, experience and vigilance of the well sinker no guarantee against the surreptitious insertion of the coin. It is impos- sible to prevent a practical joke of that sort when the jester is resolved to have it so. Experience furnishes a thousand proofs of this in our exten- sive oil regions, where all kinds of rubbish have been brought to the sur- face from considerable depths ; nails, anthracite coal, California nuggets, ‘‘butter of antimony,’’ Lake Superior Red hematite iron ore, &e. It looks as if there is a good deal of this sort of thing going on in the west. The copper-ring and boat-hook ‘taken from a shaft at Whitside; at a depth of 120 feet,’ ‘‘the iron spear-shaped hatchet embedded in clay at 40 feet’? mentioned in the paper, are subjects for the same incredulity. The only possible explanation, excluding an imputation of fraud, in the latter case, would presuppose the recent filling up of a hole in the river bed with clay, through which a piece of iron might slowly settle down. The discovery of a circular stone fire-place, with embers, by Mr. Latrobe’s party of engineers in a gravel cut for the road bed of the Balti- more and Ohio R. R., many years ago, at a depth of 50 or 60 feet beneath the surface, is a circumstance belonging to quite a different category. In the present case we have an evident imitation of Mediterranean coins. But the central figures are unmistakably Red Indian in their character. It is either unique of its kind, or one of a very small class. The proba- bilities against a borehole striking such an object are simply infinity to one. The improbabilities of the coin being at or near the surface, and being worked out from the wall of the hole by the friction of the rods, is equally great. There is too much method in the arrangement of the elements of the legend to doubt that the maker had a definite idea to express. A compound oval symbol occupies the right edge on each face, and may have a phallic significance. But the two human figures on one 228 face seem rather to be in conflict than in conjunction. The head dress may represent hair, or may represent the Indian warrior’s feather crest. Professor Trego remarked that he had seen the once famous grave mound relic and the man ‘‘ who discovered’’ and possessed it, and believed it to be fraudulent. He had no faith in such discoveries in the west. Stated Meeting, December 15, 1871. Present, twelve members. Dr. Woop, President, in the chair.

It is covered with a plate of sandstone which is several feet thick ; and, although the pres- sure produced by the Great Downthrow, which runs along at a distance of about half a mile due south of the locality of the mine, has folded the coal bed with the sandrock back upon itself, yet the sandstone of the rock, thus caught in between the walls of the fold of the coal, is perfectly solid and does not show the slightest trace of disturbance. This is a striking, but well-known phenomenon. The coal itself is bent round, and shows sharp tongues, in the fold. | siete] 500 [April 2t,, At (0) the same sandrock is equally folded and unbroken, as the follow- ing diagram (looking in the opposite direction, 7. ¢. east) will explain. Here, also, the bed, which when doubled measures 5 or 6 feet thick, is really but a three-foot bed. There is nothing, in fact, to identify it with the ‘‘Six-foot’’ coal of Wise County. But it may very well be the 6.7 coal at(b) on Middle Cr. Russell Co. Va. It is opened again at (¢) some hundred yards higher up the creek, and ona north dip of 50°. The Confederate army mined it pretty exten- sively. It is here three feet thick, in three benches each a foot thick. The top and bottom benches good, the middle bench bony. Over it are three or four feet of slates, and then comes a one-foot bed of bony coal. The report goes that the miners found these two coal beds close together, down. below ; making thus one very fair fowr-foot coal bed. A diagram on the next page shows the whole exposure in position, All this is not very encouraging for the coal trade. But the same bed has been opened at (d), directly on the crest of the anticlinal, which has. here sunk (running in an easterly direction) to the level of the creek.

The bed must be nearly, or quite, six feet, and yields good coal (as indeed it does at the other openings); but what its constitution may be I do not know. It is probably subdivided into benches of different qualities ; and, no doubt, has some of the slate of the above last section running through it.

Mr. Christian has here opened several beds, one of which is reported to be much over six feet thick. The coal is wagoned to the county-town of Tazewell, Jeffersonville, fifteen or seventeen (15 or 17) miles distant. The following sketch will show how the coal comes out to market—two miles to James Smith’s, on the 3aptist Valley Road (beautifully engineered, at low grades), formerly a turnpike, and still the highway between East K entucky and Middle Vir- ginia; two miles to the Clinch Valley Road ; thirteen miles by either of these two roads to Jeffersonville : tony Ridge (curisrians tuse { MINES soe ea) : TnALb are Creek. : eT a Ld on ESTES rc eek .. a as Smsacay or op IES go heiaree oek Clinch Riper What the character of the Christian Coal is I do not know by personal in-- spection ; but it must come from the same beds, and be essentially similar to the Scott Coals, and also to the Abb’s Valley Coal next to be described. Just east of the Christian Mines runs a limestone valley, along the south side of the Downthrow, in which the waters sink into caverns. Tt is called ‘Sinking Waters.”? Any one familiar with Abb’s Valley (15 miles further east) will see at once, that the formation is the same ; but I will show that Stony Ridge separates the two valleys and that the coal areas which I have been following all the way from Wise County are cut off, or whittled down to a fine point, opposite Jeffersonville. The next cross-section, No. 8, will show how this is done, and also how the Abb’s Valley coal beds are brought down to the present surface by quite a dif- ferent Downthrow from the one we have been tracing thus far, all the way from Guest’s River in Wise County ; a Downthrow bchind and to the north of this one ; as the map in colors will also help to show. The Clinch Valley Downthrow, going east from Indian Creek, catches in its jaws a less and less number of beds and width of coal ground, until at last, on crossing the great road from Jeffersonville north to Tug Fork of Sandy, it holds but the lowest coal bed, standing at a high angle and very little of it left. This is seen on the Section No. 8, marked Captain Frank Peery’s Coal. How far east along this crack this coal can be traced. I do not know ; but nothing of value can be expected from it ; which is a great pity ; for at this point easy access to the back country ends. Fey 505 [ Lesley. To get over into the Abb’s Valley Coal Fields, two mountains must be crossed, or, rather steep stony hills, consisting of all the formations from the coal down to the limestone ; especially Sandrocks X. (Catskill) and IV (Shwangunk) here much diminished in thickness ; which accounts for the comparative lowness of these mountains when compared with the high mountains formed by the increased outcrops of these formations in the Northern States. The deep rapid rocky bed of Mud Fork of Bluestone lies between the two mountains and descends eastward. Where the turnpike crosses it it is 400 feet below the notch in the crest of the first mountain, X (s ¥ 550 feet below the crest itself); and 250 feet below a slight notch in the This crossing of Mud Fork is, by crest of the second mountain, LV. barometer, on a level with the Jeffersonville Court House, and about 100 feet higher than the Clinch. two miles east of Jeffersonville, at the west end of Wolf Creek Valley.

The divide between them is about 14 miles east of the turnpike, at Frank Peery’s, and say 100 feet higher in level.

Stony Ridges from the very nec Lesley. ] 504 [April 21, Abb’s Valley is produced by a great upthrow of the Lower Silurian limestone against the Coal Measures. The turnpike enters it almost at its head, or western end. From the notch in TV through which the road passes, to the Dry-water course in the centre of the valley is a descent (by barometer) of only 110 feet. Westward the valley rapidly fills up, and that is the course to take in locating a railroad from the mines out to Jeffersonville. A feasible route may be obtained, I think, by keeping up Abb’s Valley to and over its divide, and down Cavyitt’s Run to the Clinch, two miles west of Jeffersonville. The cause of the heading up of Abb’s Valley and Mud Fork Valley so suddenly westward, and against what seems to be the main body of the Tug Fork of Sandy Coal Measures, is a most interesting and important affair, which should be investigated. I can only conjecture it. I take it to be likely that the Abb’s Valley Upthrow of limestone starts across the Measures southwestwardly, becoming less and less of an upthrow, and thus swallowing down from the surface first, the Lower Silurian lime- stones of Abb’s Valley, and then the shales and sandstones of the two stony ridges IV and X; and that it finally merges in the Clinch River Upthrow. At all events, such a geology would result in a topography of this sort : The limestone and shale valleys would head up suddenly against a ridge composed of Coal Measures Conglomerate or Sandrocks, My advice is, that no coal-freight railroad line be sought for in the direction taken by the Jefferson and Tug Sandy Turnpike. But, on the contrary, that a line be sought further west, more down the Clinch, viz. : up Cavitt’s Creek. Let the coal beds there be carefully explored, and a line be found across the divides beyond the west line of Abb’s Valley. ABB’S VALLEY COAL. Wifty feet below the summit of the hill, shown in the ‘‘Local Map’’ on the next page, and nearly 150 feet above the coal bed at its base, is a layer of very coarse, gray, friable sandstone, weathering yellow, with- out pebbles. Over it a tree has turned up a coal crop. The coal bed below is, perhaps, the only workable bed of this district. For, after descending, at a slope of one or two (2°) degrees, south 20° east, through the base of the hill, and getting under water level, it seems to turn up suddenly and quite vertically, and to outcrop along the bottom of a little valley. It has been mined a little close to the turnpike (0) and Mr. Smith reports it to be ‘‘as wide as a room.”’ Ten miles east of this, and in a similar position, a coal bed is mined, which I judge to be the same one, and it is called ten (10) feet thick. In the openings at the foot of the hill (at a) it has been merely thrown out from the water of the little Hy Peegits dug coal all through this re- gion, gives its thickness as (5) five feet of coal in 5? of space. A dirt bed, four inches thick, separates the lower bench of very fine coal from the upper and main body of the bed. : BN5 1871.] 505 [Lesley. This coal bed is dug into by the farmers, at several places on the hill- sides of Laurel Fork, from half a mile to several miles north of Smith’s coal, It is called six feet thick. Cochrane says he has dug it on Laurel where it was good seven feet. LOCAL MAP of ABB'S VALLEY CCAL.

[See p. 504.] The coal and the turnpike summit are, therefore, nearly on a level. From these coal outcroppings just back of Abb’s Valley the coal field A. BP. S.—VOL. XII.—3L Lesiey.} 506 {April 21, of West Virginia and Eastern Kentucky extends, without a break, to the Ohio River. And the south edge of this coal field is the north ridge of Abb’s Valley. The coal beds can be opened anywhere in the hills, just north of Abb’s Valley ; and several low windgaps, similar to that at Mr. Smith’s, give the people of the valley access to the coal field. But, as I have said before, the railway line which passes through Tazewell must approach the coal field from the west—not from the south ; around the head of Abb’s Valley, from Cavitt’s Creek. This will also subserve the interests of any railway projected from the Ohio River up Tug Fork of Sandy to Jeffersonville. (N. B.—I do not feel entire confidence in my geology of the sandstone ridges at Smith’s,—the ridges which form the north boundary of Abb’s Valley. They need much more careful study than I could give them.) THE IRON ORES OF IL AND V. The valleys of Tazewell and Russell, in Virginia, being geological, as well as geographical, prolongations of the interior limestone valleys of Pennsylvania, such as the Nittany, Morrison’s Cove, and Kishicoquilis, contain necessarily the same kinds of ore, inthe same formations, and inthe same conditions. I mean that the unbroken ground is at present covered with patches of brown hematite ‘ blossom,’ just as the ground used to -be where our charcoal furnaces stand ; and that the color of the road and field soil is the same as that of our best iron ore banks; the limestone rocks project in the same style, have the same internal composition, and exhibit the same corroded and-dissolved surfaces ; and potholes, caverns, and sitks abound along certain lines of outcrop. All these things are now known to bear an intimate relationship with both the original setting free of the mineral iron from the limerocks, and its subsequent deposit and consolidation. And it seems to be becoming clear to our geologists, that while there are regularly stratified beds and belts of the ore at two or three distinct horizons in the Lower Silurian Limestone Formation, which may be traced for many miles along the strike of the rocks, there are also vast accumulations of this brown hematite ore along anticlinal axes, especially wherever these are fractured ; or degenerate into pure up- throw faults. It stands to reason that such a line of fracture, with a high wall on one side of it, should, in the course of thousands of ages, have collected vast quantities of the peroxidized iron which was being, through all these ages, set free in the slow dissolution of the limestones and the reduction of the whole mass of upheaved country to its present level. To say nothing of the facility afforded by such fissures to the decomposing and recomposing agency of drainage waters. It is along the great upthrow fissures, then, that we are first to seek the iron ore deposits of this section of Virginia. And such a spot was pointed out to me near the mouth of Lick Run, on the hills bordering the north bank of the Clinch River, in Russell County, at section line No. 4 upon the map. Large masses of ‘blossom ” lie scattered about the fields. Similar shows of ore occur in other places. The hills southeast of Jef- 1871. 507 (Lesley. fersonyi lle, just outside the town, show the existence of ore beneath the surface. Great quantities are reported two miles east of the town; and still more abundant exhibitions in the cove of Wolf Creek, behind Buck- horn Ridge, north of the forks of Wolf Creek, and opposite Rocky Gap. Immense shows are reported in Wolf Creek Valley, inside of (or south of) Rocky Gap. I have myself no doubt of the correctness of these reports, so far as surface exhibitions are concerned. And it is an old and good iron mas- ter’s maxim, that where there is plenty of blossom there will be plenty of good ore. The fact is geologically exact. For the blocks of ore on the surface of limestone land (like the masses of white quartz on the surface of a mica slate country) are the undissoluble parts of the original country left behind by the slow and imperceptible mouldering away and removal of the softer material. A downthrow fissure, also, traverses Wolf Creek, at the foot of Clinch Mountain, as shown in the following continuation of section 8, and this fissure brings the No. IV sandrock of the mountain (which surrounds Burke’s Garden) at a dip of 380°, down against the limestone of the val- ley. How far this fissure extends eastward I do not know ; but certainly beyond Rocky Gap.

Others were sunk by Smith & Robinson, Campbell, Taylor & Bowen, Meik and others at other places in the Holston Valley for a length of twenty (20) miles, more orless, and up Cove Creek four or five miles still further east. No attempts were made to get the plaster further on towards Sharon Alum Springs; but there is nothing to intimate its non-existence except the absence of outcrops through the soil, These outcrops naturally exist- ing, or accidentally exposed in farming, or by the railroad cuttings south and west of the village, have alone (as it seems) determined the search after gypsum in the valley. And as the Saltville people alone have any proper machinery for sending it to market, a stop has been put to all exploration elsewhere. Moreoyor, seeing that Capt. Smith struck a copious brine in two of his wells, the opinion early prevailed that the salt and the gypsum were geologically connected. This opinion induced a number of persons to sink in the gypsum outcrops not for gypsum but for salt water. As salt water _ was obtained in no single instance other than Capt. Smith’s two wells, all hope of obtaining brine and making salt elsewhere than at Saltville has been long since abandoned ; and consequently all exploration of the gyp- sum rocks, which had no commercial value to the salt-well borers. It is therefore probable that the limestone wall (the south wall) of the Holston River Downthrow (Upthrow of limestone) will in course of time be discovered to be converted into gypsum at other points besides those specified above ; and that the gross quantity of gypsum existing beneath the surface along this part of the Holston River far exceeds any estimate which [ can make from the gypsum banks already opened. And for the same reason it is probable that the limestone walls of the other Upthrows of the region will be found turned into gypsum, at least in certain places, and in very considerable abundance. The appearance of brine in such quantity and of such strength must be considered as a local phenomenon explainable without reference to the gypsum. Such an explanation may be found in the very curious lake- deposit of the little triangular plain of Saltville; a deposit evidently made in a deep little lake or pond basin filled with red mud saturated . In this mud the salt-water ksalt deposit now rises the with salt-water, gypsum drainings, &c., & has deposited rocksalt, and from this copious discharge of brine which furnishes all the supply needful for the extensive salt works. The salt lies in solid form, mixed and inter-strati- fied with compact red marl or clay, 200 feet below the water-level of the Holston ; and the borings..have gone down (at the Salt Works) 176 feet further without reaching the bottom! On the top of the deposits of salt and mud is a stratum of blue slate more than 100 feet thick. Over the blue slate lie 60 or 80 feet of gypseous clays. The limestone country being cavernous to great depths, and especially along the face of the Down- throw, it is not surprising to notice that the level of water stands the same for ali the wells and shafts sunk at Saltville and rises and falls in sym- 1871.7 513 (Lesley. pathy with the Holston River. This accounts for the inexhaustible supply of liquid. The heaviest pumping has no perceptible effect in lowering the level. In 1853 the salt yield was 300,000 bushels; 50 Ibs. to the bushel, and 6 bush- els to the barrel ; at 50 cents a bushel. Five furnaces were then running 24,000 gallons of brine pumped daily ; 10,000 cords of wood burned yearly. During the Civil War, four wells were pumped night and day for six months, and yielded 1,000,000 bushels of salt during that half year. There were then sixty-nine different ‘‘ blocks of kettles”? going. These kettles, broken and rusty, lie scattered about the valley for six miles, half buried in piles of burnt and broken down walls which represent the various works then in full operation. Some of the salt water was carried in railway tanks nine miles to Glade Spring Station on the Virginia and Tennessee Railroad, and boiled there. At present there are three ‘‘blocks,’’ of 80 kettles each, (5 bushel to a kettle) per 24 hours, making 360,000 bushels per year, of 800 days. Preston’s gypsum banks yielded 2000 tons in 1854; the cost at the mines, in lump, being $3, and in flour $5; eighty miles distant $20. What the yield has been since and what it is now, I do not know. Ope- rations are vigorously carried on at four or five shafts. Plaster is now sold at the mines for $2.50 the ton; at Sharon Alum Springs, 35 miles to the eastward, at $10, in wagons; and is carried forty miles further east for use upon the soil. Its virtues are well known and highly prized. It doubles the grass crop and grain, and greatly improves corn. One bushel of 100 pounds is sown to the acre. A railway from Saltville east would find a market for all the plaster it carried. Plaster would go east to the Wolf Creek Fork Junction, and re- turn by the other line to be used on the pasture lands of Tazewell and Russell and Wise Counties. But its greatest commercial outlet would be towards Staunton and Winchester. Although the gypsum rocks have not the regularity of a coal bed, and some difficulties, of a kind peculiar to this district will be encountered when mining operations are extended to cope with the demands of com- merce along a great trunk railroad, yet I see no practical limit to the eapacity of the gypsum belt for exploration. Shafts five and six hun- dred feet deep have permitted the miners to feel the gypsum masses for fifty yards in width. Such a mass, limited by such a shaft, weighs six or seven hundred thousand tons, provided the gypsum be solid the entire depth of the shaft, &c., &c. This is not the case ; neither, on the other hand, is the width of the column of gypsum limited to fifty yards, or to any other figure. Nothing can be more irregular than the masses of gyp- sum underground—unless it be the course to be taken to get it out to the surface. In spite of all mining difficulties the value and scarcity of the mineral in all other parts of the country must make its mining in this district always extremely profitable, and its railway carriage over long dis- ances inevitable. It must always be in demand; can always pay a high freight charge, and cannot meet with competition from the Nova Scotia plaster until it arrives within a hundred miles or so of tidewater. Westward and southward it may go five hundred miles without meeting competition. 514 Stated Meeting, Sept. 20, 1872. Present, nine members. Vice President, Mr. Frauey, in the Chair.

Second notice of Extinct Vertebrates from Bitter Creek, Wyoming Territory. On the existence of Dinosauria in the Transition beds ot Wyoming Territory. On the Dentition of Metalophodon. The Secretary announced that he had received a telegram from Prof. Cope, dated Black Buttes, Wyoming Territory, August 17th, announcing the discovery of Lefalophodom dicornutus, bifureatus, and excressicornis, Cope. Prof. Edwin J. Houston called the attention of the Society to a remarkable instance of the acoustic sensitiveness of matter. “While visiting a number of water-falls on Adam’s Brook, Pike Co., Pennsylvania, I noticed one in which a scanty supply of water was dripping, in thin delicate streams, from the moss covered walls of a precipice. The day was unusually calm, and the veins were remarkably free from ventral segments for a considerable distance from the fila- ments of moss from which they issued. Struck with this circumstance the idea occurred to me to test the sensitive- ness of the stream to sound pulses. J made the attempt, and after several trials found a note, a shrill falsetto, to which they would respond. The experiment was one of extreme beauty. At one point 516 [Sept. 20, Chase. ] of the falls, there were no less than one hundred of these streams, and on sounding the required note the groupings of the drops and the positions of the ventral segments in- stantly altered in quite a marvellous manner. This case of acoustic sensitiveness is one of the most extensive I have ever noticed. A. second fall was found that would respond to certain notes, though it was not equal to the first in sensitiveness. Though not able, from a sudden flooding of the streams, to discover the exact conditions for success, I believe the explanation of the phenomenon to be the same as that now generally given for sensitive smoke and water jets, viz: that the sound pulses produce a vibration of the orifice of the jet, by which the constitution of its issuing stream is altered. The orifice in the case is replaced by the thin moss filaments, which are surrounded by the stream instead of surrounding it. rom their shape and position their filaments, acting as reeds, readily accept the motion of the sound waves and so alter the constitution of the vein.” Prof. Chase communicated observations on Daily Auroral and Meteoric Means, and on some new correlations of stellar and Planetary distances. Mr. Lesley described a newly observed terminal moraine crossing the Walkill Valley at Ogdensburg near Franklin, Essex county, New Jersey. Pending nominations, Nos. 697 to 701 and new nomina- tion No. 702 were read. The meeting was then adjourned. DAILY AURORAL AND METEORIC MEANS. By Purny Earur Case. (Read before the American Philosophical Society, Sept. 20, 1872.) The apparent influence of meteoric falls upon auroras, which is indi- cated by the five-day means, (ante p. 402), renders more minute observa- tions desirable, in order to ascertain to what extent a similar influence may be traceable in the daily means. The only available observations that have fallen under my notice, from which any satisfactory approximation can be made to the daily meteoric curve, are embodied in Baumhauer’s table of the recurrences of meteoric stones and fire-balls, quoted by Lovering, (‘‘on the Periodicity Sa 1872.] 517 [Chase. of the Aurora Borealis,’’ p. 220). Lovering observes that the days sig- nalized by the frequency of these phenomena are also days which, accord- ing to Quetelet, are distinguished by extraordinary numbers of shooting stars. Ihave grouped the second means of Baumhauer’s numbers in five-day periods, and calculated the ratio of each ordinate to a mean or- dinate of 100, in order to justify the following comparison with the auroral ordinates, which were similarly computed from Lovering’s table. 1 Se Frve-Day AURORAL AND Mrerroric NoRMALS. | (A.—Auroral, Lovering.

(Read before the American Philosophical Society, July 19th and October 18th, 1872.) Although I know of no good reason for admitting that the question, whether the moon exerts an influence upon the weather, is still an open one, there is, undoubtedly, considerable uncertainty as to the value of any predictions that may be based upon such influence, liable, as it is, to local, accidental and variable disturbances, partly of a known and partly of an unknown character. On this account, I think it desirable to collect and discuss all accessible records of observations extending over a period of ten or more years, especially in the neighborhood of sea-coasts and large bodies of water, in order to find how the lunar weather-curves are modified. by the forms of continental relief, the average hygrometric condition of the air, the changes of wind, and other obvious or more obscure sources of perturbation. I am willing to devote all the time I can spare from TABLE I. Different and non-correspondent Rainfalls at San Francisco, in Lunar and Solar periods, from ‘July 1, 1849, to July1, 1872.

About a year ago, I showed, by my discussions of the Lisbon rainfall (ante pp. 178-190), that it is possible, uuder favorable circumstances, to obtain satisfactory evidence of lunar influence upon the weather, even from a comparison of the rainfall in different cycles of less than six years’ average duration. My subsequent discussion of the monthly means of Tennent’s San Francisco observations (Journal of the Franklin Institute, lxiii. 204-6), led me to hazard certain predictions relative to the tidal rains on the opposite shores of continents, and the influence of opposite winds, or of upper and lower tidal currents. Mr. Tennent has gcnerously furnished me a copy of his'daily observations on the rainfall, which so fully corroborate the first and third of those predictions, that I hope to obtain from him an equally complete record of the direction of the wind, in order to have the requisite data for similarly testing the other two. Governor Rawson W. Rawson, C. B., has also kindly con- sented to provide me with a transcript of observations at Barbados, a sta- tion within the belt of the trade winds, and, therefore, favorably situated for such comparisons with the San Francisco observations as may serve TABLE III.

By Epwarp D. Cope. ' (Read before the American Philosophical Society, September 20, 1872.) This discovery of a second species allied to Bathmodon, Cope, repre- sented by more complete remains of dentition than that on which that genus was originally established (B. radians), renders it possible to en- large our knowledge of its characters. It may be premised that the new species may belong to the group Loxolophodon, and, as its characters differ from those of the large species Hobasileus cornutus, furcatus and pressicornis, 1 must retain the last named genus with characters ascribed in my last paper to the former, and withdraw the species from the former, to which I at that time re- ferred them. It appears that this name, used first for a section of ? Bathmodon, was, perhaps, based on mandibular teeth alone, which in Metalophodon, differ remarkably from the maxillaries. The cranium of the new species to be described was so decayed as to be irrecoverable, but the teeth obtained were in place, and in close proximity, so that there can be no reasonable doubt that they belong to the same animal. The species differ considerably from the B. radians. 'The most promi- nent are: first, the failure of the lateral or straight limbs of the ry 1872.] 543 [Cope. crescent of the tooth-crown to meet at the apex, in the molars proper 5 second, the presence of two lobed premolars only, the three lobed found n Bathmodon not being represented in any series. The first character appears to me to be of generic importance, hence the name applied to it at the head of this article. It may yet prove to be Loxolophodon, as no generic character distinguishes the inferior molars of the two. It remains however, to determine whether that name applies to Bathmodon, ora genus different from it, as the present. In the meantime the new species may be called Metalophodon armatus. It is as large as the Indian Rhinoceros, or perhaps larger. The incisors are well developed, those of the premaxillary subequal in size. The crown has a convex cutting edge and flat inner face. The outer face is convex. In some the inner face is more concave, and is bounded by a cingulum next the root. The premolars present a single external crescent of acuminate ontline, and a smaller, more transverse one, within. A cingulum bounds the crown fore and aft, but is wanting at both base and apex of the trian- gular base. Inthe more posterior the crescent is more open, and the crown less transverse. Tho molars present an increase in transverse extent of the external crescent, and the interior one is wanting. In the posterior two the anterior ridge curves round at the apex, but issseparated by a consider- able interruption from the posterior. The latter is shortened, and terminates externally in a conic tubercle, which approaches the outer extremity of the anterior ridge. In the last molar the posterior ridge is shorter, nearly straight, and terminating in a cone at each extremity. The canine is damaged, but was of large size, amounting in one or the other of the jaws to a tusk. The probably superior is compressed, with acute edges. The inner face gently convex, the outer more strongly so, with an acute ridge on its anterior convexity, inclosing an open groove, with the interior cutting edge. This surface of the dentine when exposed has a transversely wrinkled character, but no trace of engine- turning in the fractures. In the mandible, premolar and molar teeth are recognizable; the character of the incisors remaining uncertain. As usual in ungulates, they possess a relatively smaller transverse diameter than do the cor- responding teeth of the maxillary. They change very materially in form from the front to the terminus of the series, and in connection with the superior molars, are very instructive as to the genetic connec- tion of different types of dentition. The pecularity of the premolars consists in the fact that besides the single external crescent exhibited by those of the upper jaw, they have a rudimental second one in the position it should oceupy in correspond- ing teeth of Palwosyops. The inner border of the crown is convex, and extends from apex to apex of the crescents. There are no cingula to these teeth. The rudimental crescent diminishes anteriorly, its angle Oope.] : 544 : [Sept. 20. becoming first obtuse, and then disappearing. Posteriorly the reverse process takes place, and proportions increase. But in the last molars they do not assume the proportions seen in Palwotherium and allied forms. They increase in the elevation of corresponding ridges of the crescents, and decrease in the others, so that the resultant form is nearly like that of Dinothertwm or perhaps Lophiodon. The outer ridge of one crescent appears as a cingulum, which sinks to the base of the crown from the apex. This is rudimentalin the genera just mentioned. The corresponding bounding ridge of the other crescent is reduced to a rudiment extending diagonally across the valley between the remaining crests, as is seen in not a few genera of the Eocene. We have thus an explanation of the heretofore obscure question as to the origin of the crescent-bearing tooth of the Artiodactyles. From the two crested type of Tapirus, the two-angled form developes itself by the growth of the cingulum and diagonal crest just described. This is seen completed in Palwosyops. The elevation of the ridges and deepening of the intervening valleys, would result in the ordinary Ruminant type. The same process increasing transverse crests only, derives the Mastodont from the Tapiroid form, and the deepening of the valleys of this, again results in Hlephas. In comparison with Bathmodon semicinctus, Cope, the crowns of the premolars are of similar size, but considerably less elevated. The measurements cannot be given with exactitude, but are approxi- mately as follows: Superior incisor crown, width. 75 inch; elevation .60 inch. Canine 1.25 inches from apex, inner face .75 inch. Premolar length. 76, width 1.1 inch. Molar length crown 1.1 inch, width 1.25 inch. Inferior premolar, length of crown 1 inch, width .75 inch. Posterior mo- lar, length 1.30 inch, width .9 inch. The crests of the last mentioned are quite elevated, one more than the other; the lower with a strong cingu- Jum at the base, which rises to what is homologous with the base of a tri- angle, or outwards; none on the inner aspect of the base of the crown. The cingula of the superior molars are only anterior and posterior. This large ungulate was found in a stratum below those of the Green River Group of Hayden, or in the lower beds of that series, near Black Buttes, Wyoming. Obtained by the Geological Survey under direction of Dr. F. V. Hayden. In a line of banks or low blufts, immediately below that in which the Metalophodon was found, dermal scutes of a small crocodilian are abun- dant. The discovery of the greater part of a cranium of one of these enables me to point out the existence of a species of Alligator of still smaller size than the smallest of the Caimans at present inhabiting South America, This species, which I call ALLIGATOR HETERODON, possess several peculiarities. The anterior and posterior teeth differ exceedingly in shape ; the former are flattened, sharp-edged, and slightly incurved ; the edges not serrate. Those of the premaxillary bone are subequal in size, while one behind the middle of the maxillary is larger 1872. J 545 [Cope. than the rest. The posterior teeth have short, very obtuse erowns with elliptic fore and aft outline. They resemble some forms seen in Pycnodont fishes, and are closely striate to a line on the apex. The upper surface of the cranium is pitted, the frontal and parietal bones, with large, deep, and closely plaeed concavities. The former is per- fectly plane, and the latter is wide. The squamosal arch is also wide, and the crotaphite foramina are large and open. The dermalscuta are very large for the size of the animal, and were net united by suture. They are keelless, and deeply pitted, with smooth margins. The vertebral centra found with other specimens are round. The codéssified neural arches indicate the adult age of the animal. MEASUREMENTS.

My discussions of lunar-monthly vainfall, (ante, x., 489, 538 ; xii, 208"; xii., 179, 523,) embracing observations in Europe, Asiaand America, near eastern and western shores of oceans, in regions of monsoons and return " trade-winds, near equatorial and polar currents, seem to be sufficiently varied in their character to justify a first approximation to the normal curve for the Northern Temperate Zone. The stations are so well dis- tributed that the influence of local “establishments”? must be, to a great extent, eliminated, and it seems reasonable to presume that the residuals. represent, with some degree of accuracy, the precipitation which is occa- sioned by the lunar modifications of the average atmospheric currents. I.have given equal weight to the normals for each station, but as the Toronto observations cover only nine years, and those at Chiswick are of the same general character as those at Surrey, I give two complete aggre- gates: A., embracing stations 2 to 6 inclusive, and B., 2 to 8 inclusive ; and one partial aggregate, C., for all the stations.

These features all seem so natural and so sim- ply explicable, that I am unable to regard them as other than typical. I regret that Mr. Hennessey’s observations at Mussoorie were commu- nicated only for the days of quarterly change. They appear to indicate a curve still more strikingly similar to that of the solar-hourly rainfall, and the indication is corroborated by their influence on the general aggre- gates, as shown in Aggregate C. It would be possible, even with the data now at my command, to form interesting approximations to the normal lunar curves for each calendar month, but I prefer to wait for observations from a much larger number ot stations, before undertaking any more minute calculations than I have embodied in the accompanying table. Even these normals may be em- ployed in connection with barometric and thermometric normals in the study of weather changes ; provided such allowances are made as are obviously required, for the blending of currents over or near the great Lakes, the Gulf, and the ocean. Such limited use of them as I-have already made, has strengthened my conviction that the day is not far distant when the normal lunar influence will be ranked among the im- portant elements for calculating the disturbances, and the tendencies towards equilibrium, which determine all meteorological fluctuations, and render satisfactory forecasts practicable. Stated Meeting, November 1, 1872. Present, 16 members. Vice-President, Mr. Frauey, in the Chair. The Rev. Mr. Nichols, a newly elected member, was pre- sented to the presiding officer and took his seat. A circular letter in-reference to a new table of logarithms was received from Mr. Ed. Sang, dated No, 2 George strect, Edinborough, Oct. l5th, 1872. A letter was received from Dr. William Elder, addressed to the Curators, dated No. 1824 Mount Vernon Street, Phil- adelphia, Oct. 81st, 1872. On motion the Curators were 560 desired to acknowledge the donation of the Bushrod Wash ington Chair, described in the letter, and to return the thanks of the Society for the same. Letters of acknowledgment were received from the Rhode Island Historical Society, (Proc. 88) and Yale Col- lege Corporation (Proce. 88). Donations for the Library were received from the Revue Politique, and London Nature, the Geological Survey of New Hampshire, Silliman’s Journal, and the Franklin In- stitute. The Committee to which was referred Mr. Lyman’s map and description of the Staley’s Creek Iron Ore District, re- ported in favor of its publication in the Transactions. The report was accepted and the publication ordered. The Committee to which was referred Mr. Gabb’s Memoir on the Geology, &c., of Santo Domingo, reported in favor of its publication in the Transactions. On motion the report was accepted and the publication ordered. The death of Mr. Constant Guillou, at Philadelphia, the 20th ult., was announced by the Secretary. Mr. James desired to place on the minutes that he had duly returned the MSS. letter of Dr. Franklin and the map accompanying Pursh’s MSS., Botanical Journal, which he had been permitted to borrow from the library. Dr. Emerson exhibited one of the bricks of a chimney scattered by lightning in the storm of the 25th ultimo; a chimney belonging to a house in which he was sleeping at the time. Mr. Lesley desired to place on record authentie data re- specting fourteen oil wells sunk by the Brady’s Bend Iron Company, at and near their works, on the Allegheny River; and explained the importanee of facts, so obtained, when comparable, in view of the general inaccessibility of the Sub-carboniferous formations underlying the Oil Regions. A discussion of oil theories and of the history of the oil dis- coveries followed, in which Mr. Lyman, Mr. Gabb, Dr. Le Conte, and other members took part. 561 Mr. Chase offered for publication in the Proceedings a first approximation to a curve of Normal Temperature in the Northern regions of the Continent. Mr. A. H. Smith described his observations of the Sub- alpine botany of the North Shore of Lake Superior, in the Summer of 1871, and of ifs absence in the Lake Nibbegong region, further north, which he had explored in the Summer of 1872; this change of flora he was led to ascribe to the fact that the waters of Lake Superior were much colder than those of Lake Nibbegong. His collection of mosses he had placed in the hands of Mr. James for examination. He described the ascent of the Nibbegong River and the thousand islands in the lake itself, which has scarcely been visited by any observers who could report scientific facts. Mr. Gabb instanced an analogous change of flora from the coast to the interior of the northern part of Lower Cali- fornia. Dr. Le Conte said that he woudl assign a hygro-metric cause for this difference, and added that a similar difference was known to exist between the faune of the coast and the interior as far across as to the banks of the lower Rio Grande; and that the line of distinction was sharp and sudden, being drawn along the summit of the coast range of mountains, a barrier not more than 3000 feet high at the place to which he referred. It was evident that the wet winds of the west flank of this barrier and the dry air of its easteru, which made the change in flora and fauna. Professor Haldeman introduced the topic of the Rhyme- law of the Sonnet in European literature. Tle had made extensive collections of Sonnets and studied their construe- tion for the purpose of discovering a normal rhyme arrange- ment. So far from that, he had already tabulated 600 (six hundred) arrangements of the sonnet with a prospect of adding to his tables more. Pending nominations, Nos. 708 to 707 were read. And the meeting was adjourned. A. P, 8. —VOL. X1t.—38. mee Lesley. ] 562 [ Nov. 1, A Recorp oF FouRTEEN Orn WELLS AT Brapy’s BEND, ARMSTRONG County, PENNSYLVANIA. By. J. P., meumy. (Read before the American Philosophical Society, Phila., Nov, 1st, 1872.) Having recently requested Mr. Persifor Frazer, Assistant Professor of Chemistry in the University of Pennsylvania, to examine for new esti- mates of quantity the coal areas which have escaped erosion, in the country on the two sides of and closely adjoining the Allegheny River, at the remarkable ox-bow bend in its course, 70 miles above Pittsburgh and 60 miles below Oil City ; he brought back with him a MSS. report of ot the wells bored by the company on the river banks and along the beds ot the ravines descending to it from the west. We owe this report to the kindness of Stephen Halbrook, Esq., Superintendent of the Brady’s Bend Tron Works. It is needless to recapitulate the history of the oil discoveries, and the gradual extension of the oil producing districts from Titusville and the line of Oil Creek eastward to the Tidioute district, southeastward to the Clarion, westward to French Creek, and southward via Oil City, Franklin, Parker’s Landing, and Brady’s Bend, to the neighborhood of Butler, where the last discovery excitement is now raging. ‘It is only necessary to refer to my report on the geological grounds for believing the middle Allegheny River districts to be productive oil country, published in the Proceedings of this Society, in 1865.* In that paper I have sufficiently described the locale of the wells now to be described. These records may also be compared with similar records communicated to the Society and published in its Proceedings of April, 1865. The ‘‘ Engineers’ Datum’’ of the following table is an assumed level, one hundred feet lower than a mark made on the Brady’s Bend Iron Com- pany’s warehouse, on the river bank, showing the extreme height réached by the great and disastrous freshet of March 17, 1865.

From the above table, it appears that all the oil-producing wells men- tioned in it get their supply from one stratum lying in an undisturbed and horizontal position, varying in their actual depths below a fixed datum level from 1,118 to 1,066 feet, a difference of only 40 feet. This difference is due to three causes, viz. :—1. The different depths in the sil-besring stratum penetrated by the bottom boring of the wells ; 2. The slight inequalities in the upper surface of the stratum ; 3. And s, both from the northwest and chiefly, to a general slight dip of the ro from the southeast, in towards the centre line or axis of the trough or basin which here crosses the Allegheny River in its northeast-south west eourse ; and also to a still slighter and almost insensible decline of the axis of the basin itself southwestward. The table also confirms what was prover years ago, long before the fact was acknowledged by oil men, namely, that it makes no difference whethe a well is started in the valley bottom or on the hill tops, provided it goes down to the uniform and nearly horizontal oil-bearing sandrock. For some of these wells have their mouths at elevations more than 300 feet greater than others. Some on the river bank, and others high up at the heads of side ravines. The great No. 8 well was commeneed at an eleva- tion (379—96-—) 283 feet higher than those on the river bank whieh yield only from one to three barrels a day. The following table shows the thickness of the third sandroek where it was passed entirely through : No. 2.—No sandrock found and no oil. -Sandrock, 26 feet ; hard fine white sand.

No, 9.—Sandroek, pebble very fine and close, very little gas. No. 10.—Sandrock, 10 feet; pebbles pretty fine, except in one thin streak. No. 11.—To sandrock, no oil, but great gas blow, doubtless from a fissure. No. 12.—Sandrock, 17 feet, all pebbles ; steady flow of oil. No. 13.—Sandrock, 18 feet ; coarse open pebbles; and a fair amount of yas. No. 14.—Sandrock, 18 feet ; large coarse pebbles ; fair amount of gas. Other noteworthy facts are as follows : No. 1 well, on the river bank, one half mile above the rolling mill, begun March, 1865, finished 1 866.

No. 8 well, on Queenstown Run; June 26, 1871—September 22, 1871 - water cased out; first show of cil September 22, and began to fill up very slowly. At 12.35 A. M., September 23, struck a vein of gas and oil which spouted over the top of the derrick, and was fired by the nightlamp hung in the derrick, burning the rigging down. The spouts occured every two minutes. At 9 A. m. the fire was extinguished and the oil began to fill the tank at the rate of 35 barrels an hour, but gradually calmed down to about 60 barrels a day during the first month, and October 22 ceased to flow. Tubeing and sucker rods were then put in, and she began te flow again at the rate of 150 barrels a day. This well has been cleaned out many times to keep her in good rwnning order. Immediately after any one such cleaning she produces from 70 to 90 barrels a day, and gradually falls off to about 20 to 25, when it is anderstood that she again needs cleaning. In fifty weeks she has pro- duced 9,505 barrels. ‘There is not much gas except when flowing. No. 9 well, on. the river opposite Catfish; June 24, 1871—October 24, 1871; water cased out; cost $5,750.

Sand pumped for two days afterwards and found that she filled up with less than a bar. rel of oil per day, and therefore concluded it was useless to tube her. Not much gas at any time. No. 11 well, on river haif mile below the mill; August 24, 1871—June 24, 1872 ; water cased out at 437 feet, Struek very heavy vein of gas at 858 feet. The gas from this well, by calculation, would supply fuel to run the rolling mill and machine shop boilers, being therefore equal to'100 tons of coal per week. The pressure of gas would sometimes lift the tools 20 or 30 feet in the hole, tools weighing 1,700 pounds and repe 3800 pounds. ‘The flow of gas is enormous and continuous.

It is a pity that the above records are so defective. The intervals between the numbers given are in many cases large and not noted, and must not be taken as the thicknesses of the rocks named. There is, however, a positive value in allsuch records, however defective, ~ as may be noted by the recurrence of the red rocks in the above lists. These may define the position of the great red formation of the Paleozoic series No. IX of the Pennsylvania State Survey, the representative of the Old. Red Sandstone of English geologists, and the Catskill Formation of the New York geologists. In Well No. 4 it is noted once only as being struck at 1,126 feet. In Well No. 5 it appears at 750, 805, 826, 930, 972 and 1,026 feet. The thickness of the Conglomerate No. XII is accurately determined in Well 4 at 190 feet, and in Well 5 at 170 feet. The thickness of the Conglomerate No. XI1 in the salt well 45 miles further down the river, as determined (not with entire accuracy) from the Record, published on p. 65, vol. X., of the Proceedings A. P.&., April 1865, is 4944-3843 == 160 feet; or, if the top of XII be placed at the ‘‘White Sand’’ 4404 and all the ‘‘Gray Sandrocks”’ be included down to 666//11, == 220 feet. At Sligo Furnace on the Clarion (p. 68, vol. X.), the Conglomerate No. XII, seems to be only 117 feet thick, soft red slate of XI under it only 3 feet thick, and the red and blue slates of [X lie 786—183 = 603 feet below its base, or 720 feet below its top. The resemblance of this to the record of Weil No. 5, given above, is very observable. Thus, in Well No. 5, the red rocks of IX are first struck at 750—45 — 715 feet beneath the top of the Conglomerate. In the Sligo Well (15 or 20 miles to the northeast of it), the top of the red rocks is 786—66 = 720 feet beneath the top of the Conglomerate. In the Well No. 5, the redrocks are noticed at intervals from 750 to 1026 = 276 feet. In the Sligo Well, the red rocks occupy an interval of only 118 feet. It must be taken into consideration, however, that the lowest red rocks of the well No. 5 may represent not No. IX, but the Red Beds of VIII, described in my report to Professor H. D, Rodgers, in 1841, and pub- lished in his Final Report of the Geology of Pennsylvania, under the 1872.] 569 [Lesley. head of the Geology of the Wellsborough Valley or Tioga River District in Tioga County. To trace the thinning away of these calciferous and ferriferous red beds of VIII (Lower Divonian) on their way towards Ohio, underground, is one of the desiderata of American geology. Other well-boring records are published on pages 227 ff, vol. X, Proc. A. P. §., but most of them are confined to the Coal Measures. Those on p- 288 ff, however, penetrate the Deyvonians to considerable depths and show the red rocks in positions analogous to those described above. In one well, at the head-waters of the Clarion, the mouth of the well being 3870 feet below a coal bed, and also below the bottom of XII, the red rocks of IX (?) occur from 216 to 415 —an interval of 200 feet, which is abont the normal thickness of IX in this zone of its decresence westward, The Manchester (Tioga river) red beds (?) were struck at in- tervals from 925 to 956 = 41 feet, 7. ¢., with an interval of 510 between their top and the bottom of IX. In the Glade Well near Pithole (page 241, vol. X), in the Oil Creek country, the red slates were first struck at 196 and got through at 318, the interval being 122 feet. Some red shale was then struck near the well bottom (abandoned, no oil) at 612, 7. ¢., 294 feet below the bottom of the upper red shales. These also probably represent UX and the Manchester red beds, with a diminished interval due to westing. These red rocks correspond to the Marshall group of Michigan, of Winchell (Proc. A. P.8., vol. XI., p. 74), the Gritstone redrocks above and the Chocolate shales below (the latter just over the Hamilton) in Ohio (Idem, p. 75), and to the Brown shales of the Keokuk group of Indiana. They are very noticeable to the traveller on the railways cross- ing Northern Ohio. Norr.—l have received the following letter of explanation respecting the wells at Brady’s Bend : Sr. Lours, Mo., November 13, 1872. Dear Sir:—The detailed surveys were begun and mostly made under my direction, and the wells Nos. 6, 7, 8 and 9 were located by me. This would be of no interest to you or the public were it not that the location of these wells was the result of a long, carefully pursued, and at least apparently successful investigation into the laws of the distribution of the oil in the ‘‘sandrocks.’’ You had already shown that these rocks existed there and at what depth, and had also shown that the general stratography of the district rendered it reasonably certain that oil would be found there, and this had been confirmed by the results of boring in the case of two of the five wells sunk, I tried to find the law of distribution in its application to narrower limits, so as to decrease to the utmost the risks, and inerease to the utmost the chances in sinking wells. Of the five sunk before I went there, two were productive ; of the four sunk since I left, one is productive; of the four I located, namely, Nos. A. P. 8.—VOL. XII.—3T — meter mop as sea sere ded Lesley. 570 [Nov. 1, 1872. 6, 7, 8 and 9, all are productive. No. 9, which is the least productive of the four, was located under restriction to the Lower Campbell tract. No. 8, the most productive, was the last one I located without restriction. Nos. 6 and 7 were both down before any other well was started in the Whiskey Run or Queenstown Run field. The same principles which guided the locating these wells, led me to advise the Brady’s Bend Iron Company against trying the Upper Campbell tract, and the results of boring there by other parties have confirmed their correctness, and there have been so many confirmations that my confidence in the principles amounts to conviction. In opening the Whiskey Run or Queenstown Run field, I simply fol- lowed the general line of strike from the Armstrong Run field; but in locating individual wells I sought lines and areas of deposition of coarse pebbles in the ‘“‘sandrocks”’ out of broken condition of the ‘‘sandrocks.’’ [ had not so far completed the research into the laws which govern the ‘direction and position of these lines and areas that I felt free to com- municate them when I left the oil country, but hope to push ‘the inves- tigations further hereafter. Meanwhile it may be of some -interest that the above results have followed an effort.pursued by scientific methods to find and apply such laws. Yours, very respectfully, JAMES E.

Mr. Gabb described the results he arrived at in making up a summary from tables of undoubted Miocene fossils, col- lected. by him during three years of exploration in Santo Domingo. These tables double the fauna hitherto de- scribed. Instead of the normal percentage of extinct to recent species according to Lyell’s formulas, it appears that the San Domingo Miocene holds 217 extinct and 97 living forms; these living forms existing on both sides of the present barrier of Central America, on top of which barrier lie Miocene rocks. Mr. Gabb stated that he had just. fin- ished the study of the Miocene Fossil Mollusea, collected during his recent geological examinations in Santo Domingo. He found 217 extinct species, and 97 which he recognized’ as living; 15 of these latter are peculiar to the “Panama Province,” having disappeared from the Caribbean waters since the Miocene period. One or two are found in the Eastern seas only, and others are now living on the opposite side of the Atlantic, or on the Atlantic coasts of North and South America; while still others are closely allied to-spe- ‘ies or belong to genera only living at present in the seas of Australia and Southern Asia. The most interesting feature connected with these fossils, however, is that notwithstanding the proportion of liv- ing to extinet forms is about one-third, yet, from the “ facies” of the collection, from the presence of antique types among the genera, and from the vertebrate remains, such as Car- charodon, Megalodon and other well-known Miocene species, there seems little doubt but that the formation was correctly referred to that age by previous writers, such as J.. Carrick Moore, Etheridge, and Duncan. Lyell established the rule many years ago, that the typi- 572 cal Miocene contains but 17 per cent. and the Pliocene from 35 to 50 per cent. of living species. But that rule, while i: applies perfectly well to the local deposits on which it was based, is too empirical to be followed elsewhere, except in a very general manner and where the other data are in accord. An essential objection to the numerical rule exists in the different values that students place on specific characters. No two writers agree on this subject. Besides, as regions become more thoroughly worked up, discoveries of additional fossils, or the finding of living species, previously known conly as fossils, vary the proportions constantly. The general deductions, therefore, drawn by an experienced palseontolo- gist from large collections, are safer guides than any table of percentages fem, Mus. Comp.

It was very fortunate, since I have had the opportunity of seeing Dr. G. A. Maack, and of learning from him some of his geological results on the late Selfridge Expedition on the Isthmus. Please have the following. note added to my paper, with the permission of the Society : The results of the explorations of Dr. Maack last year, on the Isthmus of Darien, put at rest the question of the late geological origin of the Isthmus. He found three late Tertiary strips extending entirely across, proving three channels at least in the Miocene, and some of the deposits indicate a much later era of elevation. One of these, 10 miles inland from Panama, evidently Post Pliocene, is at least 150 feet above the tide. In a very cursory examination of his fossils I detected the following species, also found in Santo Domingo : Melongena melongena. Murex recurvirostris. Malea ringens. Terebra robusta. Conus pyriformis. Natica sulcata. Jerithium plebium. Turritella. Cypreea exanthemata (v. cervinella). Venus paphia, Jardium Haytense. Pecten papyraceus. Dr. Maack in his report calls the older beds of Panama, Pliocene. They maQ (a9) 5 seem to me nearer in age to the rocks which, in Santo Domingo, I called Miocene, but whatever be their real age, the one fact is well established : The Isthmus was elevated at a period not remote from the age of the great volcanic outflow of the Sierra Nevada.

The Librarian stated that a large number of books and. brochures needed binding; that the book-cases had again become overcrowded by accessions; that certain classes of books were seldom or never referred to; that the catalogue in MS. of the Theological books and pamphlets was nearly finished; and suggested that the book-cases might be re- lieved and a benefit be conferred on learning by depositing the Chemieal, Mineralogical, and Geological books, tempo- rarily, in the new building of the University of Pennsy|- vania. On motion of Mr. Ruschenberger, it was Resolved, That the Committee on the Library be requested to consider the expediency of depositing in the library of the University of Pennsyl- vania certain books now in the library of the Society, which are not much called for ; and in ease they shall deem the same expedient, then to report a plan for carrying the same into effect, which will insure tie use of the books to the members of the Society, and also provide for the safe keep- ing of the books so deposited, and their return to the Society when ealled for.

Mr. Cope desired to place on record an abstract, which he communicated orally, of a paper on the Zoological Divisions of the Earth, as proposed by Slater, Huxley and others, giving his preference to that of Slater, and citing the num- bers of species, ete., already described. Dr. Wilcox exhibited a Japanese Magie Mirror, the prop- erty of E. C. Bittinger, U.S. N., and carrying on its back side the inseription “ Elevation—In the dust.” He read two letters written by Prof. John Tyndall to Mr. Alex. Johnson, in answer to a request for an explanation of the physical phenomena of these mirrors, used in the Buddhist cultus. Prof. Marsh gave a short account of the more remarkable resul's of his explorations in the Rocky Mountains since ce O77 1870, viz.: His discovery of the first American fossil ptero- dactyles, cheiroptera, marsupials, birds with biconcave ver- tebree, monkeys (eocene) of low type, and dinoceria, a new order of horned proboscidians with canine teeth. Prof. Cope dissented from the propriety of at present erecting the proboscidians so discovered into a separate order, merely on the ground of their possessing horns and canines, and gave his reasons. Prof. Marsh also gave an interesting account of Mr. Clarence King’s detection and exposure of the “ Arizona Diamond Fraud,” and his own observations of the locality, which is actually in Colorado, and not in Arizona. Had the fraud not been exposed by the prompt energy of Mr. King before the setting in of the deep snows, great suffering and loss of life and a vast plunder of property would have ensued.
