The various mastodons, the hippopotamus and the fossil rhinoceros lived in the same countries, and in the same districts, as the elephants, since their bones are found in the same strata and in the same state. Yet these animals very assuredly no longer exist. Every thing therefore, Cuvier maintains, concurs to induce a belief that the fossil elephant is, like them, an extinct species, although it resembles more than they one of the species at present existing, and that its extinction has been produced by a sudden cause, by the same great catastrophe which destroyed the species of the same epoch.
3. On the Great Mastodon, or Animal of the Ohio.
It appears that the Great Mastodon or Animal of the Ohio, was very like the elephant in its tusks and whole skeleton, the grinders excepted; that it very probably had a proboscis; that its height did not exceed that of the elephant, but that it was a little more elongated, and had limbs somewhat thicker, with a more slender belly. Notwithstanding all these points of resemblance, the peculiar structure of its grinders is sufficient to constitute it of a different genus from the elephant. It further appears, that it fed much in the same manner as the hippopotamus and boar, choosing by preference the roots and other fleshy parts of vegetables; that this sort of food must have drawn it towards the soft and marshy places; that, nevertheless, it was not formed for swimming, and living often in the water like the hippopotamus, but that it was a true land animal. Its bones are much more common in North America than any where else. They are even perhaps exclusively confined to that country. They are better preserved, and fresher, than any other fossil bones known; and, nevertheless, there is not the slightest proof, the smallest authentic testimony, calculated to impress a belief that either in America, or any where else, there is still any living individual, for the various accounts which we have from time to time read in the journals respecting living mastodons, which had been observed in the forests or plains of that vast continent, have never been confirmed, and can only pass for fables.
ON THE CAVES IN WHICH BONES OF CARNIVOROUS ANIMALS OCCUR IN GREAT QUANTITIES.
The extraordinary accumulations of fossil bones in caves and caverns in different districts, especially in those composed of limestone, have for many years engaged the attention of inquirers; and, of late, have afforded many interesting facts to the geologist and zoologist. In England, as will appear from the following details, many different fossil animals have been discovered in limestone caves; but hitherto the caves in Scotland, which will probably be found to contain interesting documents of an ancient population, have not been examined. As the subject is a curious and interesting one, we shall, in the following pages, principally from Cuvier’s great work, lay before our readers a pretty full account of the different caves, especially those that afford bones of carnivorous animals.
Numerous caves, brilliantly decorated with stalactites of every form, succeeding each other to a great depth in the interior of mountains, communicating together by openings so narrow as scarcely to allow a man to enter them crawling, and which are yet found strewed with an enormous quantity of bones of large and small animals, are without dispute among the most remarkable phenomena which the history of fossil remains could present to the contemplation of the geologist, especially when we reflect that this phenomenon recurs in a great number of places, and over a very extended space of country. These caves have been the object of research of several naturalists, some of whom have well described and figured the bones which they contain; and even before they were explored by the naturalist, they were celebrated among the common people, who, according to their custom, added many imaginary prodigies to the natural wonders which are really observed in them. The bones which they contain were long, under the name of fossil unicorn, an important article of commerce and materia medica, on account of the powerful virtues which were attributed to them; and it is probable that the desire of finding these bones contributed much to the more accurate knowledge of these caves, and even to the discovery of several of them.
The most anciently celebrated is the cave of Bauman, situated in the country of Blankenburg, which belongs to the Duke of Brunswick, to the south of the city of that name, to the east of Elbingerode, and to the north of the village of Rubeland, the nearest inhabited place, in a hill which forms one of the last declivities of the Hartz toward the east. It has been described by many authors, among whom we shall particularly mention the great Leibnitz, in his Protogæa, pl. i. p. 97, where he gives a map of it, borrowed from the Acta Eruditorum 1702, p. 305.
Its general direction is east and west, but the entrance faces the north. It is very narrow, although it is under a pretty large natural vault. The first cave is the largest. From this to the second, one must descend by another narrow passage, at first by creeping, and afterwards by a ladder. The difference of level is 30 feet. The second cave is the richest in stalactite of all forms. The passage to the third cave is at first the most difficult of all, and we have to climb with hands and feet; but it afterwards enlarges, and the stalactites of its walls are those in which the imagination of the curious has pretended to see the best characterized figures. It has two lateral dilatations, of which the map of the Acta Eruditorum makes the third and fourth caves. At its extremity, we have still to ascend, in order to arrive at the real third cave, which forms a sort of portal. Behrens says, in his Hercynia curiosa, that it cannot be reached, because it would be necessary to descend more than 60 feet; but the above mentioned map, and the description of Von der Hardt, which accompanies it, describe this third cave under the name of the Fifth, and place beyond it a narrow passage, terminated by two small grottoes. Lastly, Silberschlag, in his Geogony, adds, that one of these grottoes leads to a narrow passage, which, descending much, leads under the other caves, and terminates in a place filled with water. There are still many bones in these remote and little frequented parts. Most of those bones which are in collections from this cave, or which have been described, are of the bear genus.
