These teeth appear to have belonged to a first set, as they are small, and the posterior has but three grinding ridges, instead of five, the common number in adult teeth of the lower jaw.
Another portion of the under-jaw, including the symphisis, or chin. In this portion the teeth of one side are every way complete; to wit, the posterior has five transverse ridges, and the anterior three.
A fragment of the upper-jaw with one molar tooth much worn.
Molar teeth which we suppose to be like those of the mammoth or elephant of Siberia. They are essentially different from those of the mammoth or elephant of this country, and although similar in some respects to the teeth of the Asiatic elephant, they agree more completely with the description of the teeth found in Siberia in the arrangement and size of the transverse lamina of enamel. This idea, however, is not derived from actual comparison of the different teeth with each other, for we have no specimens of Siberian teeth in this country; but from inferences deduced from the various accounts and drawings of these teeth to be found in books. A few of these teeth have been found in several places where the bones of the American animal have existed.
An Astragalus.
An Oscalcis.
Os naviculare.
In the large box in which the preceding bones are, is a small one containing a promiscuous mass of small bones, chiefly of the feet.
In the large irregular-shaped box, a tusk of large size. The spiral twist in all the specimens of these tusks which we have seen, was remarked so long ago as the time of Breyneus, in his description of the tusks of the Siberian mammoth in the Philosophical Transactions, if that paper is rightly recollected, for the book is not here to be turned to at present. Many fragments of tusks have been sent from the Ohio, generally resembling portions of such tusks as are brought to us in the course of commerce. But of these spiral tusks, in a tolerable complete state, we have had only four. One was found near the head of the north branch of the Susquehanna. A second possessed by Mr. Peale, was found with the skeleton, near the Hudson. A third is at Monticello, found with the bones of this collection at the Big-bone lick of Ohio, and the fourth is that now sent for the Institute, found at the same place and larger than that at Monticello.
The smallest box contains the horns of the mountain ram, and skin of the fleecy goat.
