The American journal of science and arts . but evidently a very young animal, as theywere not at all worn ; the whole weighs eight pounds. These teeth haveonly three ridges transverse.

Fourthly : a tooth which was found with thislast, (about two miles from the two first.) It is the third molar of the up-per right jaw of a horse. A drawing of the crown, and oblique view oftwo sides, is given at Fig. 1; the outer side of the tooth is shown at ; the front side at Fig. 3. There are some slight deviations from the common forms of the festoonsof the enamel upon the crown; but differences frequently are found in theforms of these in living horses. From c to d, (Fig. 1.) measures an inchand a quarter; from d iof, (Figs. 1 and 3.) it measures 3| inches, thoughall of the hollow or shelly parts of the roots are gone, which in common. Miscellanies. 203 horses measure | of an inch. This would make the original length ofthe tooth more than four inches. The size of the tooth in other direc-tions was about proportional. Now as these measurements go far overthose for our largest horses, they would seem to indicate a fossil horse largerthan those of the present epoch; whereas Cuvier says that all the bonesof horses seen by him, indicated the former existence of small horses.{OssemensFossiles, 3d edition, Vol. II. pp. 112, 113.) This fossil is ren-dered interesting, as the remains of the horse are but seldom found fossilin America.
