At about the same time, in the same locality, were found other bones and teeth also, differing from those first discovered, and yet equally unlike those of any living animal.  The first evidently belonged to some stout and heavy animal, the others were more slender and of lighter build.  From these fragments, ample evidence to him of his results, he drew the outlines of two animals:  one which he called the Palaeotherium, (old animal,) a figure of which is given in the above wood-cut, and the other Anoplotherium, (animal without fangs).  He presented these figures with an explanatory memoir at the Academy, and announced them as belonging to some creation preceding the present, since no such animals had ever existed in our own geological period.  Such a statement was a revelation to the scientific world:  some looked upon it with suspicion and distrust; others, who knew more of comparative anatomy, hailed it as introducing a new era in science; but it was not till complete specimens were actually found of animals corresponding perfectly to those figured and described by Cuvier, and proving beyond a doubt their actual existence in ancient times, that all united in wonder and admiration at the result obtained by him with such scanty means.

It would seem that the family of Pachyderms was largely represented among the early Mammalia; for, since Cuvier named these species, a number of closely allied forms have been found in deposits belonging to the same epoch.  Of course, the complete specimens are rare; but the fragments of such skeletons occur in abundance, showing that these old-world Pachyderms, resembling the Tapirs more than any other living representatives of the family, were very numerous in the lower Tertiaries.

There is, however, one animal now in existence, forming one of those singular links before alluded to between the present and the past, of which I will say a few words here, though its relation is rather with a later group of Tertiary Pachyderms than with those described by Cuvier.  On the coast of Florida there is an animal of very massive, clumsy build, long considered to be a Cetacean, but now recognized, by some naturalists at least, as belonging to the order of Pachyderms.  In form it resembles the Cetaceans, though it has a fan-shaped tail, instead of the broad flapper of the Whales.  It inhabits fresh waters or shoal waters, and is not so exclusively aquatic as the oceanic Cetaceans.  Its most striking feature is the form of the lower jaw, which is bent downward, with the front teeth hanging from it.  This animal is called the Manatee, or Sea-Cow.  There are three species known to naturalists,—­one in Tampa Bay, one in the Amazon, and one in Africa.  In the Tertiary deposits of Germany there has been found an animal allied in some of its features to those described by Cuvier, but it has the crown of its teeth folded like the Tapir, while the lower jaw is turned down with a long tusk growing from it.  This animal has been called the Dinotherium.  A part of the head, showing the heavy jaws and the formidable tusk, is represented in the subjoined wood-cut.
