found, it appears that the two first sorts of teeth may exist in the 
mouth of the animal at the same time ; but that those of the latter sort 
follow the others. M. Cuvier says, perhaps there may have been, in 
the infancy of the animal, a tooth with four points, which would be 
cast early. This he was led to conjecture, from having been informed 
by M. de Beauvois, that in a jaw belonging to Dr. Barton, there ap- 
peared to be the marks of an alveolus before the tooth with six points. 
There can be little doubt but that the teeth succeeded to each other, 
as in the elephant : there never, however, being more in the mouth, 
at once, than two, and at last only one. 
For want of attending to this succession of the teeth, and supposing 
many of these teeth to have existed in the mouth at the same time, 
very erroneous conjectures have been formed respecting the size of 
this animal. Thus Buffon observes, that the square form of these 
enormous grinders prove, that several were in the jaw at the same 
time ; Epoques de la Nature, Notes justif. 9. But, if we suppose 
there were six, or even four, on each side of each jaw, how enormous 
must that head have been, which contained at least sixteen such teeth. 
Reckoning on these fallacious grounds, he concludes, the animal must 
have far exceeded the size of the largest elephants ; whereas, we have 
no proof at present of this animal reaching to twelve feet in height, 
whilst, agreeable to Buffon’ s own account, the Asiatic elephants are 
sometimes fifteen or even sixteen feet high. 
One of the back grinders of this animal, with five pair of points, and 
an odd one at the end, is represented in the frontispiece to this volume. 
This tooth is in remarkably fine preservation, and was for several years 
a part of the collection in this city, which was called Rackstrow’s Mu- 
seum. It is seven inches and a half long, eighteen inches in circum- 
ference round its crown, and it weighs four pounds seven ounces. 
The remains of the under-jaw of this animal show us that, like the 
elephant and morse, it had neither canine nor incisive teeth ; that it 
terminated in the fore part, as in those animals, in a hollowed point,
