the incisive bones : in these respects it differs not only from the other 
rhinoceroses, but from all other known animals. The point of the nasal 
bones, instead of terminating in adistinct projection, at acertain distance 
above the incisives, descends, without becoming thinner, before the na- 
sal notches ; and, after being separated in three projecting tubercles, 
becomes united, by a portion which is a little thinner, to the incisive 
bones, where they unite, and form of themselves two other tubercles. 
All these four bones become so consolidated together, that the sutures 
by which they were connected, as well as that which distinguished the 
intermaxillary from the maxillary bones, are not perceptible at only a 
moderately advanced age. This structure, so solid, was doubtlessly 
intended for the support of the horn, and would lead us to suppose, 
that it was more strong, and could be applied with more power in this 
species, than in any of those which now exist. 8. Behind this junction of 
the nasal with the incisive bones begins a bony partition, which separates 
the two nostrils, and passing backwards, is united with the vomer. 
1). In consequence of this partition, the incisive openings are separate 
from each other ; whilst, in the living species, they are formed into 
one large opening. 10. From the length of the nasal notch, the eye 
is placed more backward in this than in the other species. 
With respect to the existence, or the number, of incisive teeth in 
the fossil animal, M. Cuvier observes, that after an infinite number of 
researches, he has not yet obtained any thing certain : he, however, 
thinks he has a right to assert, that the fossil rhinoceros did not possess 
them, at least in the upper jaw. In the lower jaw, M. Pallas, however, 
speaking of a jaw found at Tchikgi, says : In apice maxillce inferioris, 
seu ipso margine, ut ita dicam, incisorio, dentes quidem nulli adsunt ; 
verumtamen apparent vestigia obliterata quatuor, alveolorum minus- 
culorum equidistantium, e quibus exteriores duo obsoletissimi, sed in- 
termedii satis insignibus fossis denotati sunt. Nov. Com. xiii. p. 600. 
Supposing, then, this jaw had actually contained incisors, they, from 
being so very small, must have belonged to a different species from any
