JELIANS’ WART-HOG. 
anterior ones, which are simple teeth, with enamel 
crowns, bodies, and real roots ; and we must take 
another for the posterior large ones, which are 
compound teeth, ( dents composees ,) without roots. 
This remarkable fact, the co-existence of two 
different types of formation for the back teeth 
of one and the same animal, will assume even a 
greater importance from an exact examination of 
the vessels and nerves which conduct to the diffe- 
rent teeth ; and we wish to direct the attention of 
naturalists to this subject, because we think that 
it will be an easier matter to procure subjects fit 
for such an inquiry from the Cape, than from 
Abyssinia. 
But besides the existence of the incisors in the 
intermaxillary bone of our Wart Hog, and the 
absence of these incisors in the species of the 
Cape, we would now give some farther marks of 
distinction in the skulls of both, which, from their 
constant character, are available for the specific 
determination of the animal. 
If a line be drawn from the hind part of the 
head, as far as the most prominent part of the 
nasal bone, we shall find between the two points 
(in the case of the Wart Hog we are describing) 
a sinus, the depression of which falls in the 
middle of the line, where it declines nine inches 
from the plain. Now, this very spot, in the 
case of the Wart Hog of the Cape, rises up in
