226 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 T Vart Hog of the Cape, rises up in
