 in the pasture or stable, providing the molars or 

 grinders perform their proper function. The corner 

 incisors are sometimes regarded as the canine teeth, 

 which, through the process of evolution have grad-

 their side and present all the different characteristics 

 accorded the other incisor teeth. 



There are very few cases where incisor teeth are 

 developed in the upper jaws of cattle. Thus far but 

 one recorded case has come under my observation, 

 and that is related by M. Roche Lubin, who says: 

 "On the I4th of April, 1837, I was requested by M. 

 Bonhome, who lives near Rhodez, to extract a tooth 

 which was growing in the middle of the palate of 

 his young bull. The novelty of the thing made me 

 hasten to comply with his request. The animal be-

 palatine arch. It was situated at the middle of the 

 median line, and was precisely of the same character 

 as that of the usual incisor tooth of the ox." 



The molar teeth of the ox, like those of the horse,
