that the teeth* remain the truest criterion by which to judge the 

 age of cattle. 



Fig. 1104 shows the appearance of the teeth in both jaws, as 

 seen from different points of view. 



Fig. 1105 presents a 

 distinct view of the mo- 

 lar teeth on both sides 

 of the upper jaw. The 

 molars of the ox differ 

 from those of the horse 

 in the fact that the three 

 front ones in each jaw 

 are small as compared 

 with the posterior mo- 

 lars. 



The incisors (Fig. 

 1106) are eight in num- 

 ber, and all in the lower jaw. 



It will be seen that the ox has thirty-two teeth, twenty-four of 

 which are molars, arranged as in the jaw of the horse, and eight in- 

 cisors belonging to the, lower jaw. 



The description of the teeth at different periods is givenso con- 

 cisely in the work of our friend, Robert Tennings, V. S. (now of De-
