DENTITION OF HORSES.

These appearances are shown in Fig. 8, which was taken 

 from the mouth of a colt at the completion of the third year. 



During the development of the central permanent incisors 

 in the course of the third year an important change is going 

 on in the first and second molars, the fangs of which are 

 gradually absorbed as the permanent teeth push their way 

 up underneath them. 



FIG. 8. INCISORS OF HORSE AT THREE TEARS. 



At two years and a half old one or two of the permanent 

 molars may be in the mouth. Sometimes the second in po- 

 sition is cut before the first, and a careful examination will 

 show that the crowns of the first and second temporary 

 molars which yet remain are only retained in their position 

 by a slight attachment to the gum, and very little force is 

 required to dislodge them.
