Eight years olu the black cavities or marks have 

 disappeared from the corner teeth. (Fig. 9). 



With eight yeai-s the upper and lower corner teeth 

 just meet. 



At nine years old the marks disappear from the 

 upper centre nippers, and also each of the upper 

 corner teeth shows a sharp protrusion at the extreme 

 outer corner. 



At ten years old the marks disapi)car from the 

 next pair of the upper jaw. 



At eleven years old the marks disappear from the 

 corner teeth of the upper jaw. 



The teeth, which up to this age have an oval shape, 

 become broader and rounder, and change, between 

 the 12th and IGtli year, to a iriangiilar shape. From 

 the 10th year, they lose all regular shape, and the 

 age can only be guessed. 



The tushes or tusks in male horses are cut be- 

 ween the 3d and 4th year of age, are conical in shape, 

 somewhat curved and sharp pointed, but are worn 

 down, with the advancing age of the horse, to a more 

 and more rounded form, and finally lose all regular 

 shape. 



Mares generally have no tusks at all, or only 

 faintly visible tushes.
