FIVE YEARS. 



The horse has, now, a " full mouth." The incisors are all on a 

 level with each other ; although the posterior edges of the corner 

 ones have not yet come into use. The anterior edges of these 

 teeth are slightly worn. The central enamel of the front and 

 middle incisors forms complete rings. The tushes are through the 

 gum. The arches formed by the incisors of both jaws are nearly 

 semi-circular.
