manent corner incisors appear 

 in both jaws and are up and 

 ready for use at five years of 

 age. At five years of age the 

 horse has a full mouth of per- 

 manent teeth. The center in- 

 cisors show much wear and 

 have changed slightly in 

 shape, having become rounder 

 on the inside, the cups being 

 about two-thirds gone. The 

 intermediates show wear and 

 the cups are about one-third 

 gone. (Fig. 36.) 



Six years old. — The cups in 

 the center pair of incisors, in 

 the lower jaw, have disap- 

 peared, or nearly so; they 

 have become much reduced in 

 the intermediates and show 

 one year's wear in the corner 

 incisors. (Fig. 37.) 



Seven years old.— The cups 

 in the intermediate pair of in- 

 cisors in the lower jaw have 

 disappeared, or nearly so ; and 

 have become very shallow in 

 the corner teeth. There is a 

 notch in the upper corner in- 

 cisor where it overlaps the 

 lower one. The teeth show 

 marked changes in shape, 

 having become thicker and 

 rounder from the inside, and 

 meet at a sharper angle.
