This first representation shows a 

 correct view of the appearance 

 of the teeth, denoting the age at 

 two years and a half, previous to 

 which age ihey ai'e smooth and 

 unmarked. During this age, the 

 jocky sometimes 'files' 2 or four 

 front teeth hollow in the middle ; 

 but compare them with the upper 

 jaw, etc. 



On rising three years old, the 

 two fore teeth behnv and above, 

 fall out, and are replaced by horse 

 teeth, with the hollow mark in 

 the middle ; they are also larger 

 and darker color than the sucking 

 ing teeth. Some time after,before 

 four years, two more are shed, 

 and larger, browner horse teeth 

 appear, with the black mark — j^)^£ 

 the tushes also put forth, and the 

 horse is full mouthed, as per sec- 

 ond cut in the margin. 



Only the comers now are un- 

 shed colt's teeth, which remain 

 imtil the middle of the 4 th year, 

 when they are displaced by horse- 

 teeth, and their marks just pei-- 

 teptible. At five years, they be- 

 come larger, more strongly mark- ^^^^^J^^ 

 ed, and are grooved on the inside, 

 which denotes the age of five: no 

 deception can be practiced, nor 

 as regai'ds the tushes, which are 

 now curved, ha-s-ing groves inside, 

 which may be felt in the above 

 cut for four or five years, and 

 plainly seen in the annexed cut 

 for a five years old. At five, too, 

 the two front teeth begin to ap- 

 pear worn, principally on the 

 outer edges ; the wearing goes on 

 and at six, the sui-face is level, 

 and the grooves on the comer 

 tcech fill up, and the curve in the 

 tushes is diminished, and seven 

 years, I'epresented by the last cut 

 annexed, the grooves of the tush- 

 es^fill up, and become convex in 

 another year or two.
