38' PROCESS OF TEETIHXG. 



At Y years the mark in the manner which, we 

 have described it^ has worn out in the four cen- 

 tral nippers, and is fast disappearing in the 

 corner teeth; the tush also is beginning to alter 

 — it is rounding, at the point, the edges, and 

 without, and beginning to get round inside. 



At 8 years old the tush is rounded in every 

 way, the mark has disappeared from all the bot- 

 tom nip23ers, and it may almost be said to be out 

 of the mouth. There is nothing remaining in 

 the bottom nippers afterward that can clearly 

 show the age of the horse.
