 cisors, eight permanent incisors, no temporary molars, and 

 twenty-four permanent ones. The permanent corner incisors 

 appear between ages of four and five years. At five years they 

 are up and in wear. At the age of five the canine teeth appear 

 in the male. Hence at five years of age the horse has a full 

 mouth, possessing twelve molars, four canine teeth, and twenty-

 can mark it down that the horse is at least seven or eight years 

 old. As a rule, the animal reaches the age of nine or ten before 

 the cups leave the central incisors. At ten the cups leave the
