ANATOMY. 



Teeth. — Mares have on each jaw: 6 incisors and 12 molars, 

 or in all 18. Geldings and stallions have, in addition, 2 canines 

 or tushes, making 20 teeth on each jaw. All the incisors and the 

 first three molars are temporary and are replaced. The last three 

 come in as permanent teeth, according to the following table. 



Cattle have 8 incisors on the lower jaw and none on the upper. 

 Their molars are like those of horses in number and the first three 

 are also temporary.

Age of horses by the teeth. — Tell by shedding and appearance of 

 the teeth up to 4 years, according to table. Cups wear out of center pair 

 of incisors of lower jaw at about 6 years; cups wear out of middle 

 pair of incisors at about 7 years; and cups wear out of corner incisors 

 at about 8; cups wear out of center incisors of upper jaw at 8, middle 

 pair at 9, and corner incisors at about 10. Quality of the teeth, kind 

 of food and the way the teeth fit together to be considered. They may 

 wear very unevenly and be very deceptive. The upper incisors are 

 much less reliable as to disappearance of cups than are the lower.
