 the roots of the middle and corner teeth, from an inside view, 

 and I represents the ontside view of the roots. 



By this cnt the pupil will readily understand the anatomical 

 structure of the colt's teeth. These teeth will all disappear from 

 the colt's mouth between the age of two and five years. 



By carefully noticing the ends of the teeth in^ cut No. 2 you 

 will see that the crowns or part that the colt eats with has a hole 

 or mark inside, and by the upper and lower jaw coming in con- 

 tact with each other causing the teeth to wear off at the crown. 

 These cups or marks will disappear at the age of one year from 

 the nippers of the foal. (See cut No. 4.) 



No. i. 

 This is the inside view of a colt's mouth one year old. 

 | [ The middle and corner teeth still retain the cups or marks. 

 When we look for the cups in the colt or horse, always look on 

 the lower jaw, because the lower jaw is movable and the upper is 

 stationary and never moves except when the horse moves his 

 head. 



For this reason there will be more friction on the lower jaw 

 than on the upper, hence the lower teeth will wear away sooner 

 than the upper, and in looking for the marks or cups in the 

 ■crown of the tooth always and invariably look on the lower jaw. 



Cut No. 5 represents the lower jaw of a two-year-old, in which
