AGE OF THE HORSE. 



73 



to show any particular age, but to post the pupil more fully in 

 regard to the shape and form of the teeth at different ages, 

 showing the two extremes, the very young and the very old. 



No. 22. 

 Life-size outside view of a twenty -four-year-old. 



By closely observing the cuts above mentioned, more particu- 

 larly the last four, it will be seen that the five-year-old shows 

 very wide across the crown, while the twenty-four-year-old shows 

 very narrow across the crown, both the inside and outside views. 

 This is caused by what is called the alveolar process. 



It will be more fully understood by the pupil to say, the teeth 

 in the young horse are long, while those in the old horse are 

 short, as shown in Cut No. 18. 



Most people are under the impression that young horses have 

 short teeth, and that old horses have long ones. It is just the 

 reverse. The old horses have the short teeth and the young ones 

 the long, as will be seen in Cut No. 17. A shows the front and B 

 the side view of a full size tooth of a young horse, which averages 

 in length from 2£ to 3 inches. 



While Cut No. 18, lower section, represents the horse when he 

 is very old — three-fourths to one inch long.
