PLATES VIII., IX. 



(Pages IOC, 107.) 



These plates need no description ; tlioj- require study. As they 

 contain all that could be said to fully understand the subject illus- 

 trated, we have written nothing about the art of "telling the age 

 of horses by examining their teeth." Whoever studies these plates 

 will learn that art. Observe the steady change, year b}' year, as 

 it is mapped out before you. Open the mouth of 3'our horse, and 

 compare its appearance with the illustration of the year correspond- 

 ing to his known age, and so on of all others. Thus you will learn 

 the art and the value of these engraved representations.
