underneath. In the dairy cow that same pliability of 

 the skin, which must be somewhat thinner than in the 

 beef type, is desired. In sheep the color affords the 

 best indication, a pink color being much approved of by 

 shepherds. 



Hair grows from the hair follicles, which are a folding 

 in of the epidermis to form deep narrow depressions; 

 these depressions are well supplied with nutriment, and 

 are lined with cells from which are developed hairs. 

 Hairs are placed obliquely (on the slant), and by means 

 of a little muscle placed close to their roots, are brought 

 into the upright position, the effects of which are seen 

 in boars and dogs when excited, other conditions, such 

 as ill-health, cold, etc., have the same effect. Each hair 

 is enlarged at the enclosed end, and is lodged in a hair 

 follicle. The whiskers or cat hairs seen on the lips of 

 horses and cats are furnished with nerves which render 

 these hairs very sensitive. The term horse hair refers 

 to the hair of the mane, forelock, tail and fetlocks, and 

 in some breeds, notably Shires, to the strong coarse hair 

 at the knee and hock. In the pig the term " bristles" 

 denote hair; in sheep, where it is very fine, long and 

 wavy, it is known as wool; in the mule and ass, the 

 forelock and mane are either lacking or else only partially 

 developed, the hair of the tail in these animals being 

 limited in quantity; in cattle, the development of hair at 

 the end of the tail is known as "the switch." The 

 escutcheon of cows, held by some to be an indication of a 

 cow's milking qualities, is formed by the two-way-direc-
