Classification. — Broadly speaking, the milk of all mammals 

 may be divided into classes as under : — 



(1) Milks forming hard curds with rennet. This class includes 

 the milk of the ewe, buffalo, goat, and cow. 



(2) Milks forming a very soft, or no, curd with rennet. In- 

 cluded in this class are human milk, and those of the ass, mare, 

 and mule. 



The composition of milk of all mammals, on the whole, re- 

 sembles that of cow's milk — i.e., they all contain fat in the form 

 of globules, sugar, proteins, and mineral matter. Marked differ- 

 ences, however, occur in the composition of these bodies. 



Comparison of the Fat of Different Animals. — (a) Size 

 of Globules.— The following table (CV.) gives the results obtained 

 by Pizzi : — 



' The milk of the rabbit and mouse contained globules up to 0-0181 ram. in diameter.
