MILK - ANALYSIS. 



CHAPTEE I. 



INTRODUCTORY. 



MILK, which, is the secretion of the mammary glands, and 

 constitutes the entire food and drink of the young mammal, 

 is an aqueous solution of caseine, milk-sugar, and small 

 quantities of mineral material, and holds in suspension a 

 quantity of fat in a state of fine subdivision. 



The milk of the cow, to which we will confine our atten- 

 tion in this work, has been analyzed at various times by 

 many chemists. My own analyses, which are among the 

 most recent, are as follows :
