On the Composition of Goats' Milk. 
as regards the percentage of fat. Thus in the case of these nine 
samples one sample contained as little as 2 per cent, of fat, in 
round numbers, and another as much as 12| per cent. Generally 
speaking, ewes' milk, on an average, is richer in fat than cows' 
milk. 
The sample marked No. 9 can hardly be called milk. It 
was quite yellow and thick, and was, in fact, not perfect milk, 
but the liquid called " colostrum," which first passes from the 
ewe before the regular flow of milk sets in. It will be noticed 
that ewes' colostrum is extremely rich in caseine and com- 
paratively poor in fat.
