The most remarkable circumstance in this table is the small 

 quantity of milk given by the French cows subjected to experi- 

 ment. It is no uncommon thing for a good Ayrshire cow to 

 give 4 J imperial gallons in 24 hours. The greatest quantity in 

 the above table is 2 '64 gallons : not much more than the half of 

 4^ gallons. 



The milk of the other mammalia, so far as has been examined, 

 consists nearly of the same ingredients as cow's milk ; but there 

 is a great difference in their proportions. 



1. Woman's milk is thinner, more transparent, and much 

 sweeter than cow's milk. When left at rest a cream collects on the 

 surface, which has a whiter colour, and is more transparent than 

 cow's milk cream. The creamed milk is thin, and has rather the 

 appearance of whey with a bluish white colour, than of skimmed 

 milk. 



It was stated by Parmentier and Deyeux, that this cream did 

 not yield butter. But Pleischl showed in 1821, that this was a 

 mistake, and that butter might be obtained from woman's milk as 

 well as from that of the cow.* Indeed Stipriaan, Luiscius, and
