3. Mare's milk is thinner than that of the cow, but scarcely so 

 thin as woman's milk. Parmentier and Deyeux did not succeed 

 in obtaining butter from it by churning. But we know from 

 Herodotus that the ancient Scythians made butter from that 

 milk, several centuries before the commencement of the Christ- 

 ian era. Its specific gravity is from 1-045 to 1-035, as deter- 

 mined by Stipriaan, Luiscius, and D. Bondt.-f- The creamed 

 milk coagulates just as cow's milk, but the curd is not so abun- 

 dant. The whey contains sugar of milk, sulphate of lime, and 

 chloride of calcium.^ It readily ferments, and is converted by 

 the Tartars into koumiss.

M. Henri, Senior, in 1830 examined a little milk from the 

 udder of a foal only four days old. Its specific gravity was 1 -002. 

 It threw up no cream ; but when heated, was concreted and di- 

 vided into casein and serum. It yielded,

4. Goafs milk, if we except its consistency, which is greater, 

 does not differ much from cow's milk. It throws up abundance 

 of cream, from which butter is easily extracted. The creamed
