THE MILK OF MAMMALS OTHER THAN THE COW. 



milk, and Wroblewski confirms a higher percentage of sulphur. 

 Sikes finds the lime and phosphorus low. Abderhalden, with 

 Schittenhelm and Langstein, find that though biological tests 

 show that the casein of human milk is not the same as that of 

 cow's milk the proportions of amino acids are very similar, and 

 Tangl and Cz6kas confirm this. 



Wroblewski finds that opalisin, a protein not precipitated by 

 acetic acid, until the solution is saturated with salt, and which 

 gives opalescent solutions is abundant in human milk. Camerer 

 and Soldner state that 88 per cent, of the total nitrogen of human 

 milk is protein nitrogen, while Munk gives 91 per cent. 



Bosworth and Gibbin state that when purified the casein 

 of human milk is identical with that of cow's milk. 



Mineral Matter. Harrington and Kinnicutt give the following 

 mean composition of the ash :

The presence of citric acid has been established, and its amount 

 is about 0-1 per cent. 



Bechamp describes a starch-hydrolysing enzyme. The author 

 has established the presence of a proteolysing enzyme analogous 

 to that described by Babcock and Russell in cow's m%. 



The Milk of the Buffalo. This has been examined in Europe 

 by F. Strohmer, W. Fleischmann, A. Pizzi, D'Alzac, Trillat and 

 Forestier, in India by J. W. Leather, and in Egypt by A. Pappel, 

 in conjunction with the author and with G. Hogan. The Egyptian 

 buffalo is called the gamoose.
