Bolton and Revis find that the Ave Lallemand figure has varied 

 from 6-0 to 16-1, and Trimen finds 7-6 to 16-5. 



The melted fat is called ghee in India and samna in Egypt. 



Sugar. In one sample prepared from 'winter milk Pappel 

 and the author found [a] D 48-9, and cupric reducing power 73-8, 

 but a second preparation examined by A. R. Ling and the author 

 was found to correspond in all its properties with milk-sugar ; 

 the author is now of opinion that the results obtained on the sugar 

 from the winter milk were due to the sugar containing an 

 impurity, as he has since found that the method of preparing 

 the sugar with acid mercuric nitrate does not remove all Isevo- 

 rotatory compounds, and it is probable that the sugar is identical 

 with that of cow's milk. 



Proteins. Pappel and the author examined the proteins, and 

 no differences from those of cow's milk were found. 



The Milk ol the Ewe. The following composition is given by 

 different authorities :
