diet (grapes, granose, pears, milk, apples, dried figs, bananas,

 of the nuts would not be far from 85 per cent. 



In the experiments here reported the walnut oil, which was cold 

 pressed from a good grade of nuts, was fed in the usual manner to 

 three healthy young men, and the data obtained are recorded in the 

 following table :
