During this experiment the subject eliminated 4,253 grams urine, 
containing 0.469 per cent or 19.97 grams nitrogen. The average 
nitrogen balance per day was therefore as follows: Income in food 
11.41 grams; outgo in urine 4.94 grams, and in feces 2.29 grams; indi- 
cating a gain of 4.13 grams nitrogen, corresponding to 25.81 grams 
protein. 
The diet of apples, bananas, and almonds was eaten with consider- 
able relish. The subject believed that he could, if necessary, main- 
tain his condition on this diet; but for the sake of variety he felt that 
it would be well to add food made from cereals and relishes, such as 
honey, etc. On such a diet he believed he could perform heavy man- 
ual labor. During the study he exercised a great deal every day, and 
was also occupied with considerable mental work.
