The diet of grapes only was so monotonous that it was hardly possi- 
ble to consume the required quantity. To obviate this difficulty a 
small amount of olive oil and some olives and tomatoes were also eaten, 
the total nutrients supplied by these foods being small as compared 
with the grapes. The subject considered this diet quite appetizing. 
During the last two nights of the period, however, sleep was inter- 
mittent and toward morning a hunger was experienced.

During the experiment the subject eliminated 4,229 grams of urine, 
containing 0.152 per cent or 18.77 grams nitrogen. The average 
nitrogen balance per day was therefore as follows: Income in food 
8.50 grams; outgo in urine 4.69 grams, and in feces 1.38 grams; indi- 
cating a gain of 2.16 grams nitrogen, corresponding to 15.38 grams 
protein. 
The subject believed himself to be amply nourished by the above 
diet, and found it more enjoyable at the close than at the commence- 
ment of the test.
