During this experiment the subject eliminated 2,422 grams urine, 
containing 0.497 per cent or 12.03 grams nitrogen. The average 
nitrogen balance per day was therefore as follows: Income in food 
3.51 grams; outgo in urine 4.01 grams, and in feces 0.84 gram; 
indicating a loss of 1.34 grams, corresponding to 8.38 grams protein. 
The subject usually rose at 6.30 and took a cold-water sponge bath, 
followed by gymnastic exercises. He was engaged in literary work, 
though he also exercised about four hours daily in the open air. 
This -diet of bananas became exceedingly monotonous, and the subject 
craved some variation soon after the commencement of the experi- 
ment. The fruit was eaten both raw and cooked, and was most 
pleasing when toasted, with a little salt added. It was noticed that 
when raw bananas were eaten the subject was not hungry as soon as 
when the toasted fruit was eaten. Ordinarily the subject ate but two 
meals a day. but he found that two meals of bananas were not suffi- 
cient to keep him from being hungry all the time. He stated that he 
felt as well at the close of the experiment as at the beginning, except 
that he was hungry for something which bananas did not furnish and 
which he thought nuts or something akin to nuts would supply. He 
did not think that bananas should have all the credit for his continued 
health and good physical condition, since he believed that he could have 
fasted for the three days and still have been strong and well, provided 
be could have had at least eight hours sleep per day.
