During this experiment the s 
containing- 0.657 per cent or 
nitrogen balance per day was 
7.41 grams; outgo in urine 5 
indicating a loss of 0.47 pram 
protein. 
The subject was well pleased 
but stated that he would have i 
tables or some ripe, fresh fruit 
abject eliminated 3,431 grams urine, 
22.56 grams nitrogen. The average 
therefore as follows: Income in food 
.64 grams, and in feces 2.24 grams; 
nitrogen, corresponding to 2.94 grams 
with the diet used in this experiment, 
dished occasionally a few green vege- 
i ii addition.
