During this experiment the subject eliminated 4,776 grams urine, 
containing 0.607 per cent or 29.02 grams nitrogen. The average 
nitrogen balance per day was therefore as follows: Income in food 
5.68 grams; outgo in urine 7.25 grams, and in feces 1.73 grams; 
indicating a loss of 3.3() grams nitrogen, corresponding to 20.63 grams 
protein. 
From the above results it appears that the diet during this test was 
less sustaining than that used in experiment No. 401. The subject had 
been suffering from a slight laxative condition, which quickly disap- 
peared upon the present diet. The general impression is that fruits 
are more or less of a cure for constipation, but in the case of this sub- 
ject the combination of fruit and nuts had the opposite effect. 
The subject during this test again felt a craving for some kind of 
cereal food, but maintained his usual good health and spirits, notwith- 
standing the loss of body protein. Had the experiment lasted for 
eight or ten da}^s this probably would not have been the case.

During this experiment the subject eliminated 3,209 grams urine, 
containing 0.980 per cent or 31.43 grams nitrogen. The average 
nitrogen balance per day was therefore as follows: Income in food 
7.42 grams; outgo in urine 7.86 grams, and in feces 2.66 grams; indi- 
cating a loss of 3.10 grams, corresponding to 19.38 grams protein.
