During this experiment the subject eliminated 4,807 grams urine, 
containing 0.464 per cent or 22.29 grams nitrogen. The average nitro- 
gen balance per day was therefore as follows: Income in food 6.37 
grams; outgo in urine 5.57 grams, and in feces 1.57 grams; indicating 
a loss of 0.77 gram nitrogen, corresponding to 4.81 grams protein. 
It appears from the above results that although the subject consid- 
ered this diet pleasing and appetizing he did not partake of the bananas 
and Brazil nuts quite so freely as he did of bananas and almonds in 
the previous combination. There was a constant craving for greater 
variety and especially for cereals and vegetables. The general health 
of the subject continued excellent throughout the experimental period.
