During this experiment the subject eliminated 7,317.4 grams mine, 

 containing 87. OS grams nitrogen. The total nitrogen balance per day 

 was therefore as follows: Income in food, 26.09 grams; outgo in urine, 

 21.77 grams, and in feces, 1.1J» grams, implying a gain of 3.13 grams 

 nitrogen, corresponding to 19.6 grams protein.

Table 25. — Results of digestion experiment No. 316. 



oCalculated according to the assumption that 90 per cent of the fat in the bread is digestible. 



During this experiment the subject eliminated 6,556.6 grams urine, 

 containing 92.45 gram.s nitrogen. The total nitrogen balance per day 

 was therefore as follows: Income in food, 26.81 grams; outgo in urine, 

 23.11 grams, and in feces, 1.05 grams, implying a gain of 2.65 grams, 

 nitrogen, corresponding to 16.6 grams protein.
