as from the ordinary flours (see p. 18), and was u.sed in digestion 

 experiments with the same subjects as in the preceding experiments. 

 One experiment was made with each subject. The data of the experi- 

 ments are given in Tables 26 to 28, which follow.

Kind of food. — Milk, and bread made from bran flour. 



Subject. — Man No. 1. Conditions as in experiment No. 469.

Table 26. — Results of digestion experiment No. 487. 



During this experiment the subject eliminated 4,473 grams urine, 

 containing 65.75 grams nitrogen. The average nitrogen balance per 

 day was therefore as follows: Income in food 26.83 grams; outgo in 

 urine 21.92 grams; and in feces 2.23 grams; implying a gain of 2.68 

 grams nitrogen, corresponding to 16.8 grams protein.
