Table 22. — Re.mlt.'^ of digestion experiment Xo. 486 — Continued. 



During thi« experiment the subject eliminated 4:,920 grams urine, 

 containing 57.9!^ grams nitrogen. The average nitrogen bahmce per 

 da}' was therefore as follows: Income in food 15.41 grams; outgo in 

 urine l-t.SO grams; and in feces 1.98 grams, implN-ing a loss of 1.07 

 grams nitrogen, corresponding to 6.7 grams protein. 



SUMMARY OF RESULTS OBTAINED WITH BREAD FROM DIFFER- 

 ENT GRADES OF FLOUR. 



The results of the experiments showing the digestibility of the nutri- 

 ents and availability of the energy of the three grades of flour are 

 summarized in the following tables. Table 23 shows the percentages 

 for the total food (bread and milk) and Table 24 the values computed 

 for bread alone in the manner previously described (p. IS). These 

 latter values are of particular interest.
