With this subject, the total intake of nitrogen for the seven days’
period was 80.302 grams. The output of nitrogen through the urine
amounted to 64.03 grams, while 13.898 grams were passed out through the
fæces, making a total output of 77.928 grams of nitrogen. This shows a
plus balance of 2.374 grams of nitrogen for the seven days, indicating
a gain to the body of 0.339 gram per day. The fuel value of the food
averaged 2809 calories per day, while the daily excretion of metabolized
nitrogen averaged 9.14 grams. This is in close agreement with the average
daily excretion of nitrogen through the urine of this subject for the
last two months of the experiment, viz., 9.00 grams of nitrogen.
