In this seven days’ balance trial, there were taken in with the food
76.674 grams of nitrogen, with an output of 67.47 grams of nitrogen
through the urine and 12.571 grams through the fæces, thus showing a
minus balance of 3.367 grams of nitrogen for the seven days. The fuel
value of the food averaged 2486 calories per day, while the average daily
excretion of metabolized nitrogen amounted to 9.63 grams. Schenker’s
daily nitrogen excretion for the last two months of the experiment
averaged 9.82 grams. Presumably, the slight minus balance of nitrogen
was due to the relatively small fuel value of the food, which doubtless
was not quite sufficient for the body-weight, and the degree of bodily
activity then prevailing.
