During this balance period of seven days, 67.630 grams of nitrogen were taken in with the food, while 49.12 grams of nitrogen were excreted through the urine and 9.528 grams were passed out through the fæces. This means a large plus balance of 8.98 grams of nitrogen for the entire period, showing that the body was being supplied with considerably more proteid than was necessary for the establishment of nitrogen equilibrium. The average daily intake of nitrogen was 9.661 grams, whereas this might have been reduced to 8.4 grams per day with perfect assurance of nitrogen equilibrium being maintained. Further, it is to be noticed that the average daily intake of food for this period had a fuel value of only 2542 calories. The average daily excretion of metabolized nitrogen during the balance period was only 7.01 grams, while the average daily excretion for the last two months of the experiment amounted to 7.43 grams.
