Second Nitrogen Balance.

Commencing February 29, a second nitrogen balance was attempted with very different results. This balance period extended through seven days and was characterized by an average daily intake of 9.50 grams of nitrogen, an increase of 1.3 grams of nitrogen per day over the preceding period, together with an average fuel value of the food equal to 2500 calories per day.

The daily diet with its content of nitrogen, etc., is detailed under Oakman. Any variations (only slight ones) from this diet are indicated on the individual balance-sheets, corrections being made in the nitrogen intake.

In all of the men, with one exception, a distinct plus balance is seen, showing that under the conditions of this experiment the men were all storing up nitrogen. The plus balance per day varied from 0.132 gram to 1.231 grams of nitrogen.

The average daily output of nitrogen through the urine for this seven days’ period (Oakman’s case) was 7.24 grams, being 0.28 gram less per day than in the preceding period. Sliney, the one man who failed to show a positive balance, was apparently losing nitrogen at the rate of 0.48 gram per day during this period.

All of the individual data are shown in the accompanying tables of results:
