[35] This balance is complicated by the loss of the urine on March 3. Consequently one-seventh of the total nitrogen of the fæces of the period, namely 1.401 grams, was deducted from the total fæcal nitrogen.
[36] This balance is somewhat complicated by the fact that on March 4 the urine was lost, so that this day had to be thrown out. Correction on the fæces, however, was made by deducting one-seventh of the total fæcal nitrogen, on the assumption that the nitrogen-content was essentially the same for each day of the seven-day period.
[37] Hamburg steak contained 52 grams meat, 4 grams fat, 63 grams onions, 111 grams bread, each man eating 230 grams.
[38] One cup, total weight 454 grams, but containing small portions of milk and sugar.
[39] Rice or hominy on being moistened and cooked gains in weight 120 per cent; or rather, after the excess of moisture has evaporated and the rice is fried, it shows a gain of that amount. But for boiled rice or hominy, without drying or frying, there is an increase in weight of 230 per cent, as usually prepared.
[40] In each bowl of soup were 90 grams of oysters, 20 grams of butter, and 190 grams of milk.

[42] This average covers the period from April 13 to May 24 only, as Mr. Bellis was compelled to withdraw from the experiment on the latter date, owing to an accident in the gymnasium.
[43] The fæces of the period were separated as customary by the ingestion of lampblack.
