From November 10, 1903, to June 23, 1904, a period of about seven months
and a half, the average daily excretion of nitrogen through the urine
was 6.53 grams. In other words, throughout this long period the average
daily amount of proteid matter metabolized was 40.8 grams, only a
little more than one-third the amount called for by the Voit standard.
Until February, the body-weight gradually fell, but from the early part
of February until the end of the experiment the body-weight remained
practically stationary at 70 kilos. Dr. Mendel, however, from the
necessities of his daily work in the laboratory was compelled to a much
greater degree of physical activity than the subject of the preceding
experiment, and consequently required a larger amount of non-nitrogenous
food than the latter. Further, owing to his greater physical activity and
the necessary variations in this daily activity, it was not so easy at
first to attain equilibrium.
On February 9, a balance experiment of six days was commenced, with a
careful comparison of the nitrogen intake and output. In the accompanying
tables are shown all of the data. By scrutiny of these it will be seen
that Dr. Mendel had adopted essentially a vegetarian diet. During this
period of six days, however, he was not in nitrogen equilibrium,
neither was he strictly in body equilibrium, since there was a distinct
tendency for the body to fall off in weight. In this connection it may
be mentioned that there is always a tendency during a balance experiment
of this character for the subject to eat less than he is ordinarily
accustomed to, owing to the tediousness of weighing every particle of
food consumed. Further, for the same reason, and to avoid excess of
chemical work in the analysis of samples of food, he is inclined to limit
his diet to a few articles and thereby unconsciously restricts his intake
of food, sometimes disastrously so.
