accidental circumstances the investigations had to be dropped after the fourth
day; but, as the results are of importance regarding the minimal proteid intake
necessary for nitrogenous equilibrium, we reproduce them in Table XI.

This table is of interest from another point of view as, we believe, it is the
first time a nitrogen balance sheet has been worked out in India:—

While these observations were not of sufficient duration to provide a com-
plete standard for comparison, they afford very exact information, and it will be
instructive to analyse the results in the light of the knowledge already obtained
from the two hundred observations on students and servants.

The amount of nitrogen metabolised during the four days by No. 1 was
26.90 grms., or an average daily amount of 6.72 grms. His average body-weight
being 61.50 kilos; we find this is equivalent to the metabolism of 0.109 grm.
of nitrogen per kilo. of body-weight. Translating this into terms of proteid it
