is a function of the protein metabolism possible from the diet. It is worthy of
note that there is very little dysentery, diarrhœa or bowel complaint present
amongst the individuals of these tribes. The stools are well-formed and regular,
and very much a contrast to the semi-fluid excretion of the Bengali.

      We made some observations on the blood of the Bhutias and Nepalese in
Darjeeling jail, but no difference of importance could be detected. Thus the
average of 28 observations gave:—

							Bhutea.	Nepalese.
Hæmoglobin							84%	84%
Red b. Corps							5,360,000	5,280,000
White b. Corps							9,740	9,660

      As these prisoners get the same diet while under confinement in all probability
any racial differences in the composition of the blood would have disappeared.
It was found impossible to get blood from these outside the walls of the jail, so
that differences may exist.

      (3) Investigation on the nutrition of prisoners in Darjeeling jail:

TABLE XXVI.

      (a) In order to obtain some idea of what the level of nitrogenous metabolism
of Bhutias and Nepalese would be on a diet more or less similar to their accustomed
diet, we placed a mixed batch of six prisoners on the following:—

Rice								120 ozs.=20 ozs. per man.
Dal								24 ozs.=   4 ozs.     „
Meat								96 ozs.= 16 ozs.     „
Vegetables								36 ozs.=   6 ozs.     „

      Observed for nine consecutive days.
