We, therefore, see that a fairly high percentage of the total nitrogen of the diet is
absorbed even though it does contain a large amount of rice. The metabolism
of practically 16 grms. of protein per man daily is very much greater than anything
we found in the Bengali or Behari, and makes very evident the superior type of
diet that these tribes live on. For these six prisoners the nitrogenous
metabolism works out to be 0.284 grm. per kilo of body-weight, over two and a
half times the quantity stated by Chittenden to be more than sufficient to meet the
nitrogenous requirements of the body; yet this diet is not by any means so high in
protein as that to which the well-paid and superior classes of the Nepalese and
Tibetan Bhutias are accustomed. This diet is worth in round numbers about
140 grms. of protein, whereas the dietaries of the Tibetan Bhutias may be taken to
have an average value of 160 grms., with a maximum approaching closely 200
to 220 grms. per man daily.

       (b) In order to determine the degree of nitrogenous metabolism attained
by Bhutias and Nepalese on the ordinary jail diet we placed a mixed batch of six
prisoners on the diet in use in Darjeeling jail.

       This diet appears to vary in the quantities of the different ingredients from
day to day, but it is made up of . . . . Rice, makkai ata, (porridge) dal and
vegetables.

Six prisoners observed over ten consecutive days.
