It was found useless to try to get more than 10 ozs. per day of makkai
ata consumed by the prisoners in Buxar jail, so that our maximum quantity of
makkai ata in this series of diets is 10 ozs. per man daily. So far as the
observations go, it will be seen, on comparing them with the similar series carried
out in Bhagalpur jail with country rice, that they bear out what we found there,
viz., that a diet containing up to 10 ozs. per man daily may be taken with advant-
age, and that by increasing the makkai from 8 ozs. to 9.6 ozs. and then to 10 ozs.
for each man daily, we obtain a corresponding gradual increase in the actual
amount of nitrogen undergoing metabolism.
We may, therefore, conclude from the results of the experiments in Buxar
and, as we shall see, also from those in Bhagalpur Central Jail, carried out with a
view to determine the amount of makkai from which the maximum absorption
of protein takes place (the other constituents of the diets being constant), that the
128
quantity laid down in the jail code, i.e., 12 ozs. per man daily is about the maxi-
mum quantity that the average prisoner is capable of consuming ; and that, while
an increase in this amount does seem to be accompanied by a slight increase in the
amount of protein absorbed, the fact that the prisoners cannot consume more than
12 ozs. per day puts any idea of increasing the quantity of makkai ata out of court.
We may now add to our summary the results of these observations, viz., when
makkai ata is substituted for wheat ata in the Behari type of diet.
The general effect of the substitution of 10 ozs. of makkai ata for the same
amount of wheat ata is to place the plane of nitrogenous metabolism of the pri-
soners on a distinctly lower level. On the average for varying quantities of Burma
rice the lowering of the level of nitrogenous metabolism works out at 1.66 grms.
of nitrogen per man daily. This is very clearly brought out by comparing the
curves of the two series of investigations—shown on Charts VI and VII.
Another important fact, which is evident from these results and shown on
the chart, is that the maximum protein absorption takes place from diets—of either
the wheat ata or makkai ata type—in which the 16 ozs. of Burma rice of the jail
diet scale have been reduced to 12 ozs. per man daily.
The optimum quantity of makkai ata for a diet composed of 12 ozs. Burma rice,
6 ozs. dal and 6 ozs. vegetables would appear to be over 10 ozs. and, as we shall see
from the investigations in Bhagalpur jail, probably lies about 12 ozs. per man
daily ; however, this amount is the maximum that the prisoners are capable of eat-
ing, and that only when the rice is reduced to 12 ozs.
We may conclude, therefore, that so far as the observations go—
(1) Burma rice may be reduced to 12 ozs. per man daily in either the wheat
or makkai ata diet.
(2) The 10 ozs. of wheat ata is the correct amount.
(3) 6 ozs. of different dals is probably beyond the amount from which the
maximum absorption can take place, unless the amount of rice is
reduced considerably.

So that from this series of observations we have obtained absolute confirmation
of the facts already brought out in previous investigations, viz., increase of the
quantity of rice (Burma or Country) beyond what we may call the optimum amount
is not only not accompanied by an increase in the degree of protein metabolism,
but actually by a decrease.
By plotting out these figures we obtain a curve which clearly brings out the
effects on protein metabolism of a gradual increase in the quantity of rice from
8 ozs. to 16 ozs. per man daily, when the other constituents of the diet are kept
constant—shown on Chart VIII.
The investigations in this series are of special importance and, from the point
of view of the investigator, most satisfactory for these reasons
:—
(1) The prisoners experimented upon were finely developed healthy men.
(2) They maintained their body-weight without any marked variation one
way or the other.
(3) In every instance the full quantity of rice and all other elements of the
daily diet were consumed. This differs very markedly from
what we found in Buxar where Burma rice was in use. By a com-
parison of the results of the amounts of nitrogenous metabolism
from these different scales of diet we get remarkable results. Thus,
supposing for a moment that exactly the same amount of protein
would be absorbed and undergo metabolism by the prisoners from
the "constant" constituents of the diets, we would get the follow-
ing results regarding the relative variations in the amount of pro-
tein absorbed from different quantities of rice:—
From 16 ozs. of rice= 4.99 grms. N. relatively 9.71 grms.
14 „ „ „= 4.37 „ N. „
10.10 „
12 „ „ „= 3.74 „ N. „
10.49 „
10 „ „ „= 3.12 „ N. „
9.86 „
8 „ „ „= 2.49 , N. „
9.78
„
133
From these results it is at once obvious that
(1) The optimum absorption is obtained in a diet of the above types when
the amount of rice in the diet is about twelve ozs. per day.
(2)
The co-efficient of protein absorption of rice, or indeed of any of these
vegetable food materials, cannot be anything approaching a con-
stant.
(3)
The amount of nitrogen absorbed from the "basal diet" our "con-
stant" is not uniform with varying amounts of rice in the diet, for
example :—
Diet III.
Constant + 3.74 N. from rice, metabolism 10.49 grms.
Diet IV.
Constant + 3.12 N. from rice, metabolism 9.86 grms.
i.e., the co-efficient of protein absorption of rice from these results is just over
100 %.
This is an impossibility and can only be explained by an accompanying increased
absorption from the "basal" or "constant'' part of the diet when the amount of
rice is diminished.
That this increased absorption from the basal or constant part of the diet
has a limit is brought out by a comparison of results of Diets III and V.
Diet III.
Constant + 3.74 N. from rice, metabolism 10.49 grms.
Diet V.
Constant + 2.49 N. from rice, metabolism 9.78 grms.
i.e., the absorptive co-efficient of the protein of rice now works out at about
57 per cent.
'This is explained by the facts already shown. As the quantity of rice—given
with the basal or constant part—is decreased from what we know to be the
optimum amount, the loss to the body of nitrogen is made up by a greater
and greater increase in the absorption of nitrogen from the basal constituents of
the diet, so that after an initial fall the amount of nitrogen absorbed will remain
fairly constant on reduction of rice—up to a certain limit. If this limit be
exceeded, the fall in absorption will again take place.
The proof of this is well seen in a comparison of the results obtained from
Diet IV and Diet V.
134
Diet IV.
Nitrogen of "constant" + nitrogen from 10 ozs. rice gives 9.86 grms. N. metabolism,
Diet V.
Nitrogen of "constant" + nitrogen from 8 ozs. rice gives 9.78 grms. N. metabolism.
Therefore, if the amount of nitrogen absorbed from the constant with vary-
ing quantities of rice were always the same we should have 0.63 grms. of nitrogen
giving an increased absorption of only 0.08 grms. of nitrogen which is absurd.
The explanation is that in Diet V a greater percentage of the nitrogen of both
"constant" and the 8 ozs. of rice is absorbed than in Diet IV.
Taking the diets where the amount of rice is beyond the optimum the reverse
conditions obtain. As the rice is increased in quantity a lower and lower percent-
age of protein absorption takes place both from the "constant" and the varying
quantities of rice. These observations afford further proof, if more evidence is
required, of the impossibility of obtaining any one figure representing the absorptive
co-efficient of the protein of rice, or indeed other cereals of a bulky nature when
cooked, if the quantities of the food-stuffs forming the diets are high; they
further show that the degree of protein absorption depends very largely on the-
total mass of the diet.
We would now draw attention to the very close similarity of the charts
derived from the results in Buxar jail and Bhagalpur jail. In these observations
where the quantities of rice given were similar in amount the charts appear to be
practically identical. The Buxar chart, for reasons already mentioned, is on a
lower scale. We show this comparison on Chart IX.

That is, the maximum protein absorption takes place from a diet containing 10 ozs.
of wheat ata per day, the other constituents of the diet being constant at rice 12 ozs.,
arhar dal 6 ozs., vegetables 6 ozs., while the amount of wheat ata varies in the
different diets from 6 ozs. to 12 ozs. per man daily.
By plotting out these figures we obtain the curve showing the effects on pro-
tein metabolism of this gradual increase in the quantity of wheat ata from 6 ozs.
to 12 ozs. per man per day. This is shown in Chart X.
By contrasting the charts of this series of observations in Buxar and Bhagal-
pur jails—Charts IV and X—it will be seen that the level of nitrogenous meta-
bolism is lower in Buxar jail and that, while the curves do not exactly correspond
with each other, they have much the same features.
The quantity of wheat ata in the Buxar diet which gave the maximum absorp-
tion we found lay between 8 and 10 ozs. and, from the closeness of the figures for
these amounts, we decided it was 9 ozs. In the Bhagalpur diet the chart shows
10 ozs. of wheat ata as giving the maximum absorption, but no observation was
made with 9 ozs. of wheat ata in the diet ; so it is quite possible that the
amounts may be identical for the two jails. At all events, we are justified in
concluding that, with diets of the Behari type, the most advantageous com-
bination appears to be :—
Burma or Country rice

. 12 ozs.
Wheat ata .

. 9 or 10 ozs.
Different dals .
.
.
.
.
. . 6 ozs.

.
.

Both charts agree in showing there is nothing to be gained by increasing the
amount of wheat ata to more than 10 ozs. per man daily.
(iii) Investigation to determine the different degrees of nitrogenous metabolism
on diets composed of country rice, makkai ata, arhar dal and vegetables—all consti-
tuents of the diets, except country rice, remaining constant in quantity.
