By taking observations 23 and 24 together we see that a difference of 2
chittacks of 1st class wheat, equal to 2.142 grms. nitrogen, causes a difference
of 1.7222 grms. in the amount of nitrogen absorbed.
Therefore, this 1st class wheat shows 80.4 per cent. of its nitrogen absorbed.
Other determinations of the absorption of the nitrogen of 1st class wheat
will be given amongst the results obtained from work done on prisoners in
Benares Jail.

Now by taking this result in conjunction with the average of the two
observations given under No. 25 we see that a difference of 1½ chittacks of
wheat, or 1 .458 grms. nitrogen, causes a difference of 12.2345—11.2237
equals 1. 0108 grms. nitrogen in absorption.
Therefore, the ordinary sample of jail wheat shows 69 . 3 per cent. of its

But we know from the observations recorded under Nos. 21 and 22 that
81.6 per cent. of the nitrogen of wheat, arhar and vegetables is absorbed. Sub-
stitute this for the nitrogen of wheat, arhar and vegetables and we get 13.158
× 81.6 equals 10.7369 grms. nitrogen. Therefore 4.111 grms. nitrogen of gram
shows 13.278—10.7369 grms. absorption. Therefore, the nitrogen of gram
shows 61.8 per cent. absorbed.

Nitrogen absorbed—14.553 grms. =77.1 per cent. of nitrogen of diet.
59
Now as before substitute 81.6 per cent. of the nitrogen of the wheat,
arhar and vegetables and we get the amount absorbed from these constituents,.
that is, 14.764 × 81.6 equals 12.0474 grms. nitrogen.
Therefore 4.111 grms. nitrogen of gram shows 14.553— 12.0474 grms.
Therefore 4.111 grms. nitrogen shows 2.5056 grms. absorbed.
Therefore nitrogen of gram shows 60.9 per cent. absorbed.
By taking these last two observations, Nos. 27 and 28, together we see
that a difference of 1½ chittacks of first class wheat, or 1.606 grms. nitrogen,
causes a difference of 14.553—13.278 equals 1.275 grms. in the amount of
nitrogen absorbed.
Therefore nitrogen of first class wheat shows 79.3 per cent. absorption.
Also from No. 27, 4.111 grms. nitrogen of gram shows 2.5411 grms.
absorbed.
And from No. 28, 4.111 grms. nitrogen of gram shows 2.5056 grms.
absorbed.
Therefore 8.222 grms. nitrogen of gram shows 5.0467 grms. absorbed.
Therefore the nitrogen of gram shows 61.38 per cent. absorbed.
(3) The Absorption of the Nitrogen of Arhar Dal and Vegetables.
SERIAL No. 29.
From Nos. 21 and 22 we learned that a diet composed of—
1st class Wheat
.
. 11½ chittacks offering 12.314 grms. nitrogen.
Arhar .
.
. 2 „ „ 3.90 „ „
Vegetables .
. 3 „ „ 0.50 „ „
showed 13.651 grms. of nitrogen absorbed.
By Nos. 23 and 24 we learned that 80.4 per cent. of nitrogen of 1st class
wheat was absorbed.
By Nos. 27 and 28 we learned that 79.3 per cent. of nitrogen of 1st class.
wheat was absorbed.
i.e., from 23 and 24, 2.142 grms. nitrogen showed an absorption of 1.7222 grms. and
from 27 and 28, 1.606 „ „ „ „ „ „ 1.2750 „
therefore 3.748 „ „ „ „ „ „ 2.9972 „
Therefore, the average absorption of the nitrogen of 1st class wheat is as
nearly possible 80 per cent.
Substitute this value for the absorption of the nitrogen of wheat in No.
29 and we obtain the absorption from arhar and vegetables.
60
Thus, 12.314 × 80 equals 13.651—4.4 grms. (Arhar and vegetables).
Therefore, 4.4 grms. (Arhar and vegetables) equals 13.651—9.8512 grms. nitro-
gen=3.7998 grms. nitrogen absorbed.
Therefore, the absorption of the nitrogen from arhar dal and vegetables
works out at 84.1 per cent.
The Absorption of the Nitrogen of First Class Wheat.
SERIAL No. 30.
Nos. 27 and 28 added together give an absorption of 27 . 831 grms. nitrogen
from

23 . 022 grms.
„
„ Gram
8.222 „
„
„ Arhar
3.900 „
„
„ Vegetables 1 . 000 „
Now substitute our average values for the absorption of the nitrogen of
gram, viz., 61.38 per cent., and nitrogen of arhar and vegetables, viz., 84.1 per
cent.
Therefore, the 23.022 grms. nitrogen of wheat equals 27.831—(8.222 ×
61.38+4.90 × 84.1)=27.831—9.1675 grms. absorbed.
Therefore, the nitrogen of 1st class wheat shows an absorption of 81.06
per cent.

Substitute as in No. 30.
Therefore, 20.89 grms. nitrogen of wheat=23.4207—9.1675 grms. absorbed.
Therefore, the nitrogen of ordinary jail wheat shows an absorption of
68.3 per cent.
61
(4) The Absorption of the Nitrogen of Juar.

From serial number 29 we learned that
—
3.748 grms. nitrogen of wheat showed 2.9972 „ „
Therefore
26.770 „ „ „ „ 21.6607 „ „
Therefore, nitrogen of 1st class wheat shows 80.8 per cent. absorbed.

By substituting the values found for the absorption of the nitrogen of first
quality wheat and for arhar and vegetables we get the percentage of the
nitrogen of juar that is absorbed. Thus :
—
5.354 × 80.8+ 4.4 × 84.1 +5.11 juar = 10.72 grms. nitrogen absorbed.
Therefore, the 5.11 grms. nitrogen of juar = 10.72—8.0264 grms.
Therefore, the nitrogen of juar shows 52.7 per cent. absorbed.

Therefore, 5.11 grms. nitrogen of juar=8.9978—6.29569 =2.70211 grms.
Therefore, the nitrogen of juar shows 52.8 per cent. absorbed.

Nitrogen absorbed—12.0354 grms.=77.6 per cent. of nitrogen of diet.
By substituting the same values as in the preceding observations, Nos. 33,
34 and 35, we obtain the percentage of the nitrogen of juar absorbed. Thus :
— 8.566 × 80.8+4.4 × 84.1+2.555 grms. nitrogen of juar = 12.0354 grms.
Therefore, 2.555 grms. nitrogen of juar=12.0354—10.6217 grms. absorbed.
Therefore, the nitrogen of juar shows 55.3 per cent. absorbed.
SERIAL No. 37.
By taking the two observations, Nos. 35 and 36, together we find that a
difference of 2 chittacks of juar causes a difference of
— 12.7484—12.0354=0.7130 grms. in the amount of nitrogen absorbed, i.e.,
1.277 grms. nitrogen of juar shows 0.713 grms. absorbed.
Therefore, the nitrogen of juar shows 55.8 per cent. absorbed.
SERIAL No. 38.
Collating these five observations for the determination of the co-efficient of
the nitrogen absorption of juar we get :—
From No. 33
5 . 11 grms. nitrogen of juar shows 2 . 6936 grms. absorbed.

The Absorption of the Nitrogen of Arhar Dal and Vegetables.
SERIAL NO. 39.
By making use of the four separate observations, Nos. 33, 34, 35 and 36,
for the determination of the nitrogen absorption of juar we can, by introducing
known factors, determine what the absorption of nitrogen is from the other
constituents, Thus :—

Juar, nitrogen

Arhar and Vegetables,

Therefore

=44.5016
Now we know from other results that 80.8 per cent. of nitrogen of this
wheat is absorbed, and we have just shown that on the average 53.95 per cent. of
the nitrogen of juar is absorbed ; therefore, by introducing these known factors,
we can obtain the absorption of the nitrogen of arhar and vegetables—
i.e., 25.698 × 80.8+16.607 × 53.95+17.6 grms. nitrogen of arhar and vegetables
=44.5016
Therefore, 20.76398+8.95947+17.6 grms. nitrogen (arhar + vegetables)
=44.5016.
Therefore, 17.6 grms. nitrogen (arhar + vegetables) = 44.5016—29.72345
grms.
Therefore, the nitrogen of arhar + vegetables shows 84 per cent. absorbed,
a result agreeing with that already obtained from other observations.

Nitrogen absorbed—11.5878 grms. = 69.6 per cent. of nitrogen of diet.
But we have seen that ordinary jail wheat shows 69 per cent. of its nitrogen
absorbed, and arhar + vegetables show 84.0 per cent. absorbed.
Therefore, 7.7728 × 69 + 4.47 grms. nitrogen of barley + 4.4 × 84=11.5878.
Therefore, 4.47 grms. nitrogen of barley show 11.5878—9.0592 grms.
Therefore, the nitrogen of barley shows 56.5 per cent. absorption.

Now introduce the same factors as in No. 40 for the absorption of the
nitrogen of wheat and arhar dal plus vegetables, and we get 7.7728 × 69+2.98
grms. nitrogen barley +4 .4 × 84=10.7558 grms.
Therefore, 2 . 98 grms. nitrogen of barley =10 . 7558 — 9.0592 grms. nitrogen
absorbed.
Therefore, the nitrogen of barley shows 56 . 9 per cent. absorbed.
SERIAL No. 42.
By taking these two observations, Nos. 40 and 41, together we find that an
increase of 2 chittacks of barley causes an increase in the amount of nitrogen
absorbed of—
11.5878 —10 . 7558 =0 .8320 grms.
i.e., a difference of 1.49 grms. nitrogen of barley causes a difference of
—0.832 grms. in absorption.
Therefore, the nitrogen of barley shows 55 . 8 per cent. absorbed.
SERIAL NO. 43.
We may collate these three results for the determination of the absorption
of the nitrogen of barley. Thus :—
No. 40
. 4.47 grms. nitrogen of barley showed 2.5286 grms. absorbed.

Therefore, the nitrogen of barley shows 565.5 per cent. absorbed.

As we know the co-efficient of nitrogen absorption of wheat and arhar
dal plus vegetables, by substitution we can find that of bajra. Thus :—
8.566 × 80.8+4.764 grms. nitrogen of bajra +4.4 × 84=12.9644 grms.
Therefore, 4.764 grms. nitrogen of bajra=12.9644—10.16173 grms.
Therefore, the nitrogen of bajra shows 49.2 per cent. absorbed.
