CHAPTER V.

Some side-issues of the investigation.

1. The relationship, if any, that exists between the amount of urine passed and
the quantity of rice in the diet.

A comparison of the urine excreted on different amounts of rice in the diets is
only given when the conditions that obtained were, as far as possible, the same.
The observations were carried out at the same time of the year when, the tempera-
ture, humidity, etc., were fairly constant. The quantity of the salt given in the
diet was always identical.

(a) PRESIDENCY JAIL, CALCUTTA.
(i).—Five prisoners under observation for seventeen days.
1st period of five days.		Per man daily.	Remarks.
DIET—
Burma rice	26 ozs.	Urine 1760 c.c.	Salt in diet a little higher than usual.
Mung dal	6 „
2nd period of six days.
DIET—
Burma rice	16 ozs.	Urine 1573 c.c.	Ditto.
Mung dal	8.4 „
3rd period of six days.
DIET—
Burma rice	32 ozs.	Urine 1958 c.c.	Salt usual quantity.
Mung dal	4 „

These three results were obtained in August 1908, when the humidity was high and
the variations of temperature and humidity small. If we neglect the action of
the dal they would appear to show a relationship between the quantity of rice
and the amount of urine excreted.

(ii).—Five Bengali prisoners under observation for twenty-two days.
1st period of twelve days.			Per man daily.	Remarks.
DIET—
Burma rice	24	ozs.	Urine 1726 c.c.	Salt usual quantity.
Mottar and Massur dals	6	„	Urine 1726 c.c.	Salt usual quantity.
2nd period of ten days.
DIET—
Burma rice	20	ozs.	Urine 1632 c.c.	Ditto.
Mottar and Massur dals	6	„	Urine 1632 c.c.	Ditto.
