      The average quantity of urine passed per day by these prisoners shows prac-
tically no variation for different quantities of dal, so long as the salt and rice of
the diets do not change, and the climatic conditions are the same.

      Note the very large amount of urine passed by these prisoners even during
the hot months of the year. From the results stated it appears probable that a
casual relationship can be traced between the amount of Burma rice in the diet and
the quantity of urine excreted.

      We have only one set of observations, in which different quantities of country
rice formed part of the diets, other conditions all being identical.

      These observations were carried out in the cold weather in January 1909.
They show a marked fall with a smaller quantity of rice, and also a far less amount
of urine excreted than was the case with prisoners, who were under much the
same climatic conditions, but were given Burma rice to eat.
