There was an increase in the quantity of urea and urine evolved throughout the 
whole inquiry ; and after each dose of water there was a progressive increase to the 
maximum rate in half or three-quarters of an hour, and then a decrease until the next 
supply of water. The maximum rate after the first and second dose was upwards of 
35 grs., and after the third dose it was 32 grs. per hour. 
The urinary water increased from the basal rate of 2‘8 oz. per hour to the rate of 
21 '6 6z. per hour in one hour; and although it fell at the period of observation following 
the second dose of water, it was renewed, and increased to the maximum rate of 22 ‘2 oz. 
in half an hour after the second dose. It again fell, and subsequently rose after the 
third dose of water, but the rate was not then so high as at the previous maximum 
periods. The period of max im um emission of water was a quarter of an hour later than 
that of urea, except after the third dose, when both coincided. The maximum emission 
was eight times the basis quantity. 
Various fluids only . — Numerous other experiments were made of a similar character 
but with different fluids, and the examinations were made hourly. These are collected 
in the following Table.
