Drinking-water. As in the earlier experiments the subjects were allowed 

 drinking-water whenever desired with no restriction as to the amounts. The 

 quantities consumed were not accurately measured except for each 24 hours, but 

 the estimated amounts per period recorded in table 162 are probably not far 

 from correct. 



An examination of table 162 shows wide variation in the daily intake of 

 water for the different experiments. The minimum amount consumed during 

 24 hours by any subject was 115.1 grams, and the maximum was 1467.1 grams. 

 In general these subjects drank less water than the 3 men who were the subjects 

 of experiments Nos. 59 and 68 to 77. Water from the city supply was used 

 and no allowance was made for the small amounts of organic matter and salts 

 which it contained.

Ukine. 



The urine was collected daily at 7 a. m., 1 p. m., 7 p. m., and 11 p. m. 

 Unfortunately the subject of experiment No. 79 did not collect the urine on 

 the first morning until an hour and a half after the experiment began. It 

 was impossible to make any satisfactory allowance for the excess included 

 in the preliminary urine and no attempt has been made to correct for it. 

 The error would probably be proportional to the time of the experiment and 

 hence from 6 to 10 per cent would represent the error. During experiment No. 

 85, a small quantity of the urine for the second period of December 9 was 

 spilled in the food aperture and on the floor of the chamber. This was 

 immediately taken up with cheese cloth, and the nitrogen content determined 

 and added to the total nitrogen for the day. The total weight of the urine
