Drinking-water. Table 122 records the daily consumption of water, and the 

 amounts taken in different 2-hour periods. In this experiment the subject 

 measured and recorded the amount of water drunk. The table shows that on 

 different days, there is no uniformity in the amounts of water drunk in any 

 given period. The amounts consumed were less than in the previous fasting 

 experiment. The average for the 7 days was not far from 1800 grams per day. 



1 Period during which water was consumed, was assumed in some instances. (See page 73.) 



Urine. 



The usual method of collecting the urine in four periods was followed. In 

 the samples obtained each period, the weight, specific gravity, reaction, 

 nitrogen, phosphoric acid by titration, and creatinine were determined. The 

 results of these determinations are recorded in table 123. The specific gravity 

 was invariably low and the reaction acid. The agreement between the deter- 

 minations of nitrogen, phosphoric acid, and creatinine, in the different periods, 

 with the total determined on the daily composite was in all cases very satis- 

 factory. The results recorded in, column g of the table indicate the amount 

 of preformed creatinine excreted in the urine and do not include the preformed 

 creatine which was subsequently determined and is recorded in table 124, 

 page 178. 



Weight, composition, and heat of combustion of urine. In addition to the 

 determinations made on the samples of urine collected each period, a much 

 larger number of determinations were made on the composite urine for each 

 day. From the percentages thus obtained and the weight of urine, the 

 quantities of elements and compounds excreted have been computed and
