Influence of Inanition on Metabolism. 



Drinking-ivater. "Water was furnished as desired and consumed between 

 7 a. m. and 11 p. m. The quantities consumed per day and approximate 

 amounts per period are given in table 93. It will be seen that relatively large, 

 but often varied, amounts of water were consumed on all days of the experi- 

 ment. Thus during both the second and the third day the subject consumed 

 nearly 3 liters of water while on the last day the amount drunk was but a 

 little more than a liter. This marked variation in the amount of water con-

sumed on different days is but one indication of the noticeable differences in 

 bodily and mental states exhibited by this subject. In all of his experiments 

 there was frequent complaint concerning the water, although in this and 

 subsequent experiments, at the subject's request, distilled water was furnished. 



Urine. 



The urine was collected in 4 periods, as is customary. The weight, specific 

 gravity, reaction, nitrogen, creatinine, and, with the exception of the first day, 

 the phosphoric acid were determined for each period. The results are recorded 

 in table 94. The specific gravity in this and all subsequent experiments was 

 taken by means of the Westphal balance. The creatinine and phosphoric acid 

 were determined by Prof. L. B. Mendel, of Yale University. The usual check 

 on the accuracy of the analytical work was made by comparing the total 

 amounts of nitrogen, creatinine, and phosphoric acid as determined by periods 

 with those determined on the composite samples. In the case of nitrogen 

 and phosphoric acid the agreement was extremely satisfactory with the single 

 exception of the phosphoric acid for the fourth day of the experiment. 



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

 determinations given in table 94 in the samples from the different periods, 

 each day's composite sample was analyzed much more completely and the
