Drinking-water. Drinking-water was furnished from the city supply and 

 the subject drank much larger amounts than any previous subject. The 

 quantities for each day, apportioned as nearly as possible among the different 

 experimental periods, are given in table 65. Great differences in the amount 

 of water consumed daily may be observed. While about 1200 grams were con- 

 sumed on the first day of the fast, on the second and third days the amount 

 consumed per day averaged more than 2 liters. On these 2 days a considerable

amount of water was taken between 7 and 11 p. m. On the first and last 

 days no water was consumed after 7 p. m. 



Urine. 



The urine was collected as usual at the end of each of the 4 periods, but 

 on the first day the subject accidentally mixed the urine of the first and 

 second periods. Determinations were made of the specific gravity, reaction, 

 and nitrogen of the urine for each period. These are recorded in table 66. 

 The quantity of urine voided is nearly proportional to the amount of water 

 drunk, there being on the third day over 2.5 liters passed. Throughout the 

 experiment the specific gravity was low and the reaction acid. 



Weight, composition, and heat of combustion of urine. Aside from the 

 determinations given in table 66 on the samples of urine for the 4 usual periods, 

 each daily composite sample was analyzed. Determinations were made of the 

 water, total solids, ash, nitrogen, carbon, organic hydrogen, phosphorus, sulphur, 

 and heat of combustion. From the percentages thus obtained, the heat of 

 bustion per gram and the weight of urine, the quantities of the various 

 elements and the total heat of combustion are computed. These are recorded
