348 Influence of Inanition on Metabolism. 



In the Vienna fast (21 clays) reported by E. and 0. Freund (10) the volumes 

 of urine varied from 1435 cc. on the first day to 235 cc. on the 21st day. The 

 records of the amount of drinking-water are not given. The volumes of 

 urine from the 23d to the 30th day of Succi's fast at Hamburg, reported by 

 Brugsch (12), are twice as large as those of the last 10 days of the Vienna fast. 

 In the Hamburg fast, Succi voided 1030 cc. of urine on the 30th day, and the 

 smallest volume recorded was 520 cc. on the 29th day. The subject drank 

 about 750 cc. of water each day of the fast. This amount of liquid was 

 increased on the 30th day by 300 cc. of a sweetened lemonade. 



A tabular statement showing the daily volumes of urine voided by the 

 subjects of the fasts discussed above, as well as those of a professional fasting 

 woman (11), is given herewith in table 192. 



Vozarik 39 in studying the influence of the character of the diet on the 

 quantity of urine excreted, observed volumes excreted on single fasting days 

 amounting to 905, 1405, 2240 cc, respectively. Since, as the author clearly 

 points out, the character of the diet before the fasting period influenced in 

 large measure the volume of urine excreted, and since unfortunately the 

 nitrogen excretion was not determined, the results are of but little value in 

 this discussion. 



Not only have the exact data of the amounts of urine, and the water 

 consumed, been recorded in the Middletown experiments, but the amounts of 

 water in urine and the daily ratios of the water of urine to ingested water have 

 also been obtained. The results are presented in table 193, page 355. 



For convenience of discussion, and since the data above show that the 

 volume is proportional to the drinking-water to a certain extent, the con- 

 sumption of drinking-water is considered before proceeding to the particular 

 point under discussion, i. e., the volume of urine. 



RELATION OF DRINKING-WATER TO VOLUME. 



The amount of drinking-water consumed by the subjects in different experi- 

 ments varies greatly. In the experiments reported herewith the maximum 

 consumption is 2763.2 grams on the third day of experiment No. 73, and 

 the minimum 115.10 grams on the first day of experiment No. 89. Even in 

 experiments with the same subject the variations are considerable. For 

 example, in experiment No. 73 with S. A. B., the average amount of drinking 

 water per day was 2124.74 grams, while in experiment No. 77, with the same 

 subject, the average was 1405.45 grams. The maximum amount was consumed 

 by this subject on the third day of experiment No. 73, 2763.20 grams, and 

 the smallest amount on the last day of experiment No. 77, 962.00 grams. 

 Experiments Nos. 68 and 69, both of which were made with another subject 

 (A. L. L.), also show marked differences in the amount of water consumed.
