Volume of Urine. 



347 



in which the volumes of urine were 450 and 440 cc. respectively. At this 

 period of the fast, the subject was taking about 900 cc. of liquid per day. It is 

 moreover to be noted that since Jacques drank each day a part of his own urine, 

 and as the amounts so drunk are not specified, no correction can be made to 

 obtain the true intake of water. 



Among the observations on urine the records of the volumes of urine 

 voided by Succi are of unusual interest. 



In the fast reported by Luciani (4) the volume of urine excreted by Succi 

 remained quite constant. Only on the first day did the amount approximate 

 normal. On the day before the experiment began the volume was nearly 1500 

 cc, while on the first day of the fast it had fallen to 900 cc, and on the 

 second day to 500 cc. The lowest volume observed was 250 cc, on the 22d 

 clay of the fast. On the first 2 days he took no water, hence the urine excretion 

 is comparable on those days to experiments on fasting without water. During 

 the remainder of the fast Succi partook of water as desired.

In the Naples fast (21 days) reported by Ajello and Solaro (6), the volume 

 of urine voided by Succi varied from 960 cc. on the first day to 410 cc on the 

 tenth and fourteenth days. The drinking-water varied in amount from 2170 

 cc. on the thirteenth day to 620 cc on the twentieth day. After the first 9 

 days of the fast the subject took regularly about 30 grams of citrate of 

 magnesium. On 4 days from 200 to 300 cc of a saline water (Vichy 

 eleventh day, Janos 12, 20, 21) were taken.
