Influence of Inanition on MeTxIbolism. 



Only one of the fasting experiments continued for more than 5 days. In this 

 instance the loss of body-weight was 0.391 kg. on the sixth and 0.497 kg. 

 on the seventh day. 



While, therefore, marked fluctuations in the loss of body-weight on the 

 first, second, and third days of fasting are to be noted in practically every 

 experiment, the loss on the fourth and succeeding days seems to be much more 

 nearly uniform and judging from experiments Nos. 73 and 75, the average 

 loss per day is not far from 0.57 kg.

1 Computed by dividing the loss of weight for any given 24 hours "by the average of the 

 body-weights at the beginning and end of the same 24 hours. The average is the sum of the 

 percentages thus obtained divided by the number of days considered. 



2 Beginning weight assumed. See p. 47. 5 Weights include all clothing. 



8 Weights include underclothing. 6 Weights without clothes. See Table 186. 



4 Weights without clothes. 



The irregularities in variations in body-weight in these experiments are very 

 considerable but they are by no means so large as those observed in experiments 

 with Succi and Jacques. (See table 185.) On some of the days in the long 

 fasts with these men actual gains in body-weight have been recorded. 



The most noticeable instance of a gain in weight is in that imperfectly 

 reported experiment of Tanner in which it is stated that after having fasted 

 for 16 days without water an actual gain of 4^ pounds followed the ingestion 

 of water. In none of the fasting experiments reported here (table 186) was
