Influence of Inanition on Metabolism. 



Changes in Body-Weight Compared with Balance of Income and Outgo. 



In table 171 the changes of body-weight obtained by weighing the subjects 

 each morning are compared with the losses of body material, i. e., the deter- 

 mined weights of the different factors of the outgo less those of the income. 



Although the comparisons in table 171 do not show exact balances, neverthe- 

 less, they are in general fairly satisfactory and for the most part there is a

 outgo Metabolism experiments Nos. 79-83, 86, and 89. 



1 The data in this column should not be confounded with urine data in other tables. See 

 explanation, p. 66. 



2 On Nov. 25, 118.0 grams of feces were excreted. This amount Is not Included in the total 

 outgo. See p. 120.

tendency for the errors in the individual days of each experiment to compensate 

 each other. A particularly poor balance was obtained on the first day of 

 experiment No. 79, the reason for which is not known. The average error in 

 terms of the calculated loss is for experiment No. 79, -{-55 grams or -f-4.9 per 

 cent of the average daily loss; for experiment No. 80, 17 grams or 0.9 

 per cent; for experiment No. 81, 7 grams or 0.6 per cent; for experiment 

 No. 82, 1 gram or 0.1 per cent; for exp. No. 83, 8 grams, or 1.1 per 

 cent; for exp. No. 85, 6 grams or 0.5 per cent; for exp. No. 89, 7 grams 

 or 0.6 per cent. The wide variation in exp. No. 79 is of course due to the 

 large error, 130 grams, on the first day. In all but two experiments the larger 

 loss of body-weight occurred on the second day.
