The data are given in table 72. 



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



As in preceding experiments, actual weighings were used to check the 

 computed losses of body material. From the records of the weights of drinking-

 c of table 73. The outgo requires special consideration. Contrary to the ex- 

 perience of the subjects of experiments Nos. 59, 68, and 69, the subject of this 

 experiment defecated on each of the first 3 days. The large amount of vege- 

 table material in his diet affected peculiarly the passage of feces, 27 as is espe-
