that, on the other hand, the consumption of fat, and as a 

 result the excretion of carhonic acid and taking up of oxy- 

 gen, is greatly increased, as is also the amount of water 

 evaporated through lungs and skin. In hunger the differ- 

 ence between the carhonic acid in rest and in work is more 

 considerable (471 grammes) than on an average diet (281 

 grammes) ; the oxygen shows a similar result, 310 grammes 

 against 148 grammes, while the differences in the water 

 evaporated are relatively less, viz., 956 and 796 grannnes. 

 One might perhaps be inclined to believe that while the 

 total amount of albuminoids consumed in the twenty-four 

 hours was the same, the amount was larger during the 

 period of work, and correspondingly less during the hours 

 of i*est. In order to test this, the experiments were each 

 divided into two parts, the time from 6 a.m. to 6 p.m., in 

 the course of which the work was performed, beins: desi^- 

 nated as day, and the time from 6 p.m. to 6 a.m. as night. 

 The following results were obtained for the nitrogen, cai*- 

 bonic acid, and water excreted :
