During the rest experiments, in which the subjects had as 
little muscular activity as possible, there was but little differ- 
ence in the elimination of carbon dioxid during the two day 
In the seven experiments with E. O. 
and first night periods. 
the average rate per hour during these three periods was 38.3, 
37.8, and 36.1 grams, respectively.
