a This period includes the 3 days of the experiment proper and 3 days of a preliminary experiment 
not reported. here. 
The urine in these experiments, as in those preceding, was collected 
at intervals throughout the day. Instead of dividing the 24 hours 
into four equal periods, however, the da} T was subdivided into two 
periods of 6 hours, one of 4 and one of 8 hours. The object of this 
was to avoid waking the subject at 1 o'clock at night, since he experi- 
enced some difficulty in dropping to sleep readily afterwards. Tables 
71 and 72 give the data for the amount and composition of the urine 
during these experiments. The urine was not collected after the close 
of the experiments. The urine had begun to decompose before the 
heats of combustion of the daily samples could be determined, con- 
sequently the daily elimination of energy has been computed accord- 
ing to the manner followed under similar circumstances in experi- 
ments Nos. 13 and 14.
