times and turned over, and rose at 7 o'clock on the morning of April 17. Five 

 6-hour periods were measured in this experiment, beginning at 1 a. m.. April 

 17, and ending at 7 a. m., April 18. During two of these periods, the first and 

 last, the body conditions were identical so as to afford reasonable basis for 

 comparison. 



Program and records of activity and body-temperature. Aside from being 

 instructed to move about as little as possible and not to make movements with- 

 out notifying the observer, no prescribed program was laid down for this 

 subject. He ate 3 meals during the course of the day, retired at the usual 

 time (10 o'clock at night), and slept until 7 o'clock in the morning. In this 

 experiment it was not practicable to separate the urine in the number of 

 periods; therefore we have only the total urine for the 24 hours. No attempts 

 were made to separate the feces, although there was a defecation inside the 

 chamber during the experiment. A record of muscular activity as made by 

 the observers is appended hereto.
