Calorimeter Experiment No. N7. 



Date, December 10, 1910. Body-weight without clothing, 31.8 kilos. 



The subject arrived at the laboratory at 7 h 10 ra a. m., without breakfast. 

 Before he entered the bed calorimeter at 7 h 33 m a. m., samples of alveolar air 

 were taken and a record made of the ventilation of the lungs. The experiment 

 began at 8 h 22 m a. m., ending at 10 h 40 m a. m., after three 45-minute periods. 

 At 9 h 56 m a. m. the subject drank 76 c.c. of water. During the first period he

was very quiet, reading. He did not read during the second period, but lay 

 very quietly, and slept about 20 minutes. In the third period, however, he 

 moved considerably and gave evidence of being very restless. Samples of the 

 alveolar air were also taken after the experiment. The subject urinated before 

 the experiment at 6 h 45 In a. m. and after the experiment at ll h 05 m a. m. The 

 data regarding the metabolism measurements and the average pulse and respi- 

 ation rates are given in table 28 and the statistics of urine in table 29.

Calorimeter Experiment No. N8. 



Date, December 12, 1910. Body-weight without clothing, 31.7 kilos. 



The subject reached the laboratory at 7 a. m., without breakfast, and 

 entered the bed calorimeter at 7 h 38 m a. m., after two samples of the alveolar air 

 had been taken and records made of the ventilation of the lungs. A blood- 

 pressure of 90 mm. was also recorded at 7 h 30 m a. m. The experiment began at 

 9 a. m., continuing for two 30-minute and one 40-minute periods, ending at 

 10 h 40 m a. m. The pulse and respiration rates were obtained as usual by the 

 stethoscope and pneumograph. The telephone was used once during the 

 experiment, at the beginning of the first period, but otherwise the subject was 

 very quiet, reading nearly all of the time except near the end of each period. 

 Samples of the alveolar air were taken at the end of the experiment, as usual. 

 Before coming to the laboratory, the subject urinated at 6 h 45 m a.m., and again 

 at ll h 08 m a. m., after the experiment was over. No water was taken during 

 the experiment. The data regarding the metabolism measurements and the 

 average pulse and respiration rates are given in table 30 and the statistics of 

 urine in table 31.
