Calorimeter Experiment No. N9. 



Date, December 14, 1910. Body-weight without clothing, 31.4 kilos. 



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

 and entered the bed calorimeter at 7 h 32 m a. m. The experiment began at 

 8 h 21 m a. m., continuing for two 45-minute periods and one 40-minute period,

ending at 10 h 31 m a. m. As usual with this subject, he lay quietly reading dur- 

 ing practically the whole experiment, save at the beginning of the third period, 

 when he moved quite a little. Samples of alveolar air were taken and records

record of 90 mm. for the blood-pressure was obtained at 7 h 10 m a. m. The sub- 

 ject urinated at 7 a. m., before coming to the laboratory, and at 10 h 55 m a.m., 

 after the experiment was over. No water was taken. The results of the 

 experiment are given in table 32.

'Carbon dioxide eliminated per kilogram per minute, 3.92 c.c: oxygen absorbed per kilogram per minute, 5.54 

 c.c. The urine collected between 7 a.m. and 10 h 55 m a.m. amounted to 390 c.c, specific gravity 1.025, and contained 

 1.49 gms. of nitrogen and 10.6 gms. of sugar.
