Calorimeter Experiment No. Ql. 



Date, November 19, 1910; body-weight without clothing, 51.4 kilos. 



The subject came to the laboratory early in the morning without break- 

 fast and entered the bed calorimeter at 7 h 10 m a. m. The experiment began at 

 8 h 09 m a. m., and continued for three 45-minute periods, ending at 10 h 24 m a. m. 

 The pulse and respiration rates were obtained in the usual way. Throughout 

 the whole experiment the subject lay on his back, reading, and was very quiet. 

 After the experiment was over he said that although he felt rather warm he was 

 very comfortable and found his stay in the chamber pleasant. The records 

 of the experiment may be found in table 59.

1 Carbon dioxide eliminated per kilogram per minute, 3.42 c.c.; oxygen absorbed per kilogram per minute, 4.51 c.c. 

 The urine collected between 6 h 4 5 m and 10 h 4'J m a.m. amounted to 270 c.c; specific gravity 1.029, and contained 

 1.75 gms. nitrogen and S gms. sugar. 



Calorimeter Experiment No. Q2. 



Date, November 21, 1910. Body-weight without clothing, 51.5 kilos. 



Previous to coming to the laboratory at 7 a. m. the subject ate a break- 

 fast consisting of approximately 60 gms. oatmeal (weight uncooked) and 90

90 gms. cream. 

 2 Carbon dioxide eliminated per kilogram per minute, 3.73 c.c ; oxygen absorbed per kilogram per minute, 4.70 c.c. 



a pneumatic mattress, with his head resting upon two pillows and lifted to an 

 angle of 35 by means of a wooden head-rest. Throughout the experiment he 

 lay very quiet on his back, without reading. Just before entering the calorim- 

 eter the subject drank water, but no water was taken during the experiment. 

 He urinated at 6 h 50 m a. m., before coming to the laboratory, and again at
