when he moved considerably. After the experiment was over he seemed to be 

 very tired and glad that it was over. Before coming to the laboratory the sub- 

 ject urinated at 7 h 30 m a. m., and again, after the experiment, at ll h 03 rn a. m. 

 The records of the experiment are given in table 74.

1 Subject drank a cup of coffee at 6 h 30 m a.m. 



: Carbon dioxide eliminated per kilogram per minute, 3.32 c.c.; oxygen absorbed per kilogram per minute, 4.66 c.c. 



The urine collected between 7 h 30 m a.m. and ll h 03 m a.m. amounted to 345 c.c, specific gravity 1.030, and 



contained 1.52 gms. nitrogen and 12.4 gms. sugar. 



Calorimeter Experiment No. T2. 



Date, February 16, 1911. Body-weight without clothing, 51.3 kilos. 



This was also a fasting experiment, neither food nor coffee being taken 

 after the evening meal of the day before. The subject came to the laboratory 

 at 7 h 30 m a. m., and the experiment began at 8 h 47 m a. m. After two 45- 

 minute periods the experiment ended at 10 h 17 m a. m. Throughout the whole 

 experiment the subject lay quietly on his back. He appeared to be somewhat 

 tired at the end of the experimental period, but had evidently become more

accustomed to the apparatus and the routine. The pulse and respiration 

 rates were obtained in the usual way with the stethoscope and pneumograph, a 

 second pneumograph being used about the thighs to give a record of any major 

 movements. The subject urinated at 7 h 42 m a. m., but was unable to urinate 

 again after the experiment was over. The records of the experiment are given 

 in table 75.
