Respiration Experiment No. Kl. 



Date July 27, 1910. Body-weight without clothing, 55.6 kilos. 



The subject came to the laboratory fasting, having had no food since the 

 evening meal of the day before. The experiment included but one period of 

 approximately 15 minutes, beginning at 7 h 24 ra a. m. This period was without 

 incident, the subject remaining very quiet. The results of the experiment 

 may be found in table 14. 



Respiration Experiment No. K2. 



Date, July 29, 1910. Body-weight without clothing, 55.6 kilos. 



On the morning of the experiment, the subject came to the laboratory 

 without breakfast and lay down upon the couch at 8 h 20 m a. m., and the experi- 

 ment began at 8 h 34 m a. m., continuing for three periods of 11 to 14 minutes, 

 with intermissions of 8 to 10 minutes. During the first period the subject 

 cleared his throat once, and there was probably a slight loss of air. In the 

 second period he moved his hands several times and his leg once. In the third 

 period he lay quietly the whole time. The results of the experiment are given 

 in table 14. 



Respiration Experiment No. K3. 



Date, August 2, 1910. Body-weight without clothing, 55.6 kilos. 



The subject came to the laboratory without breakfast at 7 h 30 m a. m. and 

 lay down on the couch at 7 h 35 ra a. m. The experiment began at 7 h 50 m a. m., 

 and continued for three periods of 13 to 15 minutes each, with intermissions of 

 8 to 13 minutes, ending at 8 h 54 m a. m. After the close of the second period the 

 pneumograph was loosened, as the subject complained it was too tight. Before 

 the beginning of the third period the subject raised both legs up at the knee, 

 and near the end of this period he straightened out one leg. The results of the 

 experiment are given in table 14.
