STATISTICS OF EXPERIMENTS.

periods, each from 10 to 15 minutes in length, and ended at 5 h 05 m p. m. In the 

 first and second periods the subject thought there was a slight leak about the 

 noseclip, especially during one of three long breaths taken in the second period. 

 He was very quiet in these two periods, except for adjusting the noseclip in the 

 first minute of the first period. Between the second and third periods he sat 

 up between 3 h 09 m and 3 h 37 m p. m., and drank 200 c.c. of water at 3 h 10 m p. m. 

 He also drank 100 c.c. of water between the third and fourth periods, at4 h 47 m 

 p. m. In this intermission he slept most of the time. At the close of the fourth 

 period he had a slight headache. 



Before the second part of the experiment, the subject ate at 5 h 40 m p. m. 

 141.1 grams of oatmeal, 10.9 grams of butter, and 23.4 grams of cream. He 

 also drank 100 c.c. of water. At 6 p. m. he defecated, and at 6 h 10 m p. m. he 

 took 4 grams of sodium bicarbonate in 100 c.c. of water. At 6 h 15 m p. m. he 

 drank 200 c.c. of water. He lay down upon the couch again at 6 h 26 m p. m., 

 and four additional 15-minute periods followed, the first beginning at 6 h 44 m 

 p. m., and the fourth ending at 9 b 40 m p. m. Between the fifth and sixth 

 periods he sat up, but lay down again at 7 h 31 m p. m. In the intermission 

 between the sixth and seventh periods, he urinated at 8 h 03 m p. m., and also 

 drank 100 c.c. of water. During this period he expressed himself as being 

 quite tired, and lay down at 8 h 30 m p. m. In the seventh period he was very 

 quiet and awake, taking several long breaths near the end. He was reported 

 as tired in the last period, also, and very quiet and awake. After the experi- 

 ment was over he urinated and defecated at 9 h 50 m p. m. The records of the 

 experiment are given in tables 49 and 52.

1 Oatmeal, 297 gins., butter, 43.6 gms., and cream, 45.7 gms., were eaten between 2 h 10 m and 2 h 23 m p.m. 



2 Subject slept most of the time between this and the following period. 



3 Carbon dioxide eliminated per kilogram per minute, 4.23 c.c; oxygen absorbed per kilogram per minute, 6.03 c.c. 



4 Oatmeal, 141.1 gms., butter, 10.9 gms., and cream, 23.4 gms., were eaten between 5 h 40'" and 6 h 15 m p.m.

Calorimeter Experiment No. P8. 



Date, October 9-10, 1911 . Body-weight without clothing, 40 kilos. 



In this experiment, which was the fourth of Series II, the subject spent the 

 night in the bed calorimeter. When the subject entered the apparatus at 

 10 h 15 m p. m., he was dressed in pajamas and socks, and two pillows and two 

 blankets were given him. The stethoscope and the pneumograph about the 

 chest were not used, but only the pneumograph about the thighs to obtain, a 

 record of the muscular movements. The measurements of the metabolism 

 began at ll h 49 m p. m., October 9, and continued for six periods of varying 

 length, ending at 7 h 41 m a. m., October 10. The subject was reported as having 

 moved in the fourth period; in the fifth period he moved about, telephoned,
