upon the couch. The experiment began at 11 a. m., continued for three 

 periods of 12 to 13 minutes each, with intermissions of 12 to 16 minutes. 

 Throughout the whole experiment the subject was very calm and quiet. The 

 results of the experiment are given in table 80.

1 Subject ate breakfast at 6 h 45 ln a.m. 



2 Carbon dioxide eliminated per kilogram per minute, 3.48 c.c.; oxygen absorbed per kilogram per 



minute, 4.95 c.c. 



Calorimeter Experiment No. U5. 



Date, March 31, 1911. Body-weight without clothing, 39.9 kilos. 



This was the initial experiment of Series I, and the first with this subject in 

 the bed calorimeter. She arrived at the laboratory at 7 h 40 m a. m., without 

 breakfast, and entered the apparatus at 7 h 55 m a. m. The experiment began 

 at 8 h 50 m a. m., continuing for two 45-minute periods, ending at 10 h 20 m a. m. 

 The subject lay very quietly reading during all of the experiment, except near 

 the end of the periods. Both pneumographs and the stethoscope were used to 

 obtain the respiration-rate, the muscular activity, and the pulse-rate. The 

 results of the experiment are given in tables 81 and 83.

Respiration Experiment No. U6. 



Date, March 31, 1911. Body-weight without clothing, 39.9 kilos. 



This experiment, which was the second and last of Series I, was divided 

 into two parts, the subject continuing to fast after leaving the bed calorimeter 

 until after the first two periods had been concluded. She then took 100 grams 

 levulose, 100 c.c. weak coffee, and 175 c.c. hot water. Six additional periods 

 followed. 



The experiment began at 10 !l 50 m a. m., the two fasting periods ending at 

 ll h 38 m a.m. The food was taken at 12 o'clock, and the following six periods 

 began at 12 h 16 m p. m., ending at 3 h 08 m p.m. Each period was about 15 min- 

 utes long, the intermissions ranging from 8 to 31 minutes. The subject was 

 awake during the first period, and coughed once at 10 h 51 m a. m., also several 

 times in the second period. There were slight movements reported in the fourth, 

 seventh, and eighth periods. The subject urinated after the experiment at 

 3 h 15 m p. m. The results of the experiment may be found in tables 82 and 83.
