Experiments with Women. 89 



rest period began at 9 h 10 m a. in. and continued until 12 h 10 m p.m., the sub- 

 ject being busy most of the time with the usual copying. At 9 h 14 m a. m. 

 he went to the food aperture. During the period from 12 b 10 m p. m. to l h 10 m 

 p. m., a part of the time was occupied in the undressing and weighing processes, 

 which were finished at 12 h 35 m p. m. From 12 h 35 m p. m. until l h 10 m p. m. 

 the subject remained quiet. He was undressed 5 m 19 s . 



The pulse-rate as obtained by the subject was as follows: S h 50 m a. m., 93 : 

 9 h 15 m a. m., 88 ; 9 h 45 m a. m., 93 ; 10 h 15 m a. m., 81 ; 10 h 45 m a. m., 79 ; 1 l h 15 m 

 a.m., 79; ll h 45 m a.m., 80; 12 noon, 79; 12 h 30 m p.m., 71. The sublingual 

 body-temperature was as follows : 9 h 10 m a. m., 97.4 F. ; 12 h 10 m p. m., 97. G F. ; 

 l h 10 p. m., 97.8 F. The results of the metabolism as obtained in these 

 periods are given in table 44. 



Experiments With Women. 



Five experiments were made with two young women who were students in 

 Wesleyan University, and had volunteered to act as subjects. These experi- 

 ments were conducted on the same plan as that used in the other normal 

 experiments with students and assistants in the laboratory. 



METABOLISM EXPERIMENT No. 179. 



Subject. C. F. S., June 16, 1905. Age, 21 years 7 months; 

 height, 161 cm.; weight without clothing, 62.2 kilos. 



The subject entered the respiration chamber at the usual time for these 

 experiments, that is, about S a. m. She had eaten previously a breakfast 

 consisting of bananas, half slice of toast, 3 radishes, and half cup of milk. 

 The experiment began at 9 h 32 m a. m. and the subject immediately went to 

 the food aperture and placed the clinical thermometer in it. As she was not 

 familiar with the operation of opening the food aperture, there was considerable 

 muscular effort in doing this, and she was at the food aperture several minutes 

 before finally opening it. She went to the food aperture again at 9 h 46 m a. m.. 

 opened it, and immediately after sat down. During the first half hour she 

 ate 85 grams of bananas. This experiment consisted of only one 2 h 30 m period, 

 ending at 12 h 02 m p. m. Host of this time the subject was sitting in the 

 chair reading. 



This was the first experience of this subject in the respiration chamber and 

 she was entirely unfamiliar with the apparatus or with any of the operations 

 connected with it, so that there was considerable novelty for her in the ex- 

 perience. However, she made no comments regarding her stay, except to say 

 that the temperature seemed high at first and that it gradually lowered during 

 the experiment.
