rate being counted at the wrist. The experiment began at 8 h 23 m a. m., con- 

 tinuing for three periods of 11 to 13 minutes, with intermissions of 10 to 17 

 minutes, ending at 9 h 26 m a. m. The subject remained quiet throughout all 

 three periods, except for raising her hand to her head once in the first period. 

 The surgeon's plaster was not used to close the mouth, nor did it appear to be 

 necessary. The subject urinated at 7 a. m., and again after the experiment at 

 9 h 30 m a. m. The results are given in tables 35 and 39.

This experiment was carried out in the afternoon of the day on which 

 experiment No. 01 was made, after food had been taken. The diet for this day 

 was that of a regular vegetable day, with the addition of 4 eggs and one-half 

 pint of cream. The subject arrived at the laboratory at about 3 p. m., and 

 immediately lay down upon the couch. The experiment began at 3 h 12 m p.m., 

 continued for three periods 11 to 12 minutes in length, with the usual inter- 

 missions, and ended at 4 h 16 m p. m. During the second period, some difficulty 

 was experienced in obtaining a record of the pulse-rate. The subject was 

 extremely quiet throughout the whole experiment. The records are given in 

 tables 36 and 39.

Respiration Experiment No. 03. 



Date, September 23, 1910. Body-weight without clothing, 52.3 kilos. 



The experiment was made on an oatmeal day, the first being a fasting 

 period, and the second period following an oatmeal breakfast. The subject 

 then returned to the hospital, but after a dinner containing oatmeal, came 

 back to the laboratory and two additional periods followed. The experiment 

 was concluded by two periods after the subject had been again to the hospital 

 and eaten a lunch containing oatmeal. 



In the morning she reached the laboratory at 7 h 55 m a. m., without break- 

 fast, and lay on the couch about 10 minutes before the experiment began at
