DISCUSSION OF RESULTS.

tions throughout the whole test were not sufficiently striking to make these 

 records of very great value in this connection. The records of the mouth 

 temperature are chiefly of interest as indicating the time required to warm the 

 cavity to approximate constancy. With the mouth closed about 10 minutes 

 prior to taking the temperature (see the curve at about 4 h 29 m p.m.), constancy 

 was reached in about 8 minutes. With the mouth open for 10 minutes pre- 

 vious to taking the temperature, a period of over 15 minutes was required 

 (see the curve at about 5 p.m.). 



The records of body-temperature may be found in fig. 29, the curves being 

 designated as usual.

Experiment of January 31, 1911, with Mrs. B I. In this experiment the 

 temperature was taken in the vagina with the deep and the shallow ther- 

 mometers; in the rectum with a single thermometer, also in the groin, and in 

 either the right or the left axilla, no hot-water bottle being used for preheat- 

 ing the artificial cavities. An attempt was also made to secure the temperature 

 of the mouth from time to time throughout the day, the subject being asked 

 not to breathe through the mouth previous to the observations. 



At the beginning of the experiment, the thermometer in the right axilla 

 was not in proper position, and it was accordingly readjusted at 9 h 58 m a. m. 

 When this temperature had attained the maximum, however, it remained 

 fairly constant. At ll h 58 m a.m. the subject changed from the couch to a 

 chair, and sat quietly reading, except between l h 04 m p.m. and l h 29 m p.m., 

 when she ate a dinner consisting of steak, coffee, and potato chips. At 3 h 25 m 

 p.m. she lay down again on the couch and remained either sleeping or lying 

 quietly awake for the rest of the experiment. During the time she sat in the 

 chair, the thermometer was placed in the left axilla, and that in the groin 

 removed. When she again lay down on the couch, however, the thermometers 

 were returned to their original positions. 



The curves for the deep and the shallow vaginal temperatures and for the 

 rectal temperature follow one another throughout the day with remarkable 

 regularity for the most part. The groin temperature required a long time to 

 reach the maximum, but thereafter the records followed those for the rectum
