DISCUSSION OF RESULTS.

constancy and the thermometer was later removed, and two thermometers 

 were placed side by side in the left groin. 



The usual initial fall in temperature on lying down on the couch is well 

 shown in the curves for the deep and shallow rectal thermometers and for the 

 vaginal thermometer. The temperatures for these three localities followed 

 one another with fair constancy throughout the whole test. The groin tem- 

 perature required considerable time to reach constancy, but thereafter followed 

 the fluctuations in the temperature of the rectum and the vagina with reason- 

 able regularity. As will be seen by the curves, the thermometers used in the 

 latter part of the experiment for obtaining the temperature of the groin agreed 

 fairly well with each other, and also followed closely those of the rectum and the 

 vagina. While the temperature indicated by the shallow rectal curve is 

 considerably lower than that of the deep rectal curve, it is interesting to note 

 that the parallelism of the two records is very marked. 



The records for this experiment are given in fig. 24 ; the curves are designated 

 in the usual manner, the curve for the thermometer between the arm and the 

 breast being marked S, and those for the groin, Gi and G 2 . 



Experiment of January 17, 1911, with Mrs. B I. In view of the parallelism 

 shown in the previous experiment between the groin temperature and the 

 temperatures of the rectum and the vagina, this experiment was designed to

make a comparative study of the temperatures of the groin, the deep and the 

 shallow vagina, and the rectum, a thermometer being placed in all of these 

 localities. In the rectum, the thermometer was inserted to a depth of 7 

 centimeters, while in the vagina, one thermometer was inserted to the depth 

 of 10 centimeters, and the other to the depth of 6.5 centimeters. Before 

 the experiment began, a hot-water bottle at a temperature of 42 to 43 C. 

 was placed in the groin for 5 minutes. From the curves, it may be seen that 

 the groin temperature was at first considerably higher than normal, then 

 fell off until it reached a constant level somewhat below that of the vagina and 

 the rectum, and thereafter followed in a general way the fluctuations of the 

 other thermometers. 



The records of the experiment may be found in fig. 25, with the curves 

 designated as usual.
