DISCUSSION OF RESULTS. 



67 



The general tendency toward parallelism of all of these curves is rather 

 striking; nevertheless, the temperature of the mouth 'exhibits considerable 

 fluctuation from time to time, 

 and the temperature of the left 

 axilla falls off more rapidly be- 

 tween ll h 18 m a. m. and ll h 48 m 

 a. m. than do cither the deep or 

 the shallow rectal temperatures, 

 these differences being more 

 marked than in most of the ex- 

 periments. The rapidity with 

 which the temperature of the 

 left axilla came to constancy after 

 the use of the hot-water bottle at 

 12 h 47 m p. m. is also noticeable. 



The measurements of the body- 

 temperature are shown in fig. 33. 



Experiment of March 1, 1911, 

 with C. H. H. The deep and 

 shallow rectal thermometers were 

 used in this experiment, with an 

 insertion of 12 and 8.5 centimeters, 

 respectively. A thermometer was 

 also used in the left axilla, and 

 one in the mouth. This experi- 

 ment was designed to duplicate 

 more Or less the experimental con- 

 ditions of the study made with 

 J. J. C. on February 27. The 

 mouth temperature was not taken 

 continuously, however. A hot- 

 water bottle at a temperature of 

 43 C. was used in the left axilla. 

 The subject was eating between 

 12 h 37 m p. m. and l h 04 m p. m.; 

 at l h 05 m p. m. he changed the 

 position of his feet, resting them 

 on a stool instead of on the couch. 



The parallelism of the curves is 

 very striking in all instances, the 

 curve for the axilla, although 

 showing a lower temperature, fol- 

 lowing the curves for the rectal c o 

 temperature very satisfactorily. 



The measurements of the body-temperature may be found in fig. 34.
