Investigations into tlie conditions governing the temperature of tlie body. 15 



like the following probably gives the approximate relation between 

 the changes in the local temperatures dealt with here. 



Temperature in Rectum Mouth Forehead 



^Vs 06. 11,55 a. m. before meal 3686° С 3625° С. 32-50° С. 

 — 12,40 p. m. after meal 3709° - 3668° - 3335° - 



Work and temperature. 



The temperature changes occasioned by the meals are, however,^ 

 but small compared with those due to the w^ork of the muscles. 

 This is the factor which more than any other determines the varia- 

 tions of the rectal temperature. The more sedentary one's mode of 

 life is, the straighter is the course of the temperature curve, and 

 on the other hand every bodily exertion will appear the more 

 distinctly in the curve and change its regular shape; the more the 

 bodily work, the higher the whole curve will be — other conditions 

 being the same. 



It lies in the nature of the case that no average value can be 

 given for the rise of temperature occasioned by the work of the 

 muscles; nor can the maximum and minimum values be found, the 

 lowest limit especially being undeterminable. The uppermost limit 

 will be individually very variable according to the muscular devel- 

 opment and training of the person corcerned. Some examples show 

 best the extent of these variations
