Investigations into the conditions governing tlie temperature of the bod\^ 23 



On measuring the temperature in the rectum after sedentary 

 work alternately in a upright (st) and a lying (r) position, we find 

 results which vary but little from one another and without any 

 fixed tendency.

3701° - 37-01° - 



The temperature was first measured in the st and then in the 

 r position at intervals between the individual measurements suffi- 

 ciently long for the necessary cleaning and reading of the thermo- 

 meter and the noting of the results. 



If, however, we measure the temperature after standing still or 

 moving slowly about, the result differs somewhat. 



Much the same is the case when the temperature has been 

 raised owing to work.

It is common to these 3 series that the second reading in the 

 st position only varies a little and in a variable direction from the 

 first measurement in the r position; in other words, there is a 

 tendency towards lower temperatures in the r than in the s posi- 

 tion; but this soon vanishes on the measurements being continued. 

 We then find distinct falls in both positions, and then the temper- 

 ature becomes the same for the st and r positions, as in the example 

 first given.
