It ought perhaps to be remarked that the rise of the mouth 

 temperature is in botli these cases lower than the average rise, 

 which as stated below is about 05°, 



The result of 32 measurements taken twice displays a mean 

 deviation of 052° i 006, /и = 034 = 65 ^/o of mean. Thus, very 

 great variations occur, and consideration of the separate observations 

 readily shows the origin of the great diversity. All the very great 

 differences occur on going into a meal in a heated room after being 

 in the open air or in a cold room ; conversely, the differences are 

 small when the meal is taken in a cold room after coming from a 

 heated room. In my cases, all of which refer to meals within doors, 

 I have never found a fall of temperature after the meal; the greatest 

 deviation measured was 15°, the least 0. The 32 deviations are for 

 the rest distributed among 13 plus and 18 minus differences, the 

 difference in one case being 0; of these 



This "advantageous" distribution is due to the few large variants 

 which give a disproportionately high value for /i. 



Omitting the 5 largest deviations the average is almost un- 

 changed (047°); but /J. decreases almost to the half. In a small 

 group of 7 cases, where the temperature was measured together with 

 other physiological functions before and after meal in the middle 

 of the da}^ and where I stayed in a comparatively warm room 

 during both series of measurements, the rise of the temperature was
