same time, so that the only variable factor was the air temperature. On the last two 
occasions breakfast was taken in the laboratory after the walk instead of before. 
The readings are given in degrees centigrade.

With regard, then, to the effect of muscular work on the mouth temperature, my 
results do not agree with those of LINDHARD. 
On every day except one, the effect 
of a not very long walk was to raise the mouth temperature as well as the rectal, and 
On all but two of these days the walk was begun 
very shortly after finishing a hot breakfast, when the mouth temperature was artificially 
usually the rise was very distinct. 
* A thermometer was carried in the hand during the walk, and the lowest air temperature reached was noted ; 
this is indicated by the first figure, and the second gives the temperature of the room in the laboratory, where the 
observations were made zmmedzately on entering it. 
+ On this occasion I walked to the laboratory in company with a friend, with whom I was conversing all the way. 
On all the other days I breathed through the nose and kept the mouth closed.
