Investigations into the conditions governing the temperature of the body. 35 



the beginning felt appreciably; the left cheek was at a distance of 

 hardly 05 meter from the outer wall. The temperature in the room, 

 read from a thermometer near the head of the person experimented 

 on, fell from 21° to 18° С during the readings. The temperature 

 w^as measured at the same time on the right cheek and the left side 

 of the mouth. 



In the following measurements the right cheek was at a distance 

 of 04 meter from a lighted petroleum-oven with a cold draught of 

 air on the left side of the face.

In both these cases the skin thermometer was sheltered against 

 the radiating heat by the hand. But besides covering the thermo- 

 meter the hand sheltered part of the face against radiation and on 

 the left side the skin from the cold to some extent; this is probably 

 the reason why the temperature on the two sides, distinctly different 

 at the beginning, gradually becomes somewhat equalized. It appears 

 for the rest from the measurements, that the skin temperature reacts 

 much more strongly to the difference in the air temperature than 

 the mouth temperature does. The latter displays an unmistakable 

 though slight tendency towards varying in an opposite direction to 

 the skin temperature. 



On staying in the open air it is more difficult to prove the 

 direct dependence of the skin temperature on the air temperature, 

 as other meteorological factors, wind and moisture, also influence 

 the results.

In spite of the slight fall in the air temperature, there is a con- 

 siderable decrease in the temperature of the forehead, which must 

 undoubtedly be attributed to the wind.
