The pronounced influence of the environmental temperature upon the curve 
for the skin temperature was especially studied by making temperature pho- 
tographs over exactly the same line at intervals from the moment of disrobing

FIG. 1 
Photographic records from a string galvanometer for skin temperatures at different parts 
of the nude body following a 27 hour exposure to an environmental temperature of 14.6°C. 
The thermal junction was moved at constant tempo from shoulder to ankle. Time reg- 
istered at bottom of each curve is in 2-second intervals. 
to the end of the period of prolonged exposure to cold. As would be expected, 
these show a progressive increase in the amplitude of the curve as the time of 
exposure is prolonged; marked changes occurring even inside of the first fif-
