Fig. 10. Observations on thermal gradient, with C. H. H. 



In the experiment represented by fig. 10, a double thermometer was used in 

 the rectum, one of the laboratory assistants (C. H. H.) serving as a subject. 

 It is interesting to note from the curves that between the depths of 0.5 centi- 

 meters and 6 centimeters, there is a difference in temperature amounting to 

 2.72 C. The curves rise very rapidly until the depth of 4 centimeters is 

 reached, continuing to rise much more slowly for the next 2 centimeters. 

 Apparently with this subject the temperature reached its highest point at a
