Mast curve. —The behavior of the mast cells was very similar to 
that of the eosinophiles, and the curve was irregularly parallel with 
the eosinophile curve. 
Figure 2 shows in detail the various curves for one animal following 
exposure to the sun.

BODY TEMPERATURE 
The body temperature of animals is known to show more variations 
than the body temperature of man. In animals many external conditions 
causb variations in body temperatures. Lee (1) has called attention to 
recent findings of the New York Commission on Ventilation with respect
