 Fig. 12.- — The open circles represent the average oxygen consumption of three hamsters wak- 

 ing from hibernation at an environmental temperature of 4° to 5° C. The closed circles rep-

 perature of the same animals. Note that the rectal temperature rises more slowly than that of the 

 cheek pouch.
