THE most characteristic feature of the physiology of hibernation is the changing of a homoiothermic mammal within certain limits into a poikilothermic animal. Thus, for example, the body temperature of the hedgehog may decrease during hibernation to about 2° C. When the animal wakes from hibernation, its body temperature rises in some hours from 2°–5° C. to 30°–35° C. again, and the animal returns to homoiothermy.

The spinal cord and brain of hedgehogs and Eliomys quercinus store glycogen during the hibernation period in agreement with parallel in vitro assay on brain material and the distribution of histochemically detectable glycogen was mapped in all divisions of the central nervous system.

In the autumn of 1929 thirteen marmots were brought to Cambridge by one of us (Endres) after the hibernation period had commenced. Of these, we owe four to the kindness of Prof. Adolph Lowy of the
