Studies on the Electrical Potentials of Living Organisms: II. Effects of Low Temperatures on Normal Unanesthetized Mice *

In a preceding paper (Marshall and Meader') we reported a study of base-line bio-electric potentials in normal unanesthetized mice, preliminary to the investigation of the effects of altered external and internal environmental factors. In the present communication are presented the records of electrical potentials obtained during the depression of body temperature and its return to higher levels, together with observations on some physiological concomitants of the process.
