Temperature regulation and cold acclimation.

The questions concerned with temperature regulation raise sufficient controversy in themselves so that little but valor or foolishness can be attributed to one who chooses to discuss this subject in the furor of a second controversy acclimatization. However, I should like to introduce the papers of this session with a summary and a synthesis of the data with respect to control of metabolism and peripheral circulation on cold exposure. The term “acclimatization” as I use it might well be synonymous with acclimation, adaptation, or habituation. What is of concern is cold exposure.
