It appears clear that by some process of "acclimatization," "accustomization," or "cultivation," humans can better withstand exposure to cold than would otherwise be possible.* There can also be no doubt that the same process permits persons to work manually in extreme cold with greater dexterity and work efficiency than would otherwise be possible.2 As one observes such persons working under these circumstances, one, in addition, gains the impression that they can handle with their bare hands extremely cold objects without evidence of the local cold injury that might be expected to result in nonacclimatized subjects. Animal experiments, such as those of Blair et al.,3 and of Sellers and his colleagues4 have demonstrated that cold-acclimatized animals can be subjected to low environmental temperatures with better chance of survival and avoidance of cold injury than controls. The present study was undertaken to learn whether cold-acclimatization would have any effect
