In relatively recent years experiments have indicated that the metabolic rates of cold blooded animals are not uniquely a function of environmental temperature as had been supposed. Acclimatization studies have revealed the existence of compensating mechanisms in poiliklotherms which enable them to establish metabolic levels that are partially independent or temperature. The means, however, by which these altered metabolisms are established and the responsible sites have not been fully determined. In view of this, an investigation was begun that might aid in realizing the nature of these mechanisms. It was hoped that this would be accomplished by answering two questions. First, does temperature acclimatization alter the metabolic rate of Rana pipiens, and second, are the effects of acclimatization reflected at the tissue level?
