Influence of external temperature on the body temperature of a rabbit fixed on its back was examined. The decrease of atmospheric temperature to 0°C failed to effect any marked decrease of body temperature in unfixed rabbits. The rabbits were fixed on its back at this temperature, and when the body temperature has decreased considerably, pyrogen and a substance which normally effects lowering of body temperature in rabbits were administered. As a result, it was found that the body temperature failed to rise by the administration of pyrogen in minimum pyrogenous amount, but the lowering of body temperature was also found to be small.
