Abstract
The noradrenaline and adrenaline contents of the adrenal gland in cats were estimated by the permanganate method of Suzuki and Ozaki. Hypothermia was induced by immersing the animals into cold water.
After application of cold to the animal body a marked decrease in adrenaline content of the adrenal gland was found, whereas there was no definite alteration in adrenal noradrenaline content.
