1. The rises in oxygen consumption of rats and in the radio‐iodine uptake by their thyroid glands which occur when the environmental temperature is lowered are in no way diminished after the adrenal medulla is extirpated. 2. Extirpation of the adrenal medulla is not followed by a fall in body temperature either under an environmental temperature of 29·5o° C. or after exposure to an environmental temperature of 18o° C. 3. The rise in radio‐iodine uptake on exposure to cold appears to be due to some mechanism independent of the balance between thyroxine and thyrotrophic hormone concentrations in the blood.
