1. Thyroid activity was studied with 131I injected intraperitoneally. The uptake of 131I was followed in the living animal. The animals were brought into a state of hypoxic hypothermia by Giaja's method .
2. The thyroid gland is completely inactive at body temperatures of between 15 and 20° C.
3. At body temperatures of between 23 and 28° C, thyroid activity is decreased, but is large enough, over a sufficiently long period of time, to concentrate normal quantities of iodine.
4. Thyroid activity is unchanged when a normal body temperature is regained after a single or four to six successive phases of hypothermia.
