An extra-renal action of thyroid has since been emphasised by several investigators. Ellinger [1922] laid stress on the influence of thyroxin on the swelling of plasma and tissue colloids, and was led to regard this substance as the prototype of diuretics with a primary extra-renal action. Asher [1920], Meyer- the thesisBisch [1923], and Fujimaki and Hildebrandt [1924] developed action of its action onof an extra-renal thyroid by studying general metabolism, on the formation of cedema fluid and on the state -of hydraemia. Moreover, Epstein [1929], from an investigation of the conflict of action of thyroxin and several narcotic substances on water- diuresis, favoured the exclusion of a renal component from the polyuric that noeffect of the hormone.
