To declare that a glandula1 product constitutes an internal secretion and as such has an effect upon the organism requires more than the mere recognition of its presence in the venous blood of the organ where it is formed; it must still be found in the blood of the left heart or in the blood of the general circulation; for it must pass into the circulation 1n order to reach the tissues upon which it shall act electively. Nothing proves a priori that the product found in the blood issuing from a gland issues into the general circulation; in fact, it might decompose or be rapidly destroyed in the mass of blood or else it might be diluted to a point where it would no longer have any effect It is, therefore, highly necessary that it should be found in the arterial blood if we are to affirm its hormonic hormozonic.
