AN EXPERIMENTAL STUDY OF BLOOD GLYCOLYSIS. THE EFFECTS OF THYROID AND ADRENAL EXTRACTS AND PHLORHIZIN ON GLYCOLYSIS IN VITRO.

1. Blood glycolysis in vitro during a period of three hours' incubation proceeds at practically the same rate under sterile conditions and when no effort is made to prevent contamination. 2. Fresh thyroid extract, adrenalin, and phlorhizin do not contain any substances which have a constant effect upon the rate of blood glycolysis outside of the body. No evidence of the presence of an antiferment was found.
