1. The hormonal coordinating mechanism of the sexual process in Achlya is briefly reviewed. 2. A technique is described for culturing the female plant of Achlya bisexualis in sufficient quantity to furnish material for the chemical study of hormone A. 3. A modification of the biological assay for hormone A is described. 4. Many of the properties of hormone A have been determined: (a) solubilities in common organic solvents, (b) adsorption, (c) stability, (d) inactivation, and (e) reactions with certain reagents. 5. A procedure is described whereby enormous enrichment of the active principle has been achieved.
