ERGINE, C16H17ON3, the amide of lysergic acid, is the simplest of the ergot alkaloids. It forms salts with hydrochloric and hydrobromic acids, and crystals of these were kindly put at our disposal by Prof. A. Stoll, of Basle. Both salts crystallize in elongated colourless plates, which are optically biaxial positive with the plane of the optic axes perpendicular to the b-axis.
