Adrenalin chloride (Parke, Davis & Co.) and chromaphil tissue extracted in distilled water were added to the bath by means of a pipette. Control tests, in which similar amounts of distilled water and extracts of liver and spleen were added to the bath, showed that the method was satisfactory. An extract of the anterior chromaphil bodies was made in one cc. of distilled water immediately on removal of the tissue, and used at once. In a few cases, in which R. stabuliforis served as a source of chromaphil tissue, only one "axillary heart" was used to one cc. of distilled water,. FIG. 1. Effect of adrenalin chloride, 1 in 50,000, on the pyloric portion of the stomach. Time in 5 second intervals. A, Raia erinacea. Typical effect on tonus. B, R. diaphanes. Effect mainly on motility. but in the case of the smaller species of Raia both anterior chromaphil bodies were used and sometimes, in addition, some of the accessory bodies. In the experiments in which the extrinsic nerves were stimulated the entire central nervous system was pithed. The left vagus was exposed through the anterior cardinal sinus. The first sympathetic.
