Effects of drugs on the hearts of Artemia salina (curves A, B, C, D, E), Eubranchipus serratus (curves F, G) and Diaptomus sanguinensis (curves //, 7). Ach, acetylcholine, Es, eserine, Adr, adrenalin. Heart rate in beats per affected by slight currents. Restraint in cotton or lens tissue was also ineffective. The best method found was to hold the specimens in a chamber supported by a variable number of coverslips as described above for Bactrurus. The specimens were placed in watch glasses containing approximately 10 ml. solution and were transferred from time to time to the restraining slides for examination. Prolonged restraint sometimes slowed the heart. Drug solutions were made up in culture fluid. The heart was easily seen from either dorsal or lateral aspect. Sometimes a margin of the heart was observed, sometimes the move-.
