Summary The reactions of small traces of acetylcholine are investigated at the lungs of frogs, perfused with Ringer solution. Under favourable conditions and nicotinamide added to the perfusing fluid, 102–104 molecules of acetylcholine cause a constriction of the vessels and a contraction of the smooth muscle fibers of the lungs.
