title: THE SELECTIVE ACTION OF NICOTINE ON THE CENTRAL NERVOUS SYSTEM OF THE SQUID, LOLIGO PEALII.
abstract: 1. In specimens of freshly hatched squid, Loligo pealii, nicotine acts upon the cerebral ganglia alone. 2. After 1 minute in the nicotine solution 1:500,000, the latent period for the mantle spasm is independent of the time spent in the solution. 3. The mantle spasm is conditioned by a chemical reaction, since the temperature coefficient of the process has a magnitude of about 2.8. 4. The velocity of the process which brings about the mantle spasm varies as the cube root of the concentration of the nicotine.
