Abstract
1. 1. Para-ethylaminobenzoate (benzocaine) reduced the rate of electric organ discharge in the transparent knifefish, Eigenmannia virescens, without altering the amplitude of individual pulses. 2. 2. A high concentration of benzocaine, 0·2 m M, always depressed the discharge frequency by about 50 per cent initially, and then suddenly and abruptly abolished the remaining level of electromotor activity completely. 3. 3. Following the total cessation of electric organ activity, and after the removal of benzocaine, recovery of the frequency of firing was rapid but was accompanied by a brief period during which the amplitudes of individual pulses were severely distorted.
