In the preceeding paper (this journal 2, 345 (1953)) these authors described an apparatus of regulating circuit consisting of galvanometer switch-amplifier-electromagnetic relay-reversible motor, which used direct current as an electrolysis source. In the present paper, a new sensitive potentiostat employing galvano-meter switch-A. C. amplifier-reversible motor is described and also some results of using it are given. This instrument is completely line-operated from 110 volts alternating current source except one 1.5 volts dry battery as a supplement for cathode potential; no regulation is necessary before use and the potential of working electrode is kept automatically definite during the electrolysis. The working capacity for electrolysis is 30V and 3A, and the sensitivity to the change in electrolysis is about ±7 mV.
