The literature covering the normal galvanic reaction in animals and in human beings has been reviewed in a previous report;1 a method of studying the reaction in guinea pigs was described in the same report.
Many investigators have concerned themselves with the question as to whether the galvanic reaction is altered by disease of, or mechanical destruction of, the labyrinth. Ewald2 carried out research on pigeons after unilateral and bilateral labyrinthectomy. He reported that in an animal with both inner ears completely destroyed high currents caused no turning of the head. In a pigeon that has had unilateral labyrinthectomy, if the anode was placed on the labyrinthectomized side and the cathode on the sound side there ensued turning of the head toward the anode and rotation of the head in the same direction, both of which reactions increased with increase in the strength of the current.
