As to the shock caused by the electric current toward the ear, it has been clarified, by Oda, Wittmaack, Minami as well as myself, that there appear certain different histological changes on maculae acustica at either anode or cathode. From this, one could imagine that positive as well as negative electric current give certain stimulus quite contradictory toward maculae acustica. Then, if certain electric stimulus of same pole and same intensity are administered to both the ears simultaneously, one might surmise that certain utterly different stimulus (control or excite) would be given on both maculae acustica, under either positive or negative current. If any rotatory stimulus is added (which is a pure stimulus for the maculae acustica), it may be supposed that pictures contrary to each other might appear in its compensatory eye deviation, according to the kind of current which is either positive or negaive. Having activated 2 M. A. same pole current on a rabbit's both ears (laying indifferent electrode on the back) I fixed it on the rotatory table invented by Hoeve and de Kleyn and photographed rotatory eye deviation. Unluckily, in my experiment, I failed to recognize any difference in the eye deviation between positive or negative current. However, as I thought the method to be interesting, I have recorded it duly.
