a balance board were described. In my series of normal persons, generally from 1 to 3 milliamperes of galvanic current and rarely 5 milliamperes was necessary to produce falling. Labyrinths inactive to caloric stimulation failed to react to a large amount of galvanic current (20 milliamperes).Of the sixty-three patients examined for hearing, fifty-five (87 per cent) responded normally. This compares well with the results of Langdon,2 who reported normal hearing in 85 per cent of thirty-five patients with epilepsy, and differs from those obtained by Jones,3 who found no cochlear defects in twenty-seven such patients.In twenty-nine patients, nine with organic and twenty with functional epilepsy, tested for galvanic falling, caloric nystagmus, past pointing, and hearing, eighteen (62 per cent) were found to have normal vestibular and auditory functions. In sixty-one patients tested for hearing, vestibular function was determined by caloric nystagmus, galvanic falling or both; forty-five (73.7 per cent) reacted with normal vestibular and auditory responses. Sixteen were classified as having abnormal vestibular function because of falling produced by 0.5 milli-Otologist to the

The reactions of experimental animals and of human beings to stimulation with the galvanic current have been investigated since early in the nineteenth century. Not only the reactions of normal subjects, but the reactions of animals and human beings with all types of experimentally produced and spontaneous lesions have been the subject of numerous investigations. Experiments on the latter group were carried out in an attempt to establish galvanic stimulation as a clinical procedure which might replace, or at least serve as an adjunct to, performance of the caloric and the rotation test for vestibular function.Nystagmus, postural reactions, such as turning and rotation of the head, subjective vertigo and a tendency to fall have all been observed as a result of galvanic stimulation of the ears. The nystagmus has received more attention than the other reactions, because of an attempt of the investigators to correlate the galvanic reaction with the reactions elicited by caloric and rotatory stimulation. The direction of the postural reaction in normal subjects has been established as toward the anode; i. e., if the anode was in contact with the right ear, the head was turned toward that side and rotated so that the right ear was lowered. There was also a tendency for the subject to fall to the right.Ritter 1 was apparently the first author to investigate the effects of galvanic current in the production of vertigo. He was particularly interested in the amounts of current necessary to elicit responses of various kinds in persons of different age and sex.
