    old aural disease, extensive destruction of the middle ear, and labyrinthine trouble. Qualitative Anomalies of the Galvanic Reaction of the Auditory ivithout HyjyercBsthesia.-—The anomalies in question are those that have just been described. They are of every conceivable variety. They appear to depend upon nutritive errors, and they may be due also to the action of vertical replacing the actual poles in cases where structural changes have determined new paths for the current. They are met with in severe and inveterate ear disease, in rheumatic facial paralysis, and in central disorders. Torpor of the Auditory Nerve.—This is a condition of diminished excitability (Donne) in severe and in- curable disease, in which for the most part the precise connection with structural changes is not apparent. Electrical Treatment of Tinnitus Aurium.—From what has been said in the preceding paragraphs, it will appear that the behaviour of the auditory nerve to galvanic currents is apt to vary very greatly, and it is unnecessary to insist that the appropriate treatment must depend upon the result of a previous investiga- tion in each case. It is impossible to lay down rules for all It is obvious that where the purpose is to allay subjective noises this may best be done by repeated application of the stimuli which are found by experi- ment to exercise a soothing effect, and where unusual difficulties are encountered treatment should be left to those whose experience has provided them with special skill In this place will be described the method of treatment which is most useful in the greatest number of curable cases—the typical condition being that in which subjective noises of nervous origin accompany a simple galvanic hypersesthesia without a change of formula. In respect of prognosis there is no difficulty. Those cases will be benefited in which it is found that the noises disappear or diminish under treatment. Others will not be benefited, with the exception, perhaps, of certain cases of rheumatic facia] paralysis in which electrical treatment may affect the primary disease.
