While here the _general_ electric influence is the main remedial agency, there is no reason why the possible—or, I should say, probable—good to be obtained from its _local_ influence should not be realized—the less so that it is so facile to obtain this in the bath, by means of the surface board. While individual cases will undoubtedly call for modifications, I have found the following plan to answer best in certainly more than half the cases that have come under my observation: The first five minutes of the bath may be occupied by a general galvanic current of medium intensity, _descending_ where the patient is of an irritable, _ascending_ where of a phlegmatic temperament. The pole connected with the foot electrode should now be detached, and the surface board substituted. The second five or ten minutes may be consumed by running a galvanic current between the head electrode and the surface board, the latter applied alternately to the penis, scrotum, perineum and, where thought best, also to the lumbo-sacral region. Where, as is usual, the impotency is accompanied by a certain degree of cutaneous anæsthesia of the penis, but especially where the seminal secretion is scanty, the board should be positive (ascending current); where however nocturnal spermatorrhœa, premature discharges (before coition is possible) or other irritable phenomena characterize a case, the surface board should be negative (descending current). The head of the patient should rest on a sponge thoroughly saturated with water, and communicating with the water of the bath, so as to include the cerebellum in the direct circuit. The last five or ten minutes of the bath should be devoted to passing the faradic current between the head electrode and the surface board, this last applied about the genitals, but chiefly about the perineum, the current to be of sufficient intensity to contract the perineal muscles. With anæmic patients iron should be added to the baths. These should be taken at first daily, later on every other day, then three times a week, and so on until it becomes apparent that all the good that can be obtained from them has been obtained—whether this be a perfect cure or only a certain degree of improvement. Where it is thought requisite, internal medication and various hygienic measures may be advantageously resorted to as adjuvants. While these will do no good when employed alone, they may serve to enhance the effects of the baths. In the following cases, I will include some where the impotency was not perfect, where the conditions were merely those of sexual debility. As there is here merely a difference in degree, it would be superfluous to separate the two conditions under distinct heads.
