CASE XXI. _Sciatica._ Mr. G., aet. about 35, saddler, was sent by Dr. WAECHTER, March 6th, 1875. Had suffered from sciatica without discoverable cause for several years. For one year prior to his visit had been unable to work, and was confined to bed a great portion of the time. There was slight atrophy of the affected limb. He had had considerable medical (including local electrical) treatment, without avail. The baths were faithfully and persistently tried in this case, effecting however but slight improvement. Subsequent hypodermic injections, first of strychnia, then of atropia and finally of chloroform, the latter in doses ranging from 30 to 60 minims, gave him only temporary relief. The patient was finally discharged uncured. CASE XXII. _Lumbo-abdominal neuralgia._ Mr. W., aet. about 40, was brought by Dr. MARVIN S. BUTTLES in June, 1875. He had been in poor health for a number of years, and was then in a very cachectic condition. There was considerable gluteal atrophy on the affected side. At Dr. B.’s suggestion he took a course of electric baths, with the happiest result. He improved steadily, and on the occasion of a late inquiry after I had not seen him for some months, Dr. B. told me that the patient had entirely recovered. His general condition as well as the neuralgia had been very favorably modified by the baths, and he is now in far better health than he has been for many years. CASE XXIII.—_Lumbo-abdominal neuralgia._ Mr. G., aet. 40, came to consult me in October, 1875. He had suffered from neuralgic pains, more particularly in the renal region of both sides, but also in the neighboring parts, for only one week. The case being so recent, I entertained a very favorable prognosis, which subsequently was amply verified. A bath on the 12th of October and one on the 16th sufficed to effect a complete cure. ARTICULAR EFFUSIONS. It would appear at a first glance as though local galvanization of affected joints should be more directly and powerfully instrumental than electric baths in promoting the absorption of morbid deposits. To suppose so would however be a mistake—even where a single joint is concerned. Where many joints are involved, the advantages over local galvanization of the baths is sufficiently obvious. Where but a single joint is involved, the current can by means of the surface board be concentrated on the affected joint, while by the general galvanization a stimulus is furnished to the absorbents, that in itself is probably fully as important as any local treatment could be. In this manner absorption is made to progress much more certainly and rapidly, and this course is therefore to be given the preference in all cases where no special contra-indication exists.
