Thenceforth until he got nearly well he was obliged to use the catheter regularly. A few days after this, fortunately for himself, he fell down as he was leaving a horse car, and sprained his ankle. I say _fortunately_, for this accident _compelled_ him to remain at home. From this time he began to improve. December 2d I substituted for the ointment a twenty per cent solution of the oleate of mercury, of which he used a drachm morning and evening. The improvement from this day was exceedingly rapid. On the 4th of December he had regained control of the bladder. The constipation, which had been very obstinate, also began to yield. From this date he used the oleate only once daily, and discontinued it entirely on the 14th. On the 10th he had already resumed his avocation, and the same month absolutely danced at a ball. He took iodide of potassium for a time after his mercurial course. He has since been and is now in perfect health. DYSPEPSIA. The remedies for this disease are unfortunately so numerous, there is so much temptation to try another where one remedy has failed, that it is seldom or never that an uncomplicated case of dyspepsia applies for electrical treatment. As a rule, the disease that furnishes cause for referring a case to the specialist, is some nervous trouble secondary to the dyspepsia. In regard to the influence of electric baths on dyspeptic conditions, whether complicated or not, I can however speak unqualifiedly in their favor. I know of no one other remedy that can at all approach them in this respect. Whatever the secondary or other troubles of patients, any co-existing dyspepsia was in every instance either cured or greatly ameliorated. The improvement usually begins at once—after the first or second bath, and continues steadily. As I have not had occasion to treat by means of electric baths any uncomplicated cases of dyspepsia, I can adduce none. I may safely claim however for the baths a reliability and bespeak for them a confidence that I might claim or bespeak for no other remedy or plan of treatment whatsoever—assertions which would appear rash and venturesome, had I not at my command abundant clinical evidence to warrant my making them. MELANCHOLIA. A case of melancholia, highly illustrative of the effects in this condition of electric baths, came under my notice very recently. It may serve as a guide in the treatment of this and kindred conditions.
