There are sundry special applications of galvanism to particular forms of neuralgia which require a few words of notice. Of electrical treatment in regular angina pectoris I have had no experience; and in the one case of intercostal neuralgia, complicated with quasi-anginal attacks, in which I applied the constant current to the spine and the cardiac region, in the direction of the affected intercostal nerve, no effect was produced. I shall, however, mention the experience of Eulenburg, as he is a sober and dispassionate writer on the effects of electric treatment in general. He says he believes that in the proper use of the constant current we shall discover the chief, possibly the only direct, remedy for angina; and he describes the apparently favorable results he has already obtained in three or four cases. The current was from thirty cells; the positive pole was placed on the sternum (broad electrode), the negative on the lower cervical vertebræ. The alternative method which Eulenburg suggests, but has not, so far, put in practice, is direct galvanization of the sympathetic and vagus in the neck. The application of the constant current in neuralgic affections of the larynx and pharynx is of most indisputable service; the experience of Tobold[45] upon this point is fully borne out by my own, as far as it goes. In many cases it will be sufficient to place the positive pole (from fifteen cells Weiss) on the pomum Adami, and the negative on the nape of the neck, and to keep up a continuous current for five or ten minutes daily; but in some cases the direct application of the current to the pharynx or larynx may be required; in such, a modification of Dr. Morell Kackenzie's laryngeal conductor will be found useful. [I shall have occasion, in Part II., to notice the superior action of Faradization in mere hysteric throat-pain, as distinguished from true neuralgia.] Neuralgia of the testicle can be best treated, if galvanism be thought necessary, by immersing the whole scrotum in a basin of salt and water, in which the positive pole is placed: the negative pole is to be placed on the upper lumbar vertebræ; the current should be from fifteen cells Weiss, and the application should last continuously for ten minutes. In neuralgia of the urethra, I should be inclined to adopt a plan, mentioned to me by Dr. Buzzard, of attaching one conductor to an ordinary silver catheter introduced into the urethra, and placing the other pole upon the perinæum. Neuralgia of the neck of the bladder I have found to be materially relieved by the constant current from twenty cells passed through from pubis to perinæum; the sittings being rather long. I have also, on one occasion, tried the introduction of a proper _porte-electricite_, insulated, except at the tip; but the result was not superior to that obtained in the other way.
