Last, but not least, I have some remarks to offer on the treatment by the electric bath of certain affections of the sympathetic nerve. While I do not in any such cases accord to the baths the rank of an exclusive remedy or even a specific, their importance as an adjuvant is sufficient to entitle them to special consideration in this connection. In those neuroses of the sympathetic where electricity (galvanism) is indicated, the _greatest_ benefit can be obtained from local applications. On the other hand the baths, employed in addition to local applications, will be found a very important factor in the treatment, possessing, as they do, two advantages, viz: _first_, by their means, the electric influence is brought to bear—in a much less concentrated form it is true—on the entire sympathetic system, from the _ganglion impar_ to the _ganglion cervicale supremum_, and, by derived currents, on the cephalic ganglia also, at one and the same time; _second_, the rest of the body participates in the general nutrient and tonic effects of the bath equally with the sympathetic, the latter thus receiving a reflex benefit which local applications fail to furnish. There are, moreover, cases where hyperæsthetic conditions of the nerve do not admit of local applications, and where yet electricity is urgently called for. Thus I have at present under treatment a lad sixteen years of age, in whom both supreme cervical sympathetic ganglia as well as the ganglion impar were until recently so susceptible that the mere adjustment of the electrodes caused him great pain, while on the other hand he bore the baths exceedingly well. In such cases, electric baths, suitably administered, frequently constitute in conjunction with proper medication, the most useful treatment. As to the mode of administration in sympathetic neuroses of the baths, the most direct manner in which to influence the diseased nerve, is by connecting one pole of a _galvanic_ battery (I consider the faradic current next to useless here) to the head electrode, the other to the surface board, the latter applied portion of the time to the epigastrium (solar plexus), the balance to the coccyx (_ganglion impar_). This will include in the direct circuit the main portion of the sympathetic, the position in the tub of the bather bringing the cilio-spinal centre very close to the head-electrode. The direction of the current must be determined by the individual features presented by each case, as also the duration of the bath.
