As a general rule, it may be said that electricity, like other local measures which tend to concentrate the patient's attention on the parts, is only to be applied to the genital organs as a last resort. This is, of course, especially true in the neuralgias of these organs in women. In concluding what will doubtless seem to some English readers an over-long and over-favorable estimate of the employment of galvanism in neuralgias, I must carefully guard myself against the supposition that I consider it a remedy to be applied in all cases, or likely to meet with uniform success, even in the forms of the disease to which it is most appropriate. It is a weapon which I seldom employ in the first instance, for many reasons; the principal of which is the costliness of the proceeding to the patient. Either the physician must personally administer the remedy, daily, often for a considerable period, or he must make the patient provide himself with an expensive battery; and in the latter case there is, after all, the unsatisfactory consideration that the application (even after the most careful directions have been given) will perhaps be unskilfully and inefficiently made. On the other hand, it is not desirable to delay the employment of galvanism too long, if other remedies have been fairly tried; and the practitioner will do well to remember the distinctions above laid down as to the varieties of neuralgia in which it is specially likely to prove decidedly and quickly beneficial. More especially in sciatica it would really, with our present knowledge, be a decided neglect of duty were we to allow the disease to run any considerable length without giving the constant current a thorough trial. [I can only briefly refer, here, to the novel mode of galvanization introduced by Dr. Radcliffe, and based upon his ingenious theory, according to which the true effects of the voltaic current upon nerve are the result of the charge of free electricity which it sets up, and not of the current directly. The reader will find the whole argument elaborately worked out in Dr. Radcliffe's recent work on "The Dynamics of Nerve and Muscle," Macmillan & Co., 1871. It will be enough to say, here, that the object to be attained, according to this view, is to replace the neuralgic nerve in its healthy physiological state, by charging it with free positive electricity. The manner in which this is done is as follows: In a case, _e. g._, of cervico-brachial neuralgia, we place the positive pole as near as may be to the central origin of the affected nerve; the negative pole is held in the hand of the same side, which is immersed in a basin of warm salt and water. In this same basin is another electrode, the wire from which is put in communication with the earth--most conveniently by putting it in contact with a gas-pipe. The patient, and the battery, ought properly to be insulated. The result of this arrangement is, that the free
