On the contrary, we sometimes see complete failure of the current to affect any good whatever; and in these cases the reversal of the current has not, so far, appeared to me to make any particular change in the result. Such was the case with a patient whose history I detailed (along with that of Case I.) to the Clinical Society. She was an ill-fed and overworked unmarried needle woman, aged thirty; the neuralgia was a most violent double occipital pain, with foci, on each side, where the great occipital nerves become superficial. The current was passed daily, for some days, from one focus to another (necessarily passing through the nerve-roots and the spinal cord), and the positions of the conductors were occasionally reversed; this not succeeding, the current was applied altogether to the spine, the negative pole being placed on the highest cervical vertebræ, but no good effect was produced after a treatment, altogether, of sixteen days. Notwithstanding these, and a good many similar facts that could be adduced, I should hesitate to go so far as to say that there is never any importance in the direction of the current. In old-standing cases, where there are well-marked _points douloureux_ that are exceedingly sensitive, I have found that the application of the positive pole, successively, on the most tender points, the negative being placed on the spine opposite the point of origin of the nerve, has had a more beneficial effect than any other mode of application. There are very considerable differences, both as to the best manner of galvanization, and also as to the chances of doing good with it, in the case of neuralgias of different nerves; and, on the whole, I find Eulenburg's conclusions on this matter very just. He indicates sciatica as the affection which is by far the most curable by the constant current; he says that many cases are cured in from three to five sittings, while others require as many weeks, or even months of treatment; and that a total absence of benefit is only seen in rare cases dependent on central causes, or on diseases which are irremovable (like malignant pelvic tumors). On the other hand, he reports that intercostal neuralgia has never been materially benefited by galvanization in his hands. With regard to ordinary trigeminal neuralgias, he speaks strongly of the current as a palliative, but very doubtfully of its power to cure, in genuine and severe cases. In cervico-brachial neuralgia he speaks of it as dividing with hypodermic morphia the whole field of useful treatment, in the majority of cases. In cervico-occipital neuralgia he says it rarely does much good. I shall return to Eulenburg's estimate of its utility in migraine, presently. Let me here say that I am inclined to indorse everything in the above-detailed statements, excepting that I should place a considerably higher estimate on the curative powers of the current in ordinary trigeminal neuralgias. The remedy, like every other, will doubtless fail
