Electro-physiology and electro-therapeutics : showing the best methods for the medical uses of electricity / By Alfred C. Garratt.

this last-mentioned period, ice may be certain that the cure is definite. When they do thus return, the application must be repeated as strong as can be borne, when the pain will be found to become feebler after each seance. If, however, after two or three fair trials, success has not in any degree attended them, the application must be renounced. The conditions for success of Faradaization with electro-magnetism are, the recent date, the diffusion, the superficial seat, and the moderate intensity of the pain. Still, as there are cases in which, though the pain lias been there of old date, and success from this treatment in such has taken place, it should always be tried, for it is certainly with some chance of benefit. As a general rule, hysterical females bear the sharpest Faradaization with far more courage than men; but still some of them are so exquisitely susceptible, that its em- ployment, if urged upon them, may even induce paroxysms of hysteria. In such cases it is recommended to let her pre- viously inhale ether, as it in no wise impedes the peculiarly re- vulsive action of Faradaization. During the treatment of this affection, one grand condition must be, the complete repose of the hypcrassthetic muscles. This is, under all circumstances, of prime necessity. From ignorance of the true nature of this affection, exercises of various kinds have, from time to time, been recommended! Absolute repose is one essential to the cure; and a few days of such, sometimes, is of itself sufficient to relieve those pains that have resisted most energetic reme- dies. There should be a general or medical treatment, there- fore, as well as the "electrical." (See p. 475, and Appendix.) Neuralgia. M. Valleix was the first to point out the great fact, as regards true neuralgic affections, and which seemed to have escaped the notice of all previous medical observers and that was, that the superficial nerve trunks, and those that emerge from bony canals, are those most commonly affected ; also, that there are certain other "painful points" in the course of a nerve which are more liable to be affected by this kind of pain than any
