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

current is great, or is interrupted, or reversed; neither of which is under any circumstances allowable. True, I cannot speak from any satisfactory treatments of my own, as yet; but from what I have observed, I certainly should apply the primary direct current of galvanism to such a case, and perhaps a very gentle, even, and long-continued current of electro-magnetism, down the spine, and from the coccyx down to the foot, if the first cause had not been there situated. Hysterical convulsions, cramps, and rigidities are proper cases for the electrical treatment, and are usually benefited by it. Sometimes, and that not seldom, the exalted hysterical phe- nomena are quite annihilated by this means, so that these cases may be said to be permanently cured. In these variegated affec- tions, the testimony of Dr. Becquerel, as also of Drs. Meyer, Remak, and others of high authority, goes to show the uniformly good effects of electric currents in all such cases, when well directed; and this is as might be expected, because neither the motor nerves, nor the cerebro-spinal axis are in any way injured. But here we must never employ sparks, shocks, nor interrupted or reversed currents. Treat all such cases as if neuralgia, by running the primary or very even and gentle secondary current doion the spine, or down the abdomen or limb at first; then try to bring both electrodes below or beyond the site of the cramp, with a very carefully managed direct current cautiously ap- plied, long retained, and as carefully removed. (See P, Note 2.) Agitans, or " tremblings " from the poison of alcoholic drinks, as more frequently seen after delirium tremens, — muscle and limb tremblings from the poison of mercury, opium, lead, or arsenic, — and the tremblings of exhausted muscles, as from pro- tracted monotonous work, or from premature old age, are greatly benefited by bathing all such extremely enfeebled nerves and muscles or limbs with a brisk current of Faradaism. To this end, employ the team electrodes by ceaseless (labile*) movements, and this to be followed by the gentle frictions, strokes, and smoothings of the palms of the hands ; then cover with fur or flannel. If this is carefully performed daily, yet not overdone, the restoration is remarkably uniform, speedy and complete. 51*
