the course of the nerves very accurately in the dissecting-room and observing their points of entrance into, and their course within, their muscles, with constant reference to the surface of the body; but he was not completely satisfied until he had determined the motor points upon the skin immediately after death, and before the reaction to electricity had disappeared, and submitted these points to the scalpel. The results of the three methods coincided perfectly. [SN: Cutaneous Electrization.] We will next consider cutaneous electrization. I have already shown you that when the skin and the conductors are both quite dry, a Faradaic current of moderate power (and practically this form of electricity is always employed in cutaneous electrization) does not penetrate the skin, but is localized upon its surface. There are three methods of applying cutaneous Faradization--the method that we employed--that of “_Metallic Conductors_;” the “_Electric Hand_,” as it is called, in which the operator having applied one conductor to some little sensitive part of the patient’s body, holds the second in his left, and passes the back of his right hand over the points he wishes to excite, these points of the patient’s skin and the back of his hand being dry, and sprinkled with absorbent powder; and the “_Wire Brush_,” a brush of metallic wire, which replaces one of the conductors, and which is moved over the skin. With a strong Faradaic current this wire brush becomes the most powerful of all the excitants of the skin which do not disorganize its structure; in fact it was proposed by some scientific parliamentary philanthropist as a substitute for flogging in the navy, and I have no doubt that more intense pain may be produced by it than by any application of the cat, however well laid on! [SN: Electrization of Internal Organs.] The methods of electrizing internal organs need not detain us long. The rectum and muscles of the anus may be electrized by introducing into the rectum the rectal rheophore, a metallic stem insulated by gum elastic, and moving it over the internal surface, bringing it also into contact with the levator and sphincter ani. A well-moistened sponge connected with the other pole may be applied to the abdominal muscles or to the neighbourhood of the anus. The rectum must be first freed from fæcal matter.
