We have long been accustomed to use these covers in all mildcentral applications of the galvanic current. A Current-Re%!erser with Flexible Electrodes,—Fig. 95 represents acurrent-reverser which was first constructed by Messrs. Tiemann & differs mainly in this feature from other devices to accomplish thesame purposes, viz.: that the current is reversed by simple and slightpressure of the thumb, without the intervention of a slide, or any com-plex arrangement whatsoever. The letter D represents the button of the spring, by pressing which,the current is interrupted or reversed. Pressing it lightly interrupts thecurrent; pressing it firmly reverses Fig. 95.—CuiTent-Reverser, with flexible electrodes. In the vertical section of the hard-rubber handle, A A is representedas springing up against the metallic plate on the upper and inner surfaceof the handle. Pressing this slightly down, metallic connection is brokenand the current is interrupted; pressing it firmly down, the connection ismade and reversed at B B, the metallic plate on the lower surface ofthe handle. C represents the wires that connect with the battery, enclosed in a rub-ber tubing E. F and G are flexible wire electrodes armed with sponges; they can beseparated several inches and kept there, or put close together as repre-sented in the cut. The advantages of this are these: i. In many of theapplications of localized electrization this neat and simple arrangementsaves considerable expenditure of muscle on the part of the operator. Onehand can be perfectly free while the other holds and guides the electrizing
