The exposed end shouldbe about half an inch to one inch in length, and made of Electro-Surgery 253 platinum, gold, or carbon ; the stem may be made ofcopper, carefully insulated by vulcanite. Apostoli nowuses gas carbon electrodes ; a metallic stem, insulated bycaoutchouc, bears a screw at one extremity, to which rodsof gas carbon, all one inch in length, but of differentdiameters, can be attached. The caoutchouc coveringis marked with grooves at regular distances of one inch(Fig. 123).For galvano-puncture a sharp-pointed steel trocar sliding

Preparation of the Apparatus. Connect the rheophore coming from the positive pole ofthe battery to one of the binding screws of the rheostat,and a wire passing to the galvanometer to the other(Fig. 126) ; let them be on a firm table ; then attach along wire intended to reach the uterine sound to the otherterminal of the galvanometer. Let the rheostat be screwedout to its full distance. Attach the other rheophore to the 254 A Manual of Practical Medical Electricity negative pole of the battery. Turn on all the cells, andplunge the ends of both terminal wires into a vessel ofwater, taking great care not to allow them to touch. Gasshould now be pretty freely given off, and in much largerquantity from the negative terminal. This decides twoquestions—whether all the cells are properly connectedand in wo
