To each of the extremities of thesebranches is attached a small sponge electrode. Theseelectrodes are insulated by means of hard rubberplates. To each of the electrodes is attached a con-ducting cord. These cords unite in one common stem,which being secured to the binding post of a galvanicbattery renders the polarity of the two sponge elec-trodes the same. (Fig. 1
