    above and below the horizontal diameter of the other two hollow rings, of which, for reason of their connection with those rub- bers, the interior conductor becomes Positively Electric. Those last two rings are connected by two conducting arcs, one above and one below, also communicating with their inside conductor; the upper one carries a long curved brass wire, provided with Fig. 4. a ball at each extremity, to conduct the Electricity where it is wanted. One of the first mentioned rings, which collect the Negative Electricity from the disk, carries a brass wire and ball, connected with the inside conductor, intended to carry the Neg- ative Electricity there where wanted. When the two balls, Posi- tive and Negative, are placed in the position represented in the figure, a long spark will pass over between them.
