ifference of potentials between the insulated conductor and the air at the place where the stream from the nozzle breaks into drops is done away with at the rate of five per cent, per half second, or even faster. Hence • a very moderate degree of insulation is sensibly as good as perfect, so far as… … siilplmric acid, to insure a degree of insulation in all weathers,by which there need not be more than five per cent, per hourlost by it from the atmospheric apparatus at any time. A littleattention to keep the outer part of the conductor clear ofspider lines is necessary. Theapparatus I employed…
