It consists in placing a bromo-iodide of silver paper on a spotted metallic plate, pressing the same down by means of a glass, and passing sparks from a powerful Leyden jar along the metallic plate. Each break in continuity of the metallic surface causes a spark which discolors the paper at this point.
