The glass pil-lar carries on its upper extremity a crooked wire and ball, and a chainconnects the ball and nob of the jar. When the jar is charged, the glasspillar is moved round, until the ball it carries is above the one on thegable, when a discharge will take place, and the spark, in its passage,will throw the wire in the hole, b, from its place, producing an imitationof a stroke of lightning on a small scale.
