Place a man on a cake of wax, and present him the wire of the
electrified phial to touch, you standing on the floor, and holding
it in your hand. As often as he touches it, he will be electrified
_plus_; and any one standing on the floor may draw a spark from him.
The fire in this experiment passes out of the wire into him; and at
the same time out of your hand into the bottom of the bottle.
