The Magic Dance


From the middle of the brass arch suspend three small bells. The two

outer bells hang by chains, and the middle one by a silk string, while

a chain connects it with the floor. Two small knobs of brass, which

serve as clappers, hang by silk strings, one between each two bells.

Therefore, when the two outer bells communicating with the conductor

are electrified, they will attract the clappers and be struck by them.

The c
appers being thus loaded with electricity, will be repelled, and

fly to discharge themselves upon the middle bell, after which they

will be again attracted by the outer bells; and thus, by striking the

bells alternately, the ringing may be continued as long as the

operator pleases.



You next suspend a plate of metal from the same part of the arch to

which the bells are connected; then, at the distance of a few inches

from the arch, and exactly under it, place a metal stand of the same

size. On the stand place several figures of men, animals, or what you

please, cut in paper, and pretty sharply pointed at each extremity.

When the plate that hangs from the arch is electrified, the figures

will dance with astonishing rapidity, and the bells will keep ringing,

to the no small entertainment of the spectators.
