d another person take hold of the bottom of the frame
with one hand, so that his fingers touch the tin-foil, and with the
other hand attempt to take off the crown, he will receive a very smart
blow, and fail in the attempt. The operator, who holds the frame by
the upper end, where there is no tin-foil, feels nothing of the shock,
and can touch the face of the king without danger, which he pretends
is a test of his loyalty.

_The Cup of Tantalus._

You place a cup of any sort of metal on a stool of baked wood or a
cake of wax. Fill it to the brim with any liquor; let it communicate
with the branch by a small chain; and when it is moderately
electrified, desire a person to taste the liquor, without touching the
cup with his hands, and he will instantly receive a shock on his lips.
The motion of the wheel being stopped, you taste the liquor yourself,
and desire the rest of the company to do so; you then give your
operator (who is concealed in an adjoining room) the signal, and he
again charges the cup; you desire the same person to taste the liquor
a second time, and he will receive a second shock.

_Magical Explosion._

Make up some gunpowder, in the form of a small cartridge, in each end
of which put a blunt wire, so that the ends inside of the cartridge be
about half an inch off each other; then join the chain that proceeds
from one side of the electrifying battery, to the wire at the other
end, the shock will instantly pass through the powder, and set it on
fire.

_Artificial Earthquake._

In the middle of a large basin of water, lay a round wet board. On the
board place any kind of building, made of pasteboard, of separate
pieces, and not fastened together. Then, fixing a wire that
communicates with the two chains of the electrifying battery, so that
it may pass over the board and the surface of the water, upon making
the explosion, the water will become agitated as in an earthquake, and
the board, moving up and down, will overturn the structure, while the
cause of the commotion is totally concealed.

_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
