A proverb assures us that a teller of untruths should be skilled in
mnemonics.
We exclaim, quite apropos of this remark, that we have a mystic harp
which retains for our pleasure the airs which it has heard or played.
Amidst the murmur of incredulity, take the lyre and hang it to a wire
luckily pendent from the ceiling.
On the unbeliever placing his ear close to it, the air is heard as of a
whole band, at a distance, brilliant in its minuteness.
_Explanation._—In the upper room is a piano, a square or grand being
preferable: a wire runs directly from its sounding-board to the room
below where the lyre is suspended. For convenience, the wire can be bent
or formed of several portions overlapping where the join occurs.
