members of the Society had themselves drawn down lightning from the clouds,
it elected Franklin a member, and, in view of the fact that the honor had
not been sought by him, voted that he "was not to pay anything"; which
meant that he was to be liable for neither admission fee nor annual dues,
and was even to receive his copy of the Transactions of the Society free of
charge. Nor did it stop here. It also awarded to Franklin, for the year
1753, the Copley gold medal, accompanied by an address, in which Lord
Macclesfield, its President, endeavored to make full amends to him for its
belated recognition of the value of his discoveries.
The suggestion by Franklin, which led to the experiments of D'Alibard and
De Lor, is as matter-of-fact as a cooking recipe.
To determine the question [he said in a letter to Peter
Collinson] whether the clouds that contain lightning
are electrified or not, I would propose an experiment
to be try'd where it may be done conveniently. On the
top of some high tower or steeple, place a kind of
centry box,... big enough to contain a man and an
electrical stand. From the middle of the stand let an
iron rod rise and pass bending out of the door, and
then upright 20 or 30 feet, pointed very sharp at the
end. If the electrical stand be kept clean and dry, a
man standing on it when such clouds are passing low,
might be electrified and afford sparks, the rod drawing
fire to him from a cloud. If any danger to the man
should be apprehended (though I think there would be
none), let him stand on the floor of his box, and now
and then bring near to the rod the loop of a wire that
has one end fastened to the leads, he holding it by a
wax handle; so the sparks, if the rod is electrified,
will strike from the rod to the wire, and not affect
him.
