Experiments and Observations on Electricity Made at Philadelphia in America

given s 10. We made also of large glass panes, magical pictures, and
self-moving animated wheels, presently to be described.

19. I perceive by the ingenious Mr _Watson_'s last book, lately received,
that Dr _Bevis_ had used, before we had, panes of glass to give a shock;
though, till that book came to hand, I thought to have communicated it to
you as a novelty. The excuse for mentioning it here, is, that we tried the
experiment differently, drew different consequences from it, (for Mr
_Watson_ still seems to think the fire _accumulated on the non-electric_
that is in contact with the glass, page 72) and, as far as we hitherto
know, have carried it farther.

20. The magical picture is made thus. Having a large metzotinto with a
frame and glass, suppose of the KING, (God preserve him) take out the
print, and cut a pannel out of it, near two inches distant from the frame
all round. If the cut is through the picture 'tis not the worse. With thin
paste or gum-water, fix the border that is cut off on the inside of the
glass, pressing it smooth and close; then fill up the vacancy by gilding
the glass well with leaf gold or brass. Gild likewise the inner edge of the
back of the frame all round except the top part, and form a communication
between that gilding and the gilding behind the glass: then put in the
board, and that side is finished. Turn up the glass, and gild the fore side
exactly over the back gilding, and when it is dry, cover it by pasting on
the pannel of the picture that had been cut out, observing to bring the
corresponding parts of the border and picture together, by which the
picture will appear of a piece as at first, only part is behind the glass,
and part before.--Hold the picture horizontally by the top, and place a
little moveable gilt crown on the king's-head. If now the picture be
moderately electrified, and another person take hold of the frame with one
hand, so that his fingers touch its inside gilding, and with the other hand
endeavour to take off the crown, he will receive a terrible blow, and fail
in the attempt. If the picture were highly charged, the consequence might
perhaps be as fatal as that of high-treason; for when the spark is taken
through a quire of paper laid on the picture, by means of a wire
communication, it makes a fair hole through every sheet, that is, through
48 leaves, (though

Franklin, however, was in all of his researches under a self-confessed yoke which doubtless tended to deny him access to the profoundest reaches of scientific inquiry: from Philadelphia he wrote in 1753 to Cadwallader Colden, eminent mathematician (as well as versatile scientist): "Your skill & Expertness in Mathematical Computations, will afford you an Advantage in these Disquisitions [among them, researches in electricity], that I lament the want of, who am like a Man searching for some thing in a dark Room where I can only grope and guess; while you proceed with a Candle in your Hand.

It was well receiv'd by the common People in general; but the Rich Men dislik'd it; for it increas'd and strengthen'd the Clamour for more Money; and they happening to have no Writers among them that were able to answer it, their Opposition slacken'd, and the Point was carried by a Majority in the House.
