from the
hook of the full phial.

The Abbé says, p. 103, "That a piece of metal leaf hung to a silk
thread and electrised, will be repelled by the bottom of a charged
phial held by its hook in the air:" this I find constantly otherwise,
it is with me always first attracted and then repelled: it is
necessary in charging the leaf to be careful, that it does not fly
off to some non-electric body, and so discharge itself when you think
it is charged; it is difficult to keep it from flying to your own
wrist, or to some part of your body.

The Abbé, p. 108, says, "that it is not impossible, as Mr. Franklin
says it is, to charge a phial while there is a communication formed
between its coating and its hook." I have always found it impossible
to charge such a phial so as to give a shock: indeed, if it hang on
the conductor without a communication from it, you may draw a spark
from it as you may from any body that hangs there, but this is very
different from being charged in such a manner as to give a shock. The
Abbé, in order to account for the little quantity of electric matter
that is to be found in the phial, says, "that it rather follows the
metal than the glass, and that it is spewed out into the air from
the coating of the phial." I wonder how it comes not to do so too,
when it sifts through the glass, and charges the exterior surface,
according to the Abbé's system!

The Abbé's objections against Mr. Franklin's two last experiments, I
think, have little weight in them: he seems, indeed, much at a loss
what to say, wherefore he taxes Mr. Franklin with having concealed a
material part of the experiment; a thing too mean for any gentleman
to be charged with, who has not shown as great a partiality in
relating experiments, as the Abbé has done.

My hopes of success, which I imparted to him, were founded on the circumstance, that the only paper we had in Philadelphia at that time, and which Bradford printed, was a paltry thing, miserably conducted, in no respect amusing, and which yet was profitable.

He endeavoured to account for this, by supposing that, from heat, some rarefaction takes place about the gulph of Mexico, that the air further north rushes in, and is succeeded by the cooler and denser air still farther north, and that thus a continual current is at length produced.

but no alteration was made at all, nor could I perceive that the steam was itself electrised, though I have still some suspicion that the steam was not fully examined, and I think the experiment should be repeated.

--But having since found, that salt in the water of an electric phial does not lessen the shock; and having endeavoured in vain to produce that luminous appearance from a mixture of salt and water agitated; and observed, that even the sea-water will not produce it after some hours standing in a bottle; I suspect it to.
