offended the Abbe Nollet, preceptor in Natural Philosophy to
the royal family, and an able experimenter, who had formed and published
a theory of electricity, which then had the general vogue. He could not
at first believe that such a work came from America, and said it must
have been fabricated by his enemies at Paris, to oppose his system.
Afterward, having been assured that there really existed such a person
as Franklin at Philadelphia (which he had doubted), he wrote and
published a volume of letters, chiefly addressed to me, defending his
theory, and denying the verity of my experiments, and of the positions
deduced from them. I once purposed answering the abbe, and actually
began the answer; but, on consideration that my writings contained a
description of experiments which any one might repeat and verify, and,
if not to be verified, could not be defended; or of observations offered
as _conjectures_, and not delivered dogmatically, therefore not laying
me under any obligation to defend them; and reflecting that a dispute
between two persons, written in different languages, might be lengthened
greatly by mistranslations, and thence misconceptions of another's
meaning, much of one of the abbe's letters being founded on an error in
the translation, I concluded to let my papers shift for themselves,
believing it was better to spend what time I could spare from public
business in making new experiments than in disputing about those already
made. I therefore never answered Monsieur Nollet, and the event gave me
no cause to repent my silence; for my friend, Monsieur Le Roy, of the
Royal Academy of Sciences, took up my cause and refuted him: my book was
translated into the Italian, German, and Latin languages; and the
doctrine it contained was, by degrees, generally adopted by the
philosophers of Europe, in preference to that of the abbe; so that he
lived to see himself the last of his sect, except Monsieur B----, of
Paris, his _eleve_ and immediate disciple.

What gave my book the more sudden and general celebrity, was the success
of one of its proposed experiments, made by Messieurs Dalibard and
Delor, at Marly, for drawing lightning from the clouds. This engaged the
public attention everywhere. Monsieur Delor, who had an apparatus for
experimental philosophy, and lectured in that branch of science,
undertook to repeat what he called the _Philadelphia experiments_; and
after they were performed before the king and court, all the curious of
Paris flocked to see them. I will not swell this narrative with an
account of that capital experiment, nor of the infinite pleasure I
received in the success of

The phenomenon of retiring and advancing, I think may be accounted for, by supposing the progressive motion to exceed or not equal the consumption of the vapour by condensation.

The air, being eight hundred times rarer than water, is unable to support it but in the shape of vapour, a state in which its particles are separated.

The original movement of the parts towards their common centre would naturally form a whirl there; which would continue upon the turning of the new-formed globe upon its axis, and the greatest diameter of the shell would be in its equator.

Take any clear glass bottle (a Florence flask stript of the straw is best) place it before the fire, and as the air within is warmed and rarefied, part of it will be driven out of the bottle; turn it up, place its mouth in a vessel of water, and remove it from the fire; then, as the air within cools and contracts, you will see the water rise in the neck of the bottle, supplying the place of just so much air as was driven out.

This seems to have been contrived on a supposition, that the entry of the wind would thereby be obstructed, and perhaps it might have been imagined, that the whole force of the rising warm air being condensed, as it were, in the narrow opening, would thereby be strengthened, so as to overcome the resistance of the wind.

One of the effects of their conquest furnishes us with a strong proof, how prevalent manners are even beyond quantity of subsistence; for, when the custom of bestowing on the citizens of Rome corn enough to support themselves and families was become established, and Egypt and Sicily produced the grain, that fed the inhabitants of Italy, this became less populous every day, and the _jus trium liberorum_ was but an expedient, that could not balance the want of industry and frugality.
