Expériences et observations sur l'électricité faites à Philadelphie en Amérique

de cuivre, dont le fléau ait au moins 2. pieds de longueur, de
manière que les bassins attachés à des cordons de soye soient environ à
un pied de terre, ces bassins tourneront circulairement par le
détortillement de la ficelle. Si l'on plante sur le plancher un poinçon
de métal, dont la tête soit arrondie & polie, de façon que les bassins
puissent passer pardessus en décrivant leur cercle; si dans cet état on
électrise un des bassins en lui appliquant le fil-d'archal de la
bouteille électrique, on verra ce bassin s'abaisser en passant sur le
poinçon, & même décharger son feu sur cet instrument, s'il est à une
distance convenable.

Si après cela on attache une aiguille la pointe en haut sur le plancher
auprès du poinçon, la tête de cet instrument, loin d'attirer comme
auparavant le bassin électrisé, semblera le repousser, parce que la
pointe de l'aiguille, quoique beaucoup plus basse, aura tiré le feu
électrique dont le bassin étoit chargé, avant qu'il soit venu à portée
d'être attiré par la tête du poinçon.

Ces deux bassins peuvent nous représenter deux nuages, l'un un nuage de
mer, & l'autre un nuage de terre; leur mouvement horizontal sur le
plancher sera dans la même hypothèse, celui des nuages au-dessus de la
terre, & le poinçon élevé représentera une montagne, une éminence ou un
grand édifice; on comprendra alors comment les nuages électrisés, en
passant au-dessus des montagnes ou des bâtimens à une trop grande
hauteur pour les frapper, en peuvent être attirés jusqu'à la distance
qui leur est nécessaire pour cet effet.

Comme d'ailleurs l'aiguille fixée la pointe en haut sur le plancher au
dessous du poinçon tire en silence le feu électrique du bassin à une
distance beaucoup plus grande que la distance requise pour frapper, &
prévient ainsi la descente vers le poinçon: comme le bassin électrisé,
quand même il viendroit par son propre mouvement assez près pour
frapper, ne pourroit le faire, parce qu'il auroit alors été dépoüillé de
la plus grande partie de son feu: comme enfin dans ces deux cas le
poinçon seroit toujours garanti du choc, il est plus que probable que la
connoissance du pouvoir des pointes peut être d'un très-grand avantage à
l'humanité pour préserver des atteintes de la foudre des maisons, les
églises, les vaisseaux, &c.

Il ne s'agiroit, pour y parvenir, que de fixer perpendiculairement sur
les parties les plus élevées de ces édifices des verges de fer faites en
forme d'aiguilles, & dorées pour prévenir la rouille, & d'abaisser du
pied de ces verges, un fil-d'archal au dehors des bâtimens, jusqu'à ce
qu'il touchât la terre ou

Text Comparison with The Autobiography of Benjamin Franklin

Page 2
Having emerged from the poverty and obscurity in which I was born and bred, to a state of affluence and some degree of reputation in the world, and having gone so far through life with a considerable share of felicity, the conducing means I made use of, which with the blessing of God so well succeeded, my posterity may like to know, as they may find some of them suitable to their own situations, and therefore fit to be imitated.

By the same wife he had four children more born there, and by a second wife ten more, in all seventeen; of which I remember thirteen sitting at one time at his table, who all grew up to be men and women, and married; I was the youngest son, and the youngest child but two, and was born in Boston, New England.

By this means he turned our attention to what was good, just, and prudent in the conduct of life; and little or no notice was ever taken of what related to the victuals on the table, whether it was well or ill dressed, in or out of season, of good or bad flavor, preferable or inferior to this or that other thing of the kind, so that I was bro't up in such a perfect inattention to those matters as to be quite indifferent what kind of food was set before me, and so unobservant of it, that to this day if I am asked I can scarce tell a few hours after dinner what I dined upon.

With this view I took some of the papers, and, making short hints of the sentiment in each sentence, laid them by a few days, and then, without looking at the book, try'd to compleat the papers again, by expressing each hinted sentiment at length, and as fully as it had been expressed before, in any suitable words that should come to hand.

" He ask'd me a few questions, put a composing stick in my hand to see how I work'd, and then said he would employ me soon, though he had just then nothing for me to do; and, taking old Bradford, whom he had never seen before, to be one of the town's people that had a good will for him, enter'd into a conversation on his present undertaking and projects; while Bradford, not discovering that he was the other printer's father, on Keimer's saying he expected soon to get the greatest part of the business into his own hands, drew him on by artful questions, and starting little doubts, to explain all his views, what interests he reli'd on, and in what manner he intended to proceed.

The modest way in which I propos'd my opinions procur'd them a readier reception and less contradiction; I had less mortification when I was found to be in the wrong, and I more easily prevail'd with others to give up their mistakes and join with me when I happened to be in the right.

The fund for paying them was the interest of all the paper currency then extant in the province upon loan, together with the revenue arising from the excise, which being known to be more than sufficient, they obtain'd instant credit, and were not.
