81. L'air est un corps originairement électrique, & lorsqu'il est sec,
il n'est point conducteur du feu électrique, il ne le reçoit point des
autres corps, & ne leur donne point; autrement aucun corps environné
d'air ne pourroit être électrisé positivement & négativement; car si on
essayoit de l'électriser positivement, l'air emporteroit aussitôt le
surplus, ou si c'étoit négativement, l'air suppléeroit à ce qui
manqueroit.

82. L'eau étant électrisée, les vapeurs qui s'en exhalent seront
également électrisées, & flottant dans l'air sous la forme de nuages ou
autrement, elles retiendront cette quantité de feu électrique jusqu'à ce
qu'elles rencontrent d'autres nuages ou d'autres corps qui ne soient pas
électrisés au même point, & alors elles le communiqueront, comme il a
été dit ci-devant.

83. Chaque particule de matière électrisée est repoussée par chaque
autre particule également électrisée; ainsi le courant d'une fontaine
également serré & continu, dès qu'il sera électrisé, se séparera &
s'étendra sous la forme d'une vergette, chaque goute faisant effort pour
s'éloigner de chaque autre goute; mais lorsque le feu électrique leur
est enlevé, elles se raprochent & se rejoignent.

84. L'eau qui est fortement électrisée (aussi bien que celle qui est
échauffée par le feu commun,) s'éleve en vapeurs plus abondamment,
l'attraction de cohésion entre ses particules étant considérablement
affoiblie par la puissance opposée de répulsion introduite avec le feu
électrique; & lorsque quelque particule est dégagée par quelque moyen
que ce soit, elle est immédiatement repoussée, & s'envole ainsi dans
l'air.

85. S'il arrive que les particules soient situées comme A & B, elle sont
plus aisément dégagées que C & D, parce que chacune est en contact avec
trois seulement, au lieu que C & D sont chacune en contact avec neuf.
Lorsque la surface de l'eau éprouve la moindre agitation, les particules
sont continuellement poussées dans l'état représenté par la figure VIII.

86. Le frottement entre un corps non-électrique & un corps
originairement électrique produit le feu électrique, non en le _créant_,
mais en le _rassemblant_: car il est également répandu dans nos murs,
dans nos chambres, dans la terre & dans toute la masse de la matière
commune; ainsi le globe de verre tournant, tandis qu'il frotte contre le
coussin, tire le feu du coussin, lequel en est dédommagé par le cadre de
la machine, & ce cadre par le plancher sur lequel il est posé. Coupez la
communication par le moyen d'un verre épais ou d'un gâteau de cire placé
sous le coussin, le feu ne peut plus être produit, parce qu'il ne peut
plus être rassemblé.

87. L'Océan est un composé d'eau, corps non-électrique, & de sel, corps
originairement électrique.

88. Lorsqu'il

The notes one of my uncles (who had the same kind of curiosity in collecting family anecdotes) once put into my hands furnished me with several particulars relating to our ancestors.

After a while I went through one course only in a year, and afterward only one in several years, till at length I omitted them entirely, being employed in voyages and business abroad, with a multiplicity of affairs that interfered; but I always carried my little book with me.

During the contest an unlucky occurrence hurt his cause exceedingly.

Partnerships often finish in quarrels; but I was happy in this, that mine were all carried on and ended amicably, owing, I think, a good deal to the precaution of having very explicitly settled, in our articles, everything to be done by or expected from each partner, so that there was nothing to dispute, which precaution I would therefore recommend to all who enter into partnership; for, whatever esteem partners may have for and confidence in each other at the time of the contract, little jealousies and disgusts may arise, with ideas of inequality in the care and burden of the business, etc.

Like a man traveling in foggy weather; those at some distance before him on the road he sees wrapped up in the fog as well as those behind him, and also the people in the fields on each side, but near him all appears clear, though in truth he is as much in the fog as any of them.

is said, mechanically; for he did not see a light just before us, which had been hid by the studding sails[205] from the man at the helm, and from the rest of the watch, but by an accidental yaw of the ship was discovered and occasioned a great alarm, we being very near it, the light appearing to me as big as a cart wheel.

"Some time since there fell into my hands, to my great joy, about twenty-three sheets in thy own handwriting, containing an account of the parentage and life of thyself, directed to thy son, ending in the year 1730; with which there were notes, likewise in thy writing; a copy of which I inclose, in hopes it may be a means, if thou continued it up to a later period, that the first and latter part may be put together; and if it is not yet continued, I hope thee will not delay it.

" They joined in desiring him to speak his mind, and gathering round him, he proceeded as follows: "Friends," said he, "the taxes are indeed very heavy, and if those laid on by the government were the only ones we had to pay, we might more easily discharge them; but we have many others, and much more grievous to some of us.
