because it is equally
attracted by every part. But that is not the case with bodies of any
other figure. From a cube it is more easily drawn at the corners
than at the plane sides, and so from the angles of a body of any
other form, and still most easily from the angle that is most acute.
Thus, if a body shaped as A, B, C, D, E, in Fig. 8. be electrified,
or have an electrical atmosphere communicated to it, and we consider
every side as a base on which the particles rest, and by which they
are attracted, one may see, by imagining a line from A to F, and
another from E to G, that the portion of the atmosphere included
in F, A, E, G, has the line A, E, for its basis. So the portion of
atmosphere included in H, A, B, I, has the line A B for its basis.
And likewise the portion included in K, B, C, L, has B, C, to rest
on; and so on the other side of the figure. Now if you would draw
off this atmosphere with any blunt smooth body, and approach the
middle of the side A, B, you must come very near, before the force
of your attracter exceeds the force or power with which that side
holds its atmosphere. But there is a small portion between I, B, K,
that has less of the surface to rest on, and to be attracted by,
than the neighbouring portions, while at the same time there is a
mutual repulsion between its particles, and the particles of those
portions, therefore here you can get it with more ease, or at a
greater distance. Between F, A, H, there is a larger portion that has
yet a less surface to rest on, and to attract it; here, therefore,
you can get it away still more easily. But easiest of all between
L, C, M, where the quantity is largest, and the surface to attract
and keep it back the least. When you have drawn away one of these
angular portions of the fluid, another succeeds in its place, from
the nature of fluidity, and the mutual repulsion before-mentioned;
and so the atmosphere continues flowing off at such angle, like a
stream, till no more is remaining. The extremities of the portions
of atmosphere over these angular parts, are likewise at a greater
distance from the electrified body, as may be seen by the inspection
of the above figure; the point of the atmosphere of the angle C,
being much

Charmed to a degree of enthusiasm with this mode of disputing, I adopted it, and renouncing blunt contradiction, and direct and positive argument, I assumed the character of an humble questioner.

She was standing at the door, observed me, and thought with reason, that I made a very singular and grotesque appearance.

If you will take upon yourself the debts of the partnership, return my father the hundred pounds he has advanced, pay my little personal debts, and give me thirty pounds and a new saddle, I will renounce the partnership, and consign over the whole stock to you.

Watson's book, of a shock communicated through a great space of dry ground, and suspect there must be some metalline quality in the gravel of that ground; having found that simple dry earth, rammed in a glass tube, open at both ends, and a wire hook inserted in the earth at each end, the earth and wires making part of a circuit, would not conduct the least perceptible shock, and indeed when one wire.

He made first several experiments on fowls, and found, that two large thin glass jars gilt, holding each about six gallons, were sufficient, when fully charged, to kill common hens outright; but the turkeys, though thrown into violent convulsions, and then lying as dead for some minutes, would recover in less than a quarter of an hour.

And the water forced out at one end of the tube is not the very same water that was forced in at the other end at the same time, it was only in motion at the same time.

The barrel, while the lining is laid on, should have the end hoops slack, so that the staves standing at a little distance from each other, may admit the head into its groove.

The flesh of animals, fresh killed in the usual manner, is firm, hard, and not in a very eatable state, because the particles adhere too forcibly to each other.
