An Essay to Shew the Cause of Electricity; and Why Some Things are Non-Electricable.: In Which Is Also Consider'd Its Influence in the Blasts on Human Bodies, in the Blights on Trees, in the Damps in Mines; And as It May Affect the Sensitive Plant, &c.

Electricity -- Early works to 1850; Martin, Benjamin, 1705-1782. Essay on electricity
It is no Wonder, therefore, that all undisorder’d Nature should be
equally electrify’d: For how is it possible to have it otherwise? since,
if a Person stands on the Ground, and touches but the _Capsula_ before
he touches the Body, the electric Fire starts through him into the
Ground, as swift as Lightning, and thence into the universal lambent
Flame, from whence it was taken.
Lightning from hence may in some measure be accounted for; though I
cannot so exactly tell what collects it together, as I can in this
factitious Lightning here treated of, yet I can suppose, that the Cause
of Lightning is produc’d from a great Quantity of this Fire before
spoken of; which being driven together, and included in a limited State,
or Covering of some Kind, when discharged from this Covering, it goes
off in an Explosion, which is Thunder. The Lightning I need not
describe, being intirely the same with Electricity; for it will kill
without a Wound, and pass through every thing, as this seems to do.
I am to shew, first, the Cause of its kindling a Flame in certain
compounded Liquors; which, if what I have supposed be true, that it is
by the means spoken of that this Fire is collected and driven on, as I
have said, it is plain to be seen, that at the Finger’s End of a Person
electrify’d, or at the End of a Sword, held as before described, being
in a dark Room, a Flame issues from them: It is no Wonder then, that an
inflammable Spirit, as is shewn, should take Fire from it.
The second Thing I proposed to shew is, Why a Tube of Glass, rubb’d
smartly in the Hand, so as to become electrical, repels Leaf-Gold,
Feathers, and other small Bodies; and when they touch any less
electrify’d Body, they shall return back again to the Tube, and so _vice
versa_. Now, if what I have been saying be true, how can this
_Phænomenon_ be otherwise? For, if that Piece of Leaf-Gold, _&c._ be
electrify’d by the Touch of the Tube, then it has as full Power given to
it as the electrify’d Body had to give to it: And when the Gold, _&c._
touches any other Body, it imparts to it so much of its electrical
Property as it had in itself: And then it may be consider’d in the same
State it was in when first electrify’d: And so it will be repeatedly
attracted to it, and be repell’d _toties quoties_.
