Text Comparison with Experiments and Observations on Electricity Made at Philadelphia in America

Page 3
And on the touch of the wire (or of the gun-barrel, which is the same thing) the fire does not proceed from the touching finger to the wire, as is supposed, but from the wire to the finger, and passes through the body to the other hand, and so into the bottom of the bottle.

FRANKLIN, in _Philadelphia_.

A blunt body must be brought within an inch, and draw a spark, to produce the same effect.
Page 9
We think that ingenious gentleman was deceived, when he imagined (in his _Sequel_) that the electrical fire came down the wire from the cieling to the gun-barrel, thence to the sphere, and so electrised the machine and the man turning the wheel,.

Upon the table, over which he hangs, we stick a wire upright as high as the phial and wire, two or three inches from the spider; then we animate him by setting the electrified phial at the same distance on the other side of him; he will immediately fly to the wire of the phial, bend his legs in touching it, then spring off, and fly to the wire in the table; thence again to the wire of the phial, playing with his legs against both in a very entertaining manner, appearing perfectly alive to persons unacquainted.

Thus, the whole force of the bottle, and power of giving a shock, is in the GLASS ITSELF; the non-electrics in contact with the two surfaces, serving only to _give_ and _receive_ to and from the several parts of the glass; that is, to give on one side, and take away from the other.
Page 16
The excuse for mentioning it here, is, that we tried the experiment differently, drew different consequences from it, (for Mr _Watson_ still seems to think the fire _accumulated on the non-electric_ that is in contact with the glass, page 72) and, as far as we hitherto know, have carried it farther.

Thus the stream of a fountain, naturally dense and continual, when electrified, will separate and spread in the form of a brush, every drop endeavouring to recede from every other drop.

more speedily and easily deposite their water, having but little electrical fire to repel and keep the particles separate.

Dip both sets in water, and some cohering to each ball they will represent air loaded.

When the quantity of common fire in the body is small, the quantity of the electrical fire (or the electrical stroke) should be greater: if the quantity of common fire be great, less electrical fire suffices to produce the effect.

(generally) more than it can contain, otherwise all loose portions of it would repel each other, as they constantly do when they have electric atmospheres.

We did not think of its being deprived of sight;.

And as the oil of turpentine being an electric _per se_, would not conduct what came up from the floor, was obliged to jump from the end of one chain, to the end of the other, through the substance of that oil, which we could see in large sparks; and so it had a fair opportunity of seizing some of the finest particles of the oil in its passage, and carrying them off with it: but no such effect followed, nor could I perceive the least difference in the smell of the electrical effluvia thus collected, from what it has when collected otherwise; nor does it otherwise affect the body of a person electrised.

--So when water is thrown on common fire, we do not imagine the element is thereby destroyed or annihilated, but only dispersed, each particle of water carrying off in vapour its portion of the fire, which it had attracted and attached to itself.
