Or fix a needle to the end of a suspended gun-barrel or iron rod so as to point beyond it like a little bayonet, and while it remains there the gun-barrel or rod cannot, by applying the tube to the other end, be electrized so as to give a spark, the fire continually running out silently at the point. In the dark you may see it make the same appearance as it does in the case before mentioned.
To C, standing on the floor, both appear to be electrized; for he, having only the middle quantity of electrical fire, receives a spark upon approaching B, who has an over quantity; but gives one to A, who has an under quantity. If A and B approach to touch each other, the spark is stronger, because the difference between them is greater.
Give him the electrized bottle in his hand. Touch the wire with your finger and then touch his hand or face; there are sparks every time.
The atmosphere is constantly charged with positive electricity, electricity furnished by the vapors that rise from the sea, especially in tropical regions, and, on the other hand, the earth is negatively electrized.
After such touch there is no spark between either of them and C, because the electrical fire in all is reduced to the original equality. If they touch while electrizing, the equality is never destroyed, the fire only circulating. Hence have arisen some new terms among us. Or rather, B is electrized plus; A, minus. And we daily in our experiments electrize bodies plus or minus, as we think proper.
We increase the force of the electrical kiss vastly, thus: Let A and B stand on wax, or A on wax and B on the floor; give one of them the electrized vial in hand; let the other take hold of the wire; there will be a small spark; but when their lips approach they will be struck and shocked.
As an extra precaution with the "rescued," when they were put to work, each of them with a kind of shirt of mail, worn over his coat, which could easily be electrized by a metallic filament connecting with the communal dynamo, and under these conditions they each did a full day's work during the Obligatories.
Watson's ingenious Sequel came to hand; and these were some of the new things I intended to have communicated to you. But now I need only mention some particulars not hinted in that piece, with our reasonings thereupon; though perhaps the latter might well enough be spared. But if the persons on wax touch one another during the exciting of the tube, neither of them will appear to be electrized.
Watson has shown; you may also accumulate it or subtract it, upon or from any body, as you connect that body with the rubber or with the receiver, the communication with the common stock being cut off. We suppose it was driven off, and not brought on through that wire; and that the machine and man, etc., were electrized minus that is, had less electrical fire in them than things in common.
