Experiments and Observations on Electricity Made at Philadelphia in America

impossibility of success, in the experiments propos'd,
to draw out the effluvial virtues of a non-electric, as cinnamon for
instance, and mixing them with the electrical fluid, to convey them with
that into the body, by including it in the globe, and then applying
friction, etc. For though the effluvia of cinnamon, and the electrical
fluid should mix within the globe, they would never come out together
through the pores of the glass, and so go to the prime conductor; for the
electrical fluid itself cannot come through; and the prime conductor is
always supply'd from the cushion, and that from the floor. And besides,
when the globe is filled with cinnamon, or other non-electric, no
electrical fluid can be obtain'd from its outer surface, for the reason
before-mentioned. I have try'd another way, which I thought more likely to
obtain a mixture of the electrical and other effluvia together, if such a
mixture had been possible. I placed a glass plate under my cushion, to cut
off the communication between the cushion and floor; then brought a small
chain from the cushion into a glass of oil of turpentine, and carried
another chain from the oil of turpentine to the floor, taking care that the
chain from the cushion to the glass touch'd no part of the frame of the
machine. Another chain was fix'd to the prime conductor, and held in the
hand of a person to be electrised. The ends of the two chains in the glass
were near an inch distant from each other, the oil of turpentine between.
Now the globe being turn'd, could draw no fire from the floor through the
machine, the communication that way being cut off by the thick glass plate
under the cushion: it must then draw it through the chains whose ends were
dipt in the oil of turpentine. 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. I likewise put
into a phial, instead of water,

It seems natural to conclude from this, that water and air were ingredients in their original composition; for men cannot make new matter of any kind.

I know not how this phenomena is to be accounted for, but it gives me occasion to mention some loose notions relating to heat and cold, which I have for some time entertained, but not yet reduced into any form.

Why damp clothes should then occasion colds, is a curious question, the discussion of which I reserve for a future letter or some future conversation.
