axis of the globe, and frame of the machine, the new collected
electrical fluid can enter and remain in the outer surface, and none
of it (or a very little) will be received by the prime conductor. As
this charged part of the globe comes round to the cushion again,
the outer surface delivers its overplus fire into the cushion, the
opposite inner surface receiving at the same time an equal quantity
from the floor. Every electrician knows that a globe wet within
will afford little or no fire, but the reason has not before been
attempted to be given, that I know of.

34. So if a tube lined with a non-electric be rubbed[54], little or
no fire is obtained from it; what is collected from the hand, in the
downward rubbing stroke, entering the pores of the glass, and driving
an equal quantity out of the inner surface into the non-electric
lining: and the hand in passing up to take a second stroke, takes out
again what had been thrown into the outer surface, and then the inner
surface receives back again what it had given to the non-electric
lining. Thus the particles of electrical fluid belonging to the
inside surface go in and out of their pores every stroke given to the
tube. Put a wire into the tube, the inward end in contact with the
non-electric lining, so it will represent the Leyden bottle. Let a
second person touch the wire while you rub, and the fire driven out
of the inward surface when you give the stroke, will pass through him
into the common mass, and return through him when the inner surface
resumes its quantity, and therefore this new kind of Leyden bottle
cannot be so charged. But thus it may: after every stroke, before
you pass your hand up to make another, let a second person apply his
finger to the wire, take the spark, and then withdraw his finger;
and so on till he has drawn a number of sparks; thus will the inner
surface be exhausted, and the outer surface charged; then wrap a
sheet of gilt paper close round the outer surface, and grasping it
in your hand you may receive a shock by applying the finger of the
other hand to the wire: for now the vacant pores in the inner surface
resume their quantity, and the overcharged pores in the outer surface
discharge that overplus; the equilibrium being restored through your
body, which could not be restored through the glass[55]. If the tube
be exhausted of air, a non-electric lining, in contact with

Care was taken before the Hour to replace what Portion had been lost, of the inflammable Air, or of its Force, by injecting more.

I am told it is constructed of Linen & Paper, and is to be filled with a different Air, not yet made Public, but cheaper than that produc'd by the Oil of Vitriol, of which 200 Paris Pints were consum'd in filling the other.

Some think Progressive Motion on the Earth may be advanc'd by it, and that a Running Footman or a Horse slung and suspended under such a Globe so as to have no more of Weight pressing the Earth with their Feet, than Perhaps 8 or 10 Pounds, might with a fair Wind run in a straight Line across Countries.

Most is expected from the new one undertaken upon subscription by Messieurs Charles and Robert, who are Men of Science and mechanic Dexterity.

Probably while they were employed in keeping up the Fire, the Machine might turn, and by that means they were _desorientes_ as the French call it.

Your Philosophy seems to be too bashful.
