kind to that of the surface.

1566. This effect is one of induction between the bodies, not of
communication. The ball, when related to the positive charged surface by
the intervening dielectric, has its opposite sides brought into contrary
states, that side towards the boiler being negative and the outer side
positive. More inductric action is directed towards it than would have
passed across the same place if the ball had not been there, for several
reasons; amongst others, because, being a conductor, the resistance of the
particles of the dielectric, which otherwise would have been there, is
removed (1298.); and also, because the reacting positive surface of the
ball being projected further out from the boiler than when there is no
introduction of conducting matter, is more free therefore to act through
the rest of the dielectric towards surrounding conductors, and so favours
the exaltation of that inductric polarity which is directed in its course.
It is, as to the exaltation of force upon its outer surface beyond that
upon the inductric surface of the boiler, as if the latter were itself
protuberant in that direction. Thus it acquires a state like, but higher
than, that of the surface of the boiler which causes it; and sufficiently
exalted to discharge at its positive surface to the air, or to affect small
particles, as it is itself affected by the boiler, and they flying to it,
take a charge and pass off; and so the ball, as a whole, is brought into
the contrary inducteous state. The consequence is, that, if free to move,
its tendency, under the influence of all the forces, to approach the boiler
is increased, whilst it at the same time becomes more and more exalted in
its condition, both of polarity and charge, until, at a certain distance,
discharge takes place, it acquires the same state as the boiler, is
repelled, and passing to that conductor most favourably circumstanced to
discharge it, there resumes its first indifferent condition.

1567. It seems to me, that the manner in which inductric bodies affect
uncharged floating or moveable conductors near them, is very frequently of
this nature, and generally so when it ends in a carrying operation (1562.
1602.). The manner in which, whilst the dominant inductric body cannot give
off its electricity to the air, the inducteous body _can_ effect the
discharge of the same kind of force, is curious, and, in the case of
elongated or irregularly shaped conductors, such
