itself (1337.). If the globe were charged, these little conductors would
all be polar; if the globe were discharged, they would all return to their
normal state, to be polarized again upon the recharging of the globe. The
state developed by induction through such particles on a mass of conducting
mutter at a distance would be of the contrary kind, and exactly equal in
amount to the force in the inductric globe. There would be a lateral
diffusion of force (1224. 1297.), because each polarized sphere would be in
an active or tense relation to all those contiguous to it, just as one
magnet can affect two or more magnetic needles near it, and these again a
still greater number beyond them. Hence would result the production of
curved lines of inductive force if the inducteous body in such a mixed
dielectric were an uninsulated metallic ball (1219. &c.) or other properly
shaped mass. Such curved lines are the consequences of the two electric
forces arranged as I have assumed them to be: and, that the inductive force
can be directed in such curved lines is the strongest proof of the presence
of the two powers and the polar condition of the dielectric particles.

1680. I think it is evident, that in the case stated, action at a distance
can only result through an action of the contiguous conducting particles.
There is no reason why the inductive body should polarize or affect
_distant_ conductors and leave those _near_ it, namely the particles of the
dielectric, unaffected: and everything in the form of fact and experiment
with conducting masses or particles of a sensible size contradicts such a
supposition.

1681. A striking character of the electric power is that it is limited and
exclusive, and that the two forces being always present are exactly equal
in amount. The forces are related in one of two ways, either as in the
natural normal condition of an uncharged insulated conductor; or as in the
charged state, the latter being a case of induction.

1682. Cases of induction are easily arranged so that the two forces being
limited in their direction shall present no phenomena or indications
external to the apparatus employed, Thus, if a Leyden jar, having its
external coating a little higher than the internal, be charged and then its
charging ball and rod removed, such jar will present no electrical
appearances so long as its outside is uninsulated. The two forces which may
be said to be in the coatings, or in the particles o
