nto another; for
not the slightest change is in such circumstances impressed upon the
character or action of the force.

1685. Having given this general theoretical view, I will now notice
particular points relating to the nature of the assumed electric polarity
of the insulating dielectric particles.
1686. The polar state may be considered in common induction as a forced
state, the particles tending to return to their normal condition. It may
probably be raised to a very high degree by approximation of the inductric
and inducteous bodies or by other circumstances; and the phenomena of
electrolyzation (861. 1652. 1796.) seem to imply that the quantity of power
which can thus be accumulated on a single particle is enormous. Hereafter
we may be able to compare corpuscular forces, as those of gravity,
cohesion, electricity, and chemical affinity, and in some way or other from
their effects deduce their relative equivalents; at present we are not able
to do so, but there seems no reason to doubt that their electrical, which
are at the same time their chemical forces (891. 918.), will be by far the
most energetic.
1687. I do not consider the powers when developed by the polarization as
limited to two distinct points or spots on the surface of each particle to
be considered as the poles of an axis, but as resident on large portions of
that surface, as they are upon the surface of a conductor of sensible size
when it is thrown into a polar state. But it is very probable,
notwithstanding, that the particles of different bodies may present
specific differences in this respect, the powers not being equally diffused
though equal in quantity; other circumstances also, as form and quality,
giving to each a peculiar polar relation. It is perhaps to the existence of
some such differences as these that we may attribute the specific actions
of the different dielectrics in relation to discharge(1394. 1508.). Thus
with respect to oxygen and nitrogen singular contrasts were presented when
spark and brush discharge were made to take place in these gases, as may be
seen by reference to the Table in paragraph 1518 of the Thirteenth Series;
for with nitrogen, when the small, negative or the large positive ball was
rendered inductric, the effects corresponded with those which in oxygen
were produced when the small positive or the large negative ball was
rendered inductric.
