force is lessened
gradually, then the repulsive force is lessened gradually; and if
quickly, by the quicker motion of the planet through space, then the
repulsive motion is also increased with a quicker motion.

Further, like the repulsive power of light and heat, the repulsive power
of electricity takes exactly the same path as the attractive power of
Gravitation.

Thus we learn that the sun is the centre of two forces: first, a
centrifugal force due to the pressure of the aetherial medium which is
ever directed away from the sun, and which may either be produced by
electric or thermal or light waves; and second, it is the centre of a
centripetal force known as the Law of Gravity, whatever that may be due
to. Further, the centrifugal force is also subject to the same law of
intensity as the centripetal force, and moreover takes exactly the same
path which the centripetal force takes.

So that we have only to prove that they both agree in another
particular, viz. that their power is regulated by the product of their
masses, and then we shall have discovered a real physical force, which
is the exact complement and counterpart of the centripetal force due to
gravity.

ART. 85. _Second Law of Electricity. (Product of Masses.)_--We have now
to prove that the centrifugal force exerted by any electrified body
operates upon another electrified body in the same proportion and with
exactly the same force which governs the centripetal force. From Art. 21
we learn that the centripetal force which is exerted by one body upon
another is equal to the product of their masses. In order, therefore,
for any centrifugal force to be the exact counterpart of that force, it
too must be subject to the same law of proportion, that is, the
repulsive force between any two bodies must be equal to the product of
their masses.

We have shown that there is a repulsive force exerted by the Aether from
the phenomena of heat, light, and electricity, and that that repulsive
force or energy fulfils every condition required by a centrifugal force
or motion, with the exception of the part referring to the fact that
such a force must be proportionate to the product of their masses. What
we were unable to accomplish, however, from the phenomena of heat or
light we are now able to accomplish from the phenomena of electricity.

For in the phenomena of electricity we find a law which runs thus: "The
force of repulsion" (which is the part of electricity
