pace, rotating with it in
the same way that the atmosphere does, as we shall prove later on.

This conception is fully in accord with our hypothesis as to the
physical explanation of the cause of the electro-magnetic character of
all the heavenly bodies, and indeed is the only physical solution that
can adequately account for all the varied phenomena hitherto unexplained
in connection with the celestial mechanism.

From the foregoing statements, we are now in a position to consider the
term Electro-Kinetic Energy, as used by Clerk Maxwell. What does he mean
by Electro-Kinetic Energy? Let us see what he has to say about the term
himself.

In par. 636 of his _Magnetism and Electricity_ he writes: "According to
our hypothesis we assume kinetic energy to exist wherever there is
magnetic force, that is, in general, in every part of the field. This
energy exists, therefore, in some kind of motion of the matter in every
portion of space;" while again, in par. 569, he states: "The electric
current cannot be conceived except as a kinetic phenomenon." Even
Faraday speaks of the electric current as "something progressive, and
not a mere arrangement" (_Exp. Res._ 283).

Then again in par. 552 he writes: "It appears, therefore, that a system
containing an electric current is a seat of energy of some kind, and,
since we can form no conception of an electric current except as a
kinetic phenomenon, its energy must be kinetic energy, that is to say,
the energy which a moving body has in virtue of its motion."

Here, therefore, according to Clerk Maxwell, the kinetic energy of an
electro-magnetic field is nothing more or less than the energy which a
moving body possesses in virtue of its motion. Any other explanation of
kinetic energy would be opposed to all the Rules of Philosophy; for
experience in its widest form incontrovertibly proves that all kinetic
energy is associated, and alone associated, with a moving body;
therefore in all electro-magnetic fields there is this kinetic energy
ever being manifested. We have, however, learned that the solar system
forms a huge electro-magnetic field, traversed by lines of force, as
Maxwell and Faraday suggested. Therefore, in the solar system, there
must be this kinetic energy due to the motion of a moving body, which is
the electro-magnetic Aether.

We have, however, just arrived at the conclusion that in the solar
system there is ever going on a circulatory or rotatory movement of the
