this. If the sun gives rise to the aetherial light waves,
and these light waves are identical with electro-magnetic waves as
proved by Hertz, then the sun must either be an electrified body or else
a magnet.

It must be one or the other, because, if it were not, we should then
have an anomaly in Nature of a body emitting electro-magnetic waves
which is itself neither electrified nor a magnet. Therefore, according
to our second Rule of Philosophy, such a body would be incapable of
giving rise to these waves, as such a result would be contrary to
universal experience and experiment.

We know that the earth is a magnet, but up to the present it has never
been proved that the sun is a magnet, although, as I shall show later
on, Lord Kelvin and others have suggested such a possibility. If we
assume that the sun is a magnet, our grounds for assumption would not be
so strong at this point, and our reasons so philosophical, as they are
if we assume that the sun is an electrified body.

We have philosophical reasoning to prove that the sun is an electrified
body in the fact that it emits or gives rise to electro-magnetic waves
in the Aether, and no other hypothesis can be made other than that the
sun is an electrified body, in order to prove the connection between the
two.

Thus we affirm that the sun is an electrified body, which like any
other electrified body is capable of generating electric waves, and
speeding them through the Aether with similar velocity to that of light.
Not only so, but, like any other electrified body, it must have its
electric field and possess the ability to electrify any other body by
induction, that may happen to be in its electric field, as we shall see
later on.

Further, being an electrified body, the electric density will be
greatest near the sun's surface, and this fact fully accords with our
statement in Art. 45, that Aether is gravitative. As pointed out in that
Art., if Aether be gravitative, it must be densest nearest to the
attracting body; and, as Aether has an electric basis, then with the
denser Aether there must be an increased electric density, which can
only happen provided the sun is an electrified body.

Sir G. Stokes was also of this opinion, for in his Burnet Lectures on
Light he writes (p. 212): "There is nothing, therefore, unreasonable
in supposing that the sun may be a permanently charged body."

So that all the reasoning that has led to this result seems to harmoniz
