ricity constantly flowing
round the heavenly bodies, which produce and give rise to the permanent
magnetism of those bodies.

If we desired still further confirmation as to the circulating motions of
the Aether caused by a rotating body, we find it in the writings of
Herschel, who in relation to this matter asks:[39] "What is the law of
density of the resisting medium which surrounds the sun? Is it at rest or
in motion? If the latter, in what direction does it move? Circularly round
the sun, or traversing space? If circularly, in what plane? Supposing the
neighbourhood of the sun to be filled with material fluid, it is not
conceivable that the circulation of the planets in it for ages should not
have impressed upon it some degree of rotation in their own direction, and
this may preserve them from the extreme effects of accumulated
resistance!" Words like these from one of the most searching intellects of
the last century are well worthy of our consideration, and the suggested
effect on the Aether caused by the continued rotation of the earth gives
us the key not only to the problem of celestial magnetism, but also to the
other outstanding scientific problems.

For example, there is the problem of the relation of moving matter to
the Aether around it which still remains unsolved. The physical cause of
the rotation of the earth, and all other celestial bodies upon their
axes, with unceasing regularity, still remains to be discovered. The
physical explanation as to the reason why the earth moves round the sun
in its orbit according to Kepler's Laws, has yet to be determined, and,
lastly, there is the relation of the magnetic vibration to the electric
vibration in connection with the electro-magnetic theory of light still
to be solved.

Now, presuming that all these can be solved by the philosophical
hypothesis, that the electro-magnetic Aether circulates round each
planet and sun and star, that revolves in space, then we are justified
in our conclusion that such is the true cause of all electro-magnetism
that exists in connection with planetary and stellar bodies. I venture
to premise that all these problems can be solved by the simple solution
here given, and will prove that this solution adequately accounts for
all the other phenomena referred to.

Before proceeding to do this, we will endeavour to prove this hypothesis
by an altogether different method of reasoning, in order to confirm the
statements made in this ar
