nciple to the earth with its electro-magnetic
Aether currents circulating round it, and ask what is the effect of the
rotation first upon the earth, and then upon the rotating Aether
currents?

It is a matter of common knowledge that the effect of rotation upon the
earth when it was in a fluid state was to make its equatorial parts
bulge out as it rotated, with the result that as it solidified the
equatorial diameter exceeded the polar diameter by 26 miles.

If, therefore, the result of rotation upon the earth when in its fluid
state was to make it spread out greater in the equatorial regions than
in any other part of its surface, what must be the effect of a similar
rotation upon the rotatory Aether currents? It can easily be seen that
the rotation of these currents will be to make them spread out into
space in a region which corresponds to the equatorial regions of the
earth, so that the rotating Aether currents will be congregated more in
the equatorial regions of the earth than in any other part of the
earth's surface. The further also they extend into space the less depth
they will have, gradually tapering off, as shown in the illustration,
where _E_ represents the earth and _B_ _C_ the Aether currents (Fig. 29).

Any body, therefore, situated within the sphere of their influence would
be carried round the earth by the currents, and the currents would be to
them their governing and controlling level.

So that the moon, which is held bound to the earth by the two opposite
and equal forces, would always be carried around the earth by those
electro-magnetic Aether currents, and outside of those currents it could
not pass. But the earth is only 8000 miles in diameter, therefore if the
currents gradually tapered off as suggested, by the time the aetherial
currents reached the distance of the moon, their depth would not exceed
2000 or 3000 miles.

The diameter of the moon is, however, only 2160 miles, so that the
rotating Aether currents would practically form an ocean in which the
moon would swim, and one constant level on which it revolves in space.
Wherever the earth was carried by the aetherial currents of the sun,
there the aetherial currents of the earth would carry the moon, its mean
distance by the conjoint working of the two co-equal forces having been
permanently fixed.

So that it can be readily seen, as regards the moon, that the earth's
aetherial currents form the plane on w
