with light and heat, would stamp the circulating Aether medium as the
physical cause of all the motions and phenomena associated with the
whole of the celestial mechanism.

ART. 105. _Orbital Motions of Satellites and Planets._--According to
Kepler's First Law, the Earth and all the other planets move round the
sun in orbits which are in the shape of an ellipse. Not only, however,
is the first law true of planetary motion, it is equally true of the
motions of all satellites moving round their primary planets. I wish,
however, to point out, and prove in an indisputable manner, that
Kepler's First Law does not sufficiently explain and determine the exact
orbit of any satellite as it revolves around its primary planet, or even
of any planet as it revolves around the sun.

Simply because, if any satellite or planet is to perform a perfect
ellipse as it revolves around its central body, that central body must
only move for a time and must then come to rest, or partly return in its
journey in order for a perfect ellipse to be formed, as shown in a
previous figure. Now we know from observation that such a thing as rest
in space by any planet, or by the sun, is absolutely unknown in the
celestial mechanism.

From Art. 92 we learned that the electro-magnetic Aether currents not
only circulate round the sun, but they also circulate round each planet.
Thus we found there were electro-magnetic Aether currents circulating
round each planet, while those planets themselves were circled round the
sun by the Aether currents generated by the sun; the planetary Aether
currents in their turn propel the satellites round their primary
planets. It can easily be seen, therefore, that such phenomena as rest
and return of a planet in its journey are physical impossibilities, for
either the circulating Aether currents would have to cease circulating,
or would have to return upon themselves in some inconceivable manner.

Thus there is ever going on this conjoint motion, so to speak, of the
sun's aetherial currents which circle all the planets round that body,
and the planetary aetherial currents which circle all the satellites
round their central body, and it is the effect of the conjoint working
of these currents on the planets and satellites to which I wish to call
the reader's attention.

Let us in starting represent the earth's orbit by a perfect ellipse _A_
