ctly what happens, as Mercury has an orbital velocity of 29 miles per
second, while Venus has an orbital velocity of 22 miles per second.

As the angular velocity decreases in proportion as the distance
increases, it follows that at the respective mean distances not only of
Venus, but also of Mars, Jupiter, Saturn, Uranus and Neptune, the
capacity of the Aether to exert its impressed force upon the various
planets will decrease as the distance increases, with the result that
the farther a planet is from the sun, the less force will the Aether
currents exert upon that planet, with the result that its orbital
velocity should decrease as the distance increases, and this is
perfectly in accordance with planetary phenomena.

Here, then, we have at once a physical basis for Newton's Second Law of
Motion, the results of which are entirely in harmony with observation
and experiment, and whose conception fully satisfies all the Rules of
Philosophy; as it is simple in conception, fully agrees with observation
and experiment, and satisfactorily explains the Second Law of Motion
sought to be explained.

Thus we find that from the physical standpoint, as well as from the
mathematical standpoint, "Change of motion is proportional to the
impressed force, and takes place in the direction in which the force is
impressed," that is, in a circular direction.

We have therefore arrived at exactly the same result that Newton arrived
at, except that he had to introduce a third factor, viz. the
Parallelogram of Forces, while we have produced the result by a simpler
method, which, according to his own rules, is more philosophical, as all
effects are produced by the simplest causes, as Newton himself stated in
Rule 1. Thus it is the rotatory electro-magnetic Aether currents that
urge the planets round the sun; and, as will be shown later, it is the
same Aether currents in combination with the other motions that give
rise to the physical cause of Kepler's Laws. It is the electro-magnetic
Aether currents that produce the regular decrease in the velocity of the
planets in their orbits, because of the regular decrease of the mass and
velocity of the Aether currents themselves.

We have now a physical cause as well as a mathematical explanation of
the decrease of the velocity of a planet in its orbit, which physical
cause is in perfect harmony with all philosophical rules. The following
table shows the gradual decrease in the velocity of each pla
