er hour, accomplishing
its entire journey in the short period of 88 days. Venus, whose mean
distance is about 67,000,000 miles, is carried round the sun at the
reduced rate of 78,000 miles per hour, completing her orbit in the
increased time of 224 days. Our own Earth, at the still further
increased mean distance of 92,000,000 miles, performs her journey at the
reduced velocity of 64,000 miles per hour, accomplishing the journey
round the sun in a period of 365 days.

Thus, the further we get from the sun, the slower becomes the movement
of a planet in its orbit, and the longer it takes to complete its
revolution round its controlling centre. Mars, at the increased distance
of 141,000,000 miles, possesses a reduced velocity of 54,000 miles per
hour, and completes its orbit in the increased duration of 686 days. So
the decrease of velocity goes on, as the planets increase their mean
distance from the sun, as the following figures show--

MEAN DISTANCE. PERIOD OF ORBITAL VELOCITY
REVOLUTION. PER HOUR.

Jupiter 482 millions 4,332 days 28,000 miles
Saturn 884 " 10,759 " 21,600 "
Uranus 1,780 " 30,687 " 1,800 "
Neptune 2,780 " 60.127 " 900 "

The relation of this decrease of velocity to the mean distance is
exactly determined by Kepler's Third Law, in which he states that the
square of the periodic time is proportionate to the cube of the mean
distance. That this is true has already been proved in Art. 28.

In conclusion on this point, let me ask the reader to try to conceive
any other physical explanation for this decrease of orbital velocity as
the mean distance is increased, than the one given here, namely, the
decrease in the velocity and mass of the radiating and circulating
Aether currents, and if such attempt is made, I premise that its only
result will be utter failure. No other physical conception to account on
a physical basis for all Kepler's Laws can be given or conceived, than
that which finds its origin in the universal electro-magnetic Aether,
which by its pressures, tensions and motions gives rise to all the
phenomena incidental to, and associated with, planetary and stellar
phenomena.

Therefore, inasmuch as all the laws of motion, and all Kepler's Laws can
be accounted for by a gravitating and rotatory Aether medium, those
facts alone, apart fro
