ging periods and distances, but that each planet can only
be in equilibrio in its own orbit. That any change in the eccentricities
of the planetary orbits will neither increase nor diminish the action of
the radial stream of the vortex, and consequently will not interfere
with the law of gravitation. In relation to the numerous questions that
will spring up from such a position, it is sufficient here to say, that
it is believed all objections can be satisfactorily answered; while, by
this light, a long range of phenomena that have hitherto baffled the
sagacity of the wise, come out plainly, and discover their parentage.
In cometary astronomy we shall find much to substantiate these views.
The anomalies in their motions, the discrepancies in their periods,
calculated from different sets of observations, their nebulosities and
appendages, will all receive a satisfactory solution; and these lawless
wanderers of the deep be placed in a more interesting light.
TEST OF A THEORY.
It has been remarked that the best evidence of the truth of a theory, is
its ability to refer to some general principle, the greatest number of
relevant phenomena, that, like the component masses of the chiselled
arch, they may mutually bind and strengthen each other. This we claim
to be the characteristic of this theory. At the outset it was not
intended to allude to more than was actually necessary to give an
outline of the theory, and to introduce the main question, yet
untouched. We have exhibited the stones of which the arch is composed;
but they may be pasteboard,--for the reader has not handled them. We
will now produce the keystone, and put it in its place. This he shall
handle and weigh. He will find it hard,--a block of granite, cut from
the quarry of observed facts, and far too heavy to be held in its place
by a mere pasteboard structure.
ENUNCIATION OF THE THEORY.
Quitting, therefore, the region of the planets, we will come down to the
surface of our own globe, to seek for some more palpable evidence of the
truth of the following propositions:
1st. That space is filled with an elastic fluid, possessing inertia
without weight.
2d. That the parts of this fluid in the solar system circulate, after
the manner of a vortex, with a direct motion.
3d. That there are also secondary vortices, in which the planets are
placed.
4th. That the earth is also placed in a vortex of the ethereal medium.
5th. That the satellites are
