By some such means only is it conceivable how solar matter can arrive at Neptune, the Earth, or even Mercury,--the _inert_ sun being incapable of radiating anything from itself, and solar atoms requiring a physical impelling cause, in motion, and acting on the rear of each from the sun to the extreme of planetary space. A circulating medium of constantly-increasing radius, appears indispensably necessary for the purpose of conveying solar matter through the regions of space, and for the maintaining all planetary motion in the same uniform direction. The subject is open to all, and worthy of notice: what is now advanced will be passed over, from having no mathematical appendage, but which, makes even false causes pass for the demonstrated truth. The mathematical science has not to this day demonstrated the cause of planetary motion,--a subject wholly indifferent to modern astronomy, in which the false, self-gravitation, in connection with _inertia_, satisfies all as long as the astronomer remains self-satisfied. _Formation and Use of a Comet._--A _Comet_ may have been a planet by formation, and impelled, before completion, immeasurably far beyond the sun. The tail is probably the primitive atmosphere, left behind and pressed after the body as towards a sheltering wall; the _coma_ may be electric matter collected on the front, and subject to increase, which, by lessening pressure on the side facing the direction of motion, and without increased pressure on the opposite side, may cause the velocity of the planet to be subject to acceleration, or prevent the motion being equitable: the reticulated tail may serve to collect all redundant solar matter in space, after planetary use, for deposit in the solar regions, or the sun as the heart of the system, for future circulation. Were the tail to approach the earth sufficiently near, the waters of the sea would be pressed upwards as towards an immense water-spout; in which case the rivers must become drained; and as the Comet recedes from the earth, the fall of the immense column would produce _another general deluge_ over one hemisphere, at least, of the globe! The deposits from a comet's tail may occasion those nebulocities named solar spots. * * * * * THE END. * * * * * Tyler and Reed, Printers, Bolt-court, London. TRANSCRIBER'S NOTE.
