Passing by the common and conceded facts of the dimensions of the planets, and the extent of their orbits, what thoughts are awakened by the suggestion that the fixed stars are the centres of other solar systems, and the eccentric comets are links to connect them all in one great and harmonious design! The astronomers tell us that some of these comets have no visible nucleuses--that the fixed stars are seen through their apparent densest parts, and that they can be nothing but luminous gases; while, on the other hand, others do betray dark compact bodies of more solid matter. Fixed stars unaccountably disappear, as if suddenly struck out of their places. Now, we know that aerolites are formed in the atmosphere by a natural process, and descend in masses of pure iron. Why may not the matter of one globe, dispersed into its elements by the fusion of its consummation, reassemble in the shape of comets, gaseous at first, and slowly increasing and condensing in the form of solid matter, varying in their course as they acquire the property of attraction, until they finally settle into new and regular planetary orbits by the power of their own masses, thus establishing a regular reproduction of worlds to meet the waste of eternity? Were the earth dissolved into gases by fusion, what would become of its satellite the moon? Might not the principles of our planet, thus volatilized, yield to its nearer attraction, assemble around that orb, which, losing its governing influence, should be left to wander in infinite space, subject to a new but eccentric law of gravity, until finally reduced again within the limits of some new system? How know we that such is not the origin of comets? Many astronomers have believed that the solar system, in company with thousands of other systems, revolves around a common centre, in orbits so vast as to defy computation, and a religious sentiment might well suggest that this centre of the universe is the throne of the Most High. Here we may fancy the Deity seated in power, and controlling, by his will, the movements of worlds, directing each to the completion of his own mysterious and benevolent designs. It certainly might be dangerous to push our speculations too far, but there can be no risk in familiarizing men to consider the omnipotence of God, and to feel their own comparative insignificance. What ideas of vastness are obtained by a knowledge of the fact that there exist stars in the firmament which ordinary telescopes show us only as single bodies, but which, on examination, by using reflectors of a higher power, are found to be clusters of orbs--clusters of worlds--or clusters of suns! These, again, are found to be _binary_ stars, or two stars revolving round each other, while they are thought, at the same time, to revolve around their central sun, and accompanied by this again, probably, to revolve round the great common centre of all!
