But further; the _number_ of these bodies is beyond the power of human calculation. Millions sink into nothing in computing it,--_thousands_ of millions are nothing. Every part of the vault of heaven contains myriads; and clusters of them have been observed which contain, within themselves, myriads more. Could we penetrate into the depths of space, as far as the eye could see--as far as thought could penetrate, we should find suns and worlds till the mind was lost in the idea of their multitude: and though we continued to move onward for ages, we should still find ourselves but on the threshold of creation. These are not the visions of speculation, but the facts of philosophy;--truths which actual observation has placed beyond a doubt. Such are, literally, the stars of heaven: myriads of myriads of suns, surrounded by ten thousand times ten thousand worlds. And let the common sense of mankind decide, whether all these can fall upon the surface of a globe not equal to the smallest of them in magnitude. But we have not yet done with this subject. Let us imagine it possible that these innumerable and enormous bodies _were_ thrown out of their stations, and by the hand of God launched towards our little world. What would result if they only came within a short distance of it? (to say nothing of their falling upon its surface.) It is well known to all who are acquainted with philosophy, that each of the heavenly bodies possesses a power called attraction, by which it draws towards itself any smaller body that comes within its sphere. So powerful is this attractive force that the sun alone draws all the worlds which move around it, and keeps them from flying off, though some are at the distance of eighteen hundred millions of miles! Each of the stars being of the same nature with our sun, possesses equally this attracting power. And were only a few of these bodies to be brought within a certain distance of the earth, the force of their combined attraction acting in contrary directions, would explode and scatter abroad, not only this earth but every earth in the system: and long before they could fall upon its surface, there would be no world for them to fall upon; it would be dissolved, and its atoms scattered through the universe.
