It is the boast of the Darwinian systematizers that their development theory not only harmonizes with, but admirably supplements and out-rounds the grander speculation of Laplace, termed the "Nebular Hypothesis," which regards the universe as having originally consisted of uniformly diffused matter, filling all space, which subsequently became aggregated by gravitation, much after the manner of Mr. Darwin's little whirligig, into an infinite number of sun-systems, occupying inconceivably vast areas in space. Of the correctness of this hypothesis it is unnecessary to speak. It is to the Darwinian speculation what the infinite is to the infinitessimal, and we only refer to it to bring out the vastness of the conception as compared to the latter theory, and to predicate thereon the more conclusive induction that an Infinite Intelligence directs and superintends all. In an area in the Milky-way not exceeding one-tenth of the moon's disc, Mr. Herschel computes the number of stars at not less than twenty thousand, with clusters of nebulae lying still beyond. As we know that no bodies shining by reflected light could be visible at such enormous distances, we are left to conclude that each of these twinkling points is a sun, dispensing light and heat to probably as many planets as hold their courses about the central orb in our own system. From the superior magnitude of many of the stars, as compared with the sun, we may reasonably infer that many of these vast sun-systems occupy a much larger field in space than our own. This would give an area in space of not less than six thousand millions of miles as the field occupied by each of these sun-systems. And as the distance between each of these systems and its nearest neighbor is probably not less than that of our sun from the nearest star, we have the enormous and inconceivable distance of not less than nineteen billions of miles separating each one of these twenty thousand stars or sun-systems, occupying a space in the heavens apparently no bigger than a man's hand. And yet Infinity, as we apprehend the term, lies beyond this vast cluster of constellated worlds! Where is Mr. Darwin's little whirligig in the comparison, or Mr. Emerson's vegetal stomach, or Mr. Herbert Spencer's "potential factors," to express the sum-total of all this totality,--this gigantic assemblage of stars clustered about a single point in the Milky-way? The human mind absolutely reels--staggers bewildered and amazed--under the load of conceptions imposed by these few twinkling stars, and is ready to exclaim,-- "Oh, star-eyed Science, hast thou wandered there, To waft us back a message of despair?"
