"The fall of meteoric stones was occasionally reported by good witnesses during many ages. But science did not understand how stones should be formed in or beyond the atmosphere... The accounts of the fall of meteoric stones were held to be incompatible with the laws of nature, and specimens which had been seen to fall by hundreds of people were preserved in cabinets of natural history as ordinary minerals, 'which the credulous and superstitious regarded as having fallen from the clouds.' A committee of the French Academy of Sciences, including the celebrated Lavoisier, unanimously rejected an account of three nearly contemporary descents of meteorites which reached them on the strongest evidence. After two thousand years of incredulity, the truth in this matter was forced upon the scientific world about the beginning of the present century. There would have been at any time, of course, an instant cessation of skepticism if any one could have shewn, a priori, from ascertained principles in connection with the atmosphere, how stones were to be expected to fall from the sky. But what is this but to say that facts by themselves, however well attested, are wholly useless in such circumstances to the cultivators of physical science, while any kind of vague hypothesis can be brought forward in opposition to them? What is it but to put conjecture or prejudice above fact, and indeed utterly to repudiate the Baconian method?"

“The facts, indeed, connected with this gloomy department of statistics show that the most valuable period of human life—that in which a man is producing more than he is consuming—is that which provides the greatest number of victims.”

“Indifference to life and indifference to the purity and amenity that sweeten existence must necessarily go together.”

“Seeing in our astral system many thousands of worlds in all stages of formation, from the most rudimental to that immediately preceding the present condition of those we deem perfect, it is unavoidable to conclude that all the perfect have gone through the various stages which we see in the rudimental. This leads us at once to the conclusion that the whole of our firmament was at one time a diffused mass of nebulous matter, extending through the space which it still occupies. So also, of course, must have been the other astral systems. Indeed, we must presume the whole to have been originally in one connected mass, the astral systems being only the first division into parts, and solar systems the second.”

“The elder Herschel, directing his wonderful tube towards the sides of our system, where stars are planted most rarely... was enabled with awe struck mind to see suspended in the vast empyrean astral systems, or, as he called them, firmaments, resembling our own. Like light cloudlets to a certain power of the telescope, they resolved themselves, under a greater power, into stars, though these generally seemed no larger than the finest particles of diamond dust. The general forms of these systems are various; but one at least has been detected as bearing a striking resemblance to the supposed form of our own. The distances are also various... The farthest observed by the astronomer were estimated by him as thirty-five thousand times more remote than Sirius, supposing its distance to be about twenty thousand millions of miles. It would thus appear, that not only does gravitation keep our earth in its place in the solar system, and the solar system in its place in our astral system, but it also may be presumed to have the mightier duty of preserving a local arrangement between that astral system and an immensity of others, through which the imagination is left to wander on and on without limit or stay, save that which is given by its inability to grasp the unbounded.”

“All, we see, is done by certain laws of matter, so that it becomes a question of extreme interest, what are such laws? All that can yet be said, in answer, is, that we see certain natural events proceeding in an invariable order under certain conditions, and thence infer the existence of some fundamental arrangement which, for the bringing about of these events, has a force and certainty of action similar to, but more precise and unerring than those arrangements which human society makes for its own benefit, and calls laws. It is remarkable of physical laws, that we see them operating on every kind of scale as to magnitude, with the same regularity and perseverance.”

“Ascending to the next group of rocks, we find the traces of life become more abundant, the number of species extended, and important additions made in certain vestiges of fuci, or sea plants, and of fishes. This group of rocks has been called by English geologists, the Silurian System, because largely developed at the surface of a district of western England, formerly occupied by a people whom the Roman historians call Silures.”
