Not illustrated. 1882 Excerpt: ...pass beyond the sphere of the Moon's superior attraction into the Earth's, and so would not return to the Moon, but fall instead to our globe, reaching it in about two days and a half. But there are very grave objections to this also; for we have no reason to suppose that any lunar volcano can hurl a mass of matter of such size as often falls to earth, with a velocity four times greater than a cannon ball, which would be necessary to send them to the Earth. Besides, these bodies have been falling for thousands of years, and, as already shown, in large numbers; so that did they come from the Moon, that body must be already so much reduced in size that its motions would be materially and perceptibly changed; but no such change whatever is observable in the motions of the Moon, and therefore this theory, too, has been abandoned. Still another theory is, that Aerolites are formed in the atmosphere from gases and exhalations, or the rising of very small particles from the surface of the Earth, very much aa rain, snow, and hail, are formed from the evaporations of the seas and oceans, being condensed and solidified in the upper regions of the air like them. But there is an unanswerable objection to this theory furnished by the balloonist. Aeronauts have collected portions of atmosphere at great heights, and keeping the vessel perfectly close, on reaching the surface, it has been carefully analyzed, but no such substances were ever found in the air even in minutest quantity, either at the highest altitude, or on the surface, as are found in these mineral and metallic masses so often falling on our world. But even were such substances in the air, but in exceedingly minute quantities as to prevent detection, it seems preposterous to suppose that they could be sudden...
