quakes the [p. 239] Our data: dragged down from ponds or other worlds that have been quaked, when only a few miles away, by this earth, some other world also quaking this earth. In a way, or in its principle, our subject is orthodox enough. Only grant proximity of other worlds--which, however, will not be a matter of granting, but will be a matter of data--and one conventionally conceives of their surfaces quaked--even of a whole lake full of fishes being quaked and dragged down from one of them. The lake full of fishes may cause a little pain to some minds, but the fall of sand and stones is pleasantly enough thought of. More scientific persons, or more faithful hypnotics than we, have taken up this subject, unpainfully, relatively to the moon. For instance, Perrey has gone over 15,000 records of earthquakes, and he has correlated many with proximities of the moon, or has attributed many to the pull of the moon when nearest this earth. Also there is a paper upon this subject in the Proc. Roy. Soc. of Cornwall, 1845. Or, theoretically, when at its closest to this earth, the moon face of this earth, and is itself quaked--but does not itself fall to this earth. As to showers of matter that may have come from the moon at such times--one can go over old records and find what one pleases. That is what we now shall do. Our expressions are for acceptance only. We take them from four classes of phenomena that have preceded or accompanied earthquakes: Unusual clouds, darkness profound, luminous appearances in the sky, and falls of substances and objects whether commonly called meteoritic or not. Not one of these occurrences fits in with principles of primitive, or primary, seismology, and every one of them is a datum of a quaked body passing close to this earth or suspended over it. To the primitives there is not a reason in the world why a convulsion of this earth's surface should be accompanied by unusual sights in the sky, by darkness, or by the fall of substances or objects from the sky. As to phenomena like these, or storms, preceding earthquakes, the irreconcilability is still greater.
