  • 1887 J. A. W. Oliver Earthquake Warnings in Murray’s Magazine June 817 page image

    But why should Jupiter and Saturn exercise such a particular influence on the earth when they attain these longitudes? M. Delauney answers that when in those longitudes the planets encounter meteor swarms, and just as earthquakes are rather numerous in November, when the earth passes through a meteor stream, so they reach a maximum when either of the planets undergoes the same experience. By strict parity of reasoning, it is planet-quakes that ought to ensue upon these conditions, not earthquakes; but to a bold theorist like M. Delauney that is a trifle.

    If there had been any doubt that J. Barnaby Cruikshank was up to something, his appearance would have removed it.

    Agnes drank tea and I ate cookies while Grandmother began to talk. What effect would seven moons have on a small planet? What intelligence would develop in a species without foe?
