influences. There is no end to the controversy whether the moon
influences the weather; though one would think that question, being
rather a terrestrial one, could easily be decided. Schwabe says Herschel
is wrong in saying that the years of most solar spots were fruitful; but
Wolf looks up the Zurich meteorological tables, and confirms Herschel.
In _Ferguson's Astronomy_, the standard text-book of its day, we are
informed that "Some of her mountains (the moon's) by comparing their
height with her diameter, are found to be three times higher than the
highest hills on earth." They would thus be over fifteen miles high. But
Sir Wm. Herschel assures us that "The generality do not exceed half a
mile in their general elevation." _Transactions of the Royal Society_,
May 11, 1780. Beer and Madler have measured thirty-nine whose height
they assure us exceed Mont Blanc. But M. Gussew, of the Imperial
Observatory at Wilna, describes to us, "a mountain mass in the form of a
meniscus lens, rising in the middle to a height of seventy-nine English
miles."[338] As this makes the moon lopsided, with the heavy side toward
the earth, the question of an atmosphere, and of the moon's
inhabitability is reopened; and the discussion seems to favor the man in
the moon; only he keeps on the other side always, so that we can not see
him.
The best astronomers have gravely calculated the most absurd
problems--for instance the projection of meteorites from lunar
volcanoes; Poisson calculated that they would require an initial
velocity of projection of seven thousand nine hundred and ninety-five
feet per second; others demanded eight thousand two hundred and
eighty-two; Olbers demanded fourteen times as much; but La Place, the
great inventor of the nebular theory, after thirty years' study fixed it
definitely at seven thousand eight hundred and sixty-two! It appears
that the absurdity of the discharging force of a part greater than the
attracting force of the whole never occurred to him.[339]
This same La Place supposed, that he could have placed the moon in a
much better position for giving light than she now occupies; and that
this was the only object of her existence. As this was not done he
argued that her waxing and waning light was a proof that she was not
located by an Omniscient Creator. He says he would have placed her in
the beginning in opposition to the sun, in the plane of the ecliptic,
and about four times her present distance fro
