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
