planet was snuffed out at once on leaving the sun's body. Things were somewhat different with the planet Venus.
Venus had for many years been the object of close research by Schroeter, a most painstaking observer of Lilienthal, then a well-known observatory in the duchy of Bremen. Her appearance had also been carefully studied by Herschel for nearly twenty years. The former made out that he had measured on her surface lofty mountains six times higher than Chimborazo, or about twenty-three miles in height. The latter could see nothing of the kind, and poked some grave scientific fun at his friend, who complained, in a learned paper, that he could not "reconcile it to the friendly sentiments which the author has always hitherto expressed towards me, and which I hold extremely precious; though perhaps to others it may not have the same appearance." Boscovich's epigram on the planets had come true in the case of these astronomers—
" 'Twixt Mars and Venus as this globe was hurled,
'Tis plain that love and war must rule the world."
Schroeter attacks Herschel for misrepresenting, or, on insufficient grounds, rejecting his views. Herschel appears not to have retorted any more than he did when attacked elsewhere by others. It was wise; but he found that the Lady Venus may be as much a source of quarrel, when she walks in unsurpassed brightness among the stars, as when she awakens the feelings of mortal hearts on earth.
As this was the only scientific quarrel in Herschel's life, it is worth while to show how small it was. Far different were the quarrels which caused annoyance
