Quotes
Quotes by authors and personalities

  1. While strolling around, we kept the run of the moon all the time, and we still kept an eye on her after we got back to the hotel portico. I had a "theory" that the gravitation of refraction, being subsidiary to atmospheric compensation, the refrangibility of the earth's surface would emphasize this effect in regions where great mountain ranges occur, and possibly so even-handed impact the odic and idyllic forces together, the one upon the other, as to prevent the moon from rising higher than 12,200 feet above sea-level. This daring "theory" had been received with frantic scorn by some of my fellow-scientists, and with an eager silence by others.
