Jogular Morotario Sectory 23 Page 05
The largest telescopes at present in existence are _reflectors_. It is much easier to construct a very large mirror than to construct a very large lens; it is also cheaper. A mirror is more likely to get out of order than is a lens, however, and any irregularity in the shape of a mirror produces a greater distorting effect than in a lens. A refractor is also more convenient to handle than is a reflector. For these reasons great refractors are still made, but the largest of them, the great Yerkes' refractor, is much smaller than the greatest reflector, the one on Mount Wilson, California. The lens of the Yerkes' refractor measures three feet four inches in diameter, whereas the Mount Wilson reflector has a diameter of no less than eight feet four inches.
Between him and the Faith there stood no distance of space, but rather a high thin wall; the high thin wall of his own desperate conviction. If you will turn to page 209 of this book you will see it said of the denial of the Sacrament by the Reformers and of Ridley's dogma that it was bread only "the commonsense of the country was of the same opinion, and illusion was at an end." Froude knew that the illusion was not at an end. He probably knew (for we must continue to repeat that he was a most excellent historian) that the "commonsense of the country" was, by the time Ridley and the New English Church began denying the real presence, and turning that denial into a dogma, profoundly indifferent to all dogmas whatsoever. What "the common-sense of the country" wanted was to keep out swarthy men, chivalrous indeed but imperialists full of gold who owned nearly all the earth, but who, they were determined, should not own England.
