A great blazing lamp burns brilliantly in the center of the lantern of the tower, and all that part of the radiation from the flame which would naturally have beamed upward, or downward, or laterally, or back toward the land, is so turned by a curious system of reflectors and polyzonal lenses, most ingeniously contrived and very exactly adjusted, as to be thrown forward in one broad and thin, but brilliant sheet of light, which shoots out where its radiance is needed, over the surface of the sea.
They are durable, they have intensifying glasses, reflectors of the most scientific make, capital sockets in which to set a light, and a handsome lump of potentially illuminating tallow is thrown in. But, in order to see by them, the explorer must make his own candle, supply his own cohesive wick of common-sense, and light it himself. And yet the admirable thoroughness of the German intellect!
The stage curtain was up, and the only lighting on the stage came from a few incandescent lamps with weak reflectors, which cast only a narrow circle of light, which widened somewhat as the visitors' eyes learned to be content with the faint illumination. None of the men had ever before seen an empty unlighted theatre, and they felt cramped and oppressed.
The male characters, with the exception of Donatello and Hollingsworth, are not so remarkable as the feminine ones: Coverdale and Kenyon come very close together, both being artistic and both reflectors for the persons that surround them; and Dimmesdale is to some extent the same character, with the artistic escape closed upon his passions, so that they turn within and ravage his heart, arrested and altered by Puritan influences.
The diagram for the Bell-Rock reflectors was drawn by Professor Leslie, and the mould was made by Mr. Adie the optician.
On the disk resting in a little hollow in the ivory, was a pure, perfect crystal sphere of a foot diameter. He could see his reflection in it, and Yasmini's, too, the moment he entered the cave, and whichever way they moved both images remained undistorted. He suspected that the lighting and the crystal reflectors had not been arranged at random.
The palaces themselves are not lighted at night, though they have the appearance of being illuminated. Behind each window and doorway are hung strings of lights backed by reflectors. A soft glow of light comes forth, giving animation to the palaces and strengthening the picture outside.
John Dollond, the son of a Spitalfields weaver, invented the achromatic lens in 1758, removing thereby the chief obstacle to the development of the powers of refracting telescopes; James Short, of Edinburgh, was without a rival in the construction of reflectors; the sectors, quadrants, and circles of Graham, Bird, Ramsden, and Cary were inimitable by Continental workmanship.
The Trinity House having been at great pains to improve the reflecting apparatus on the coast of England, with the advice and assistance of eminent scientific men, adopted parabolic reflectors made of silvered copper; and these, from their superior effects, have ultimately been introduced into all the lighthouses of the united kingdom.
I never suffer a word to pass that may look like reflection, or possibly give the least offence, even to those who are most ready to take it. So that I hope I may with justice pronounce myself an author perfectly blameless; against whom the tribes of Answerers, Considerers, Observers, Reflectors, Detectors, Remarkers, will never be able to find matter for exercising their talents.
