I am sure that our imagination has a far narrower angle to borrow a term from the science of lenses than the imagination of men who lived in the fifteenth century. They thought of the world in its actual terms seas, islands, continents, gulfs, rivers, oceans.
Think of the great celestial eye, flint and crown glass lenses more than four feet in diameter, weighing a ton, and suspended at the end of a tube one hundred feet long! It will reach out thousands of billions of miles into space, giving us, perhaps, new secrets of the universe. Yet it is but a child's toy compared to the instruments which must follow it.
You know, Doctor, that cedar oil, which was much used in the preparation and ceremonials of the Egyptian dead, has a certain refractive power which we do not find in other oils. For instance, we use it on the lenses of our microscopes to give additional clearness of vision. Last night I put some in one of the lamps, and placed it near a translucent part of the Magic Coffer.
His idea was, that by giving a certain velocity of revolution to a series of lenses round a fixed light, as in Fresnel’s arrangement, a continuity of illuminative power, equal almost in brilliancy to that of a slowly revolving light, might be produced.
"I do not care how they look," he would say. "They probably look as they talk, without form and void." But at the moment when Maud entered his little room, he had put on his lenses to look out of the window, and he turned to see a perfect form in a closely fit ting dress, and a face pretty enough to look on with a critical pleasure.
Putting aside the excuse of fearing another crack-up, the wrecked flitter made no outstanding mark on the ground. The higher they climbed, the less it could be distinguished from the tumble of rocks about it. He had lagged a little behind and, when he hurried to catch up, found Jellico standing with his distance vision lenses to his eyes, directing them toward that shadow marking the swamp.
As soon as he had the two big objective lenses out, we had two fairly good magnifying glasses. That was a big help, but being able to see what had to be done was one thing, and having tools to do it was another. So he found a sewing kit and a piece of emery stone, and started making little screwdrivers out of needles.
He was an odd-looking chap, tall and thin, with a long, lean face under a mop of black hair that was badly in need of trimming. His near-sighted eyes blinked from behind the round lenses of a pair of rubber-rimmed spectacles and his rather nondescript clothes seemed on the point of falling off of him.
Even the glimmer of hope seemed paling in the almost supernatural eyes, that had grown prematurely womanly; viewing life no more through the rainbow lenses of sanguine girlhood, but henceforth as an anxious woman haunting the penetralia of sorrow, never oblivious of the fact that over her path hovered the gibing spectre of disgrace.
Now the lenses of the microscope bring an inverted universe to light. Men can look into a drop and discover an ocean crowded with millions of living creatures, monsters untypified in the visible world, playing about as in a great deep. Once a Roman emperor prized a mysterious jewel because it brought the gladiators contending in the arena closer to the imperial canopy.
