Now the keen eyes of young America, by aid of the magnifying lens supplied by Emmanuel Schilsky, would detect the land of the free to be in fact a land of greedy and unscrupulous tyrants; the home of the brave a home of economic serfs.
"An English gentleman, whose name at present escapes me, obtained a copy of Daguerre's book about the same time with myself. He commenced experimenting also. But an American of the name of Walcott was very successful with a modification of Daguerre's apparatus, substituting a metallic reflector for the lens.
Then a dim shape took form upon the floor, more and more distinctly until the dissolving lens brought a man's body into clear view, a body stretched face downward in a dark red pool that grew and widened, slowly straining and wetting the polished wood. "Groener," said the magistrate, his voice strangely formidable in the shadows, "do you recognize this room?"
What remains after this scouring process, or what oozes from the band before it has set, spreads over the sides of the nest in a thin layer of bubbles so fine that they cannot be distinguished without the aid of a lens. We often see a torrent of muddy water, full of clay in suspension, covered with great streaks and masses of foam.
Now, at Teneriffe, the black rapilli extend from the foot of the Peak to the sea-shore; while the white ashes, which are only pumice ground to powder, and among which I have discovered, with a lens, fragments of vitreous feldspar and pyroxene, exclusively occupy the region next to the Peak.
The thin, muscular ring which lies between the cornea and crystalline lens, giving the eye its special color. A disorder in which the skin and eyes assume a yellowish tint. The process by means of which the more complex elements are rendered more simple and less complex. The opposite of anabolism. Labyrinth. The internal ear, so named from its many windings.
Why does not the inverted image on the retina cause us to see objects upside down? What change occurs in the shape of the crystalline lens when we look from distant to near objects? From near to distant objects? Why are these changes necessary? How are they brought about?
And it's for that, perhaps, that I'm spoiling my eyesight now, grinding and grinding and grinding at this very lens, and fitting the thing to an accurate fraction of a millimetre, as we always fit these things we who are careful and honest workmen to show an idle man's friends the hairs on a flea's fore-leg.
A couple of peasant hand-carts were tilted on end, and the flooring sodded like the barrels. "Look who's coming," pointed Rossiter, swiveling his lens sharply around. Steaming gently into our narrow street from the Grand Place came a great Sava mitrailleuse big steel turret, painted lead blue, three men sitting behind the swinging turret.
Now, the slightest bending of a mirror is fatal to its performance, the effect being doubled by reflection; while in a lens alteration of figure is compensated by the equal and contrary flexures of the opposing surfaces, so that the emergent beams pursue much the same paths as if the curves of the refracting medium had remained theoretically perfect.
