To suppose that the eye, with its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree. p. 186.

The continual presence of one or both of the brothers at my side did not tend to alleviate the dread which the silence, the constant suspense, the cold gloom of the ever dimly-lighted chamber were calculated to arouse; for the atmosphere of unreality and gloom was upon them too, and, saving the quick, short sigh that escaped from their lips now and then, neither of them spoke nor relaxed for an instant from that strain of painful attention which had for its focus their mother's stony face.

Then, the Sciences, issuing from the focus in which they had been concentered and concealed, reappeared in all their lustre. The services they had rendered, the dangers which had threatened them, were felt and acknowledged. The plan of campaign, formed by the scientific men, called to the Committee of Public Welfare, had completely succeeded.

These wandering cells soon accumulate round the focus of infection, and form a protective barrier which tends to prevent the spread of the organisms and to restrict their field of action.

"Who is talking? I heard somebody speak? Jemima you haven't disobeyed me, have you?" Harry stepped noiselessly to the bedside and laid his fingers on the sick man's wrist: "Uncle George," he said gently. Temple lowered his head as if to focus his gaze. "Yes, there is some one!" he cried in a stronger voice. "Who are you, sir? not a doctor, are you? I didn't send for you!

All the rays that enter the eye must also pass through the crystalline lens, which brings them to a focus, as any ordinary lens would do. Now, if the media through which the light from an object passes to reach the retina were all of the same density as the air, and were also plane surfaces, an impression would be produced, but the image would not be distinct.

After that, all restraint was at an end, and each set to work to get rid of his surplus dust with the greatest rapidity possible. The focus of dissipation was the rough bar, formed by a couple of hogsheads spanned by planks, which was dignified by the name of the "Britannia Drinking Saloon."

Then the majesties of High Himalaya and the distances of star-lit night, poured forth from Dhoop Ki Dhil's lifted lips. Cadman and Skag followed her among the people going back to the village. Once she whirled with an inimitable movement, flinging her fingers toward Skag, in a gesture that seemed to focus the eyes of the whole world upon him.

This is all that is required. I mention this because I find it generally believed that a special camera is required for this work, such as to exclude all light between the negative and the lens; in my practice I have found this unnecessary. There is nothing to hinder the use of ordinary cameras, provided the draw is long enough, and the lens a short focus one.

In later years it had looked like developing into a focus of political solidity; so some ingenious commissioner had introduced the polo element, eliminating, item after item, all the rest. Then the date had been changed to the early hot weather, in order to reduce attendance; but the only effect that had was to keep away the English from outlying provinces.
