 ... is to be done?" True for her that there followed gentle feelings, and gentler yet in her attendance on her patron's obsequies, in the discovery that all of which he died possessed he'd left to her, but it is the duller surfaces that are slowest to give refraction, the least used springs that are least pliant. She was come a long road from her first signs of hardening. She was past, now, the stage where, when grieving for the little old man, she would have felt contrition that her first thought at his ...

... a curious sensation of having stepped into an old Flemish painting. The hall in which he stood was cool and rather dark, though a bright refraction of light tossed from some upper window upon a tall mirror filled the shadow with broken spangles. Through an open doorway at the rear was the green glimmer of a garden. In front of him was a mahogany sideboard. On its polished top lay two books, a box of cigars, and a cut glass decanter ...

... active in its subtle (four-dimensional) vehicle, and ranges free throughout the ampler spaces of this subtler world. In deep sleep, consciousness reverts to its pure condition—the individual self becomes the All-Self: the rainbow, no longer prismatic by reason of its refraction in materiality, becomes the pure white light; the melody of life resolves itself into the primordial harmony; sequence becomes simultaneity, and Time, no longer "besprent with seven-hued circumstance," ...

... musical execution. Similarly the Adagio, developed, as Beethoven has developed it in the third movement of his Ninth Symphony, may be taken as the basis of all regulations as to musical time. In a certain delicate sense the Allegro may be regarded as the final result of a refraction (Brechung) of the pure Adagio-character by the more restless moving figuration. On careful examination of the principal motives of the Allegro it will be found that the melody (Gesang) derived from the Adagio, predominates. The most important ...

They have usually been attributed to a refraction, by which a section of the bordering sky is thrown below the horizon; but I am convinced that they are the effect of reflection. It seems that a gas (emanating probably from the heated earth and ...

What chance has one to detect a machine that is perfectly transparent when there is nothing but perfectly transparent air around it? It is a curious property of this vibrational system of invisibility that the index of refraction is made very low. It is not the same as that of air, but the difference is so slight that it is practically within the limits of observation error; so small is the difference that there is no 'rainbow' effect. The difference of temperature of the air would ...

The sun was hot and dazzling; and as the bright scarlet was magnified by refraction, I fancied for a long time they were flamingoes. This fancy was dissipated as I drew near. The outlines of the bills, like the blade of a sabre, convinced me they were the ibis; besides, I now saw that they were less than three feet in height, while the flamingoes ...

The immensity of the history which has been crowded into those forty-five years has distorted our mental vision, as ordinary objects are sometimes distorted by refraction. Yet when we reflect, the distortion disappears. But the wonder still remains. The years during which the deeds of Lincoln have been a memory to us do not carry us back to the early days of our own country. They do not carry us back even to the time ...

A person would be tempted there to take the altitude of the sun with a quadrant, if the horizon of the land were not constantly misty on account of the variable effects of refraction.

There is, moreover, another element of error due to the refraction of light by the earth's atmosphere.

I determined to go home and place myself in the same position—as regards the mirror—and if the same effect was produced, I would make up my mind that it was the natural result of some principle of refraction or optics, which I did not understand, and dismiss it. I tried the experiment with the same result; and as I had said to myself, accounted for it on some principle unknown to me, and it then ceased to trouble me. But the God who works through the laws of nature, might surely give ...

Nothing was visible but the flat beds of mud; the day was not very clear, and there was much refraction, or, as the sailors expressed it, "things loomed high."

... curious freak of nature, the tendency of the channel of the Mississippi is always toward one or the other of its banks, being influenced by the direction of its bends. The principle is one of nicely regulated refraction. If the river were perfectly straight, the gravity and inertia of its waters would move in a right line, with a velocity beyond all control. But we find the river very sinuous, and the momentum of current consequently lessened. ...

There are similar dangers of illusion to those who have developed spiritual sight, until they have been trained to discount the refraction and to view the life which is permanent and stable, disregarding the form which is evanescent and changeable. The danger of getting things out of focus always remains however and is so subtle that the writer feels an imperative ...
