"Umbra" Quotes from Famous Books



... multitudinous bright lines, instead of a rainbow-tinted spectrum crossed by multitudinous dark lines. It is, indeed, only by contrast that the dark lines appear dark, just as it is only by contrast that the solar spots seem dark. Not only the penumbra but the umbra of a sun-spot, not only the umbra but the nucleus, not only the nucleus but the deeper black which seems to lie at the core of the nucleus, shine really with a lustre far exceeding that of the electric light, though by contrast with the rest of the sun's surface ...

... trencher and all. This chimney is more voracious than the sea. Give time enough, and all which yonder depths contain might pass through this insatiable throat, leaving only a few ashes and the memory of a flickering shade,—pulvis et umbra. We recognize this when we have anything to conceal. Deep crimes are buried in earth, deeper are sunk In water, but the deepest of all are confided by trembling men to the profounder secrecy of flame. If every old chimney could narrate the fearful deeds ...

... reason for the depression which one of these dark spaces exhibits. In a whirlwind, as in a whirlpool, the vortex will be below the general level, and all around, the surface of the medium will descend toward it. Hence a spot seen obliquely, as when carried toward the Sun's limb, will have its umbra more and more hidden, while its penumbra still remains visible. Nor are we without some interpretation of the penumbra. If, as is implied by what has been said, the so-called "willow-leaves," or "rice-grains," are the tops ...

He scouted the idea that they were under any sort of compulsion when they wrote or that they were pulling his leg. One must anyhow congratulate them ...

She told Nawasa that she was afraid to go with me, as she was afraid that I would take her to Mexico and sell her for a slave, where she would have to work in the fields. But Nawasa assured her there was no danger, saying: "Esta umbra mooly ah-me-go," meaning, "This man is a great friend of mine;" and she again told her not to be afraid, for I would take her to her ...

Dawes, one of many clergymen eminent in astronomy, observed, in 1852, with the help of a solar eye-piece of his own devising, some curious details of spot-structure.[405] The umbra—heretofore taken for the darkest part of the spot—was seen to be suffused with a mottled, nebulous illumination, in marked contrast with the striated appearance of the penumbra; while through this "cloudy stratum" a "black opening" permitted the eye to divine farther unfathomable depths beyond. ...

Why should we confess it in the general, yet promptly and pointedly deny it in every particular, if our hearts retained more than the "magni nominis umbra," when we preached up the Protestant principle?
