... his overcoat pocket, intuitively closed around his automatic revolver. A dark silhouette was outlined against the gray luminosity cast up by the lights of Broadway, half a block from the window. Through the opening another belching flame shot forth, to be answered by the criminologist's weapon, barking like a miltraileuse. They heard ...

... Cross must be withdrawn and the knowledge that Jesus lived. That inner world, to which by long effort he had learned the way, was all alight with agony; it was bitter as brine, it was of that pale luminosity that is the utmost product of pain, it hummed in his ears with a note that rose to a scream ... it pressed upon him, penetrated him, stretched him as on a rack.... And with that his will ...

... occupy the mid region of the cluster—the very locality near which, at least, must be situated this inconceivable central sun. The astronomer, perhaps, at this point, took refuge in the suggestion of non-luminosity; and here analogy was suddenly let fall. But even admitting the central orb non-luminous, how did he manage to explain its failure to be rendered visible by the incalculable host of glorious suns glaring in all directions about it? No doubt what he finally maintained was merely a centre of gravity ...

... of the images was diminished in proportion as they were nearer the eye which saw them [Footnote 22. 23: Com'e provato. See Vol. II, Nos. 874-878 and 892-901], as it has been proved in the definition of the luminosity of the moon, and of our marine horizon when the sun's rays are reflected in it and the eye which receives the reflection is remote from ...

... second place, the name heaven is applied to a body that participates in any property of the heavenly body, as sublimity and luminosity, actual or potential. Thus Damascene (De Fide Orth. ii) holds as one heaven all the space between the waters and the moon's orb, calling it the aerial. According to him, then, there are three heavens, ...

... irregularities in each case to the attraction of an invisible companion, the period of revolution of Sirius being about half a century. Later he said: "I adhere to the conviction that Procyon and Sirius form real binary systems, consisting of a visible and an invisible star. There is no reason to suppose luminosity an essential quality of cosmical bodies. The visibility of countless stars is no argument against the invisibility of countless others." This grand conception led Peters to compute more accurately the orbit, and to assign the ...

... Tests specially carried out by one of the authors to determine some of the figures required in the ensuing table show that ordinary paraffin or "wax" candles usually emit about 20 per cent. more light than that given by the standard spermaceti candle, whose luminosity is the unit by which the intensity of other lights is reckoned in Great Britain; and also that the light so emitted by domestic candles is practically unaffected by the sizes—"sixes," "eights," or "twelves"—burnt. In the sizes examined the ...

... The palpable difference of luminosity between the sun and the planets, which, as they are all made of the very same materials, and by the same process, according to this theory, ought to be equally self-luminous, is in itself a self-evident refutation of the nebular hypothesis, or of any other process of creation by mere ...

... fact that the Palace contains little American art earlier than 1905, American artists are showing marked individualities, even in their acceptance of popular precepts. The virile men of the day love luminosity; it dominates all else, and marks their canvases with light; they restrain the too bold stroke of the radical Impressionist, but outline with firmness, so that details are more easily imagined by the observer, even when an expected ...

... although there is a good deal of half-shade there are scarcely any cast shadows except on the floor; but the light on the white walls in the outside gallery is so reflected into the cast shadows that they are extremely faint. The luminosity of this part of the sketch is greatly enhanced by the contrast of the dark legs of the bench and the shadows in the roof. The warm glow of all this portion is contrasted by the grey door ...

... the battle in my brain? Not so; far away I could see faint corruscations of sparks; star shells; coloured fire balls from pistols; searchlights playing up and down the coast. Our fellows were being hard beset to hold on to what they had won; there, where the horizon stood out with spectral luminosity. What a contrast; the direct fear, joy, and excitement of the fighting men out there in the searchlights and the dull anguish of waiting here in the darkness; imagining horrors; praying the Almighty our men may be vouchsafed valour to stick it through the night; wondering, waiting until the wire ...

... not going to work this perhaps somewhat fanciful analogy to death, or pretend it is anything more than a convenient metaphor. Still, taken as such, it is not without its luminosity. For a metaphor, by supplying us with a picturable representation, often enables us really to get at the hang of the thing a vast deal better than the most solemn argument. And I fancy communities sometimes pass through just such a chrysalis stage, when it seems to the timid ...

... nucleus they were in semi-darkness—not twilight, for any ray that succeeded in penetrating was dazzlingly brilliant, and the shadows, their own included, were inky black. As they approached the farther side and the sunlight decreased, they found that a diffused luminosity pervaded everything. It was sufficiently bright to enable them to see the dark side of the meteoric masses, and, on emerging from the nucleus in total darkness, they found the shadow stretching thousands of miles before them into space. "I now understand," said Bearwarden, ...

... "picture is the logical development of light." Monticelli before him had said: "In a painting one must sound the C. Rembrandt, Rubens, Watteau, all the great ones have sounded the C." His C, his key-note, was the magic touch of luminosity that dominated his picture. Like Berlioz, he adored colour for colour's sake. He had a touch all Venetian in his relation of tones; at times he went in search of chromatic adventures, returning with the ...

... children sat there, a pale light began to blossom forth on the sky before them among the stars and extended a flat arc through them. It had a greenish tinge which gradually worked downward. But the arc became ever brighter until the stars paled in it. It sent a luminosity also into other regions of the heavens which shed greenish beams softly and actively among the stars. Then, sheaves of vari-colored light stood in burning radiance on the height of the arc like the spikes of a crown. ...

... Tarsis, and Ulysses restoring Chryseis to her father, are typical imaginary classic compositions and variations on the artist's favourite theme—the effects of sunlight on an atmosphere of varying luminosity and on the limpid, rippling waves of the sea.

... Michigan was a brightly luminous green point that must be where we were, I decided. And for some reason the colored areas representing Los Alamos and Atlantic Highlands were glowing brighter than the others—they had an active luminosity. Los Alamos was blue, Atla-Hi violet. Los Alamos was shown having more territory than I expected. Savannah Fortress for that matter was a whole lot bigger than I'd have made it, pushing out pseudopods west and ...

... extent of the nebula, as seen in a moderately good telescope. The nebula is of a faint bluish colour, impossible to represent in a drawing. Its brightness is much greater in some places than in others; the central parts are, generally speaking, the most brilliant, and the luminosity gradually fades away as the edge of the nebula is approached. In fact, we can hardly say that the nebula has any definite boundary, for with each increase of telescopic power faint new branches can be seen. There seems to be an empty space in the nebula immediately ...

His star was not dark and bright by turns—did not reveal itself in uncertain and fitful glimmerings—but shone with a full and steady luminosity across the troubled night of a nation's beginning. Under these broad and beneficent rays the Ship of State was guided, through a sea of chaos, to safe anchorage. The voyage across those seven eventful years was one that tried men's souls.

Whether to manhood hoary-headed in wisdom, or to childhood yet in soft-brained ignorance, darkness is an unpleasant fact, to be got over in the best way possible—to be got over at all events, and at any cost, and to be turned into luminosity by every expedient that can be used.

Possibly you have crude petroleum for soup and whipped salad-oil for dessert. I declare, a man living here ought to attain a high candle-power of luminosity.

We remember well the power it possessed of attracting the eye from a distance; and how, on near approach, it threw nearly all other pigments into the shade. It has in truth a lustrous luminosity not often to be met with, added to a total absence of rankness or harshness. A simple original colour, containing no base but cadmium, it is of perfect permanence, being uninjured by exposure to light, air or damp, by sulphuretted hydrogen, or by admixture. Having in common with cadmium ...

... hardness that belongs to real precious stones; for indeed she shone like a jewel, thanks to the lustre of her eyes in artificial light. Whether from humidity or some quality of their substance, I do not know, but they reflected the rays as I have rarely seen eyes do; and in their luminosity her whole face seemed to have part, so that her presence had an effect of warm brilliancy that lured and dazzled you. To see her emerge from the darkness of the Faringfield coach, or from her sedan-chair, into the bright light of open doorways and of lanterns held by servants, was to ...

With it had come that strange quality of visibility that seems to appertain to a sheeted world like an inherent luminosity; or was it perchance some vague diffusion of light from the clouded moon, skulking affrighted somewhere in the grim and sullen purlieus of the sky? She listened, thinking to hear the stir of horses in their stalls, ...

... were due principally to the greater distance of the fainter stars, then the brightness of a star would enable us to form a more or less approximate idea of its distance. But the accumulated researches of the past seventy years show that the stars differ so enormously in their actual luminosity that the apparent brightness of a star affords us only a very imperfect indication of its distance. While, in the general average, the brighter stars must be nearer to us than the fainter ones, it by no means follows that a very bright ...

... human eye there appears in space a luminous sphere that in its appointed path goes on unceasingly. The wise men are not agreed whether this apparition is merely of gaseous composition or is a solid body supplied extraneously with heat and luminosity, inexhaustibly; some argue that its existence will be limited to the period of one thousand, or five hundred thousand, or one million years; others declare that it will roll on until the end of time. Perhaps the nature of that luminous sphere will never be truly known to mankind; ...

And so, although all forms of kinetic energy (and among them zoo-dynamic, or the force of animal life) manifest warmth and luminosity as qualities, science attributes animal heat to chemic force and refuses to consider that perhaps zoo-dynamic uses chemico-dynamic for its own purposes, even if these purposes are unconscious, because the higher force always dominates the lower.
