"Emission" Quotes from Famous Books



... contained in the leaves. This phosphoric acid dissolves in the water of the test glass and the latter becomes transparent again. If, now, we introduce some oxide of carbon, we remark in the sun no formation of phosphoric acid, and this proves that there is no emission of oxygen. ...

... testicles, in which the sperm-cells or spermatozoa are evolved, of a coiled duct leading there from, and of the distinctive male sex organ, the penis. This last serves the double purpose of providing an exit for the contents of the bladder and for that emission of the spermatozoa which occurs in the sex act. There are also certain glands situated in close relation to this duct which provide a fluid which is emitted at the same time as the spermatozoa, the whole being termed the seminal fluid. It is thus clear that in both sexes there are essential ...

... woman, the orgasm causes no corresponding emission of fluid, of any sort, that is jetted forth as is the semen. Yet the spasmodic action of the sexual parts, so far as nervous explosions are concerned, is exactly like that of her partner. Palpitation follows palpitation, through all the sexual ...

... these bodies from the ovum (or it may be only from the nucleus) having been accomplished, what remains of the nucleus retires from the circumference of the ovum, and is called the female pronucleus. (Fig. 33. f. pn.) The ovum is now ready for fertilization. A similar emission of nuclear substance is said by some good observers to take place also from the male germ-cell, or spermatozooen, at or about the close of its development. The theories to which these facts have given rise will be considered in future ...

... masses of metal brought to a white heat—flashes so intense that certain areas of the light became shadows by comparison, in a fiery setting from which every shadow should seemingly have been banished. No, this was no longer the calm emission of our usual lighting! This light throbbed with unprecedented vigor and activity! You sensed ...

... deceit, though at the same time, as the hour waxed and waned, I suspected in her something deeper still than disappointment and somewhat less successfully concealed. I mean a strange underlying relief, the soft, low emission of the breath that comes when a danger is past. What happened as she spent her barren hour with me was that at last she gave him up. She let him go for ever. She made the most graceful joke of it that I've ever seen made of anything; but it was for all that a great ...

Suppose, now, a second emission of paper; the same series of effects will be renewed; and so on, until the whole of the metallic money has disappeared [see Chart No. XIV, Chap. XV, for the exportation of gold from the United States after the issue of our paper money in 1862]: that is, if paper be issued of as low a denomination ...

... time. But it does not follow, because some of the laws agree with those of undulations, that there are any actual undulations; no more than it followed because some (though not so many) of the same laws agreed with those of the projection of particles, that there was actual emission of particles. Even the undulatory hypothesis does not account for all the phenomena of light. The natural colors of objects, the compound nature of the solar ray, the absorption of light, and its chemical and vital action, the hypothesis leaves as mysterious as it found them; and some ...

... came to believe in the dynamical theory of heat, is proved by the following passage taken from his notes on the Motive Power of Heat: "It would be ridiculous to suppose that it is an emission of matter, while the light which accompanies it could only be a movement. Could a motion produce matter? No! undoubtedly, it can only produce a motion. Heat is then the result of motion. It is plain then that it could be produced by the consumption ...

So, were not the beard even as the tresses in comeliness, it had not been coupled with them, O silly woman! How shall I underlie a boy, who will be hasty with me in emission and forestall me in flaccescence, and leave a man, who, when he takes breath, clips close and when he enters, goes leisurely, and when he has done, repeats, and when he pushes, pushes hard, and as often as he withdraws, returns?"

... the present. Up to a time quite within the memory of a generation still on the stage, two hypotheses about the nature of light very unequally divided the scientific world. But the small minority has already prevailed: the emission theory has gone out; the undulatory or wave theory, after some fluctuation, has reached high tide, and is now the pervading, the fully-established system. There was an intervening time during which most physicists held their opinions ...

... segment. Sometimes the luminous arc appears agitated, for hours together, by a sort of effervescence, and by a continuous change of form, before the rising of the rays and columns of light, which ascend as far as the zenith. The more intense the emission of the polar light, the more vivid are its colors, which, from violet and bluish white, pass through all the intermediate shades of green and purple-red. Sometimes the columns of light appear to come out of the brilliant arc mingled with blackish rays, resembling a thick smoke; sometimes they ...

... apparent increase of heavenly bodies near the horizon, although Bacon gives the credit of this discovery to Ptolemy. He taught, previous to the Polish physicist Witelo, that vision does not result from the emission of rays from the eye, and wrote also on the refraction of light, especially on atmospheric refraction, showing, e.g. the cause of morning and evening twilight. He solved the problem of finding the point in a convex mirror at which a ray coming from one given point shall be reflected to another ...

During the hazardous run of the torpedo-boat towards the enemy, various devices will be employed for the purpose of baffling his aim, such for instance as the emission of volumes of smoke from the bows and the erection of broad network blinds covering the sight of the little craft, but capable of being shifted from side to side, so that the enemy's marksmen may never know exactly what part of the object in sight is to be aimed at. ...

In his attacks the cancer was the result of a homosexual assault and in his intervals he elaborated theories as to the origin ...

Before a highly "fashionable" assembly of men appeared a youth in fleshings who sat down upon a stool, bared his pudenda and closed his eyes when, by "force of fancy," erection and emission took place. But presently it was suspected and proved that the stool was hollow and admitted from below a hand whose titillating ...

... mentation as the sunlight reflected from its surface. This is a considerably less exact analogy; while the nonsapient mind deals, consciously, with nothing but present sense data, there is a considerable absorption and re-emission of subconscious memories. Also, there are occasional flashes of what must be conscious mental activity, in dealing with some novel situation. Dr. van Riebeek, who is especially interested in the evolutionary aspect of the question, suggests that the introduction of novelty because of drastic ...

... and an infinitely vaster field of research. Experience has proved, for example, that some people are absolutely blind to certain colours, as red, and enjoy perfect vision relatively to yellow, to green, and to blue. If the Newtonian theory of emission be true, we must irrevocably admit that a ray ceases to be light as soon as we diminish its velocity by one ten thousandth part. Thence flow those natural conjectures, which are well worthy of experimental examination: all men do not see by the same rays; decided differences ...

The wigwam was cone-shaped, heavily thatched with reeds, having an orifice at the apex for the emission of smoke.

During their stay in the harbor they encountered an easterly storm, which continued ...

In this way he summoned the warriors and great men ...

The ancient Hebrews certainly distinguished the principle or ground of life, understanding, and will from ponderable, visible, matter. The former they considered and called 'spirit', and believed it to be an emission from the Almighty Father of Spirits: the latter they called 'body'; and in this sense they doubtless believed in the existence of incorporeal beings. But that they had any notion of immaterial beings in the sense of Des Cartes, is contrary to all we know of them, and of every other people in the ...
