"Attenuation" Quotes from Famous Books



... pity that there is no prettier term to bestow upon a girl bachelor of any age than Old Maid.

... situation were reproduced in actuality, if ever a comet should come into collision with the earth, we can conceive two scientifically possible results. If the comet were of such attenuation, such almost infinitesimal mass as some of these celestial wanderers seem to be, we can imagine our earth self-protective and possibly unharmed. If, on the other hand, the comet had even a hundredth part of the size and solidity and ...

... the step, and their obese waists hanging over their toes—and in discourses with friends on the pavement, formulated the course of the improvident, and reduced the children's prospects to a shadow-like attenuation. The sons of these men (who wore breastpins of a sarcastic kind, and smoked humorous pipes) stared at Cytherea with a stare unmitigated by any of the respect that had formerly ...

... hundred different ways the message of sound. But this is not because words are wider in their reach and more alive; rather because they are more limited, more stereotyped, more dead. They symbolise something precise and unmistakable; but this precision is itself attenuation of the something symbolised. The exact value of the counter is better understood when it is a word than when it is a chord, because all that a word conveys has already become a thought, while all that musical sounds convey remains ...

... voice at length answered, "Come in!" There, by the window, perhaps the same where she sat so long before, crouched in an old chair covered with calico, her bent fingers striving with mechanical motion to knit a coarse stocking, sat old Mrs. Buel. Age had worn to the extreme of attenuation a face that must always have been hard-featured, and a few locks of snow-white hair, straying from under the bandanna handkerchief of bright red and orange that was tied over her cap and under her chin, added to the old-world expression of her whole figure. She was very deaf; scarcely could I ...

... same eyes, same face, the same kindly look; but the face was thinner and finer, and the brow was a student's brow, full of thought and speculation; and, looking from her hearty, vigorous form, you saw that his was slight to attenuation. ...
— What Answer? • Anna E. Dickinson

... awaits himself and other men in America as fundamentally a future in which economic prosperity will be still more abundant and still more accessible than it has yet been either here or abroad.

... attracted mine. They were a lady and a gentleman, and the latter seemed actually supporting the former, who leaned heavily upon his arm, as it appeared from her manner of carriage, so weakly and wearily she stood. Her form was extremely slight, and the outline of her countenance sharp from attenuation, and in that uncertain light, or rather shade, she looked almost as pale as the carved faces before us. The gentleman, who was of a stately height, bent over her with an anxious air, while she gazed fixedly upon the monument. Her silence seemed to oppress him, for after a minute ...

But what an attenuation was this cold pride of the dream of her youth, in which she had pictured herself walking in state towards the altar, flushed by the purple light and bloom of her own passion, without a single misgiving ...

... with thee," answered Raymond, who was greatly attracted by John's pale and thoughtful face, and could not but pity him for his manifest lack of strength and muscle. The youth was tall and rode well, but he was slight to the verge of attenuation, and the hollow cheek and unnaturally bright eyes sunk in deep caverns told a tale that was not hard to read. Young De Brocas might make a student, a clerk, a man of letters, but he would never be a soldier; and that in itself appeared to Raymond the greatest deprivation that could befall a ...

... protect against the usual virulent form exactly as vaccinia protects against small-pox. The particular disease experimented with was that infectious malady of poultry known familiarly as "chicken cholera." In October of the same year Pasteur announced the method by which this "attenuation of the virus," as he termed it, had been brought about—by cultivation of the disease germs in artificial media, exposed to the air, and he did not hesitate to assert his belief that the method would prove "susceptible of generalization"—that is to say, ...

... truth could no longer be concealed. My mother was ill, and that seriously. She still attended to her daily occupations, but she was greatly changed; she seemed during the past few weeks to have grown thin almost to attenuation. She was very pale, except at times there was a feverish glow upon her cheeks. I was then too young to detect, as I should now do, the insidious approach of that foe to human life, consumption. Going one day to ...

... these same sets of strata do not preserve their full force when followed for indefinite distances. Thus the 18,000 feet of Carboniferous grits and shales in Lancashire, before alluded to, gradually thin out, as Mr. Hull has shown, as they extend southward, by attenuation or original deficiency of sediment, and not in consequence of subsequent denudation, so that when we have followed them for about 100 miles into Leicestershire, they have dwindled away to a thickness of only 3000 feet. In the same region the ...

... Hahnemann's own words. "A long experience and multiplied observations upon the sick lead me within the last few years to prefer giving only two shakes to medicinal liquids, whereas I formerly used to give ten." The process of dilution is carried on in the same way as the attenuation of the powder was done; each successive dilution with alcohol reducing the medicine to a hundredth part of the quantity of that which preceded it. In this way the dilution of the original millionth of a grain of medicine contained in the grain ...

... influence of Johann Sebastian Bach. Of course, the grand master of fugue does not appear here, as it were, full life-size, in peruke, knee-breeches, and shoe-buckles, but his presence in spite of transformation and attenuation is unmistakable. It is, however, not only in the closeness and complexity of texture that we notice Chopin's style changing: a striving after greater breadth and fulness of form are likewise apparent, and, alas! also an increase in sombreness, ...

... mechanical difficulties intervene. The recent application of the action of bactericidal rays to the cure of lupus is, however, an extension of the same discovery.

... going on, tending to produce a separation from what may now be termed the SOLIDIFYING CRUST. During the contention between the attractions of these two bodies, or parts of one body, there would probably be a ring of attenuation between the mass and its crust. At length, when the central mass had reached a certain stage in its advance towards solidification, a separation would take place, and the crust would become a detached ring. It is clear, of course, that some law presiding over the refrigeration of heated ...

... place so rapidly, the projectile was skirting the moon's north pole at less than twenty-five miles distance. Some seconds had sufficed to plunge it into the absolute darkness of space. The transition was so sudden, without shade, without gradation of light, without attenuation of the luminous waves, that the orb seemed to have been extinguished ...
