"Secretion" Quotes from Famous Books



... Ashmolean museum at Oxford, a substance much resembling the horn of a goat is shown, which is said to have sprung from the forehead of a female named Mary Davis, whose likeness is there shown. The excrescence was most probably produced by a deranged secretion of the hair, and something of a similar nature may perhaps have befallen Genucius Cippus, which, of course, would be made the most of in those ages of superstition. Valerius Maximus, with all his credulity, does not say that they were real horns that made ...

... thick, tenacious matter. This change is completed, and the pustules are entirely formed, after a lapse of time from the first eruptive effort, which varies from the fifth to the ninth day, and is occasionally longer. The mean for the beginning of maturation, or the finishing of the secretion of matter in the pustule, may be received as five days for the face, and eight or nine days for the body generally. The stages of the eruption, as regards its appearance, may be very properly called papular, ...

... at the opening of the war. The people were honest in their dealings with the government, and as cheerful in their gifts to the cause as the Israelites of old in their "free will offerings" to the Lord. There were no drones among them, no secretion or dishonest division. The widows, with houses filled with orphans, gave of their scanty crops and hard labor as freely as those who owned large plantations and scores of slaves. In fact, it was noticeable that the poorer class were more patriotic and more cheerful givers, if such could be possible, ...

... the stomach, injection of the vessels and redness of the mucous lining of the stomach. This is attended by the subjective feeling of a warmth or glow within the body, and according to some, with an increased secretion of the gastric fluids. It is urged by the advocates of alcohol that this action of alcohol on the stomach is a reason for its employment as an aid to digestion, especially when the digestive powers are feeble. ...

... the honey of this tribe is almost exclusively used by the ants. But I have tasted the honey-like secretion of an Australian lecanium living; on the leaves of Eucalyptus dumosus; and the manna mentioned in Scripture is considered the secretion of Coccus manniparus (Ehrenberg) that feeds on a tamarix, and whose product is still used by the native ...

... surfaces which we assert are important. We guarantee that with a detent and spring made as we show, there will be no tendency to cockle, or if there is, it will be too feeble to even display itself. Those who have had extended experience with chronometers cannot fail to have noticed a gummy secretion which accumulates on the impulse and discharging stones of a chronometer, although no oil is ever applied to them. We imagine this coating is derived from the oil applied to the pivots, which certainly evaporates, passes into vapor, or the remaining oil could not become ...

In these cases, the tube must have been rendered more or less permanent by receiving a coating of mucus, or perhaps a genuine membranous secretion, from the body of the animal; and it may be found quite empty, or occupied by a cast of sand or mud. Of this nature are the burrows which have been described under the names of Scolithus and Scolecoderma, and probably the Histioderma of the ...

... Patience, who tilled a small farm in the state of Michigan, had a favorite cow. This creature was not a good cow, nor a profitable one, for instead of devoting a part of her leisure to secretion of milk and production of veal she concentrated all her faculties on the study of kicking. She would kick all day and get up in the middle of the night to kick. She would kick at anything—hens, pigs, posts, loose stones, birds ...

... line; and on comparing the savage with the civilized, or the infant with the adult, we see this approach of the nostrils carried furthest in the most perfect of the species. But since the septum which divides them has the function both of an evaporating surface for the lachrymal secretion, and of a ramifying surface for a nerve ancillary to that of smell, it does not disappear entirely: the integration remains incomplete. These and other like instances do not however militate against the hypothesis. They merely show that the tendency is sometimes antagonized ...

... digestion upon mental states. They show that even before the food is taken into the mouth, while the meal is still in prospect, there has been instituted a series of changes in the wall of the stomach, which gives rise to the so-called psychic secretion of gastric juice. These changes are preceded by the sensation of appetite, which is evoked not by the presence of food in the stomach—for the food has not yet been swallowed—but by the anticipation ...

... arms, which, people used to think, it stretched out like the sails of a ship, and so skimmed over the water in its shell. But this is a mistake, for it covers its shell with these arms, and in fact makes the shell by a secretion from them. It pushes itself through the water by throwing water from ...

... curious. Each grain or stone, as it is brought to the top, is covered with mortar. Without this precaution the wall would crumble into dust before reaching half an inch in height; but the insect pours over the earthen grains a sticky secretion, turning each grain round and round until it has been overspread with the gluelike liquid. Then the stone is placed with great care in the proper position, and is worked about vigorously for a moment or two until it is ...

... the refining process of Art judiciously removes from them all resemblance to Nature, I distinctly object to tears. Tears are scientifically described as a Secretion. I can understand that a secretion may be healthy or unhealthy, but I cannot see the interest of a secretion from a sentimental point of view. Perhaps my own secretions being all wrong together, I am a little prejudiced ...

... this was the beginning of the creation of all things. But it (i.e. the Desire) had no consciousness of its own creation: however, from its embrace with the wind was generated Mot, which some call watery slime, and others putrescence of watery secretion. And from this sprang all the seed of creation, and the generation of the universe. And first there were certain animals without sensation, from which intelligent animals were produced, and these were called 'Zopher-Semin,' i.e. 'beholders of the heavens;' ...

... all that this collector could ever manage to extract, the molluscous wood-destroyer being very soft and fragile. His length is about three inches, his thickness that of a small quill; he lodges in a shell of extreme tenuity, and the secretion which he ejects is, it seems, the agent which destroys the wood, and pushes on bit by bit the winding tunnel. But his doings are nothing to the working of another wafer-shelled bivalve, whose tiny habitations are so thickly imbedded ...

... procuring cause of this distressing disease is involved in considerable mystery. It seems, however, to be largely dependent on the secretion and discharge into the duodenum of an improper quantity of bile, and an irregularity in the peristaltic action of the upper part of the bowels, particularly of the duodenum, in which that action more or less is reversed, and thereby throws the biliary fluid up, through the pylorus, into the ...

... of the soul. The soul does not enter the f[oe]tus like the evil spirit into persons possessed, but is a product of the development of the brain, just as muscular activity is a product of muscular development, and secretion a product of glandular development." After a careful review of the position of recent Science with regard to the whole doctrine, Mr. Graham sums up thus: "Such is the argument of Science, seemingly decisive against a future life. As we listen to her array of syllogisms, our hearts ...

... phlox family resort to the trick of coating the upper stem and the peduncles immediately below the flowers with a sticky secretion in which crawling insects, intent on pilfering sweets, meet their death, just as birds are caught on limed twigs. Butterflies, for whom phloxes have narrowed their tubes to the exclusion of most other insects, are their benefactors; but long-tongued bees and flies ...

... undoubtedly a drunkard and a spendthrift. With an income of $10,000 a year, he was always in need. His mediocre stature, thinning locks, and undistinguished features created an impression which was confirmed by his slovenly attire and ungrammatical speech, which seemed "shackled by a preternatural secretion of saliva." Here, indeed, for ugliness and caustic tongue was "the Thersites of the law." Yet once he was roused to action, his great resources made themselves apparent: a memory amounting to genius, ...

... instincts has a circular character. Mental processes, subcortical processes, and physical effects are involved in such a way that each reenforces the others. The physical effect of the sleep instinct, comparable with the pepsin secretion in the food instinct, or with the hyperaemia of the sexual organs in the sexual instinct, is a change in the cortex by which the sensory and motor brain centers are put out of action. What kind of a change that is, is quite indifferent. ...

And is this difference of no importance? Is it not the foundation of a greater or less share of beauty in the two races? Are not the fine mixtures of red and white, the expressions of every ...

... theories—to be of single-hearted loyalty to his creed. To him as a monist, the soul (as an entity apart from the body) did not exist. Consciousness was a physical disturbance of the higher nerve centres, and thought a secretion of the brain. He acknowledged no line of demarcation between the crystal and the monera—and no chasm (of course) between man and the animals. The universe was a unit—and all its forms and forces differentiations of one substance and that substance too mysterious ...

... they would keep in good condition, and they are what in horses would be called well groomed. The skin is rubbed, cared for, kept active, because it is understood that it is an organ of sensation, of secretion, of excretion, of absorption, and of respiration. More solid matter is thrown out from the skin than from the lungs, in the proportion of eleven to seven. It is even more than the excretion ...

... like the course of our own history—has been their dispersion and their subsistence as a separate people through ages in which for the most part they were regarded and treated very much as beasts hunted for the sake of their skins, or of a valuable secretion peculiar to their species. The Jews showed a talent for accumulating what was an object of more immediate desire to Christians than animal oils or well-furred skins, and their cupidity and avarice were found ...
