"Concretion" Quotes from Famous Books
 ... obstruction, over which, calling the patient's attention to the fact, he carefully guides the instrument until it drops down on the tooth-substance beyond it; then, turning the instrument and pressing it upward, he breaks off a portion of the concretion; which proves to be what is ordinarily called lime-salts, or tartar. That is the cause of the purple ring on the gum, which is merely the outward manifestation of the disease. Take it off thoroughly, polish the surface of the tooth, and in three days' time the gum will show a perfectly healthy color. ...

... obscurity. In very far-off times, when superstition and medicine went hand in hand, and charms were deemed more efficacious than drugs, a hard substance found in the intestines of goats, was greatly valued as a cure for most disorders. It was called the bezoar stone, and was a concretion chiefly of resinous bile and magnesia, and the rest inert vegetable matter. It was sold for ten times its weight in gold, and was said to come from some unknown animal, to increase the mystery belonging to it. Bezoars are now found in oxen, sheep, horses, porcupines, ...

... distant time, the question whether these so-called "fossils," were really the remains of animals and plants was hotly disputed. Very learned persons maintained that they were nothing of the kind, but a sort of concretion, or crystallisation, which had taken place within the stone in which they are found; and which simulated the forms of animal and vegetable life, just as frost on a window-pane imitates vegetation. At the present day, it would probably ...

... accumulated denudations of the mineral zones have defended themselves by strata of crystallized silicates of quartz of various thicknesses, and thus in places beneath such system of defense, or by their own concretion, have preserved in many localities a thickness of from 500 to 600 feet of conglomerate, but without this necessary cementation its further removal is very certain when again attacked by water. An example of this continuous process is ...

... gestation. The young caterpillars of the gadfly placed in the skins of cows, and the young of the ichneumon-fly placed in the backs of the caterpillars on cabbages, seem to produce their nourishment by their irritating the sides of their nidus. A vegetable secretion and concretion is thus produced on oak-leaves by the gall-insect, and by the cynips in the bedeguar of the rose; and by the young grasshopper on many plants, by which the animal surrounds itself with froth. But in no circumstance is extra-uterine gestation so exactly resembled as by the eggs ...

... Fear and Sorrow, hence Desire and Mirth; Nor can the soul, in darkness and in chains, Assert the skies, and claim celestial birth. Nay, after death, the traces it retains Of fleshly grossness, and corporeal stains, Since much must needs by long concretion grow Inherent. Therefore are they racked with pains, And schooled in all the discipline of woe; Each pays for ancient sin with ...

... most absurd mistake, but that is all. As we hinted above, he is very far from being the only scientific man who has made a mistake. Huxley had a very bad fall over Bathybius and was man enough to admit that he was wrong. Curiously enough, what Huxley thought a living thing really was a concretion, just as what Fallopius thought a concretion had ...

... quite necessary, I have avoided a pen. I have been delivered of such a quantity of chalky matter, that I am not only almost free from pain, but hope to avoid a fit this winter. How there can be a doubt what the gout is, amazes me! what is it but a concretion of humours, that either Stop up the fine vessels, cause pain and inflammation, and pass away only by perspiration; or which discharge themselves into chalk-stones, which sometimes remain in their beds, ...
