"Dilatation" Quotes from Famous Books
... distended it, and the natural elasticity of the parts, aided by the contraction of the abdominal muscles; the thorax being thus diminished, a quantity of air is expelled from the lungs. The muscles which distend the thorax beginning again to act, the air reenters; and this alternate dilatation and contraction, is called respiration. The entrance of the air into the lungs, is termed inspiration, and its ... — Popular Lectures on Zoonomia - Or The Laws of Animal Life, in Health and Disease • Thomas Garnett
... groups as compared with each other; they stand on one structural level, though with different tendencies,—the body in Mollusks having always a soft, massive, concentrated character, with great power of contraction and dilatation, while the body in Articulates has nothing of this compactness and concentration, but on the contrary is usually marked by a conspicuous external display of limbs and other appendages, and by a remarkable elongation of the body,—that feature ... — The Atlantic Monthly, Vol. IX., March, 1862., No. LIII. - A Magazine Of Literature, Art, And Politics, • Various
... minimum resistance. At a pressure of 0.0055 mm., 0.066 millionth, the highest exhaust obtained in any of the experiments, even a one-inch spark from an induction coil refused to pass. It was also ascertained that there is neither condensacian nor dilatation of the gas in contact with the terminals prior to the passage of ... — Scientific American Supplement No. 275 • Various

... that every act of mental volition is united in nature to a certain given motion of the gland. For instance, whenever anyone desires to look at a remote object, the act of volition causes the pupil of the eye to dilate, whereas, if the person in question had only thought of the dilatation of the pupil, the mere wish to dilate it would not have brought about the result, inasmuch as the motion of the gland, which serves to impel the animal spirits towards the optic nerve in a way which would dilate or contract ... — Ethica Ordine Geometrico Demonstrata - Part I: Concerning God • Benedict de Spinoza
... very sultry. I commenced a series of observations with a syphon barometer (made by Bunten of Paris). The table for expansion of mercury and mean dilatation of glass, sent me by my friend Captain P. P. King, came but to 88 deg. of Fahrenheit, whereas at 4 P.M., the centigrade thermometer stood at 441/2 deg., which is equal to 112 ... — Journal of an Expedition into the Interior of Tropical Australia • Thomas Mitchell

... alimentary canal; the heart and liver; the blood-vessels, branching from either side of the heart to join the gills; and a fleshy muscle passing from one valve of the shell to the other, enabling the animal by its dilatation or contraction to open and close its shell at will. A cut across an animal of this class will show us better the bilateral arrangement of the parts. In such a section we see the edge of the two shells on either side; within these the edge of the mantle; then ... — Atlantic Monthly, Vol. 9, No. 52, February, 1862 • Various
... murderous perspective, before the doing of the deed, however subtle the precautions for its commission, would have been closed up by a gigantic dilatation of the hateful figure, preventing her from seeing any consequences beyond it; and as those consequences would have rushed in, in an unimagined flood, the moment the figure was laid low—which always happens when a murder is done; so, now she sees that when he used to be on the watch before her, ... — Bleak House • Charles Dickens
... descends from the belly into the pouch by one of the teats, which are there deposited. On this difficulty as I can throw no light, I shall hazard no conjecture. It may, however, be necessary to observe that the teats are several inches long and capable of great dilatation. And here I beg leave to correct an error which crept into my former publication wherein I asserted that, "the teats of the kangaroo never exceed two in number." They sometimes, though rarely, amount to four. There is great reason ... — A Complete Account of the Settlement at Port Jackson • Watkin Tench
... ANEURISM (from Gr. [Greek: aneurisma], a dilatation), a cavity or sac which communicates with the interior of an artery and contains blood. The walls of the cavity are formed either of the dilated artery or of the tissues around that vessel. The dilatation of the artery is due to a local weakness, the result of disease or injury. The commonest ... — Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1 • Various
... disease. When the patient cannot bear to be raised up in bed without great uneasiness, it is a bad symptom. So I believe is deafness, which is commonly mistaken for stupor. See Class I. 2. 5. 6. And when the dilatation of the pupil of either eye, or the squinting is very apparent, or the pupils of both eyes much dilated, it is generally fatal. As by stimulating one branch of lymphatics into inverted motion, another branch is liable ... — Zoonomia, Vol. II - Or, the Laws of Organic Life • Erasmus Darwin
... perfectly used; the strain upon the emphysematous parts being thereby relieved, the patient ultimately breathes with greater comfort, and the bronchitis is in time removed. Where old, chronic bronchitis with emphysema exists there is frequently marked dilatation of the right side of the heart, in which case a patient should by all means ... — The Truth About America • Edward Money
... ascending to 14,000 feet, owing to the diminished supply of oxygen, exercise brings on vertigo and headache; ascending higher still, lassitude and tension across the forehead ensue, with retching, and a sense of weight dragging down the stomach, probably due to dilatation of the air contained in that organ. Such are the all but invariable effects of high elevations; varying with most persons according to the suddenness and steepness of the ascent, the amount and duration of exertion, and the length ... — Himalayan Journals (Complete) • J.

... little reliance can be placed on the testimonies in its favour; and, in modern practice, it is little employed. It appears to have a peculiar action on the eye: hence it has been used in amaurosis; and from its power of causing dilatation of the pupil, when topically applied under the form of infusion, it has been used before performing the operation for cataract. A practice which is hazardous, as the pupil, though much dilated by the application, instantly contracts when the instrument is introduced. When given ... — The Botanist's Companion, Vol. II • William Salisbury

... always distinguish between mere strangeness and that novelty which is so agreeable as to cheat us with some charm of seeming association. He had not the concentrated power which can sometimes pack infinite riches in the little room of a single epithet, for his genius is rather for dilatation than compression.[287] But he was, with the exception of Milton and possibly Gray, the most learned of our poets. His familiarity with ancient and modern literature was easy and intimate, and as he perfected himself in his art, he ... — Among My Books • James Russell Lowell
... present, but it was not certain that the development of this was not antecedent to the injury, as the patient did not notice it until his attention was drawn to its existence. In none of the cases under observation in South Africa had enough time elapsed for sufficient dilatation of the artery above the point of communication to give rise to any confusion from this cause as to the ... — Surgical Experiences in South Africa, 1899-1900 • George Henry Makins
... formed under pressure. In the glaciers we have the two processes combined. But the investigators of glacial phenomena have considered too exclusively one or the other: some of them attributing glacial motion wholly to the dilatation produced by the freezing of infiltrated moisture in the mass of snow; others accounting for it entirely by weight and pressure. There is yet a third class, who, disregarding the real properties of ice, would have us believe, that, ... — Atlantic Monthly, Volume 12, No. 73, November, 1863 • Various
... stinking beetle with clubbed antennae. It is curious to see how these clubbed antennae are imitated by an insect belonging to a group with long slender antennae. The sub-family Anisocerinae, to which Cyclopeplus belongs, is characterised by all its members possessing a little knob or dilatation about the middle of the antennae. This knob is considerably enlarged in C. batesii, and the terminal portion of the antennae beyond it is so small and slender as to be scarcely visible, and thus an excellent substitute is obtained for the short clubbed antennae ... — Contributions to the Theory of Natural Selection - A Series of Essays • Alfred Russel Wallace
... by the aid of small metal spheres fixed in tubular supports by movable levers to which are communicated the motions of compression and dilatation of the air in the pump chamber. They oscillate in a plane whose direction may be varied according to the arrangement of the sphere, as seen in the two apparatus of this kind shown in Fig. 1. Fig. 2 will give an idea of the general arrangement. The two pistons of the air-pumps ... — Scientific American Supplement, No. 315, January 14, 1882 • Various
... lengthens, and forces its companion to form a kind of interior annulus of a circle on the left. When the air is dry, it contracts, draws its companion to the right, and becomes itself the interior annulus. In order to show this dilatation and contraction, an index is fixed on the upper end of two of the slips; a plate of metal or wood is fastened to the front of the plinth, so as to cover the two slips from the eye. A slit, being nearly the portion of a circle, is cut in this plate, so that the shank ... — The Writings of Thomas Jefferson - Library Edition - Vol. 6 (of 20) • Thomas Jefferson
... the cause, it appears; the cause withdrawn, it disappears; the weakness or intensity of the cause is the measure of its own weakness or intensity. It is bound to that like any physical phenomenon to its condition, like dew to the chilliness of a surrounding atmosphere, like dilatation to heat. Couples exist in the moral world as they exist in the physical world, as rigorously linked together and as universally diffused. Whatever in one case produces, alters, or suppresses the first term, produces, alters, and suppresses the second term as a necessary ... — Prefaces and Prologues to Famous Books - with Introductions, Notes and Illustrations • Charles W.

... cele, and, though the name is common to them, they differ very much from one another." Some of them are fatty, some of them are pultaceous, some of them are cancerous, and some of them he calls honey tumors, because of a honey-like humor they contain. "Sometimes they are due to a local dilatation of the blood vessels, and this is most frequently connected with parturition, apparently being due to the drawing of the breath being prevented or repressed during the most violent pains of the patient. Such local dilatation at this point of the veins ... — Old-Time Makers of Medicine • James J. Walsh
