"Dilatation" Quotes from Famous Books



... presence of a prepuce may be the inciting cause of some rheumatic affection (the writer has repeatedly seen such), just as such cases are often the result of stricture; as cases of rheumatism that have resisted all remedial means, but that have readily given way to the dilatation of a stricture, are by no means uncommon; not a mere muscular reflex rheumatic pain, but even when accompanied by a rheumatic blood condition. So that even in such a case as above reported as being due to rheumatic phlebitis, or the case reported in the fortieth ...

... 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 to believe that they are slow of growth and live many ...

... intercepted for some distance below the heart, you will at once see it almost emptied between the fingers and the heart, the blood being exhausted by the heart's pulsation, the heart at the same time becoming much paler even in its dilatation, smaller in size, owing to the deficiency of blood, and at length languid in pulsation, as if about to die. On the other hand, when you release the vein the heart immediately regains its color and dimensions. After that, if you leave the vein free and tie and compress the arteries at some distance ...

... Cilicia, a Stoic and Peripatetic, founded in Rome the sect of the Pneumatists about the year A.D. 69. It was inspired by the philosophy of Plato. The pneuma, or spirit, was in their opinion the cause of health and of disease. They believed that dilatation of the arteries drives onward the pneuma, and contraction of the arteries drives it in a contrary direction. The pneuma passes from the heart to the arteries. Their theories also had reference to the elements. Thus, the union of heat and moisture maintains ...

If it does not do so, a lateral decubitus may be tried, a position in which the intestinal regions may be very thoroughly treated, and in which, if there be gastric dilatation, the stomach-walls can be best reached. Sweeping circular frictions about the navel as a centre begin the process; the abdominal walls are then kneaded and pinched[16] with one or both hands; deep, firm kneading of the whole belly ...

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, ...

The brows are depressed, the mouth wide, but not projecting, and the nose small and well formed but for the great dilatation of the nostrils. The face is smooth, and rarely develops the trace of a beard; the hair black, coarse, and perfectly straight. The Papuan, on the other hand, has a face which we may say is compressed and projecting. ...

Air and water are two nearly identical liquid masses, entering into the composition of each other by condensation and dilatation, so that to breathe is to drink. Effluvium alone is fluid.

The southeast wind causes a mass of air, equal to the diameter of the mountain, suddenly to ascend at least three thousand feet; the dilatation produced by altitude, with its attendant cold, causes the immediate formation of a cloud on the summit; the water in the atmosphere becomes visible; successive masses of gliding-up and passing-over air ...
