"Porous" Quotes from Famous Books



... dissolved, leaving the ground at length entirely bare. We could now perceive the snow beginning to leave the stones from day to day, as early as the last week in April. Towards the end of May a great deal of snow was dissolved daily; but, owing to the porous nature of the ground, which absorbed it as fast as it was formed, it was not easy to procure water for drinking on shore, even as late as the 10th of June. In the ravines, however, it could be heard trickling under stones before that time; and about the 18th, many considerable streams were ...

... to prevent the escape of heat. He may think I underrate his scientific attainments, but it will do no harm to remind him that an air-tight house may be a very cold one. A man would freeze to death in a glass bottle, when a coarse, porous blanket would keep him comfortable. Double windows are not to keep cold air out, but to keep the heat in. India-rubber weather-strips have, doubtless, caused ten times as many influenzas as they have prevented. More heat will radiate through a window of ...

... not succulent green stems. After trimming off all but a few of the upper leaves, which should be clipped to reduce transpiration, the cuttings—never more than 4 or 5 inches long—should be plunged nearly full depth in well-shaded, rather light, porous, well-drained loam where they should remain undisturbed until they show evidences of growth. Then they may be transplanted. While in the cutting bed they must never be allowed to become dry. This is especially true of greenwood cuttings made during the summer. ...

... cool. Soft, yielding feather beds, in which the body sinks deeply, are very injurious, on account of the unnatural heat and perspiration they are sure to induce. It is of little consequence what the material of your bed is, if it be light, dry and porous, and not too soft. Straw, grass, husks, hair, and a great variety of other things, have been employed. Almost any thing—I repeat it—is better than feathers. The same remarks will ...

... I could hardly enter the outer edge with a boat; and it was as impossible for the ships to enter it, as if it had been so many rocks. I took particular notice, that it was all pure transparent ice, except the upper surface, which was a little porous. It appeared to be entirely composed of frozen snow, and to have been all formed at sea. For setting aside the improbability, or rather impossibility, of such huge masses floating out of rivers, in which there is hardly water for a boat, none of the productions ...

... ship may carry a cargo that floats and that is not porous, such as wood. It is impossible to sink a vessel with such a cargo by admitting water into the hold. Shots therefore must be fired at the engine and boiler rooms to force this kind of a steamer to sink. In general this is a safe rule to follow, for these are always the ...

... thirty paces, you come to a temple which is of rather larger dimensions than the one last mentioned. The columns of this were also fluted, but no part of the edifice is standing, except a solitary pilaster, which was probably a portion of the cella. These temples were built of a hard but porous stone, of a light color, and were probably covered with a thin coat of cement. They command an extensive view both of sea and land, and in their primal days must, with their tower-like columns, their sculptured ...

Since the quarrying of the rock had commenced, my work had been overseeing the native help, of which we had some fifteen cutting and hauling. In numerous places within a mile of headquarters, a soft porous rock cropped out. By using a crowbar with a tempered chisel point, the Mexicans easily channeled the rock into blocks, eighteen by thirty inches, splitting each stone a foot in thickness, so that when hauled to the ...

But I do not mean by "stony soils" land on which many stones are lying, for on that very account it may be most suitable; but I mean land which shows a pebbly stratum just below the surface, or such as is of a porous, stony nature. In the choice of situation care must be taken to select that which is as much as possible protected against the south-east wind, because its dry influence is very injurious to the coffee plant, and also prevents the growth of the ...

... miles of latitude, on a south-east course: this may give about one sponge for every two miles. The word "Bog" conveys much of the idea of these earthen sponges; but it is inseparably connected in our minds with peat, and these contain not a particle of peat, they consist of black porous earth, covered with a hard wiry grass, and a few other damp-loving plants. In many places the sponges hold large quantities of the oxide of iron, from the big patches of brown haematite that crop out everywhere, and streams of ...

... in the chalk hills just beneath the high cliffs of Beachy Head. Beyond the Downs again, to the north, the country descended abruptly to the deep trough of the Weald, whose cold and sticky clays or porous sandstones are never of any use for purposes of tillage. Hence, as its very name tells us, the Weald has always been a wild and wood-clad region. The Romans knew it as the Silva Anderida, or forest of Pevensey; the early English as the Andredesweald. Both names are derived from a Celtic root signifying ...

... remarked elsewhere on the difference observed by Herodotus on a battle-field between the skulls of the Persians and those of the Egyptians. Since it is desirable that the bones of the skull should grow harder and more substantial, less fragile and porous, not only to protect the brain against injuries but against colds, fever, and every influence of the air, you should therefore accustom your children to go bare-headed winter and summer, day and night. If you make them wear a night-cap to keep their hair clean ...

That which is bright, hard, and clean, is best; and that which is soft, porous, and covered with damp dust, is poor. It will be well to provide two barrels of charcoal, for kindling, to every ton of anthracite coal. Grates, for bituminous coal, should have a flue nearly as deep as the grate; and the bars should be round, and not close together. The ...

The body is cooled by rapid evaporation, on the familiar principle of a tropical water bag that is porous enough to let some of the water exude.
