"Silicious" Quotes from Famous Books
 ... down by it. An angular fragment of stone in the course of ages moved in the cavity of a rock makes a deep round excavation, and is worn itself into a spherical form. A torrent of rain flowing down the side of a building carries with it the silicious dust, or sand, or matter which the wind has deposited there, and acts upon a scale infinitely more minute, but according to the same law. The buildings of ancient Rome have not only been liable to the constant operation of the rain-courses, or minute torrents produced by ...

... could not have been performed in a more refractory stone. Not a great distance away are the Monte Alban ruins, as described, which, although extensive and remarkable, show nothing of exact and intricate work in stone-shaping. The hard or silicious rocks which form the immediate region, and the quartzite and crystalline limestone, did not lend themselves, either in the quarry or under the chisel, to such work. In Chiapas, the unshaped and uncoursed ...

... question to inquire which of the springs and water currents of this region are now making deposits that can be compared with those which filled the Comstock and other veins. No one who has visited that country will hesitate to say the hot and not the cold waters. The immense silicious deposits, carrying the ores of several metals, formed by the geysers of the Yellowstone, the Steamboat Springs, etc., show what the hot waters are capable of doing; but we shall search in vain for any evidence that the cold ...

... matter at all, and science finds no stumbling-block in the way of a complete explication of this riddle, if, in the light of nature, there be any such riddle. We claim there is not, when we interpret nature in the light of nature's God. Let the earth, or rather its silicious and other decaying rocks, bring forth these batrachian forms. The command is imperative and not dependent upon any "seed" previously scattered or sown in ...

... composition of wheaten straw; and it is worthy of remark that, in most cases where fire is purposely generated by the agency of thermo-dynamics, some form of silex is enlisted—flint, for instance, or the silicious covering of endogenous plants, such as bamboo, and so forth. A theory ...

... found numerous silver, tin, and copper mines that had been worked by them. All the deep, winding galleries of these mines were driven without the aid of iron, steel, or gunpowder. It is said that an alloy of tin and copper was used for their edge-tools; and with the aid of a silicious sand or dust, they were enabled to cut and polish amethysts, emeralds, porphyry, and other hard substances. With these implements the elaborate carving in the stone temples of Palenque and the other ruined cities of ...

... America. The tribes quarried by means of crowbars and picks of wood and bone. They split the silicious rocks with stone hammers, and then chipped them into shape with bone tools. Soapstone for pottery was partly cut into the desired shape in the native ledge, broken or prised loose, and afterwards scraped into form. Paint was excavated with ...

... light and friable, and below lay a bed of silicious tufa; therefore, even without tools, the aperture deepened quickly. It soon became evident that a man, or men, clinging to the sides of the "pah," were cutting a passage into its exterior wall. What could be the object? Did they know of the existence of the prisoners, or ...

... the "countless stones" consist of a silicious sandstone of the Eocene period, overlying the chalk, and are identical with the "Sarsens," or "Grey Wethers," which occur at the pre-historic town of Avebury, and at Stonehenge; the smaller stones of the latter are, however, of igneous origin, and "are believed by Mr. ...

... exegetical? How glad I shall be if you can assure me that it is! But, nonsense apart and begged pardon for, pray write me a line to say how you are, directing to this pretty place. "The soil is in general a moist and retentive clay, with a subsoil or pan of an adhesive silicious brick formation; adapted to the growth of wheat, beans, and clover—requiring, however, a summer fallow (as is generally stipulated in the lease) every fourth year, etc." This is not an unpleasing style on agricultural ...

... paper, or an old soft silk handkerchief, nor any other such material to wipe the lenses, as is usually advised. It is not, however, these wiping materials that do the mischief, but the dust particles on the lenses, many of them perhaps of a silicious nature, which are always harder than optical glass, and as these particles attach themselves to the wiping material they cut microscopic or greater scratches on the surfaces of the objective in the process ...

... in order to make up the skeleton. The skeleton of calcareous sponges consists of a number of spicules composed of carbonate of lime. These spicules are of very varied though regular shape, but ordinarily assume a rod-like needle shape or else a stellate form. In silicious sponges the spicules are composed of silica, and are generally deposited around axial rods in concentric layers. The spicules are joined together and cemented by a body that has been named "spongin," ...

... less long and tenacious. It is from the liber that our most valuable commercial fibers are obtained. In some plants the fibrous system prevails throughout the inner bark; but what we wish to refer to more particularly at present is a remarkable example of the harder and more silicious barks, and which is to be found in the "Pottery Tree" of Para. This tree, known to the Spaniards as El Caouta, to the French as Bois de Fer, to the Brazilians as Caraipe, is the Moquilea utilis of botanists, and belongs to the ...

... the earth, by what vessels is it conveyed to the surface of the plants? and, in addition, if earth be its source, how is it that earth-seeking, and hollow plants, with their epidermis of silex, should arise in soils that are not silicious? being equally predominant, whether the soil be calcareous, argillaceous, or loamy. The decomposition of decayed animal and vegetable substances, doubtless composes the richegt superficial mould; but this ...
