"Silurian" Quotes from Famous Books
... Siberia, ch. 17, gold is to be found only "in crystalline and paleozoic rocks, or in the drift from these rocks, which is a tertiary accumulation of the pliocene age;" and that it is found most abundantly "in quartz-ore, vein-stones and traverse altered Silurian slates, chiefly lower Silurian, frequently near their junction ... — Principles Of Political Economy • William Roscher
... time and space to describe some of the beautiful bacteria and gigantic worms that formerly inhabited the earth. Such an aggregation of actual, living Silurian monsters, any one of which would make a man a fortune to-day, if it could be kept on ice and exhibited for one season only. You could take a full grown mastodon to-day, and with no calliope, no lithographs, no bearded lady, ... — Remarks • Bill Nye
... Satpura range, thus defined, separates the valley of the Nerbudda from the valleys of the Tapti flowing west, and the Mahanadi flowing east. The Vindhyan sandstones certainly are a formation of immense antiquity, perhaps pre-Silurian. They are azoic, or devoid of fossils; and it is consequently impossible to determine exactly their geological age, or 'horizon' (ibid. p. xxiii). The cappings of basalt, in some cases with laterite superimposed, suggest many difficult ... — Rambles and Recollections of an Indian Official • William Sleeman
... of the same kind may be found in every sub-kingdom. The 'Globigerina' of the Atlantic soundings is identical with that which occurs in the chalk; and the casts of lower silurian 'Foraminifera', which Ehrenberg has recently described, seem to indicate the existence at that remote period of forms singularly like those which now exist. Among the corals, the palaeozoic 'Tabulata' are constructed on precisely the same type as the modern millepores; and if we turn to molluscs, ... — Time and Life • Thomas H. Huxley
... most prominent in modern geological periods, those that existed were expressed in such endless variety that the Animal Kingdom seems to have been as full then as it is to-day. The Class of the Echinoderms is one of the most remarkable instances of this. In the Silurian period, the Crinoids stood alone; there were neither Ophiurans, Asteroids, Echinoids, nor Holothurians; and yet in one single locality, Lockport, in the State of New York, over an area of not more than a few square miles, where the Silurian deposits ... — Atlantic Monthly, Vol. 10, No. 57, July, 1862 - A Magazine Of Literature, Art, And Politics • Various
... a place called absurdly enough Paris, from the quantity of gypsum with which the neighbourhood abounds; and fine specimens of silurian fossils of the trilobite family and of madrepores, millepores, and corallics, are found here. Love's Hotel is the best in the village, and a ... — Canada and the Canadians, Vol. 2 • Richard Henry Bonnycastle
... men skinned and galvanized, not men alive and in action. In the same way in landscape, do you think Turner would have painted the strata in an old quarry, or done Ben Cruachan more to the quick, had he known all about geology, gneiss, and graywacke, and the Silurian system? Turner might have been what is called a better-informed man, but we question if he would have been so good, not to say a better representer of the wonderful works of God, which were painted on his retina, and in his inner chamber—the true Camera ... — Spare Hours • John Brown
... the name applied to series of stratified fossiliferous and igneous rocks that were formed during the Devonian period, that is, in the interval of time between the close of the Silurian period and the beginning of the Carboniferous; it includes the marine Devonian and an estuarine Old Red Sandstone series of strata. The name "Devonian" was introduced in 1829 by Sir R. Murchison and A. Sedgwick to describe the older rocks of Cornwall and Devon ... — Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 3 - "Destructors" to "Diameter" • Various
... boreal and arctic latitudes into North America. Of the height and mass of this primeval land some idea may be formed by considering the enormous bulk of the material derived from its disintegration. In the Silurian formations of the British Islands alone there is a mass of rock, worn from the land, which would form a mountain-chain extending from Marseilles to the North Cape (1800 miles), with a mean breadth of over thirty-three miles, and an average height ... — The Antediluvian World • Ignatius Donnelly
... thing may be said of other organic divisions. It has gone to record that the shell-fish of the Silurian system are the lowest division of the molluscous animals. While the statement is received as true, it must be remembered that there is some diversity of structure in this lower division, and that the earliest molluscs are not the lowest, but the highest in the division. The most important ... — The Christian Foundation, Or, Scientific and Religious Journal, Volume I, No. 7, July, 1880 • Various
... a good sort in some ways, but a very ignorant man. I showed him some of my specimens the other day, and he thought them granitic, when they were really Silurian mica schist of some kind," put in Mrs. Sykes, who never could bear unqualified praise. "Still, on the whole, the Americans are less ignorant ... — Lippincott's Magazine, August, 1885 • Various
... discovered that the "greensands" of the geologist were largely made up of casts of a similar character, and proved the existence of Foraminifera at a very ancient geological epoch, by discovering such casts in a greensand of Lower Silurian age, which occurs ... — Discourses - Biological and Geological Essays • Thomas H. Huxley
... strongly suggest the evolution of the human no less than the lower animal races out of some simple primordial animal,—that all are equally "lineal descendants of sense few beings which lived long before the first bed of the Silurian system was deposited." But, as the author speaks disrespectfully of spontaneous generation, and accepts a supernatural beginning of life on earth, in some form or forms of being which included potentially all ... — Atlantic Monthly Vol. 6, No. 33, July, 1860 • Various
... if you will get the thought into your mind that our present penal system is Silurian and unscientific—the same to-day as it was 10,000 years ago—you will see my stand-point. Our penitentiaries develop criminals, they make criminals out of men who are not criminals to begin with—boys, for instance. They debase and degrade men. ... — The Letters of Franklin K.
