"Silurian" Quotes from Famous Books
 ... 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, ...

... beds of peat; but the remains of plant-tissue are contained in all the older formations, though there only as anthracite or graphite—the last two groups of residual products. Of these we have examples in the beds of graphite in the Laurentian rocks of Canada, and of anthracite of the lower Silurian strata of Upper Church ...

... first form which existed of each of the great divisions would present points intermediate between existing ones, but immensely different. Most geologists believe Silurian{117} fossils are those which first existed in the whole world, not those which have chanced to be the oldest not destroyed,—or the first which existed in profoundly deep seas in progress of conversion from sea to land: if they are first they give up. Not so Hutton or Lyell: ...

... 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 that have since existed and are ...

... our Royal Geographical Society has borne the most important part, and none of its members have done more than my highly-gifted friend the President, Sir Roderick Murchison, geologist of Russia, and founder and author of the colossal "Silurian System." To the affection of this friend, sanctioned by the unanimous approval of the council of that illustrious Society, I owe the honour of being awarded the Victoria Medal for my "Physical Geography." An honour so unexpected, and so far ...

... Cancellaridae. It is certainly entirely distinct in every respect from any known Gasteropod. It is a form of very great interest to the geologist, for in it we see the nearest representation of certain palaeozoic (especially Lower Silurian) univalves hitherto referred to Littorina, but which, judging from their associates and the indications afforded by the strata in which they are found, were assuredly either inhabitants of deep water or floaters in a ...

... seen that fishes, which are the oldest vertebrates, first appear in the Silurian strata, and are found in all the succeeding formations up to the birds of the Tertiary Period. Reptiles begin in like manner in the magnesian limestone, and if we now add that the first mammalia are met with in Oolite, the Stonefield slate; and that the first remains of birds have been ...

... despite of piles and pier and wharf, the Pacific tides still asserted themselves in mud and ooze as far as Sansome Street; the wooden sidewalks of Clay and Montgomery streets were mere floating bridges or buoyant pontoons superposed on elastic bogs; Battery Street was the Silurian beach of that early period on which tin cans, packing-boxes, freight, household furniture, and even the runaway crews of deserted ships had been cast away. There were dangerous and unknown depths in Montgomery Street and on the Plaza, and the wheels of a passing carriage hopelessly mired had ...

... conclusions, such as his "Colonies" (41/3. Lyell briefly refers to Barrande's Bohemian work in a letter (August 31st, 1856) to Fleming ("Life of Sir Charles Lyell," II., page 225): "He explained to me on the spot his remarkable discovery of a 'colony' of Upper Silurian fossils, 3,400 feet deep, in the midst of the Lower Silurian group. This has made a great noise, but I think I can explain away the supposed anomaly by, etc." (See Letter 40, Note.) and his agreement with E. de Beaumont's lines of ...

... the paper with linen threads, my dear. A very delicate performance; that's why Linen Wove is so expensive. Azure Wove is, of course, done with blue flaxen threads. Silurian Bond is made by a fellowship of geologists, and for Chelsea Bank they have a factory on the bank of the Thames at Cheyne Walk. That's all I need tell you, though I ...

... years old,' as reported home by a scientific official on the spot. The 'coffins,' or abandoned native diggings, must date from at least two centuries ago. The natives scraped off the gold-bearing stone till the water drove them out. The formation is upper Silurian or lower Devonian, a transition to gneiss, but not highly metamorphic. No fossils have yet been found: if any exist they would be microscopic. Where talcose it is bluish, and shows streaks of 'black sand,' titaniferous iron. The grey sand washes to white. There are pot-holes which ...

... members of his marital stud for discussion of their points with his more humble fellow-polygamist of the hammer; but when I happened to touch upon the earliest Mrs. Heber, whom I naturally thought he would by this time regard as a forgotten fossil in the Lower Silurian strata of his connubial life, and referred to the interview I had enjoyed with her on the afternoon before entering the city, his whole manner changed to a proper husbandly dignity, and, without seeking corroboration from the carpenter, ...

... life, and to which he himself attached the greatest importance. In Wales he took up the question of the age of the rocks in the neighbourhood of Dolgelly, and after much study of their fossils proposed the now accepted classification of the Lingula flags of the Lower Silurian system into the Maenturog flags and slates, the Festiniog flags, and the Dolgelly slates. The collecting of lepidoptera was his chief amusement in Brazil, where he made his first acquaintance with the teeming life of the torrid ...
