Strana xxxviii - GEOLOGY is the science which investigates the successive changes that have taken place in the organic and inorganic kingdoms of nature; it inquires into the causes of these changes, and the influence which they have exerted in modifying the surface and external structure of our planet.
Strana iv - A work conspicuous for attractiveness, for perspicuity, for a style generally vigorous and correct— often elegant and beautiful, and for an independence of spirit which carries the author straight forward to his object without any servile regards to previous systems. Mr. Bakewell's work has long been our favourite elementary treatise on Geology."— ATHENAEUM.
Strana 441 - ... began to give way, and the greatest part of it actually fell in and disappeared in the earth. At the same time a tremendous noise was heard, resembling the discharge of the heaviest cannon. Immense quantities of volcanic substances, which were thrown out at the same time and spread in every direction, propagated the effects of the explosion through the space of many miles.
Strana 417 - the violent paroxysm of the earthquake ceasing, I stood up, and, turning my eyes to look for Euphemia, saw only a frightful black cloud. We waited till it had passed away, when nothing but a dismal and putrid lake was to be seen where the city once stood.
Strana 601 - ... little better than a moral sepulchre, in which, like the strong man, we were burying ourselves and those around us in ruins of our own creating. But surely we must all believe too firmly in the immutable attributes of that Being, in whom all truth, of whatever kind, finds its proper resting-place, to think that the principles of physical and moral truth can ever be in lasting collision.
Strana 222 - MP the mountain which is here composed of clinkstone, presents the columnar structure on a magnificent scale ; the columns are slightly bent and inclined. Porphyry, from an intermixture with hornblende frequently passes into sienite ; when this is the case, the latter rock generally forms the upper part of the mass. Porphyry and basalt, in enormous masses, often cover the primary mountains in the Andes. According to Humboldt, " they are arranged in regular columns, which strike the eye of the traveller...
Strana 323 - The gigantic Megalosaurus, and yet more gigantic Iguanodon, to whom the groves of palms and arborescent ferns would be mere beds of reeds, must have been of such prodigious magnitude, that the existing animal creation presents us with no fit objects of comparison. Imagine...
Strana 181 - London in the year 1308, by the royal proclamation of Edward the First. In the reign of Queen Elizabeth, the burning of coal was again prohibited in London during the sitting of parliament, lest the health of the knights of the shire should suffer injury during their abode in the metropolis. In...
Strana 423 - ... every moveable which the earthquake had not buried under heaps of ruins was carried out to sea. In a few minutes, the vessels were again aground, and a second great wave was seen approaching, with more noise and impetuosity than the first...
Strana 441 - Immense quantities of volcanic substances, which were thrown out at the same time and spread in every direction, propagated the effects of the explosion through the space of many miles. " It is estimated that an extent of ground, of the mountain itself and its immediate environs, fifteen miles long and full six broad, was by this commotion swallowed up in the bowels of the earth.
