Сторінка 179 - Tuscorora" and "Challenger" have made known numerous submarine elevations : mountains rising from the general level of the ocean's bed, at a depth of 2500 or 3000 fathoms, up to within a few hundred fathoms of the surface.
Сторінка 168 - October 2, 1879, expresses his continued adherence to the opinion "that the atolls and barrier reefs in the middle of the Pacific and Indian Oceans indicate subsidence" ; and the letter of my friend Professor Judd, printed at the end of this article (which I had perhaps better say Professor Judd had not seen) will prove that this opinion remained unaltered to the end of his life.
Сторінка 188 - ... mountain-peak basement for the structure. The subsidence which the Darwinian theory requires has not been opposed by the mention of any fact at variance with it, nor by setting aside Darwin's arguments in its favour; and it has found new support in the facts from the "Challenger's...
Сторінка 261 - ... we may not merely admit, but assert as highly probable, that the axis of maximum inertia and the axis of rotation, always very near one another, may have been in ancient times very far from their present geographical position and may have gradually shifted through ten, twenty, thirty, or forty or more degrees without at any time any perceptible sudden disturbance of either land or water."1 Mr.
Сторінка 169 - ... by a personal injury, any attempt to show that it can no longer claim the general applicability which has been regarded as one of the strongest arguments in its favour. But the example of Darwin's own candour and over-mastering love of truth remains to assure us that no one would have welcomed fresh discoveries more heartily than he, even should they lead to the setting aside of some of his own work.
Сторінка 169 - Toiigatabu, in the Friendly group ; two, Taputeaua and Apia, in the Gilbert group, and five others near the equator, east of the Gilbert group ; Swain's Fakaofu, Oatafu, Hull and Enderbury Island, as well as the reef region of the Sooloo Sea and of the Straits of Malacca.
Сторінка 248 - The liquidity of our globe, and the relative thinness of its encrusted envelope — as attested by all legitimate geological induction — will be assumed without misgiving or hesitancy, and the supposed matematical arguments for its solidity ignored as essentially fallacious and wholly inconclusive.
Сторінка 172 - ... (4.) That barrier reefs have built out from the shore on a foundation of volcanic debris or on a talus of coral blocks, coral sediment, and Pelagic shells, and the lagoon channel is formed in the same way as a lagoon. (5.) That it is not necessary to call in subsidence to explain any of the characteristic features of barrier reefs or atolls, and that all these features would exist alike in areas of slow elevation, of rest, or of slow subsidence. In conclusion it was pointed out that all the causes...
Сторінка 253 - ... together. Signs of the existence of an atmosphere are observed on the Sun, on Venus, Mars, Jupiter, and Saturn. Signs of water and ice upon Mars; and our earth has undoubtedly a fluid portion on its surface, and perhaps a still greater portion of fluid within it. The motions of the tides, however, produce friction, all friction destroys vis viva, and the loss in this case can only affect the vis viva of the planetary system. We come thereby to the unavoidable conclusion, that every tide, although...
Сторінка 168 - He appears to have examined one atoll, the Keeling Beef, and one barrier-reef, that of Tahiti." " By a gradually widening circle of observations a series of facts has been established which were either not known, or only partially known, to Darwin.
