"Geologically" Quotes from Famous Books
 ... current, like the Gulf Stream, equal in volume to many hundred Mississippis, and having in parts a surface velocity of more than three miles, may act as a propelling and abrading power at still greater depths. But the efficacy of the sea as a denuding agent, geologically considered, is not dependent on the power of currents to preserve at great depths a velocity sufficient to remove sand and mud, because, even where the deposition or removal of sediment is not in progress, the ...

... sea shells, the tides must have risen and fallen twice every day, as they now rise and fall along the beach that at present girdles our country. But, in reference to at least human history, the age of the old coast-line and terrace must be a very remote one. Though geologically recent, it lies far beyond the reach of any written record. It has been shown by Mr. Smith of Jordanhill, one of our highest authorities on the subject, that the wall of Antoninus, erected by the Romans as a protection against the Northern Caledonians, was made to terminate at the ...

... should never be forgotten, namely, that very many fossil species are known and named from single and often broken specimens, or from a few specimens collected on some one spot. Only a small portion of the surface of the earth has been geologically explored, and no part with sufficient care, as the important discoveries made every year in Europe prove. No organism wholly soft can be preserved. Shells and bones decay and disappear when left on the bottom of the sea, where ...

... of which we had heard much from stockmen as likely to trouble us because, as they said, its rocky extremities overhung the creek. We crossed it with ease however, guided by the native. It consisted of granite and evidently belonged geologically to the ridge traversed by us on the second day after leaving Buree during our last journey. On the range, green pine trees (callitris) and a luxuriant crop of grass covering the adjacent country, multitudes ...

... building. The same tradition applied to the Round Tower of Abernethy, in Perthshire, only it is in this case demonstrated that the stone of which the tower is composed was actually taken from the traditional quarry, even the very spot being geologically identified.[16] In like manner, too, was Rama's bridge built by the monkey host in Hindu myth, as recounted in the Mah[a]bh[a]rata ...

... roll the contents of a suspicious bottle (in very small quantities) doubtfully upon the tongue in order to discover whether it is pale sherry or Chili vinegar, Dublin stout or mushroom ketchup. But in the savage state, from which, geologically and biologically speaking, we have only just emerged, bottles and labels do not exist. Primitive man, therefore, in his sweet simplicity, has only two modes open before him for deciding whether the things ...

... each on the plan of the pre-existing ones. St. Helena is a similar case of a very ancient island having obtained an entirely peculiar, though limited, flora. On the other hand, no example is known of an island which can be proved geologically to be of very recent origin (late in the Tertiary, for instance), and yet possesses generic or family groups, or even many species ...

... said the Archipelago belongs to Asia — geologically, zoologically, and botanically — rather than to Oceania, and that, apparently, the entire Archipelago has shared a common origin and existence. There is evidence that it was connected with the mainland by solid earth in the early or Middle Tertiary. For a long geologic ...

... were collected by Mr. George Gardner, to whom science is indebted for the most extensive information yet obtained respecting the geology of that part of Brazil. In this connection, let me say that here and elsewhere I shall speak of the provinces of Ceara, Piauhy, and Maranham as belonging geologically to the Valley of the Amazons, though their shore is bathed by the ocean, and their rivers empty directly into the Atlantic. But I entertain no doubt, and I hope I may hereafter be able to show, that, at an earlier period, ...

... inner portion of Southern Africa is, in this respect, as far as I know, geologically unique in the long conservation of ancient terrestrial conditions. This inference is further supported by the concomitant absence, throughout the larger portion of all this vast area, i.e. south of the Equator, of any of those volcanic rocks which are ...
