Seite 536 - PORTLOCK.- REPORT ON THE GEOLOGY OF THE COUNTY of LONDONDERRY, and of Parts of Tyrone and Fermanagh, examined and described under the Authority of the Master-General and Board of Ordnance. By JE PORTLOCK, FRS &c.
Seite 374 - These conclude the first part of the book : the second part is devoted to
Seite 386 - The very small head and brain, and slender neural cord, indicate a stupid, slow moving reptile. The beast was wholly without offensive or defensive weapons, or dermal armature. In habits, Brontosaurus was more or less amphibious, and its food was probably aquatic plants or other succulent vegetation. The remains are usually found in localities where the animals had evidently become mired.
Seite 142 - He contributed to the excellent guide which was published under the sanction of the local executive committee of the British Association...
Seite 397 - While it is probable that some definite peculiarities are at the basis of the differences in the geographical distribution of cancer, they have so far not been discovered. I do not propose here to discuss the many theories which have been advanced from time to time to account for the origin of cancer, none of which affords a satisfactory explanation of the nature of malignant disease. The fact, however, that we are up to the present ignorant of its actual cause does not prevent our attacking the...
Seite 326 - The object of the author was to prove that the eastern gneiss of the Northern Highlands, usually regarded as of " Lower Silurian " age, was to be placed in the Archaean. While admitting that this gneiss frequently overlies the quartzodolomitic group of Erriboll and Assynt, he held that this relation was due to dislocation accompanied by powerful thrust from the east, which had squeezed both formations into a series of folds, thro*n over towards the west, so as to cause a general easterly dip. In...
Seite 75 - On this hypothesis, the submergence of Wales to the extent of 1,400 feet, would, at this rate, require 56,000 years, " but taking " Prof. Ramsay's estimate of 800 feet more, that elevation being " required for the deposition of some of the stratified drift, we must " demand an additional period of 32,000 years, amounting in all to " 88,000 ; and the same time would be required for the re-elevation " of the tract to its present height.
Seite 283 - ... Bagshot. The Upper Bagshot Sands were then described, and attention was drawn to the abundance of fossils in some of the higher beds. The author then referred to the correlation of the Bagshot beds with the Hampshire series, and stated his conclusion that the Middle Bagshot beds are of Middle...
Seite 248 - When there has been no reason to suppose that the trawl has sunk more than one or two inches in the clay, we have had in the bag over a hundred sharks...
Seite 303 - No, certainly. She will heel over to larboard. Many a good ship has gone to the bottom in this way. If the continents be lightened, they will rise ; if the bed of the sea receive additional weight, it will sink. The bottom of the Pacific is sinking, in point of fact. Not that the Pacific is becoming deeper. This seems a paradox ; but it is easily explained. The whole bed of the sea is in the act of being pressed down by the laying on of...
