Page 176 - Microdiscus with four, to Erinnys with twenty-four, and blind genera along with those having the largest eyes, leads to the conclusion that for these several stages to have taken place numerous previous faunas must have had an existence, and, moreover, that even at this time in the history of our globe an enormous period had elapsed since life first dawned upon it.
Page xx - To promote researches concerning the mineral structure of the earth, and to enable the Council of the Geological Society to reward those individuals of any country by whom such researches may hereafter be made,' — ( such individual not being a Member of the Council.
Page xxviii - The Wollaston Fund has been awarded to Mr. James Croll, of Edinburgh, for his many valuable researches on the glacial phenomena of Scotland, and to aid in the prosecution of the same. Mr. Croll is also well known to all of us by his investigation of oceanic currents and their bearings on geological questions, and of many questions of great theoretical interest connected with some of the great problems in Geology. Will you, Prof.
Page 361 - Tanio;ifens-epochs, which by some had been regarded the one as Palaeozoic and the other as Mesozoic, he was not convinced that they could be distinctly separated, but thought rather that they might both belong to different portions of one great period. Systematically the two forms might be very closely related, the venation of the fronds on which the genera are founded occurring in two forms, which by Linnaeus had been included in one genus, Acrostichum.

Page 89 - ... exposures of the stratified beds. This singular deposit varies in thickness from a few inches to two or three feet, and is taken advantage of by the Moors for the excavation of cellars in the soft ground, over which the crust forms a strong roof.
Page 398 - ... the stratum, for the purpose of making superphosphate of lime. Two hundred and seventy tons per acre, at the rate of fifty shillings a ton, represents the valuable yield of the deposit, which is followed to the depth of about 18 feet. The nodules and other fossils of the bed are chiefly derivative, forming a concentrated accumulation from a deposit belonging to the Lower Cretaceous period. Some of the fossils, however, are believed to be indigenous to the deposit.
Page xcii - Nordenskjb'ld regards them as aerolites, and accounts for their occurrence in the basalt by supposing that they proceeded from a shower of meteorites which had fallen down and buried themselves in the molten basalt during an eruption in the Miocene period. Notwithstanding that these masses of metallic iron were found lying on the shore between the ebb and flow of tide, it has been found, upon their removal to Stockholm, that they perish with extraordinary rapidity, breaking up rapidly and falling...

In the northern part countless herds of Reindeer, Elks, Foxes, and Wolverines make up for the poverty of vegetation by the rich abundance of animal...

Several of these specimens have been submitted to chemical analysis, which proved them to contain nearly 5 per cent, of nickel, with from...
