The building up of the Grand Canary by subaerial eruptions, several thousand feet thick, went on simultaneously with the gradual upheaval of the earliest products of submarine eruptions, in the same manner as the Pliocene marine strata of the oldest parts of Vesuvius and Etna have been upraised during eruptions of Post-tertiary date.
No doubt he was in mind back again in his Johannæum, holding forth to his pupils, for he assumed his learned air; and addressing himself to an imaginary audience, he proceeded thus: "Gentlemen, I have the honour to introduce to you a man of the quaternary or post-tertiary system. Eminent geologists have denied his existence, others no less eminent have affirmed it. The St.
Had there been strong prepossessions against the progressive theory, it would probably have been argued that when these cephalopods abounded, and the siphonated gasteropods were absent, a higher order of zoophagous mollusca discharged the functions afterwards performed by an inferior order in the Secondary, Tertiary, and Post-Tertiary seas.
New Zealand has no indigenous mammalia, but in their place great cursorial birds with but rudimentary wings. Exactly the same thing is found by geology in its tertiary and post-tertiary strata: nowhere a mammal, but gigantic birds with rudimentary wings, down to the dinornis, which probably died out in man's time.
Great upheaving movements have been experienced in the region of the Andes, during the Post-tertiary period. In some part, therefore, of this chain, we may expect to discover tertiary Plutonic rocks laid open to view; and Mr.
What an all-absorbing post-tertiary deposit for future generations, for the crafty antiquarian who deciphers the history of mankind out of kitchen-middens and deformed heaps of forgotten trash! The whole social life of the citizens, their arts, domestic economy, and pastimes, lies embedded in that rubbish.
But it is probable that the multiplication of such movements in the post-Tertiary period has rarely been so great as to produce results like those above described in Moen, for the principal movements in any given period seem to be of a more uniform kind, by which the topography of limited districts and the position of the strata are not visibly altered except in their height relatively to the sea.
On the opposite or western coast of Sweden, at Uddevalla, Post-Tertiary strata, containing recent shells, not of that brackish water character peculiar to the Baltic, but such as now live in the Northern Ocean, ascend to the height of 200 feet; and beds of clay and sand of the same age attain elevations of 300 and even 600 feet in Norway, where they have been usually described as "raised beaches."
These gentlemen concerned in the enterprise will, of course, lose their money, and I shall therefore decline to accept the very handsome fee which they had offered me for my services. But the main feature, the real point of interest in this matter remains. Here we have undoubtedly a sporadic deposit what miners call a pocket of pure gold in a Devonian formation of the post-tertiary period.
On this Sunday morning he offered a simple evangelical discourse, enhanced by those occasional references to palæozoic and post-tertiary periods which were expected from him, and which he had enough of the wisdom of the serpent to supply.
