"Quaternary" Quotes from Famous Books



... march there was much of what at a hasty glance seemed to be volcanic rock; but Oliveira showed me that it was a kind of conglomerate, with bubbles or hollows in it, made of sand and iron- bearing earth. He said it was a superficial quaternary deposit formed by erosion from the cretaceous rocks, and that there were here no tertiary deposits. He described the geological structure of the lands through which we had passed as follows: The pantanals were of Pleistocene age. Along the upper Sepotuba, in the region of the rapids, ...

... as have been published it appears that the rock formations of Santo Domingo correspond to the secondary, the lower and middle tertiary and the quaternary epoch. The most ancient part of the island is the central mountain range, also a series of protuberances in the Samana peninsula, the nucleus of the Baboruco mountains and a single point in the northern coast range ...

... scale the world's melodies have been sounded, nor do any doubt that our successors will thrill to airs that we have never heard. "Thirty metals may be combined into 435 binary alloys, 4,060 ternary alloys, 27,405 quaternary alloys" (Jevons). This does not take into consideration differences in proportion that figure so largely in results in the arts of substance-making. The total number of possible alloys of the known metals ...

... in the ten; for all people, whether Grecians or barbarians, reckon from one to ten, and thence return to one again. Farther he avers the virtue of ten consists in the quaternion; the reason whereof is this,—if any person start from one, and add numbers so as to take in the quaternary, he shall complete the number ten; if he passes the four, he shall go beyond the ten; for one, two, three, and four being added up together make ten. The nature of numbers, therefore, if we regard the units, abideth in the ten; but if we regard ...

... belongs to that which is known as the "quaternary" formation. Here no rocks like those mentioned above are found; indeed, rocks, in the ordinary sense of that term, are unknown.

... present time but very little has been known of the existence of the peculiarly American family Procyonidae in any deposits older than the very latest Quaternary. Leidy has described and figured[1] an isolated last upper tooth, from the Loup Fork deposits of Nebraska, under the name of Leptarctus primus, which has been referred to this family. The Museum Expedition of last year into this region was successful ...

... discover the remains of our less specialised primatic ancestors in the strata which have yielded the less specialised equine and canine quadrupeds. At present, fossil remains of men do not take us hack further than the later part of the Quaternary epoch; and, as was to be expected, they do not differ more from existing men, than Quaternary horses differ from existing horses. Still earlier we find traces of man, in implements, such as are used by the ruder savages at the present day. Later, the remains ...

... obstinate opponent in M. Elie de Beaumont. This high authority maintained that the soil of Moulin Quignon was not diluvial at all, but was of much more recent formation; and, agreeing in that with Cuvier, he refused to admit that the human species could be contemporary with the animals of the quaternary period. My uncle Liedenbrock, along with the great body of the geologists, had maintained his ground, disputed, and argued, until M. Elie de Beaumont stood almost alone in ...

... impression is at the bottom of all our ideas, all our conceptions, though it may at first conceal itself in the form of a binary, ternary, quaternary compound; and, on our methodically pursuing the inquiry, it is easily recognizable—just as a simple substance in organic chemistry may be always summoned to appear, if we sit down with the resolution to disengage it from all the artificial combinations which ...

The subtle wanderings of Neoplatonism were continued obscurely in the school of Athens until it was closed for ever in 529 by the Emperor ...
