Стр. 244 - I know of no other peak that impresses the mind so deeply with the sense of wonder and awe. As seen from the north the eastern and western faces are almost equally precipitous, and the broad top is jagged by sharp teeth, of which the two outermost, one to the east, the other to the west, present summits of apparently equal height. At a distance of about twenty-five miles the whole mass seemed to be coated with snow and ice, save where some sharp ridges and teeth of black rock stood out against the...
Стр. 245 - ... may be of igneous origin, Sarmiento is certainly not a volcanic cone, nor is even the rock of which it is composed of plutonic origin. " Whether its real form be that of a tower, or that of a ridge with precipitous sides seen in profile, no volcanic rocks elsewhere in the world can retain slopes so nearly approaching to the vertical. It is, I believe, a portion of the original rock skeleton that formed the axis of the Andean chain during the long ages that * Popper, Boletin del Iiwtituto Geogrdfico...

Стр. 274 - The general conclusion, which seems to be fully established, is that the southern hemisphere is not colder than the northern, and that all arguments based upon an opposite assumption must be set aside.

Стр. 129 - Not only was there no green thing; not even a speck of lichen could I detect, though I looked at the rocks through a lens. Even more than by the absence of life, I was impressed by the appearance of the surface, which showed no token that water had ever flowed over it. Every edge of rock was sharp, as if freshly broken, and on the steep slope no trace of a channel furrowed its face.* The aspect is absolutely that of the scenery of the moon—of a world without water and without an atmosphere.
Стр. 365 - ... no one could be in his company without feeling its subtle influence. On one occasion a periodical was lent to him containing an article wherein the writer, with apparent gravity, discussed the question ' Whether life was worth living.' It caused him to place on record the 'contemptuous pity he felt for the man whose mind could be so profoundly diseased as even to ask such a question — as if a soldier with the trumpet call sounding in his ear, should stop to inquire whether the battle was worth...
Стр. 299 - E.), and does not exceed that of Cairo and Lower Egypt. The difference between the mean temperature of the hottest and coldest months, rises to 12° in the interior of the island ; at the Havannah, and on the coast, to 8° ; at Cumana, to scarcely 3°. The hottest months, July and August, attain 28'8°, at the island of Cuba, perhaps 29-5° of mean temperature, as at the equator.
Стр. 165 - ... (Erodium cicutarium), which has made itself equally at home in the upper zone of the Peruvian Andes, in the low country of central Chili, and in the plains of north Patagonia.
