Página 79 - ... we find at New York, the summer of Rome, and the winter of Copenhagen ; at Quebec, the summer of Paris, and the winter of St Petersburgh. At Pekin, also, where the mean temperature of the year is that of the coasts of Brittany, the scorching heats of summer are greater than at Cairo, and the winters are as rigorous as at Upsal.
Página 381 - Very great numbers of birds, wild animals, cattle, and horses perished from the want of food and water. A man told me that the deer* used to come into his courtyard to the well, which he had been obliged to dig to supply his own family with water; and that the partridges had hardly strength to fly away when pursued.
Página 381 - Subsequently to the drought of 1827 to 1832, a very rainy season followed, which caused great floods. Hence it is almost certain that some thousands of the skeletons were buried by the deposits of the very next year. What would be the opinion of a geologist viewing such an enormous collection of bones, of all kinds of animals and of all ages, thus embedded in one thick earthy mass? Would he not attribute it to a flood having swept V over the surface of the land, rather than to the common order of...
Página 381 - I was informed by an eye-witness that the cattle in herds of thousands rushed into the Parana, and being exhausted by hunger they were unable to crawl up the muddy banks, and thus were drowned. The arm of the river which runs by San Pedro was so full of putrid carcasses, that the master of a vessel told me that the smell rendered it quite impassable. Without doubt several hundred thousand animals thus perished in the river: their bodies when putrid were seen floating down the stream; and many in...
Página 327 - Polar light, nothing more is thereby implied than the local direction in which the beginning of a certain luminous phenomenon is most generally, but by no means invariably, seen. What gives this phenomenon its greatest importance, is the fact which it reveals, viz., that the earth is luminous ; that our planet, besides the light which it receives from the central body, the sun, shews itself capable of a proper luminous act or process.

Página 228 - ... becomes so soft and pliant as to be capable of being moulded into any form, or of being rolled out into long pieces or flat plates. "When in the soft state, it possesses all the elasticity of common India-rubber, but it does not retain these properties long. It soon begins again to grow hard, and a short time, varying according to the temperature and the size of the piece operated on, regains all its original hardness and rigidity.
Página 379 - One of the men had already found thirteen deer (Cerna campestris) lying dead, and I saw their fresh hides. Another of the party, a few minutes after my arrival, brought in seven more. Now, I well know that one man without dogs could hardly have killed seven deer in a week. The men believed they had seen about fifteen dead ostriches (part of one...
Página 221 - This illustration is certainly very unhappy ; for, rejecting the pretended antiquity of the Chinese — the fables in relation to Fohi and Hoang-Ti, the former of whom, we are told, founded the empire of China about five thousand years ago, we must, with Malte-Brun, date its origin at least eight or nine centuries before Christ. China should, therefore, possess a milder climate than Europe, inasmuch as agriculture is represented to have been always in the most flourishing condition. As the practice...
