Strana 473 - aurora borealis, reflected by the snow, dispels the darkness of the polar night. The days for several months, though of a monotonous magnificence, astonishingly accelerate the growth of vegetation. In three days, or rather three times twenty-four hours, the snow is melted, and the flowers begin to blow.
Strana 185 - greater number of the principal mountains have one of their sides very steep, and the other of a very " gradual slope.* The Alps, for example, are much more rapid in their descent on the Italian side than on that of Switzerland. On the contrary, the Dophrines, or Scandinavian Alps, have a much steeper declivity to the

Strana 361 - a blue shade to distant mountains, and which give the atmosphere its azure hue. The rays of blue light, being the most refrangible, pass in the greatest quantity through the aquatic fluid, which, from its density and depth, makes them undergo a strong refraction. The other shades in the
Strana 472 - the proximity of very high mountains, covered with perpetual snow; the trade winds, and the periodical inundations, equally contribute to diminish the heat. This is the reason why, in the torrid zone, we meet with all kinds of climates. The plains are burnt up by the heat of the sun. All the eastern coasts of the great continents,
Strana 357 - true surface of our planet The only exception to this position, may perhaps be found in gulfs and inland seas, which have only a slight communication with the ocean. In these parts of the sea. the level of the water may sometimes be a little more elevated than in the ocean. It is alleged that the Dutch
Strana 24 - of the ecliptic causes the arc of the equator, which passes the meridian in the same time with the diurnal arc of the ecliptic, to be not always equal to it, but to be sometimes greater and sometimes less. With regard to the
