Over all this, we can behold the move- ments of moisture—rising from the Atlantic, to be borne and diffused over Europe, South America as far as the Andes, and North America as far as the Rockies; from the Pacific to be almost entirely con- densed by the adjacent mountains of America, Aus- tralia, and Asia and deposited in abundance along the intervening coasts and plains; and, finally, from the Indian Ocean, to water the river basins and coasts of Southern Asia as well as eastern and equatorial Africa. Such movements of moisture are effected by corresponding movements of the atmos- phere, that overspreads the surface already con- sidered ; with its gaseous elements continually maintained in motion by changing temperatures— expanding and ascending at the equator towards the upper layers that move obliquely towards the tropics, mingling there with cold polar winds arriving from exactly opposite directions, and again descending in these regions of calms from which the Trade Winds blow obliquely, inwards towards the equator and outwards towards the poles. Beneath these atmospheric vapours and gases, and diffused over the face of our picture, are the living forms— vegetable, animal, and human—already described. As regards vegetable life, we see again the varieties
