In the course of ages much of the earth's heat was radiated into space; and this went on till at length the earth became sufficiently cooled for some portion of it to assume a solid state. It was probably in this manner that the first hard rock-masses made their appearance on the earth's surface. As the cooling continued, the water-vapour, or steam, which must have been present in the hot atmosphere, became condensed into the liquid state ; the water itself was then subjected to the cooling influence of radiation, and in course of time the earth's surface became inhabited by low forms of life. The effect of the sun's heat in those far-distant ages would be then, as now, to cause the water on the earth's surface to rise up in the form of vajmur, and so to form clouds. These clouds, floating about in the higher regions of the atmosphere, would become sufliciontly cooled for their water-vapour to be condensed and fal
