Página 240 - The vapor is taken from the surface water; the surface water thereby becomes more salt, and, under certain conditions, heavier ; when it becomes heavier, it sinks ; and hence we have, due to the salts of the sea, a vertical circulation, namely, a descent of heavier — because salter and cooler — water from the surface, and an ascent of water that is lighter — because it is not so salt — from the depths below.

Página 164 - Moseley replied as follows : — " To this there is the obvious answer that radiant heat does find its way into ice as a matter of common observation, and that it does not melt it except at its surface. Blocks of ice may be seen in the windows of iceshops with the sun shining full upon them, and melting nowhere but on their surfaces. And the experiment of the icelens shows that heat may stream through ice in abundance (of • Phil. Hag., S. 4, vol. x., p. 303. t Proceedings of the Bristol Naturalists'...
