One system, now called the Plutonian, regards, the earth's crust on which we now live, as the debris of two former worlds, and our present continents as the elevations of the bottom of the sea by subterranean heat. If this theory be founded on fact, why do not our rocks present us with beds of shell-fish in families as are now living at the bottom of the sea?
