Have the changes which lead us from one geological state to another been, on a lang average, uniform in their intensity, or have they consisted of epochs of paroxysmal and catastrophic action, interposed hetween periods of comparative tranquillity? These two opioions will probahly for some time divide the geological world ioto two seets, which may perhaps he designated as the Uniformitarians and the Catastrophists (WheweIl1832).
