The Pulse of the Earth

Problems of current interest relating to the earth's physical history will be discussed in this volume. Each chapter constitutes a subject in itself, but the sequence I have chosen will, I hope, show and explain the deeper correlation of several terrestrial pro­ cesses which, at first sight, ap...
