"Besides preparing a comprehensive text-book suited to present demands, Professor Le Conte has given us a volume of great value as an exposition of the subject, thoroughly up to date.

The examples and applications of the work are almost entirely derived from this country, so that it may be properly considered an American geology.

We can commend this work without qualification to all who desire an intelligent acquaintance with geological science, as fresh, lucid, full, and authentic, the result of devoted study and of long experience in teaching."-- _Popular Science Monthly._ _EVOLUTION AND ITS RELATION TO RELIGIOUS THOUGHT._ With numerous Illustrations.
