Rocks and Their Origins

Rocks and Their Origins is a really excellent little book. Though a geological subject, it is intended primarily for those who are not specialists in geology, and as such necessarily presents the subject-matter in a simple, direct manner. But while declaredly a brief non-technical discussion, addressed to a general scientific audience, the charcter and treatment of the material selected are such that the more specialized student feels instinctively the complete command of the subject which alone makes possible such a succint statement. There is so much meat condensed in these brief paragraphs that anyone interested in the subject finds himself continually calling for more and wishing that the treatment were fuller.

This work was published as one of the long series of "Cambridge Manuals of Science and Literature".
