Coral reefs, by Charles Darwin. The volume also includes geological observations on the Volcanic Islands, and parts of South America, visited during the voyage of H.M.S. Beagle. It contains excellent maps, plates and numerous illustrations, together with a critical introduction by Prof. John W. Judd, F. R. S. Although in some respects more technical in the subjects and style than Darwin's Journal the matter reprinted in this volume will never lose its value and interest for the originality of the observations contained. Many parts are admirably adapted for giving an insight into problems regarding the structure and changes of the earth's surface. It forms an excellent introduction to physical geology and physiography in its application to special domains. Both the student and general reader will be glad to obtain so important a work in so cheap and convenient a form. It is liberally illustrated with maps, charts and drawings.
