Volume XVIII.

DARWIN’S CORAL REEFS, VOLCANIC ISLANDS, AND SOUTH AMERICAN GEOLOGY: With Critical and Historical Introductions, specially written for this edition by Professor John W. Judd, F.R.S., Professor of Geology in the Normal College of Science, South Kensington. With Maps and Illustrations.

Darwin’s “Coral Reefs” is at once one of his most notable and charming books, and one that has excited a most vigorous recent controversy. His account of the Volcanic Islands he visited, and his still more remarkable book describing the vast changes that have taken place in South America in geological time, are also reprinted in this volume, thus completing the “Geology of the Voyage of the Beagle.”
