The Age of the Earth, and
other Geological Studies

By W. J. SOLLAS, LL.D., D.Sc., F.R,S.
Professor of Geology in the University of Oxford
Illustrated.

This volume, while written by one of the foremost of English geologists, will be found interesting and attractive by the reader who has no special knowledge of the science. The essay which gives the book its title sets forth the bearing of the doctrine of evolution on geological speculation, and particularly on the vexed question of our planet's antiquity. The subjects of the other studies include the following: The Figure of the Earth, and the Origin of the Ocean; Geologies and Deluges; the Volcanoes of the Lipari Isles; the History and Structure of a Coral Reef; the Origin and Formation of Flints; the Evolution of Freshwater Animals; and the Influence of Oxford on Geology.

"They range over a great variety of subjects, including many which are of sufficiently wide interest to bring the geologist into sympathetic touch with the general reader. What educated man can fail to be interested in such subjects, for instance, as the age of the earth, the building of coral islands, the cause of volcanic action, or the Deluge? Of all these matters the Professor discourses pleasantly and well, writing with command of much scientific learning, yet always readably, sometimes with brilliancy of diction, and occasionally with a touch of humour."—Athenæum.
