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 par- 

 ticularly 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." A ihcnaum.
