SCIENCE OF THE SEA 



AX ELEMENTARY HANDBOOK OF PRACTICAL OCEANOGRAPHY FOR 



NATURALISTS, TRAVELLERS, SAILORS, AND YACHTSMEN. 



PREPARED BY THE CHALLENGER SOCIETY FOR THE PROMOTION OF THE 



STUDY OF OCEANOGRAPHY, AND EDITED BY G. HERBERT FOWLER 



With numerous Illustrations and Diagrams. 6s. net. 



The primary aim of the book is practical— namely, to teach men with no scientific training how 

 they can do useful work for the advancement of science ; it deals with the various aspects of the 

 ocean chapter by chapter, points out where new or renewed observations are needed, and includes 

 only sufficient theory to enable the observer to understand what kind of a brick he is building into 

 the pyramid of knowledge. 



The book has been written entirely by practical specialists. Being addressed, in the first instance, 

 to non-scientific readers, it has been phrased as far as possible in simple English ; but it will be found 

 useful by many who already know something of Oceanography.
