A Study of the Oceans


    PROF. JOHNSTONE'S study of the oceans is brief but it touches many aspects of the subject. After a chapter on the origin of the earth and the geological history of the oceans and continents, he goes on to discuss the classical geography of the oceans, tracing the development of knowledge, mainly of the superficial extent of the oceans, up to the present time. The second half of the book contains chapters on the physical and human geography of the great ocean basins. No one could complain of lack of interest in the volume, but it is possible to suggest that too much has been tried within the compass of some two hundred pages. The present issue is the second edition, which differs from the first mainly by the addition of a number of short appendices on isostasy, the Wegener hypothesis, methods of navigation, and the tides. There are numerous sketch maps.
