Excerpt from Science Progress in the Twentieth Century, Vol. 7: A Quarterly Journal of Scientific Work and Thought, July 1912 to April 1913The publication Of a third edition Of Sir G. H. Darwin's well known semi-popular book on the Tides 1 affords an Opportunity Of forming an estimate Of the advances that have been made in recent years in knowledge concerning all those geophysical phenomena which either are directly due to the forces that cause the tides or share with these direct effects some feature rendering them amenable to discussion by similar methods. Sir G. H. Darwin is the greatest living authority on these questions and the fact that nearly one quarter Of the third edition Of his book is either added or rewritten is sufficient evidence that substantial advance has been made. This advance is not confined to the theory but extends also to the methods Of Observation and the devising Of suitable instruments, besides including a very great increase in the mass of records that are available for the comparison Of theoretical results with Observed facts. On the purely Observational Side, perhaps the greatest novelty is to be found in the beginning Of actual measurements Of the range of the tide in the open sea. On the purely theoretical Side, the modifications Of Laplace's nebular hypothesis which have been suggested by various writers are specially attractive. But the advances that Will prove most interesting to many readers have been made by combining theoretical con siderations with Observational results in regard to several groups Of phenomena from which conclusions have been drawn as to the_interna1 constitution Of the Earth. We propose to consider these matters in order.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
