THIS book will serve the useful purpose of directing popular attention afresh to the important questions of education and scientific research in relation to national prosperity, on which so many eminent scientific men have given emphatic warnings. It is the joint production of a scholar and of a man of business, and although primarily addressed to the man in the street, deserves attention from everyone concerned with education or with commercial manufacture* Its principal aim is to show that Great Britain, which forty years ago was the workshop of the world, is so no longer. It supports this statement by an inquiry into the reason for this decadence and by useful statistics. Eclipse or Empire? By Dr. H. B. Gray S. Turner. Pp. x + 316.
