Subsequent to the publication of the first edition of this book in 1914 the World War stimulated research and discovery in many directions. Moreover, the volume has become a classic work of reference. This edition covers such new subjects as artificial silk, television and phototelegraphy. The chapters of special interest to physicians are those on electricity, artificial production of cold, chemistry and radium. The illustrations are well printed and the index is good.
