EACH issue of this work of reference adds new features without sacrificing the old. The arrangement of countries remains the same, except that the kingdom of Hejaz has lost its place among the independent states. It is in regard to India that the principal changes occur. That section of the book has been expanded from forty-four to sixty pages, the increased space being devoted to the provinces of British India and the independent states over which the Indian Government exercises certain control. Each of these entities is now treated in the same way as the provinces of other parts of the Empire. Among the introductory matter, which includes a section on the League of Nations, new features are sections on the International Institute of Agriculture, a list of European and North African air routes, and tables showing taxation, national debt charges, and paper currency of various countries. The coloured maps are two, showing the distribution of republics and other political divisions in the Soviet areas in Europe and Asia. In spite of additions the bulk of the volume is not increased.
