THE sixth volume of this useful work, which now appears in a handier form than that of the first two volumes, treats of travel in Canada, the Argentine, Madagascar, tropical West Africa, and Oceania. The articles vary in scope and treatment, as is obviously desirable in such diverse regions, but all are of an entirely practical character and should be very helpful to the scientific traveller. No attempt is made to compete with volumes on various aspects of the countries or to furnish guides or handbooks. Attention is concentrated on methods of travel, equipment, maps, food, and manners and customs that might affect the traveller. The articles on the Argentine and West Africa are specially valuable, but all are useful and are written by men of practical experience.
