A clear, well-executed polychrome map, evidently copied from the one recently published in England, if not actually printed there. It exhibits not only the route of Dr. Livingstone during the period included between the years 1866 and 1872, and that taken by Mr. Stanley in his recent search, but also the course which the former proposes to follow in the prosecution of his discoveries. The boundaries of lakes and the courses of rivers, where definitely known, are indicated by unbroken lines--where still supposititious, by dotted ones. The map, which is printed on heavy paper, is thirteen inches wide by eighteen inches long, and being folded within a stiff duodecimo cover, can be easily preserved and readily consulted. _Books Received_.
