Abstract
THE above three volumes issued by the Imperial Institute form a further contribution to the series of monographs on mineral resources which the Institute has issued from time to time, and these follow closely the lines upon which their predecessors have been laid down. Each book consists of three sections, the first dealing with the characters and composition of the ores of the metal treated of, the uses and properties of the metal and of its more important alloys, and the metallurgy of the metal, that is, the processes by which it is extracted from its ores. The second section gives an account of the distribution and occur rence of the ores of the metal within the British Empire, these occurrences being described in some little detail; the third section describes the sources from which the ores of the metal in question are obtained from foreign countries, that is to say, countries outside of the British Empire. Statistics of production are usually given, though these are to-day of comparatively little import ance in view of the fact that full official statistics are published regularly by the Imperial Mineral Resources Bureau. Each volume, however, concludes with a very useful bibliography of the metal to which the volume refers.
