The Deposits of the Useful Minerals and Rocks. Translated by

S. J. Truscott. Vol. I. (Macmillan and Co. 18e. net.)— Mr. Trnscott'a object in making this excellent version of a well-known German work on applied geology was twofold- " firstly, to school myself in the matter of ore-deposition," and, secondly, to be of service to English mining engineers. He states that be has succeeded in his first object, and we have no doubt that his second will also be attained. The original authors are Professors F. Beyschlag and P. Krusch, of Berlin, and Professor J. H. L. Vogt, of Christiania.
