Structural Geology. By C. K. Leith. (Constable and Co. 69.

6cL net.)—Mr. Leith, who belongs to the University of Wisconsin, deals in this book with "the interpretation of structures produced in rocks by earth movements." His purpose is the study of rock structures, not for their own sake so much as for the light they may throw on economic; geology and on the history and configuration of the earth. His examples are chiefly drawn from the United States.
