Abstract
THIS small book is interesting, up to date and well-illustrated. It opens with a chapter giving a very useful account of the physical properties of rocks of various kinds, particularly of their density, elasticity, and magnetic and electric properties, with a brief notice of the methods of determining such properties of natural rocks. The high electrical conductivity of sulphide rocks is specially noted. The second chapter discusses the methods of geophysical investigation, magnetic, electric, gravimetric and seismic; the relative costs of the different methods are indicated. In the third chapter, the results of many such investigations are described, with maps and diagrams. The book concludes with a brief account of the application of geophysical methods for economic purposes, namely, for mineral prospecting, for the discovery of underground water, and for the investigation of the suitability of land on which large buildings are to be erected.
