This is the second volume of a new, comprehensive treatise on physical chemistry which should prove to be a work of first-class importance. Its wide scope makes it extremely valuable for reference purposes while, at the same time, it has been kept intelligible to readers without advanced knowledge of mathematics and physics. It is fully illustrated with figures of apparatus, graphs and other diagrams and lays unusual emphasis on the experimental. In addition to descriptions of apparatus and experimental methods, valuable and comprehensive collections of numerical data are given; most of these tables are compiled from material not easily accessible and scattered through a large number of periodical publications.

Amongst the other outstanding features of the work are very full references to the literature of the subject including the important classical publications as well as recent work. There are bibliographies of each topic and an extensive collection of empirical or semi-empirical formulae likely to be of use to laboratory workers and to chemists and engineers engaged in large-scale work.

This volume deals with the properties of liquids. It includes the theory of the liquid state, density, thermal expansion, solutions, compressibility, viscosity, thermal conductivity, surface tensions, specific heat, vapour pressure, boiling point and latent heat.
