Abstract
SO much has recently been written on the theoretical aspects of the conduction of electricity by metals, of the problems of supra-conductivity, of the poor conductor and of galvano-magnetic effects that it is very satisfactory to have available this excellent book on the experimental side. For it marshals the experimental facts in a handy manner, and deals with the proof of fundamental laws like that of Ohm and with the more recent characteristic temperature relations such as that of Griineisen, and illustrates them with a wealth of experimental data which can only be found with difficulty elsewhere. The technique and results of modern work on resistance of metals under pressure and on the influence of magnetic fields upon resistance are well described. The survey of the electrical behaviour of alloys is adequate and special attention is paid to the resistance of powders. The determination of the Wiedemann-Franz ratio is fully discussed and the data well considered. Supra-conductivity, naturally, receives very full treatment from W. Meissner, and many readers will find the section of the book which deals with it particularly valuable. Some discussion of photo-electric effects is given, but as these were fully treated in vol. 23 (Part 2), only special features are dealt with here. The first part of the book closes with an interesting outline of modern theories of electrical conduction.
