Abstract
THE second volume of Prof. Becquerel's treatise on physics contains sections on elasticity and sound, the former subject occupying about one-quarter of the available space. The first chapter deals with the physical study of elasticity and the determination of the elastic constants; the second treats of the mathematical theorv of elasticity. On the experimental side particular attention is given to the researches of Wertheim and of Amagat; on the theoretical side the aim has been to emphasise only essential questions and to derive the formulea necessary for the propagation of waves in a homogeneous, isotropic medium. This discussion paves the way for the treatment of wave propagation in the next chapter, which deserves special mention for lucidity of treatment. In fact, throughout the volume the author gives an exceptionally clear exposition of what may be termed the classical theory of acoustics. Stress is laid for the most part on the mathematical rather than on the experimental aspects of the subject, but there is a valuable chapter dealing with the applications of acoustics in music which is unusually complete for a book of this character.
