Book Reviews The next nrticle by Bon&-Bruevich uses the Kubo formitlism to discuss eleetiomagnetic transport in solids. It iu rather similar in intent to Ehrenreich’s lecture. Velioky then follows the lines laid down by Born&Bruevich to discuss the polaron problem and exemplifies his discussion with a deviation of the polaron masz in the weak ooupling limit. A short lecture by Johnson on phononphoton interactions includes a discussion of the shell model used in lattice dynamics calculations. The use of infra-rod absorption and Raman aoltttering in the analysis of phonon dispersion curves is also indiaated. An article by Anton& follows on the interpretation of quantum efficiency experiments in semiconductors. In the concluding article Burst&n, el al. compare the optical properties of thin and thick slabs.
SIX LECTURESON MODERNNATURALPHILOSOPHY, by C. Truesdell. 117 pages, 6 X ‘J in. New York, Springer-Verlag, 1966. Price, $4.60. These six lectures on natural philosophy, offer it very clear, simplified presentation of Nell’s theory of simple materials, Coleman, Miael, and Nell’s studies in cor~tinuum thermodynamics, and Toupin’s work on oriented materials. Included also is a lectux on the olassiral ergodic problem ~8 treated by Kbinchin and Lewis, as well as a lecture on the To+-Rivlin theory of electro-magnetic nave propagation. Truosdcll concludes with R stimulating essay on method and taste in netural philosophy, which summPrriees a modem view of the subject better than any other known to this reviewor. It is recommended for every serious Ytudent of seicnce or engineering.

This Russian translation is a very welcome addition to the body of heat trzmafer literature in English. The material arises apparently from the work of staff and students in the institute with whichProfessor Kudxyyavtaevis associated. It is a collection of separate, though related, contributiona and considerations. This short book concema the conduction mode. It considers, pragmatically, two aspects of bow one should treat conduction transients in ordinary and in extreme circumstances. The two aspects are considered in two separate psrts. The first is the question of appropriate boundary conditions (surface conditiona), their effeot on conduction solutions, and the inference of proper boundary conditions from measured transient responas in the conduction region. Questions of physio-chemical changes and radioactive energy &eats are diaeuuued. There is also a discussion of several instrumentation and measurement techniques. The seaond part of the book eoncenxe several techniquw for the measurement oi material properties needed for oonduclion itnnlysis. In determining properties from transient response, an electron gu* caiortieter is described ~8 a method of introducing xeurately known thermal energy inputs. COF roctions ae discussed. Subsequent material pmwmta vzults of the use of this technique on different actual materials of differing sbalx and dimensions. This book should also be interesting to the non-Russian portion of the heat transfer oommunity a6 an intimate view of the concerns and methods of a considerable group oi Russian researchem Details given on instrumentation and on instrument oapability are highly informative. In addition, since virtually all of the work and references cited itre Russian, the material is a representative sample of recent work in this area of heat transfer. BENJAMINGEBHART
