STUDIES of the detailed structure of the reaction zones of flames have been greatly advanced by the recent use of physical and chemical techniques such as the optical study of refractive-index gradients, detailed temperature tracing with small thermocouples, mass spectrometry, optical spectroscopy,

✦ Synopsis
Chapter 12, the most original chapter in this part, reads like an abstracted version of former Chapters 6 to 10. Chapter 13 on analog computers appears almost identically in both texts. It is regrettable that the author did not expend more effort on this part, where he previously demonstrated competence, and write a new, more modern treatment of the subject.
Part IV, 'Electromechanical Energy Conversion,' is composed of a chapter on magnetization, concepts and computations, a second chapter on transformers, with discussions of phasor diagrams, an equivalent circuit and no-load tests, and a third chapter on motors, including induction, synchronous and d-c machines. The material is adequately presented although some may question the author's choice of emphasis. While an entire chapter is devoted to transformers, no mention is made of mutual inductance nor of self-inductance, of forces on moving charges in a magnetic field nor of forces on current carrying conductors. As in many traditional texts on motors, m~ny detailed formulae appear with only slight derivation and motivation.
The book has many shortcomings, but within its scope and limitations in size, Professor Del Toro has written a clear and easily understandable presentation of electrical engineering. It should serve its purpose as an introductory text for nonomajors, and also be useful to the practicing engineer who wishes a concise review of the field. With its numerous examples and well-selected problems, this text may be welcomed by many teachers.
