V o m m 1of this monumental work s p peared in 1949 [reviewed in J. CKEM. Eouc. 27.50 (1950)l with the promise that Volume 2 would complete the work. The manuscript was essentially complete a t the time of Dr. Jacob's death in 1955. The book is thoroughly up-to-date, s h a m by sections on transpiration cooling, of importance in jet engines, and heat trsnsfer in liquid metals, of importance in nuclear reactors. Volume 2 continues from Volume 1, starting with Part F on radiation, eontaining Chapter 31 on radiation through a nonabsorbing medium and Chapter 32 for an sbsorbing medium (a. total of 146 pages). The remainder of the book contains Part G on selected fields of application (414 pages), Part H with supple-

ments to Volume 1 (40 pages), and the appendix for Volume 2 (52 pagcs). The selected fields of application are thermometry and temperature measurement, heat exchanges, regenerators, cooling towers, cooling by falling liquid films, cooling of surfaces exposed to hot gases, heat transfer through laminar boundary layer a t high fluid velocity, heat transfer through turbulent boundary layer a t high fluid velocity, and steady-state heat transfer in packed columns. Because of the advances in heat transfer, Part H gives material t o supplement the various chapters in Volume 1. This includes new equations, tables of data, references to important papers, and additional problems. The appendix t o Volume 2 gives a. series of problems, table of nomenclature and conversions faotars, literature cited and the index. Those who have used Volume 1 will want to complete their set. Many engineers who see the applications in Volume 2 will want both volumes. It definitely is a graduate and research level treatise. Engineers dealing with heat transfer owe much to Max Jacob for his lifetime of research and writing in this field. UNLVERBITI (I* TEXAS AUBFIN.T E X A ~

FOE once, a mechanical engineering thermodvnamies text does not introduce

energy from its source t o its utilization, i.e., Source, Storage, Liberation, Transitian, Transformation, Transportation, Utilization. This logical but novel approach changes markedly the arrangement of this text to one in which the student grasps more readily the new concepts as they arise. Entropy now IogicaUy appears in Chapter 11in the section on Energy Transformation8. Nuclear and chemical energy are not overlooked as energy sources. Why can't the mechanical engineer learn t o use the mole as a mass unit t o simolifv his eas and

frigeratiion cycles. Free energy and work functions are still unmentioned when the boak ends. This is an interesting book with a novel annroach. It is worth readine and usinn ing thermodynamics. KENNETH A. KOBE U N ~ Y ~ R ~ Ior T YT E X * ~ IOBTIN, TEX*~
