for the conquest of space. From a handful of dedicated individuals there has been such an expansion t h a t hundreds of thousands are engaged in either design, construction or development of these devices. Thus, there has arisen a critical need for a reference book which can answer questions posed by the serious worker or newcomer to the field. As Dr. Theodore von K a r m a n indicates in his foreword: "we realize it is progressively more difficult to keep abreast of all phases of rocketry. The 'solid propellant' man gets so engrossed in the myriads of problems involved in his specialty t h a t he cannot always keep up with the 'liquid propellant' man's problems, and vice versa." Dr. yon Karman stresses the need for an encyclopedia presentation of the material available on specific research and design problems. Rocket Encyclopedia Illustrated has been written to fill this gap and with it the compilers, John W. Herrick and Eric Burgess, the two ranking authorities have undertaken a most difficult task. They have carefully checked the available data and have selected only those entries necessary for an understanding of rocketry. The result is this new, fascinating and completely essential compendium. Thousands of entries are alphabetically arranged in the book. The subject leads off with the name of the entry which is followed by the definition of the term. This is followed by the exploration. A significant feature of the new explanation section is the introduction of some terms in italics. Where the editors believe further clarification is necessary, additional terms are italicized indicating entries. A further feature which sets this encyclopedia apart from the run of the mill type is the "visual keying" used in the illustrations. Each part of the illustration identified by a call out is also indicated in bold face type where it appears in the accompanying text. An appendix is included which contains photo credits, a bibliography and references, abbreviations and symbols used in rocketry. The editors have compiled a much needed and magnificent contribution to rocketry and are to be congratulated ou their final product. The natnre of this book is such t h a t no school, laboratory or technical station can afford to be without one. It should enjoy a wide distribution. I . M . LEVVrT Franklin Institute Planetarium

FLUIDIZATION, by Max Leva. 327 pages, diagrams, 6 X 9 in. New York, McGrawHill Book Co., Inc., 1959. Price, $11.50. Fluidization is one of the newer unit operations which became important during World War II when it was used by the oil industry to upgrade petroleum stocks to high octane gasolines. Developments have been rapid since t h a t time and fluidized beds have been used by many other process industries. Until the publication of Fluidization only one important book on the subject existed. It was based on a collection of papers and coitsequently did not adequately cover all aspects of the science. Mr. Leva has previously established a reputation for basic investigations in the mass transfer operations. This book contains the same thoroughness typilied by his publications in solvent extraction. There is a very unusual feature in this text. Every chapter is organized so that the sequence of developments, and the research approach are explained. "['he attthor not only SUlnmarizes the important conclusions lint indicates those facets requiring additional exploration. Many industrial laboratory studies and thesis subjects are contained ill Mr. Leva's summations. Of the ten chapters, the principle ones describe the fluidized state, fixed bed and the onset of fluidization, the expanded bed, elutriation, dilute phase and moving solids. Related chapters concern the spouted bed, mass and heat transfer, and solids and fluids mixing. Graphical presentation of analytical data is liberally used to summarize the results. Reference tables, dimensional analyses correlations, and schematic diagrams are abundant. A bibliography of the important literature is appended to each chapter. Some sample problems and their solutions are presented. This will facilitate the use of the book as a text. Additional problems for classroom or student use are offered. The author avoided a strictly "application viewpoint" in preparing Fluidization. Fundamentals have been stressed. This is wise since future development may be expected and subsequent editions will be easier to update. Chemical engineers and students of the fluidization unit operations will find this to be a valuable addition to the technical literature 1).. A. I~aKV:I< ]'he Frankh'n [ns/ilute Laboratories
