This short volume differs from the previous monographs of Trihalat (1957) and Druce (1048) in that the main emphssis is on the occurrence, separation, and production of the element. The only chemistry considered is that related to production processes. Since the original Russian publication is based on the Literature up to 1959, this volume is already slightly out of date. Although naturally the Russian practice is emphaeized, the foreign literature is adequately covered. Information an the prediction, and discovery of rhenium are very hriefly covered in Chapter I. Chapter I1 contains considerable detail on the properties of rhenium metal, its alloys, oxides, and perrhenates; while the uses of rhenium are discussed in Chapter 111. Production data are also included in Chapter 111, although the date. for Russia are curiously missing. The geochemistry of rhenium and the recovery of rhenium from molybdenum sources are discussed in Chapter IV. The methods used for the extraction of rhenium compounds, complete vith flow sheets, are discussed in Chapter V. Chapter VI is devoted to methods of reduction to the element. Chapter VII briefly deals with the analytical chemistry. Although the reviewer cannot vouch for the accuracy of the translation, the English version certainly is readable. The average chemist probably will not he interested in purchasing this book unless he is specifically interested in this element.

The only chromophore discovered to date in the 20th century is "Phthalocyanine." The name, coined by R. P. Linstead, means "rock oil dark blue." The authors have performed a major service by condensing its literature, to mid-April, 1962, into book form. Long lists of references follow each chapter. (Continued on page A976)
