Chemical Oceanography, Editors: J. P. Ratty and G. SKn~ow, Academic Press, London and New York, 1965, Vol. 1, xix + 712 pp. IN THE preface the editors note that they : " h a v e invited a number of specialist authors to contribute chapters for a comprehensive textbook on chemical oceanography to cover the chemistry of the sea, the interaction between the components of sea water and marine life, and the geochemistry of marine sediments". The growth and complexity of the subject is shown by the fact that it has provedimpossiblc to cover these subjects within a single volume. Although this book is intended primarily for research workers and final year honours undergraduates in chemical oceanography and marine geochemistry, the presentation of each chapter is such that most of the material can be read and understood by readers at all levels, provided that they have a modest knowledge of chemistry. Thus, it is hoped that the book will be of value to workers in related fields, such as marine biology, and will give an authoritative and comprehensive coverage of the many facets of this rapidly expanding subject. Volume 1 deals with sea water, its chemistry and the processes controlling its composition, and with the interaction between marine organisms and the nutrient elements and compounds. Volume 2 contains topics of radio-chemical, analytical and geochemical interest." The thirteen chapters and their authors are : Historical Introduction, J. P. RILEY; Currents and Mixing in the ocean, K. F. BOWDEN; The Physical Properties of Sea Water, R. A. Cox; The Major Constituents of Sea Water, FREDERICKCULKIN; Minor Elements in Sea Water, EDWARDD. GOI~aERG; Dissolved Gases other than Carbon Dioxide, FRANCISA. RICHneSS ; The Dissolved Gases-Carbon Dioxide, GEOFFREYSgaggOW; Phosphorus, F. A. J. ARMSTRONG;Inorganic Nitrogen in Sea Water, RALPH F. VACCAgO;Silicon, F. A. J. AgMSTgONO;The Dissolved Organic Constituents in Sea Water, E. K. DUURSMA;Production of Organic Matter in the Primary Stages of the Marine Food Chain, J. D. H. STgaCKLAND;and Anoxic Basins and Fjords, FRANCISA. R I ~ S . This, the first of a two volume series, is a major contribution to the literature of oceanography. Here for the first time, in a series devoted exclusively to the chemistry of the marine environment, the main topics of chemical oceanography are discussed in depth by authors who are actively engaged in research in the specialities about which they have written. References at the end of each chapter are adequate and in some cases copious. The result is a volume which achieves the objectives of the editors. D. E. CAgRrrr M.I.T, Cambridge, Massachusetts.
Biology of suspension feeding by C. BARKER JORGENSEN. (Pergamon Press, International Series of Monographs in Pure and Applied Biology. Zoology Division. Vol. 27. (1966). Price 80s. ($12.50), 374 pp. THE author is to be congratulated on producing a book which can be read with pleasure and ease by the advanced student of zoology. He has undertaken considerable research, as indicated by the references, to bring into perspective the various aspects of a problem which has interested him for a number of years. Skilful attention is given to the details which are selected to establish conclusions, and the reader's attention is held by a logical approach and a number of thought-promoting ideas. The book is divided into three parts. The first deals with the gross structure, the functioning and the efficiency of the feeding organs of invertebrates investigated by other workers, and, quite rightly, presupposes some knowledge of the functional anatomy of these animals. It is illustrated by a series 977
