sons, except in a limited role of reference for a specific topic. It is an excellent book for the biologist, particularly the aquatic biologist, and is highly recommended for their general use. In addition it is a fine reference for those concerned with developing, establishing, and planning programs of water pollution control. It is unfortunate that the word "control" has been used in the title of the book. A more accurate title would have been simply Biology and Water Pollution. There is insufficient coverage of the control aspects of water pollution to merit use of the word. Mr. Warren is to be congratulated for this fine book which should help to provide a more comprehensive understanding of the biological aspect of water pollution. Students of aquatic biology are indebted to him for combining so much interrelated and interdependent material into a single text and for doing so with clarity and sensitivity.
