This book is a collection of approximately 25 papers by authorities in every field related to the physiology and medicine of diving and compressed air work. It is remarkably well edited so that a flow of thought from one author to another has a continuity seldom achieved in a multiple-author volume. It will be especially useful to those interested in underwater environmental studies and the study of speleology. Emphasis is made on the compressibility of water at great depth such as in the Mariana Trench, and discussions relevant to the physical and chemical changes that occur are lucidly and interestingly presented. Life is found at all depths. The problems of oxygen toxicity are thoroughly discussed as well as the history of early decompression studies. Each chapter is supported by bibliography.
This book is highly recommended, first as a subject of general interest—to the layman, the scuba diver, and the
