The authors of this ambitious work have compiled in a relatively small space information on three vast subjects: enzymes, endocrine principles and vitamins. No bibliography is included, seriously limiting the usefulness of the book. To review in detail so prodigious an accumulation of data is not feasible. Inevitably the authors have omitted much of importance and have included a good deal that might better have been deleted. However, for those whose knowledge of the subjects considered permits them to separate the facts from the less precise material included, this book may be used for reference. Its value as a textbook appears limited.
