This 400-page second edition has been revised, after four years, expressly with an eye to the full-time emergency room physician, although it will probably still appeal mainly to the medical student and junior house officer newly assigned to duty in the emergency room. Several chapters have been completely rewritten and one on drug abuse added. In general, the book is informative and to the point, well organized, and adequately illustrated. Many of the chapters are organized in a 1-2-3 "cookbook" fashion which should be both appropriate and appealing to the reader for whom it was written. Of equal importance in a book of this type is a good cross-referenced index which unfortunately this book lacks. For example, the discussion of the approach to loss of vision in the book is excellent but neither "blindness" nor "loss of vision" are listed in the index. "Insect bites" are not listed, "stings" are.
