Auerbach (surgery, Stanford U.), one of the foremost authorities on emergency medicine in the US, has revised and updated his 1986 manual and added over 250 illustrations. He suggests what to do in cases ranging from minor disturbances such as bruises, diarrhea, and blisters to major emergencies such as head injury, fractures, seizures, burns, and poisoning. He suggests reading it before hitting the trail, and also taking it along. He includes a glossary without indicating pronunciation. Annotation c. Book News, Inc., Portland, OR (booknews.com)
