The author discusses the movements of the joints of the body in terms of the interplay of various muscles. The text is readable and informal but anatomically sound, proceeding systematically from lower extremities and trunk to upper extremities and head. It is illustrated with excellent drawings and photographs, some of which are amazing; examples are figure 61 showing a paraplegic boy who has become accustomed to walking on his hands and figure 82 showing a roentgenogram of a contortionist's vertebral column. A study of the illustrations will quicken any student's interest in anatomy, and a careful reading of the text would constitute a good review of many aspects of the subject. A copy of this book should be accessible in every library used by students of medicine and physical education.
