This neat volume includes a series of papers on the musculoskeletal system presented at the Twenty-Third Graduate Fortnight of the New York Academy of Medicine. The first papers deal with the structure and chemistry of connective tissue and with the physiology of muscle and of bone. The last half of the symposium is more concerned with clinical matters. The authors of the various papers are well known in their field and speak with authority; there are illustrations and lists of references. An index is lacking.
