The author of this little book has collected and revised a group of postgraduate lectures aimed to give the essential clinical features of those disorders commonly grouped together as chronic rheumatism and to outline methods of treatment which he has found useful. The result is a book of seventeen chapters in which are discussed briefly the classification, theories of etiology, clinical features and treatment of rheumatoid arthritis, chronic villous arthritis, osteo-arthritis, spondylitis, fibrositis and gout. The author makes no claim toward thoroughness of discussion and cites the literature only occasionally. A short bibliography, however, is given at the end. Many useful hints for treatment are included and some suggestions are made which have not yet been generally accepted.
