This is an interesting monograph on a subject about which much has been written but apparently not in as complete a form as is presented here. Twenty-six pages are devoted to a description of the anatomy and physiology of the bronchi. The bulk of the book is devoted to a discussion of the pathogenesis and a description of the pathologic anatomy of bronchiectasis, and the remainder to the clinical aspects and to treatment. As surgical treatment is the one of choice, the subject is covered in a few pages. One who is interested in bronchiectasis will find ample and excellent discussions of the subject, a wealth of material gleaned from well over two hundred references, a consideration of a good deal of controversial matter, of which there seems to be no lack, and beautiful illustrations and makeup. A short summary, barely a page, tells the authors' opinions on the subject.
