This treatise discusses comprehensively the various diseases which affect the structures within the chest. Thus there are included not only such processes as tumors, abscess and bronchiectasis but also conditions like acute pneumonia and bronchial asthma. Pulmonary tuberculosis is thoroughly gone into, although only a small paragraph is devoted to streptomycin, which is so much to the fore today. The anatomy and physiology of the lungs are adequately discussed, and the sections on surgical procedures are useful. As Dr. Rubin points out, roentgen diagnosis is emphasized, and there are over three hundred admirable reproductions of roentgenograms dealing with every sort of pulmonary disease. This is an unusual and certainly invaluable feature of the book.
