The authors have selected their material from 1,452 roentgenograms, based on the studies of 312 postmortem examinations between 1949 and 1953, classifying the various lesions under eight principal topics relating to the lungs, brain, heart, kidneys, aorta, fetal specimens, portal system, and the greater circulation. An introductory chapter details the methods of investigation. Special tribute is merited by both the authors and the publishers for the excellent illustrations. The European custom has been followed in that the reproductions of roentgenograms are in the positive rather than in the negative like the original films, but this is an advantage in that more roentgenographic details have been preserved. In any event, any physician doing fluoroscopy knows that he must read positives as well as negatives. Each chapter is followed by a very satisfactory detailed summary of the principal deductions justified by the cases presented; this is done in French, English, and Spanish.
