AND DISEASES OF THE CHEST 249

physician and the physician specially interested in pulmonary disease. One would, however, in a book of this kind, published in I955, have liked to see some special reference to the lungs in the systemic collagen (connective tissue) diseases--viz., polyarteritis nodosa, disseminated lupus erythematosus, sclero- derma and rheumatoid disease. The chapter on " the pneumoconioses " is by no means comprehensive. The references at the end of each chapter refer in the main to Americanwork and the price of the book is inordinately high. Despite these criticisms, however, there is much to be learned from this work.

Primo-infection et Rginfe@on dans la Tuberculose Pulmonaire. By GEORGES CANETTI. Paris:l~ditionsMedicalesFlammarion. I954. Pp. 272. Illus. 2,375fr.

This book is a record of post-mortem observations on the results of primary tuberculous infection and reinfection carried out between I94o and 1944. The series consists of 3 ° i adult patients who had died from pulmonary tuberculosis, and an attempt has been made to trace the history of the infection from its onset, and its progress towards its termination. Phthisis is a disease which usually becomes clinically apparent many years after the invasion of the body by the tubercle bacillus and the picture is often confused by the occurrence of reinfec- tion, both before and after the original lesion has healed. The findings are discussed in painstaking detail, and the author claims that it is clearly established that phthisis due to reinfection is much more common than is a primary infec- tion in adults of any age-group. This observation is acknowledged to be at variance with the results of other workers, and the final conclusion would appear to be that adult phthisis does not follow any set course, and that either primary infection or reinfection may be responsible for adult pulmonary tuberculosis.

Die Bronchographie. By ERNST STUTZ and HEINZ VIle.TEN. Stuttgart: Georg Thieme Verlag. I955. Pp. viii+25o. Illus. D.M. 59.40.

Bronchus und Tuberkulose. By A. HUZLY. Stuttgart: Georg Thieme Verlag. 1955. Pp. vi i i+i38. Illus. D.M. 51.3 o.

Radiology is applied anatomy, and it is a pleasure to see that this fact, much neglected by radiologists in the past, has recently gained ground in the interpre- tation of skiagrams. The study of the lung in the living subject has thereby benefited, especially as regards the bronchial tree, with the help of broncho- graphy and bronchoscopy.

These methods have been applied and developed by the authors of both books. They refer to previous contributions of their own as well as to other literature, the list occupying forty pages in the book by Stutz and Vieten. Technique and interpretation of the methods are well explained in both books, notably with reference to pulmonary tuberculosis by Huzly and Boehm. Both volumes are splendidly illustrated and produced, although diagrams would have helped to interpret many of the photographs in Stutz and Vieten's work.

Knowledge of anatomy will be increased by radiological investigation of the o living subject and, conversely, the radiologist may profit from the conventional anatomy which, in the reviewer's opinion, has not been given sufficient recogni- tion in either book. The authors have, however, set down so much of their knowledge and experience that the books will be of value to both radiologist
