178 THE BRITISH J O U R N A L OF TUBERCULOSIS

line of differentiation clinically between bronchitis, asthma and emphysema," a view which, I think, is not held by aU physicians.

The chapters entitled "Mortali ty and Morbidity," "Clinic Pattern," " M u c u s " and "Clinical Management" are written by Dr. Oswald, and these will be of greatest interest to the physician. Little light is thrown on the ~etiology of the disease. The place of antibiotic therapy and its indications, according to the views of the author, is outlined. In the majority of cases we still have to fall back upon the well-tried remedies, a sedative cough mixture, the Brompton hot water medicine, and antispasmodics.

Dr. Lynne Reid has contributed a chapter on " T h e Pathology of Chronic Bronchitis." She considers that hypersecretion of mucus and damage to lung periphery are two essential phases of chronic bronchitis. Dr. G. Simon de- scribes the radiological appearances, which in the early stages are slight or non- existent. This chapter is well illustrated. Bacteriology is discussed by Dr. J. Robert May. He emphasises the tendency of infection to relapse after chemotherapy, due to the persistent growth of the H. influenzte. A very scholarly and interesting account o f " Air Pollution and Chronic Bronchitis" has been written by Dr. Patrick J. Lawther. Tests for " Disturbances of Re- spiratory Funct ion" are the subject of a chapter by Dr. David V. Bates. The pulmonary function tests indicate that a patient with chronic bronchitis does not breathe as well as a normal individual, but he breathes better than a patient suffering from emphysema. Many clinicians were already aware of this. Dr. Ronald Gibson is responsible for the chapter on " T h e Heart in Chronic Bronchitis and Emphysema." The book concludes with Dr. John Horder's contribution on "Aspects of Chronic Bronchitis in General Practice."

Thirty shillings is a large price to pay for this small, although well produced volume. G . E . BEAUMONT.

Selektive Lungenangiographie in der Praoperativen Diagnostik und in der Inneren Klinik. By Professor Dr. WILHELM BOLT, Professor Dr. WERNER FORSSMANN and Dr. HANS RINK. Stuttgart: Georg Thieme Verlag. 1957. PP. 199-

This excellent monograph on selective pulmonary arteriography is written by a team of experts, including Professor Forssman (Nobel prize winner), who was the first to pass the cardiac catheter in man and to obtain a pulmonary arteriogram.

The book opens with a detailed description of technique and indications for selective pulmonary arteriography. These general points are followed by an analysis of the various pulmonary vascular patterns and specific pathological appearances of the pulmonary arteries and veins in various pulmonary dis- orders, acquired and congenital heart disease. The results of this new method of investigation of the lesser circulation are further correlated with lung function studies and hmmodynamic findings of cardiac catheterisation. A wide selection from a total of 2,0oo pulmonary arteriograms forms the basis of this analysis.

Pre- and post-operative angiographlc studies of patients who were sub- mitted to various forms of thoracic surgery are of particular interest, and so are the findings in the lesser circulation in patients with acquired and congenital heart disease complicated by pulmonary hypertension.

AND DISEASES OF THE CHEST I79

Reproductions throughout the book are of the highest quality, a great tribute to the publishers. For those who are interested in the pathological physiology of the lesser circulation this volume is a most valuable and timely addition to the many publications which have appeared in recent years.

Current Medical Research. A reprint of the articles of the Report of the Medical Research Council for the year J955-56. London: H.M. Stationery Office. 2s. 6d. net.

IN the first pages of this publication an account is given of the Council's development of policy in the last few years in regard to clinical research, and of the various ways in which allocations of grants are determined in order to further research, whether centrally organised or decentralised.

The later and major part of the brochure consists of reprints of articles from the Council's Report to Parliament for the year.

The field covered by the thirteen reviews is extensive, including as it does observations on Lung Cancer of special interest to readers of this journal; Poliomyelitis Vaccination; Vaccination againt Pertussis; Protein Deficiency in Man; Growth and Renal Function; Abnormal Hemoglobins; Microbial Gene- tics; Radiation a n d Transplantation Immunity; Radiati6n and Leukemia; Chemical Aspects of Antibiotics; and Mass Spectrometry for Gas Analysis in Respiratory Research and Clinical Practice.

A considerable amount of recorded fact has in these reprints been concen- trated into relatively small space, and the articles are well documented. It seems hardly likely, in our view, that they will make much appeal to the lay public; but to the genuine medical or scientific research worker, in the earlier stages of his or her career, this publication should prove a valuable mine of information and a real help in constructing the initial plan of investigation.

Guide Technique et Topographique d'Exploration Bronehologique (Bronchoseopie et Bronchographie). By J~.AN IOAN~OU, Medecin-adjoint au Sanatorium de Chevilly; Attach~ de Bronchoscopie ~t la Clinique de Pneumo-phtisiologie de la Facultfi de Paris. In collaboration with A . DuCn~T-SucHAUX and A. PINELLI. Preface by Docteur P. CHADOURN~.. Paris: Masson et Cie. Pp. i 14. 66 figs. Fr. 1,4oo.

This monograph is presented exactly twenty-five years after the publication of the classical work of Sicard and Forestier on the use of Lipiodol in diagnosis and treatment. The interval has seen great advances in our knowledge in many respects, notably in the development of the technique of bronchoscopy, in bur understanding of the anatomy of the bronchial system and, not least in importance, in the chemical composition of the contrast media which can be employed in bronchography.

Bronchoseopy and bronehography have now become a basic feature of the investigation of chest disease. They provide information which is funda- mental in considering problems of diagnosis, location of lesions and treatment.

About a third of the book is devoted to a detailed consideration of the anatomy of the bronchial tree, with its variations in health and in disease.
