bacterial drugs in 4 ° patients with pulmonary tuberculosis. All were later operated on, and the post-operative condition of more than half of them was found tO be better than had been expected. T h e other unpublished p a p e r is the report of an address given in I953 by Dr H. Nicholson on the value of artificial pneumothorax treatment. The reprinted articles cover a wide range, from mitral stenosis (a valuable long article by D r Paul ~Vood reprinted from the British 2~redical Journal) to chronic bronchitis, benign and malignant lung tumours, tuberculosis and sarcoidosis. The articles are of good scientific quality, the book is well printed and the illustrations are excellent. It must cost considerably more to produce than the I5S. needed to buy it.
Pulmonary Circulation and Respiratory Function A Symposium held at Queen's College, Dundee; University of St. Andrews. I956. Distributed by E. and S. Livingstone, Edinburgh. Pp. 44. 12s. 6d. This small book contains abstracts of papers on the pulmonary circulation and respiratory function presented at a symposium in September i955. T h e y are commendably brief and informative, covering a wide range of subjects, from the collateral circulation of the l u n g - by Dr Averill Liebow, Professor o f Pathology of Yale University and Praelector in Pathology at the University of St Andrews for I955 pulmonary vasomotor nerve activity, and control mechanisms in the right ventricle to pulmonary function in the newborn lamb, gas diffusion and breathing machines. T h e contributions to the discussion are equally informative; but they are somewhat unevenly reported and here and there unnecessarily long.

There are few good textbooks dealing with tuberculosis as a general infectious disease rather than the disorder of a single system. There are fewer still that arc concerned only with tlle disease in children and adolescents. T h e revised Second edition of this book may, therefore, be a useful reference work to specialists Of several specialties, for it contains much information in all branches of the subject.
LETTER

THE
EDITOR
MASS R A D I O G R A P H Y Sir, - T h e imminent visit of the mass radiography unit to this area prompts me to draw attention to some criticisms of mass radiography from the point of view of an area chest physician, which I feel are worth recording.
Inability to provide an adequate service.- With a total annual examination rate of approximately three million it is quite obvious that the diagnostic screen can only he very imperfect. In m y own area the mass miniature radiography unit has so far paid only two visits as follows: during x949 in a four-week survey 8,6oo persons were x-rayed, being 22 per cent of the adult population; during i953 in a two-week survey 4,9oo persons were x-rayed - 12.5 p e r c e n t of the adult population. Mass radiography cannot, therefore, be said to have contributed much to the early diagnosis of chest disease in this area.
