BOOK

Symposium Ossium. Edited by A. M. JELLIFFE and B. STRtCK- LAND. Edinburgh and London. E. & S. Livingstone. Price, £7.

The European Association of Radiology held a Symposium Ossium in London in April 1968. This volume is the rather long-awaited publication of the proceedings. Perhaps one should declare an interest for I was one of many radiologists who helped in the production of this book. The Editor of our Journal did not regard my modest contribution as sufficient to preclude my reviewing it. The reason will be clear when it is pointed out that the book contains no less than ninety-three papers.

Most of the papers read at the Symposium are included. The great majority originate from Europe. With few exceptions the papers are published in English. In some papers written in Continental languages, summaries in English are included; unfortunately, others have no such summaries.

A wide range of bone conditions is included. Fascinating papers on advances in radiodiagnosis, radiotherapy, radio- biology, anatomy, physiology and pathology of bone wilt be

tbund. One great merit of this book has resulted from the strict limitations of text and illustrations imposed on authors. In my opinion the papers have lost nothing by this con- densation and have gained much by the elimination of the fustian found in so many journals.

The book contains only 339 pages. Within these pages, however, will be found the distillate of practically everything "new in bones". It is invidious to comment on individual papers because so much is governed by one's personal in- terests. In the main the papers are excellent. A few papers are pot boilers, probably submitted in order to defray the lecturer's expenses. Readers will also spot a few familiar papers that have provided their authors with some fruitful meal tickets at previous conferences.

Inclusion of this volume should be obligatory in all radiological libraries, if only because it contains so much new material that will take years to get into the text-books. Since the book will be used for reference, an index at the end would have been useful. At £7 the book is fair value and I would recommend its purchase to colleagues interested in the various aspects of skeletal radiology.
