outcome of various forms of treatment. This chapter now contains 45 illustrations and 22 tables where before there were 19 illustrations and 9 tables.

The emphasis in each chapter is on the correlation of clinical and pathological findings. Of particular value are the line drawings showing the sites of election for different growths, and the lymphatic spread.

Only praise can be given to the author for this unique textbook, for it is an outstanding contribution to the world literature of tumours of the head and neck. The book is well written and the material is logically presented and as a consequence it is easy to read. This book is written for all pathologists, surgeons and radiotherapists with a special interest in head and neck turnours, most of whom will already have skills and at least some knowledge of the treatments described. However, the book will be invaluable to those starting their training in this field as well as the non-specialist. There is so much to applaud and so little to dispute in this scholarly work for what to many is a complex subject.

DIAGNOSTIC ELECTRON MICROSCOPY. Vol. 2. First Edition.

Edited by BENJAMIN F. TRUMP and RAYMOND T. JONES. Pp. xiii + 40x. (New York: John Wiley & Sons, 1979.) Price jcI42.

This volume deals with the role of the electron microscope as a diagnostic tool in pathology. It begins with a description of the programme of diagnostic electron microscopy (EM) established

by the Veterans A~inistm~on (VA) in the U.S.A. outlining its organisation, goals, performance criteria and giving a summ~ of the experience of the VA in using the electron microscope routinely.

The second chapter is concerned with the ultms~ctur~ pathology of the liver and those areas where the electron microscope can most usefully be employed. The most important fields of study would appear to be the identification of infectious agents in the liver, the identification of cell type and origin, the evalua- tion of liver response to drugs, the diagnosis of deposit and storage diseases and the correlation between a given liver disease and changes in hepatocyte organelles.

The book continues with a chapter on the hematopoietic system, the first half dealing with the ultra- structural features of the 3 major hematopoietic cell lines, erythrocytes, granulocytes and mega- karyocytes, the second with lymphoreticular cells.

The next 3 chapters are concerned with the use of the electron microscope in ophthalmic path- ology, the pathology of the bladder and in gynaecology. Having a particular interest in ophthalmic pathology the reviewer found this chapter of great interest and in one case directly helpful in identification and interpretation.

The last 2 chapters deal with ultrastructural changes of peripheral nerve and diagnosis of central nervous system disorders by transmission EM.

Most of the work described in this volume has in fact been done using transmission EM, a measure of the state of the art at the moment. One would hope that future volumes will see the routine use of such techniques as X-ray and energy loss analysis to enable quantitative statements to be made about specimens in the electron microscope. important information.

For the moment, this volume is a useful presentation of much

This is the 24th yearbook of the Society for Jaw and Face Surgery in Germany and it maintains the very high standard of the previous volumes. correction of contour defects in the face.

Like them, it has a theme and on this occasion the theme was the This of course encompasses many topics from nasal deformities

to prominent ears and there is a wealth of material to be found in its pages. The earlier yearbooks had summaries at the end of the papers in English, French and Spanish but

these have now been dropped and the book is only of value to those who can understand German, although much may be gleaned from the illustrations.
