(when the whole of the blade and protrusion is visible). The jaws of the extractor are positioned over the blade with the jaw marked " Top " towards the operator and the jaws closed, trapping the blade between them and bending it slightly. The handle is then easily pulled away. The slight bending does not damage the blade and the tool may be used to insert a new blade. In practice, no member of staff has found any difficulty in using the device; only seconds are required to learn how to align the blade and extractor. With left-handed operators the holder must be turned upside down. Fig. 1—Extractor for scalpel blades.

surfaces are curved so that when the blade is gripped between them it is bent and the end of the slotted protrusion is lifted clear of the shoulder on the holder (fig. 2). To remove a blade, the scalpel is held in one hand with the shoulder of the handle extension towards the operator

THIS is the second textbook on psediatric gastroenterology in the English language, and its comprehensiveness makes it an important contribution to a specialty which deserves much wider recognition. It is intended as a reference book for paediatricians and for those making a special study of gastroenterology in children. All the contributors, who come from many parts of the world, put across their vast experience of the subjects discussed. This applies especially to the chapters on the exocrine pancreas, absorption and malabsorption through the small intestine, the radiology of the gastrointestinal tract, and gastroenterological problems in children of developing countries. Perhaps less helpful to the clinician is the chapter on the liver and biliary system, where the diagnostic problems are inadequately discussed. Notable by its absence is a chapter of its own on the development of immunological mechanisms in the gut and gastrointestinal immunological abnormalities relating to disease of the bowel. This is a valuable book for every doctor interested in pasdiatric problems, especially since it contains a comprehensive reference system for those who wish to pursue the individual subjects to appear

more

fully.

A Handbook of

Community Medicine

Edited by A. M. NELSON, F.F.C.M., Kingston and Richmond Area Health Authority. Bristol: Wright. 1975. Pp. 354. S8.

THIS is a multiple-author addition to the rapidly growing number of books on community medicine; the contributors are from both the N.H.S. and the academic branches of the specialty. Several chapters are good. The first, on Education for Community Medicine, highlights the sins of omission in the curricula of many medical schools, and would be profitable reading for medical teachers and their students. The last chapter is on Interface Problems in Community Health and is concerned with the changes which have led to the reorganistion of the National Health Service and some of the difficulties that have resulted. As a whole

Requests for reprints should be addressed to J. McK., West of Scotland Health Boards, Department of Clinical Physics and Bio-Engineering, 11 West Graham Street, Glasgow G4 9LF. Inquiries regarding supplies of this device should be addressed direct to Eschmann Brothers and Walsh, 24 Church Street, Shoreham-by-Sea, Sussex. The device is protected by British patent application (No. 4170/72) and U.S. patent

application (No. 326150). the book suffers from a lack of cohesion-seemingly several disparate topics have been brought together under the asgis of community medicine but a definitive structure does not emerge. It is difficult to see why the two appendices are so designated; certainly that on Organisational Development and Management has as much right to the central text as several of the other selected topics. Repetitiveness is also a fault; although health education, screening, data and information systems, and vital statistics are welldocumented topics meriting chapters of their own, the same material is unnecessarily incorporated in other sections to the detriment of the book as a whole. The readership aimed at is all-encompassing-medical students, general practitioners, consultants, and members of other healthcare professions. With this in mind, the book is rather expensive for what is offers. Book of Child Care HUGH 1975.

JOLLY, F.R.C.P. London: George Allen & Unwin. Pp. 620. E6.50.

Dr Jolly’s new book, both in size and style, is reminiscent of Mrs Beeton’s Household Management-though none the worse for that, and it may well prove just as popular. It is amazingly comprehensive in its coverage, even down to how to dry a pram after rain. Some chapters one feels must have been written by a woman, and although’Dr Jolly acknowledges a " great Debt " to a Mrs Anderson, she has no attribution in the authorship, so that one is lost in admiration for Dr Jolly’s knowledge of things not normally thought of as in the area covered by a male paediatrician. The content and advice on the care of children is unexceptionable, being neither absurdly avant garde, nor outrageously reactionary, and few will wish to quibble with the views expressed, though sometimes a problem is stated but no answer is given. In future editions some items may need revision-amongst them breath-holding attacks with no mention of convulsions. It is surprising to find dried milks dismissed as either half-cream or full-cream, when the contributions of the various high and low solute feeds is being so much talked about by paediatricians. Nevertheless, this book can be confidently recommended to any parent, in the sure knowledge that it will produce neither hippies nor drop-outs nor reactionaries-though equally it cannot be guaranteed to prevent such

happenings.
