unfortunately labelled 15 and 17 respectively (presumably some measure of fluorine content, but this is not stated — the values are too big to be percentages). These are but examples of what could so easily have been avoided. The illustrations cover a remarkably vide field and are well reproduced in good colour. They are usefully informative for those readers who know what to look for and can disentangle such captions as those on p.79 and p.126. A few more commas and full-points would help understanding both of captions and text, but perhaps this is an old-fashioned criticism of the proof-reader. Francis Celoria's style is refreshingly lively, with the ellipsis expected of today's New Yorker' rather than the heavy explanations of nineteenth century 'Punch': the reader must be prepared to do some thinking for himself. Angus McBride's illustration of how NOT to dig (p.121) is delightful and, in fact, full of valuable advice for the over-enthusiastic amateur excavator. There are many wise passages in this book, distilled from the experience of a skilled professional archaeologist. If I seem unduly and adversely critical, it is only because I could have wished it were made even easier to absorb so much of value. Like many paper-backs, the book tends to "come apart at the seams" after a little use, but Hamlyn has done well to produce such an attractive and lavishly-illustrated survey at 40p.
