Kitaigorodsky 133 Corrigenda 164 The Chemical Society London Chemical Society Reviews Chemical Society Reviews appears quarterly and comprises approximately 25 articles (ca. 500 pp) per annum. It is intended that each review article shall be of interest to chemists in general, and not merely to those with a specialist interest in the subject under review.The articles range over the whole of chemistry and its interfaces with other disciplines. Although the majority of articles are intended to be specially commissioned, the Society is always prepared to consider offers of articles for publication. In such cases a short synopsis, rather than the completed article, should be sub- mitted to The Managing Editor, Books and Reviews Section, The Chemical Society, Burlington House, Piccadilly, London, W 1V OBN. Members of the Chemical Society may subscribe to Chemical Society Reviews at E6.00 per annum; they should place their orders on their Annual Subscrip- tion renewal forms in the usual way. Non-members may order Chemical Society Reviews for E16.00 ($33) per annum (remittance with order) from: The Publications Sales Officer, The Chemical Society, Distribution Centre, Blackhorse Road, Letchworth, Herts., SG6 lHN, England. 0Copyright reserved by The Chemical Society 1978 Published by The Chemical Society, Burlington House, London, W1V OBN Printed in England by Eyre & Spottiswoode Ltd, Thanet Press, Margate
