The reader is taken rough the whole spectrum of effects, )m the gross disturbances of growth d development through the reactions cells and cell systems down to the Dlecular level, where the ultimate iturbances of enzyme systems are itically surveyed. Aspects of suscepti-lity and of selectivity are thoroughly "ted in three chapters which include nsiderations of the factors intrinsic to e plant and also those arising from rmulation and the techniques of )plication. The book ends by looking herbicide design, its past and present id its promise for the future.

Volume I. February 1963, 384 pp., 70s.
While research in the classical fields of botany continues to be prosecuted with vigour, application of the most modern principles and techniques in the physical sciences to the study of plants is also proceeding at an ever-increasing pace. The danger therefore now exists of a dichotomy in botanical research with neither branch able to assimilate the findings of the other and with a resulting lack of the vitally necessary integration, particularly since original and important papers are scattered over a wide range of journals with no immediate impact on standard textbooks.
It is the aim of the present, and the future volumes of Advances in Botanical Research to satisfy the clear need for readily available, up-to-the-minute authoritative statements on the advances being made both in the classical and the modern fields of research. This new serial publication differs from others in that the articles included are not in the main reviews but represent assessments, by recognized authorities, of their own work against the background of relevant work in progress in other laboratories.

VOLUME 1. PRINCIPLES, METHODS, and GENERAL APPLICATIONS
September 1963, 63 7 pp., 171 s. 6d.
Subscription price 150s. Valid on orders for the complete set received before publication of the last volume.
Volume 1 is divided into three sections which provide a comprehensive coverage of the present methods for the analysis of pesticides and food additives. The first section, devoted to principles, covers formulation analysis, residue analysis, analyses of intentional and incidental food additives, extraction and clean-up procedures, and toxicological testing methods. The second section presents general methods for which the contributors have selected examples from the fields of pesticides and food additives. The final section deals with general applications, including residue analysis in the food and dairy industries, pesticide analysis in meat products, and residue analysis in government laboratories.
