A Manual of Paper Chromatography and Paper Electrophoresis provides a comprehensive discussion of the techniques of paper chromatography and paper electrophoresis. The book is organized into two parts. Part I on paper chromatography provides a readily accessible source for some of the many uses and adaptations of paper chromatography.

Part II on paper electrophoresis discusses basic principles and methodology. The emphasis throughout has been on the separation of protein mixtures, particularly blood serum. This reflects the fact that it is in this particular application that paper electrophoresis has thus far not been challenged by paper chromatography, whereas many of the smaller molecules can be resolved equally well or better by the thus far more widely employed chromatographic procedures.

The object of'Residue Reviews'is to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of residues of pesticide and certain other chemicals in foods, feeds, and in transformed food products. During the 144th National Meetings of the American Chemical Society in Los Angeles, California the Pesticides Subdivision of the A. C. S. Division of Agricultural and Food Chemistry on April 1, 1963 sponsored a symposium'Instrumen­ tation for the Detection and Determination of Pesticides and Their Residues in Foods'. With special permission from R. N. HADER and his associates in the American Chemical Society, that symposium is reproduced in this volume of'Residue Reviews'because of its timeliness and significance to pesticide residue analysts everywhere. Without exception the symposium authors accepted my invitation to utilize'Residue Reviews'as their publication medium, and their coopera­ tion in the extra chore of providing manuscripts conforming to the style requirements of'Residue Reviews'is gratefully acknowledged. Presiding over the two sessions of the symposium were CHARLES L. DUNN and MILTON S. SCHECHTER, whose introductory remarks at that time comprise the foreword to this volume; their enthusiastic assistance both in organizing the symposium and in achieving this final product is warmly appreciated.

The Chemistry and Technology of Edible Oils and Fats contains the proceedings of a conference arranged by Unilever Limited and held at Port Sunlight in England on March 10-12, 1959. The papers explore the chemistry and technology of edible oils and fats, with emphasis on analytical procedures, the methods of industrial processing, and the pattern of dietary fat consumption seen from the viewpoint of the economist. This book is comprised of seven chapters and opens with a discussion on the physical and chemical properties of the constituents of edible oils and fats, with particular reference to the fatty acids, the glycerides, and those closely related compounds which are fatty in a general sense. The following chapters focus on the pattern of fatty food consumption in the United Kingdom; the methods used for the analysis of oils and fats; processing of oils and fats for edible purposes; the use of the isotopic dilution technique in the determination of linoleic acid; and the application of gas/liquid chromatography to the analysis of atheromatous plaques. The final chapter deals with the use of spectroscopic and X-ray techniques in the analysis of oils and fats. This monograph will be a useful resource for chemists and food technologists.

Surface Chemistry presents the proceedings of the Second Scandinavian Symposium on Surface Activity, held in Stockholm, Sweden on November 18–19, 1964. This book discusses the important applications of surface chemistry in many problems of both fundamental and applied research. Organized into 25 chapters, this compilation of papers begins with an overview of the adsorption of mixed collector systems onto minerals chosen for their different surface energies. This text then describes the bonding of amine to the reactive residual matter on the mineral surface. Other chapters consider the solubilities of some 30 hormonal steroids in aqueous solutions of three association colloids of various types. This book discusses as well the relationships between chemical structure and biological degradation of surfactants. The final chapter deals with several properties of aqueous emulsions and of foam, which are determined by the stability of thin aqueous films against rupture. This book is a valuable resource for chemists.

The Collected Works of Irving Langmuir, Volume 11: Cloud Nucleation presents the papers written by Dr. Irving Langmuir on the study of artificial nucleation of clouds to produce precipitation. The compilation provides the study of every possible aspect of cloud and weather modification. This volume contains chapters that are devoted to the discussion of such subjects as the nucleation of clouds with dry ice; the analysis of photographic data showing the effects produced by supercooled clouds with ice nuclei; the production of rain by a chain reaction in cumulus clouds at temperatures above freezing; nucleation of clouds with silver iodide; and basic discoveries underlying weather modification. Meteorologists will find the book interesting and invaluable.

Electrochemistry is a collection of papers presented at the First Australian Conference on Electrochemistry, held in Sydney on February 13-15 and in Hobart on February 18-20, 1963, jointly sponsored by The Royal Australian Chemical Institute, The University of New South Wales, and The University of Tasmania. This conference highlights the numerous advances in the field of electrochemistry. This book is organized into 12 parts encompassing 70 chapters. The first parts deal with the solid-state reactions and processes in electrochemistry; the thermodynamic aspects of electrolytes; and the role of electrodic in corrosion control. The succeeding parts explore the concepts of equilibrium and non-equilibrium theory of double layers, as well as the various electroanalytical methods used in electrochemistry, including polarography, potentiometry, and coulometry. Other parts consider the areas of application of electrochemistry, such as in electroplating, anodizing, fuel cell, electrowinning, and electrorefining. The remaining chapters are devoted to non-aqueous electrolytes, molten salts, and electrode and electrochemical processes. Electrochemists and physicists will find this book invaluable.

Medicine and Natural Sciences: Chemistry in Botanical Classification contains the proceedings of the Twenty-Fifth Nobel Symposium held in Sodergarn, Sweden, on August 20-25, 1973. The papers explore the chemical approach to plant classification and cover topics ranging from chemosystematics and applications of special classes of compounds to insects and plant chemotaxonomy. Biosynthetic pathways in chemical phylogeny and some aspects of organic geochemistry are also discussed. This book is comprised of 32 chapters divided into five sections. The first chapter provides an overview of the chemical approach to botanical classification, with special reference to the higher taxa of Magnoliophyta. The reader is then introduced to chemosystematics and the construction of phylogenetic schemes, as well as the use of a chemical character for the classification of living organisms. The following chapters focus on The chemistry of disjunct taxa; homology of biosynthetic routes; and applications of special classes of compounds such as flavonoids. The systematic distribution of ellagitannins in relation to the phylogeny and classification of the angiosperms is also considered. The final chapter describes phytochemical and biological procedures for screening of plant materials. This monograph will be of value to botanists, plant taxonomists, and chemists.
