ANALYTICAL CHEMISTRY
The Thermal Properties of Transition Metal Ammine Complexes. Wesley W. Wendlandt, James P. Smith, ix + 235 pages. American Elsevier Publishing Co., Inc., 52 Vanderbilt Ave., New York, Ν. Υ. 10017. 1967. $17. This book is a summary of the authors' work in the last ten years in studying the thermal dissociation of transition metal ammine complexes. The modern thermoanalytical tech niques used were successful, in many cases, in elucidating reaction stoichiometry, structural changes, and reac tion mechanisms involved. Discussion in this volume is limited to those complexes involving metal-tonitrogen bonds only. These consist mainly of metal ammonia, ethylenediamine, pyridine, aliphatic amine com plexes, etc.
Chemical Analysis for Ironfoundries, Selected Methods. 215 pages. George Allen & Unwin, Ltd., Ruskin House, Jfi Museum St., London, W.C.I, England. 1967. 4£s. This volume of selected methods contains procedures recommended by the British Cast Iron Research Asso ciation Methods of Analysis Sub-Com mittee. In 1959 the first part of "Se lected Methods of Analysis of Foundry Materials" appeared. It dealt with pig and cast iron. A separate volume for alloy irons, ferro-alloys, slags, refrac tories, fuels and residual elements was planned. However, changes in the sampling and analysis of pig and cast iron have been so great it was felt wise to prepare this new book covering all types of irons and also ferro-alloys and slags. Analytical methods for refrac tories and fuels, trace and residual ele ments have not been included. As stated in the foreword this is a laboratory manual; no extended theo retical discussions are given. After a brief outline of the chemistry of each method the procedure is presented. The book contains some illustrations and an appendix which includes infor mation on equipment, apparatus, re agents, laboratory techniques, the use of spectrophotometers, laboratory hazards, and a table of atomic weights of some elements.

Pyatnitskii. xv + 22^ pages. Daniel Davey & Co., Inc., 257 Park Ave. S., New York, Ν. Υ. 10010. 1967. $14This is another volume in the series, Analytical Chemistry of the Elements, published by the Academy of Sciences of the U.S.S.R. and translated by the Israel Program of Scientific Transla tions. The book has been translated by N. Kaner and edited by D. Slutzkin. It was originally published in Russia in 1965. Chapter I discusses the chemical analytical characteristics of cobalt and cobalt compounds of importance in analytical chemistry. After this intro duction to the subject, the author covers the detection of cobalt ions and the separation of cobalt from accom panying elements. This is followed by chapters on gravimetric, titrimetric, photometric, polarographic, and other methods for the determination of co balt. Chapter IX, on the determina tion of cobalt in natural and industrial materials covers 36 pages and is di vided into sections dealing with ores, slags, and silicates; steels and ironbase alloys; nonferrous metals and alloys; and soils, plant, animal, and other biological material.
