in water and are at pains to avoid overlap with the previous review. The section dealing with the preparation and characterisation of dispersions contains interesting material_ The exact terminology of the section dealing with surface area determinations might be questioned. It is in fact the solid particles together with the water which form the hydrosol, but it is the surface area of the solid particles which is measured. The main problem with small particles is that aggregation may cause errors in the determination of the area. However, the effect of lowering the temperature of the solid down to that of liquid nitrogen - the temperature at which many of the surface area determinations are made - has very seldom been questioned. Other important sections in this review deal with electronkinetics, the charge and potential distribution at the solid/solution interface, colloid stability and the rheology of colloidal dispersions. A short review by P. Ekwall and P. Stenius deals with Aggregation in Surfactant Systems. This is divided into various sections, as follows: the thermodynamic treatment of surfactant aggregation, surfactants in aqueous solutions, liquid crystalline phases and solutions of surfactants in anhydrous non-polar solvents. A final review by P. Becher deals with Emulsions and has a short section dealing with applications of emulsions which could profitably have been developed further. D. D. IUPAC Analytical Chemistry, Vol. 4 (Kyoto 1972), edited by Mitsugi-Senda, Butterworths, London, 1973, pp- 170, price $5.00. This volume reports the eleven plenary lectures presented at the International Congress on Analytical Chemistry held at Kyoto, Japan in April 1972. Obviously, such a conference sponsored by IUPAC in conjunction with the Science Council of Japan attracted many of the “big guns” of analytical chemistry. The plenary lectures do not reflect completely the major growth areas in analytical chemistry, but they do include some of the areas and problems which are of current interest. The analytical problems associated with the environment and trace analysis receive the main attention, and the five lectures associated with these problems are worthwhile reading for all chemists, especially for those who constantly require the analytical chemist to give them answers beyond the capabilities of current techniques. The other lectures deal with some of the more detailed aspects of presentday chemistry. These include a detailed review of precipitate-based ionselective electrodes, and two dealing with organic ligands and chelates. The opening lecture was naturally a review of Analytical Chemistry in Japan, delivered by Somiya; it is useful to have such information; with so much work being carried out and published in what used to be a minor scientific,language, an awareness of the breadth of study and activity can do much to foster the concepts of international exchange of ideas.

The reader will find chapters with the following titles: B&c theory of the electronic states of molecules, ~troduc~on to the linearly polarized electronic spectra of inorganic crystals, A chemist’s guide to the band theory of solids, Vibrations-elec~unic interaefions, Int~rconfi~ati~n~ and charge transfer transitions, Theory of magnetic circular dic~oism (Magi spe~~oscopy, The technique of MCD, Applications of MCD to charge transfer and ligad field spectra, MCD spectra of charge transitions: octahedral Ir4”, MCD spectroscopy of matrix isolated species, ~~~~1~1~ polarised emission spectroscopy, Photoelec~o~ spectroscopy and allied techniques: general introduction, UV photoelec~~~ spectroscopy of mofeoules in the gas phase, UV photoeiectron spectroscopy of transition metal compounds, Valence level photo~le~~o~ spectra f XPS and UPS) of solids and interfaces, ~ultiplet splitting in the X-ray photoemission spectra.of open-shelf ions, X-ray photoemission from core electrons in solids, Techniques related to photoelectron spec~os~opy~ X-ray spectroscopy, The use of inelastic neutron scattering to de~rm~e the ~ectro~i~ states of inorganic materials. The ~ont~butions have been written by well-known specialists in the different fields and are all up to date, The book also contains chapters on basic principles such as electronic spectra of inorganic crystals and vibronie gumptions as well as modern tech~ques - impo~~t for the study of electronic states. The aim of the editor to publish a text book rather than a set of proceedings is justified. No scientist working in the field of electronic structure of inorganic compounds should overlook this book.
