account of the determination of atom sizes in MnOg based on energy band theory. The final chapter is devoted to a discussion on the nature of the chemical bond in some classes and groups of minerals and contains a clear statement of the author's thesis that ultimately the only satisfactory description of bonding which can be made must be based on the molecular orbital and energy band theories. This concept, in as far as it is currently possible, is then applied to the silicates, beginning with the nature of the chemical bond in SiO 4-, and using data both from X-ray and ESCA spectra. The treatment proceeds in outline to other cation polyhedra in silicates. This is followed by a wide-ranging discussion of the nature of the bonding in sulphides in the context of their energy band structures. The chapter ends with a very brief account of the hydrogen bond. While this book is superficially extremely well produced and will certainly be much used for the data which it contains it is somewhat surprising that the standard of writing and editing is so poor. With a good knowledge of English it is usually possible to guess what the author means and it is perhaps unfair to be too critical in this context. However, the book, in addition, is full of avoidable misprints and it has clearly been very inadequately proof-read. I find if difficult to understand how a publisher, in presenting a book on the international market, and at a very high price, should fail so miserably on the simple matter of spelling.
