Abstract
THE first appearance of this book dates hack to 1908, and the edition now brought out contains quite twice as much material as its predecessor. The chapters have increased from sixteen to twenty-one, whilst the subdivisions of chapters, which were so strange in the first edition, are still further elaborated. The new chapters deal prin. cipally with the analysis of ores, refractory materials (acid and basic), fluorspar, lubricating oils, and coal; whilst uranium, cobalt and nitrogen are added to the section on steels. Besides these the chapter on the determination of carbon is amplified considerably, and an interesting account of the estimation of oxygen in tungsten powders and in steels has been inserted. The valuation of nickel chrome steels and Monel metal have been given chapters to themselves. Unfortunately, the new portions (which deal practically entirely with the author's own work the general literature being rather neglected) have been inserted in such a way as to give the book a very patched appearance. The arrangement has also resulted in several rather tiring duplications. A blue pencil wielded by a friendly though very free hand would have tended to a much improved hook. In a work of this nature one naturally looks for all things up to date, and in consequence one is surprised to find no appreciation of the “reductor methods” that are so extremely useful in analysis of this kind. Among many other omissions may be mentioned the work of Gooch and his pupils on vanadium, molybdenum, etc., the recognised volumetric methods for manganese in ferromanganese, the ignition of Brünck's precipitate to nickel oxide, and the iodometric estimation of copper.
