Abstract
THE chemistry of the cyanogen compounds is one of the more difficult branches of the subject, and is one on which it is not easy to find collected information. The first edition of this book, published in 1915, served a very useful purpose in bringing together a large amount of information in a systematic form, and the new edition is necessary in view of the work which has appeared since that time. The treatment is practical, scarcely any space being given to theory, and in some cases this is a real defect of the book. The only formula for Prussian Blue is an old one which is incorrect, no notice being taken of recent work in this field which has cleared up much obscurity. Many of the formulse given in all parts of the book are semi-empirical, and some account should have been taken of modern co-ordination formulae for the compounds.
