✦ Synopsis
considered extremely rare and known only to the mass of chemists by the few brief allusions in text-books. It is not alone the desire for scientific information that has led entirely to the development of the chemistry of these elements but the industrial importance that they have acquired. As might be expected the bulk of the book is devoted to vanadium that has acquired much importance in certain departments of industrial chemistry. Niobium and tantalum are treated together, though special chapters are given to the alloys and compounds of each respectively. Tantalum, it may be mentioned, has recently acquired an important application as a substitute for platinum in certain forms of electrolytic apparatus. Difficulties that arose in the use of this have been to a great extent solved by a Philadelphia chemist, as will be announced through the proper channels in due course. It remains only to say that in this volume we have a comprehensive and complete study of the chemistry of the three elements with an account of their salts and alloys. There is considerable complication in their compounds and many of these are of interest from a theoretical point of view. The analytical methods required for their detection and determination are also presented.
The series is appearing in comparatively small parts and somewhat irregular as to choice of subjects, but in a work of this scope requiring many editors, it is not possible to get all the lines developed in proper order.
