Abstract
IN order to make up the lee-way developed during a period of 7-13 years, two additional volumes are being provided as supplements to the original seven volumes of Thorpe's “Dictionary of Applied Chemistry”. The present volume of about 700 pages is issued at the same price as the original volumes and covers the literature from A to M. Since the list of contributors to the new volume occupies five pages, an individual review of the articles which they have written is scarcely practicable; but the reader naturally turns at once to a 20-page supplement to the article on carbohydrates in vol. II, by Dr. E. F. Armstrong, to find the new ring-formulae fully de scribed and discussed. On the inorganic side, articles on hafnium and illinium are contributed by Prof. G. T. Morgan, whilst a long supplementary article on hydrogen by Prof. J. R. Partington includes ortho-and para-hydrogen, but was evidently completed at too early a date to include the isotopes discovered in 1933. Recent technical developments are re presented by well-illustrated articles on coal gas and coke manufacture, on explosions and explosives and on iron and steel. A long supplementary article on analysis by Prof. G. T. Morgan is devoted mainly to the organic reagents which now play such an im portant part in the detection and separation of the metals, as well as of certain acid radicals. There are also many brief entries and cross-references which maintain the essential character of the dictionary as a work of reference for unfamiliar, as well as for the more familiar, names and subjects.
