3. A Dictionary of Applied Chemistry ; by Sir Edward 

 Thorpe, Assisted by eminent Contributors. Revised and 

 Enlarged Edition in Five Volumes. Vol. V. 8vo, pp. 830. 

 London, 1913 (Longmans, Green and Co. Price, $13.50 net per 

 volume). — It is a matter of satisfaction to notice that the publica- 

 tion of this great work of reference has been completed within 

 two calendar years, so that the whole work, of recent date, is now 

 available for use. There is no doubt that this dictionary is of 

 the greatest importance and value, and that it is essential to the 

 equipment of all libraries where reference to chemical topics is 

 demanded. The present volume contains many interesting 

 articles, such as those on sodium, spectrum analysis, starch, sugar, 

 sulphur, sulphuric acid, synthetic drugs, tannins, vegeto-alkaloids, 

 water, destructive distillation of wood, and many others. The 

 modern treatment of the subjects is illustrated by an excellent 

 account, under sulphur, of the Trasch method of mining this 

 substance as practiced in Louisiana, and in general, throughout 

 the whole work, the topics appear to be ably treated from the 

 most recent point of view. h. l. w. 



4. Attends Commercial Organic Analysis / Fourth Edition, 

 entirely rewritten, edited by W. A. Davis and Samuel S. 

 Sadtler. Vol. VIII. 8vo, pp. 696. Philadelphia, 1913 (P. 

 Blakiston's Son & Co. Price 85.00 net). — This is the last volume 

 of this important work, but it is proposed to issue at a later date 

 a supplementary volume containing a complete reference index 

 of the whole work, and including also such additions as are 

 needed to bring the work up to date. 



The present volume deals with enzymes, proteins and albumi- 

 noid substances, milk and milk products, meat and meat products, 

 haemoglobin and blood, proteoids, fibroids. This volume con- 

 tains much valuable information for those who are interested in 

 the chemistry of foods, and the whole work is a most important 

 and useful addition to the literature of industrial analysis.

5. Chemistry, Inorganic and Organic ; by Charles Loudon 

 Bloxam. Tenth Edition, rewritten and revised by Arthur G. 

 Bloxam and S. Judd Lewis. Large 8vo, pp. 878. Philadel- 

 phia, 1913 (P. Blakiston's Son & Co. Price $5.00 net).— The 

 first edition of this work appeared in 1867. The editors of the 

 present edition have endeavored to maintain the reputation of 

 the book as the most compendious work on chemistry in a single 

 volume, and it appears that they have very successfully carried 

 out this aim. The book is intended for students of chemistry as 

 well as for those professionally interested in the science. It 

 gives a very full account of modern chemical facts and theories, 

 and it describes and illustrates many important experiments. It 

 is extensive enough to serve well as a book of reference in con-
