"This work is of the highest technical character, and gives not only a full and practical ac- 

 count of the raw materials and manufacture of glues, gelatines and similar substances, hut 

 gives many hints and information on the use of such substances in veneering, carpentry and 

 many other purposes. Many tests are given for glue in different stages of the progress of its 

 manufacture, and the commercial value of a commodity so much in general use is exemplified 

 by statistics and figures, it is certainly a valuable treatise upon an article for which very 

 little literature in any form has previously been obtainable." Carpenter and Builder. 



" Books on the art of glue making are more than usually scarce, and users of that article, 

 as well as those who may be tempted to embark in the industry, should therefore welcome 

 this book by Dr. Samuel Rideal. a Fellow of the Institute of Chemistry, and a leading authority. 

 In this book he has collected the more important facts connected with the manufacture of glue 

 and allied products, and stated the experience he has gained in examining various commercial 

 samples during the past ten years. ... Dr. Kideal's book must be regarded as a valuable con- 

 tribution to other technical literature, which manufacturers, merchants and users may study 

 with profit." British Trade Journal. 



"This volume is the latest addition to the excellent series of special technical works for 

 manufacturers and professional and commercial men issued by the well-known publishers of 

 The Oil and Cdlourtnah's Journal. The volume in every way fully maintains the high standard 

 of excellence of the whole series, and deals with the subject of glue making and glut; testing in 

 a thoroughly exhaustive manner. Chapters are given on the constitution and properties, and 

 raw material and manufacture, and of the uses of glue, and in this latter respect it will doubtles-, 

 be information to many readers to learn to what extent glue enters into the manufacture of 

 many commercial products not apparently associated with glue. Exhaustive chapters on the 

 processes and methods of glue testing, and on its commercial aspects, complete this useful and 

 most carefully prepared volume," Carriage Builders' Journal.
