An Important Work for Manufacturers, Chemists, and Students. 



A HAND-BOOK 



OF 



LOGY. 



By RUDOLF WAGNER, Ph. D., 



PROFESSOR OF CHEMICAL TECHNOLOGY AT THE UNIVERSITY OF WURTZBURG. 



Translated and edited, from the eighth German edition, with extensive 



Additions, 



By VI. CROOKES, F. R. S. 

 With 336 Illustrations. 1 vol., 8vo. 761 pages. (Nearly ready.) 



The several editions of Professor Rudolf Wagner's " Handhuch der 



Chemischen Technologie " have succeeded each other so 



rapidly, that no apology is needed in offering 



a translation to the public. 



Under the head of Metallurgic Chemistry, the latest methods of preparing 

 Iron, Cobalt, Nickel, Copper, Copper Salts, Lead and Tin and their Salts, Bis- 

 muth, Zinc, Zinc Salts, Cadmium, Antimony, Arsenic, Mercury, Platinum, Silver, 

 Gold, Manganates, Aluminum, and Magnesium, are described. The various ap- 

 plications of the Voltaic Current to Electro-Metallurgy follow under this divis- 

 ion. The Preparation of Potash and Soda Salts, the Manufacture of Sulphuric 

 Acid, and the Eecovery of Sulphur from Soda-Waste, of course occupy promi- 

 nent places in the consideration of chemical manufactures. It is difficult to 

 over-estimate the mercantile value of Mond's process, as well as the many new 

 and important applications of Bisulphide of Carbon. The manufacture of Soap 

 will be found to include much detail. The Technology of Glass, Stoneware, 

 Limes and Mortars, will present much of interest to the Builder and Engineer. 

 The Technology of Vegetable Fibres has been considered to include the prepa- 

 ration of Flax, Hemp, Cotton, as well as Paper-making; while the applications 

 of Vegetable Products will be found to include Sugar-boiling, "Wine and Beer 

 Brewing, the Distillation of Spirits, the Baking of Bread, the Preparation of 

 Vinegar, the Preservation of "Wood, etc. 



Dr. "Wagner gives much information in reference to the production of Potash 

 from Sugar-residues. The use of Baryta Salts is also fully described, as well as 

 the preparation of Sugar from Beet-roots. Tanning, the Preservation of Meat, 

 Milk, etc., the Preparation of Phosphorus and Animal Charcoal, are considered 

 as belonging to the Technology of Animal Products. The Preparation of tho 

 Materials for Dyeing has necessarily required much space ; while the final sec- 

 tions of the book have been devoted to the Technology of Heating and Illumi- 

 nation.
