The several editions of Professor Rudolph Wagner's *' Handbuch der 



Chemise hen Technologies^ 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, Bismuth, Zinc, 

 Zinc Salts, Cadmium, Antimony, Arsenic, Mercury, Platinum, Silver, Gold, Man- 

 ganates, Aluminum, and Magnesium, are described. The various applicat'ons of the 

 Voltaic Current to Electro-Metallurgy follow under this division. The Preparation of 

 Potash and Soda Salts, the Manufacture of Sulphuric Acid, and the Recovery of Sul- 

 phur from Soda- Waste, of course occupy prominent 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 

 preparation 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 Preser- 

 vation 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 prepa- 

 ration of Sugar from Beetroots. 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 the Materials for Dyeing has 

 necessarily required much space ; while the final sections of the book have been de- 

 voted to the Technology of Heating and Illumination.
