In 1865 the author issued a volume containing reports of one hundred and 

 fourteen cases of Ovariotomy, which was little more than a simple record of 

 fact8. The book was soon out of print, and, though repeatedly asked for a 

 new edition, the author was unable to do more than prepare papers for the 

 Royal Medical and Chirurgical Society, as series after series of a hundred cases 

 accumulated. On the completion of five hundred cases he embodied the results 

 in the present volume, an entirely new work, for the student and practitioner, 

 and trusts it may prove acceptable to them and useful to suffering women. 



" Arrangements have been made for the publication of this volume in Lon- 

 don on the day of its publication in New York." French and German transla- 

 tions are already in press. 



WAGNER 

 A Hand-book of Chemical Tech- 



nology. 



By RUDOLPH WAGNER, Ph. D., 



Professor of Chemical Technology at the University of Wurtzburg. 



Translated and edited, from the eighth G-erman edition, with extensive 



additions, 



By WILLIAM CROOKES, F. R. S. 

 With 336 Illustrations. 1 vol., 8vo. 761 pages. Cloth, $5.00. 



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, Cad- 

 mium, Antimony, Arsenic, Mercury, Platinum, Silver, Gold, Manganates, Aluminum, and 

 Magnesium, are described. The various applications of the Voltaic Current to Electro-Metal- 

 lurgy follow under this division. The preparation of Potash and Soda Salts, the manufacture 

 of Sulphuric Acid, and the recovery of Sulphur from Soda Waste, of course occupy prominent 

 places in the consideration of chemical manufactures. It is difficult to over-estimate the mer- 

 cantile value of Mond's process, as well as the many new and important applications of Bisul- 

 phide of Carbon. The manufacture of Soap will be found to include much detail. The Tech- 

 nology of Glass, Stone-ware, Limes, and Mortars, will present much of interest to the Builder 

 and Engineer. The Technology of Vegetable Fibres has been considered to include the prep- 

 aration 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 Phospho- 

 rus and Animal Charcoal, are considered as belonging to the Technology of Animal Products. 

 The Preparation of Materials for Dyeing has necessarily required much space ; while the final 

 sections of the book have been devoted to the Technology of Heating and Illumination
