 AND EVEKY BRANCH OF LEATHER-DRESSING. 



From the French and from original sources. By Campbell 

 MoRFiT, one of the Editors of the "• Encyclopedia of Chemistry," 

 Author of " Chemistry Applied to the Manufacture of Soap and 

 Candles," and other Scientific Treatises. Illustrated with several 

 hundred EngraTings. Complete in One Vol., royal 8vo. (In press.) 



This important treatise will be issued from the press at as early a day as the 

 duties of the editor will permit, and it is believed that in no other branch of 

 applied science could more signal service be rendered to Americart Manufac- 

 turers. 



The publisher is not aware that in any other work heretofore issued in this 

 country, more space has been devoted to this subject than a single chapter ; 

 and in offering this volume to so large and intelligent a class as American 

 Tanners and Leather Dressers, he feels confident of their substantial support 

 and encouragement.
