Excerpt from The Metallurgy of Lead and the Desilverization of Base BullionIn.ib7o Dr. Percy published his great work, The Metallurgy of Lead, Including Desilverization and Cupellation, which has become the standard book for England and America, and is also highly esteemed by the Germans and the French, into whose lan guages it has been translated. It contains an exhaustive discus sion of smelting and desilverizing as carried on in the principal European works. During the past twenty years, however, so much that is new has been introduced in American practice that a book embodying the latest improvements seems almost a neces sity for the student. It is the aim of the present work to supply this need. Thus, while European practice is not at all excluded from the book, the main Object has been to make it a guide for Americans, and European methods have been discussed more in connection with their applicability in this country than from any other point of view. In the subject of the blast-furnace, for in stance, only such features have been brought out as seemed useful for America. Reverberatory-furnace practice, on the other hand, which has not made much progress as yet in this country, is given more in the European way, while the ore-hearth treatment follows both English and American methods, which supplement one an~ other. Three classes of readers have been kept in mind - the stu dent, for whose use the ground principles and many definitions are given a prominent place, the metallurgist, who needs minute de tail for his practical operations, and the investigator, who will find in the foot-notes the principal references for the subject in.
