Abstract
WE welcome a revised and enlarged edition of this useful work, as the progress of metallurgy is now so rapid and great improvements have been made in smelting during the last decade. A too brief reference has been made to the physical properties of lead and that of its alloys, and much recent work has been overlooked, probably due to the aim of the author in making the work chiefly a compendium of information on lead smelting, which is here brought well up to date. Ore roasting has received the attention it deserves, and we are glad to find that pot roasting is clearly described, and the chemical reactions occurring in this novel process fully discussed, since a correct knowledge of the chemical changes that occur in any process often leads to advancement and discoveries. Useful data are given as to costs in the various modifications developed from the Huntingdon-Heberlein process.
