The pioneer work on the science of metallurgy. Parts of it were pub
lished nearly a hundred years before this book was printed. But this
edition has the advantage in completeness and elaborate illustration.
Curious pictures, showing the ancient methods of managing ores, are
on almost every page. Pittsburgh metallurgists will be interested in

observing how many of the old processes are still in use, and how
others have been changed or superseded.
