This early work on the structure of metals is both expensive and hard to find in its first edition. Its 579 pages contain a wealth of information on the physical properties and chemistry of various metals. This is a fascinating work and is thoroughly recommended for students of metallurgy. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
