Excerpt from A Treatise on Brasses, Bronzes, and Other Alloys, and Their Constituent Metals, Vol. 3: Materials of Engineering The Author and the Publishers of this work have been agreeably surprised to find that the sale of the several vol umes of the treatise has been such as to compel the publica tion of, now, three editions of the part which, it was at the first supposed, would find least demand. They take the opportunity, while issuing this revised edition, to express gratification arid appreciation. The work has apparently come to be accepted as standard, and it has become their duty to see that it is kept fully up to the requirements of the profession of engineering, and of those architects and those metallurgists who find a place for it in their libraries and on the list of their reference books. The present edition has been improved by the correction of every error as yet discovered by the writer, the publishers or the readers, both professional and critical; many of whom have taken much trouble to comply with the request printed in the inserted slip, which will be found in every copy, asking for such aid. It has also been given greater value, it is thought. By the introduction of much new matter in the body of the work, under appropriate heads, and by the extension of the appendix where will be found some valuable matter relating to recent discoveries and developments in the metal lurgy of the rarer of the useful metals, such as aluminium and magnesium, and their alloys.
