LONDON: CHARLES GRIFFIN AND COMPANY, Limited, EXETER STREET, STRAND. 1904.
The continued popularity of the present work, the last edition of which was published only a little over a year ago, continues to be a source of gratification to the publishers, who have much pleasure in issuing the present edition.
January 1904.
The principal changes in this edition are additions to the articles on Gold, Cyanides, and Nickel, and a much enlarged Index. The additional matter covers more than forty pages.
J. J. BERINGER. Camborne, January 1900.
The Text-book now offered to the public has been prepared to meet the existing want of a practical handy book for the Assayer.
To mining men the word assaying conveys a sufficiently clear meaning, but it is difficult to define. Some writers limit it to the determination of silver and gold, and others imagine that it has only to do with furnace-work. These limitations are not recognised in practice. In fact, assaying is becoming wider in its scope, and the distinction between assayers and analysts will in time be difficult to detect. We have endeavoured rather to give what will be of use to the assayer than to cover the ground within the limits of a faulty definition.
