GRIFFIN'S METALLURGICAL SERIES. THE METALLURGY OF GOLD BY T. KIRKE ROSE, D.Sc., A.R.S.M., F.C.S., SECOND EDITION, Nearly Ready. Large 8vo, Handsome Cloth, Illustrated. LEADING FEATURES. 1. Adapted for all who are interested in the Gold Mining Industry, being free from technicalities as far as possible; of special value to those engaged in the industry-viz., mill-managers, reduction-officers, &c. 2. The whole ground implied by the term "Metallurgy of Gold" has been -covered with equal care; the space is carefully apportioned to the various branches of the subject, according to their relative importance. 3. The MACARTHUR-FORREST CYANIDE PROCESS is fully described for the first time. By this process over £2,000,000 of gold per annum (at the rate of) is now being extracted, or nearly one-tenth of the total world's production. The process, introduced in 1887, has only had short newspaper accounts given of it previously. The chapters have been submitted to, and revised by, Mr. MacArthur, and so freed from all possible inaccuracies. 4. Among other new processes not previously described in a text-book are(1) The modern barrel chlorination process, practised with great success in Dakota, where the Black Hills district is undergoing rapid development owing to its introduction. (2) New processes for separating gold from silver-viz., the new Gutzkow process, and the Electrolytic process; the cost of separation is reduced by them by one-half. 5. A new feature is the description of EXACT METHODS employed in particular extraction works-Stamp-batteries of South Africa, Australia, New Zealand, California, Colorado, and Dakota; Chlorination works also, in many parts of the world; Cyanide works of S. Africa and New Zealand. These accounts are of special value to practical men. 6. The bibliography is the first made since 1882. "Dr. Rose gained his experience in the Western States of America, but he has secured details of gold-working from ALL PARTS of the world, and these should be of GREAT SERVICE to practical men. The four chapters on Chlorination, written from the point of view alike of the practical man and the chemist, TEEM WITH CONSIDERATIONS HithertO UNRECOGYISED, and constitute an addition to the literature of Metallurgy, which will prove to be of classical value."—Nature.

Showing at a glance the MUTUAL CONVERSION of MEASUREMENTS in DIFFERENT UNITS Of Lengths, Areas, Volumes, Weights, Stresses, Densities, Quantities of Work, Horse Powers, Temperatures, &c. For the use of Engineers, Surveyors, Architects, and Contractors. BY ROBERT HENRY SMITH, M. INST. MECH. ENG., *Prof. SMITH'S CONVERSION-TABLES form the most unique and comprehensive collection ever placed before the profession. By their use much time and labour will be saved, and the chances of error in calculation diminished. It is believed that henceforth no Engineer's Office will be considered complete without them. The SUPERIORITY of the GRAPHIC METHOD is shown by the following considerations - 1. It is CONTINUOUS-that is, there is no break or gap between any one quantity and the next higher or lower quantity convertible by means of diagrams. 2. The Tables are completely RECIPROCAL. By means of the same table conversions in both directions, from English to French and French to English, are equally possible. 3. Conversion by the Graphic Table is found by experience to be MORE RAPID and LESS FATIGUING to the eye and brain. 4. After one becomes accustomed to the general method, the Graphic Diagram has the advantage of giving to the eye a pictorial representation of the RELATION BETWEEN the TWO SETS of MAGNITUDES compared. This is not a simply sentimental or ideal advantage. It has REAL PRACTICAL UTILITY, because it prevents possibilities of gross error. "The work is INVALUABLE."-Colliery Guardian. "Ought to be in EVERY office where even occasional conversions are required. SMITH'S TABLES form very EXCELLENT CHECKS on results... set of diagrams."-Electrical Review. Prof. A VERY USEFUL and good "Prof. Smith deserves the hearty thanks, not only of the ENGINEER, but of the COMMERCIAL WORLD, for having smoothed the way for the ADOPTION of the METRIC SYSTEM of MEASUREMENT, a subject which is now assuming great importance as factor in maintaining our HOLD upon FOREIGN TRADE. There can be no doubt that the antiquated system of Weights and Measures used in this country is doomed to be superseded by the much simpler method of DECIMAL MEASUREMENT. The sooner this is recognised, the better." ."-The Machinery Market. LONDON: EXETER STREET, STRAND. |
