PHILLIPS (J.Arthur, M. Inst. C.E., F.C.S., F.G.S.,

Ancien Elève de l'École des Mines, Paris):

ELEMENTS OF METALLURGY: A Practical Treatise on the Art of Extracting Metals from their Ores. With over two hundred Illustrations, many of which have been reduced from Working Drawings. Royal 8vo, 764 pages, cloth, 34/

GENERAL CONTENTS:

I. A TREATISE ON FUELS and REFRACTORY MATERIALS.

II.

A Description of the principal METALLIFEROUS MINERALS, with their DISTRIBUTION.

III. STATISTICS of the amount of each METAL annually produced throughout the World, obtained from official sources, or, where this has not been practicable, from authentic private information.

IV. The METHODS of ASSAYING the different ORES, together with the PROCESSES of METALLURGICAL TREATMENT, comprising: IRON, COBALT, NICKEL, ALUMINIUM, COPPER, TIN, ANTIMONY, ARSENIC, ZINC, MERCURY, BISMUTH, LEAD, Silver, Gold and PLATINUM.

"Elements of Metallurgy' possesses intrinsic merits of the highest degree. Such a work is precisely wanted by the great majority of students and practical workers, and its very compactness is in itself a first-rate recommendation..

.In

our opinion the best work ever written on the subject with a view to its practical treatment."-Westminster Review.

"In this most useful and handsome volume Mr. Phillips has condensed a large amount of valuable practical knowledge......We have not only the results of scientific inquiry most cautiously set forth, but the experiences of a thoroughly practical man, very clearly given."-Athenæum.

"For twenty years the learned author, who might well have retired with honour on account of his acknowledged success and high character as an authority in Metallurgy, has been making notes, both as a Mining Engineer and a practical Metallurgist, and devoting the most valuable portion of his time to the accumulation of materials for this, his Masterpiece. There can be no possible doubt that Elements of Metallurgy' will be eagerly sought for by Students in Science and Art, as well as by Practical Workers in Metals.. Two hundred and fifty pages are devoted exclusively to the Metallurgy of Iron, in which every process of manufacture is treated, and the latest improvements accurately detailed."-Colliery Guardian.

"The value of this work is almost inestimable. There can be no question that the amount of time and labour bestowed on it is enormous......There is certainly no Metallurgical Treatise in the language calculated to prove of such general utility to the Student really seeking sound practical information upon the subject, and none which gives greater evidence of the extensive metallurgical knowledge of its author." -Mining Journal.

THE SURGEON'S POCKET-BOOK: An Essay on the Best Treatment of the Wounded in War; for which a Prize was awarded by Her Majesty the Empress of Germany. Specially adapted to the PUBLIC MEDICAL SERVICES. With numerous Illustrations, 16mo, roan, 7/6.

"Just such a work as has long been wanted, in which men placed in a novel position, can find out quickly what is best to be done. We strongly recommend it to every officer in the Public Medical Services."-Practitioner.

"A complete vade mecum to guide the military surgeon in the field."-British Medical Journal. A surgeon with this Manual in his pocket becomes a man of resource at once."-Westminster Review.

"A capital little book

of the greatest practical value.
