Press Opinions.

"This is a very valuable book, translated from the German, discussing in detail anti-fouling and anti-corrosive paints."—British Mercury.

"Will be of great service to paint manufacturers, engineering contractors, ironfounders, shipbuilders and others."—Engineer and Iron Trades Advertiser.

"The book before us deals with the subject in a manner at once practical and scientific, and is well worthy of the attention of all builders, architects and engineers."—The Builder.

"The book is very readable and full of valuable information, and bearing in mind the importance of the subject treated, it is one which engineers will be well advised to procure at an early date."—Railway Engineer.

"The author goes fully into his subject, and the translator has been successful in reproducing in another language what he has to say. There are given in the text numerous illustrations of the rusting of iron, prepared in the course of a series of personal experiments on the formation of rust."—Journal of Gas Lighting.

"This work is a very elaborate and useful record of the various phenomena in connection with the corrosion of iron and its protection against corrosion.... The book is an exceedingly useful record of what has been done in connection with iron preservation, and will undoubtedly prove to be of much value to railway engineers, shipowners, etc."—Fairplay.

"Herr Andés' book, written purely from a scientific standpoint, will be particularly useful to iron manufacturers, shipbuilders and shipowners.... The book is beautifully printed on good paper, and its appearance does credit to the publishers; the work of translation has been remarkably well done, the language bearing none of those irritating traces of Teutonism which disfigure so many English versions of German technical works."—The Ironmonger.

"This knowledge is conveyed with characteristic German thoroughness in this useful work of Herr Andés, which loses nothing of clearness in Mr. Salter's excellent translation. The causes of rust formation are examined, the proper methods of cleansing the ironwork detailed, and the constitution and application of suitable preventative coverings explained.... The book is a welcome contribution to technological literature, and will be found worthy of the careful study of all who are professionally engaged in the arrangement or superintendence of the class of work dealt with."—Western Daily Mercury.

"The author explains the nature of rust and its formation, and the text is illustrated from about fifty photographs. An immense amount of carefully arranged information follows as to the best methods of applying anti-corrosive substances and the various pigments most efficacious for use under all circumstances. The author has evidently thoroughly investigated and mastered the subject of iron corrosion, its cause and its prevention; and we regard his book as of the greatest importance to bridge-builders and makers and users of structural iron and steel. The book is illustrated throughout and is admirably indexed and arranged."—Iron and Steel Trades Journal.
