"The literature of corrosion is extensive, but far from satisfactory in its scientific aspects... The writer of the present work has prepared a useful survey of the subject, although confining himself almost exclusively, to work published in English, and without any evidence of first-hand observation... The corrosion of steel boilers and of brass condenser tubes is treated more fully... Here the author is evidently at home, and the chapters on the softening and de-aeration of water, and the protection of boilers by electrolytic methods, are fully illustrated and contain much detail.". - Nature, Sept. 8, 1923.

Somewhat advanced and involves a knowledge of the calculus. Part I deals with the relation between load and stress in the more usual shapes used for structural members, on the assumption that the material is homogeneous and elastic. Part II has to do with the properties peculiar to the materials themselves, with some reference to modes of manufacture; also with testing methods for iron, steel, wire, timber, cement, concrete, brick, stone, and other materials. Chapters on choice of materials and safety factors, life and endurance of materials, and the optical method of showing variation of stress. Authors are lecturers in the College of Technology, Manchester, England.

"More than a mere book... Theory is put forward in a way which not only gets to the bottom of things as far as we know at present, but unravels knotty problems in such a manner that anybody with ordinary intelligence can follow the procedure with ease. great number of tabulated observations by the author and other investigators forms a most valuable, and practically inexhaustible, stock of information... Another feature is that at the end of each important chapter there is a short summary of pros and cons, strictly impartial... The book is full of properlyillustrated tables and curves dealing fully with all the best-known types of gas-producers, and is a compliment to the author and publishers alike." — Harald Nielsen in Gas journal, Aug. 8, 1923.
