276 logy and mechanisms are properly presented with the help of many clear and suitable photos and drawings. The second half of the book concerned with corrosion control reveals the same positive aspects as the previous one, and is even more interesting from the stand point of the design engineer, metal user, metal finisher and student of engineering. The author stresses the importance of basic design, choice of metal, metal coupling, surface treatments, weldings, joints, stress and fatigue, as deeply concerned with the corrosion behaviour of a metallic construction. Inhibition, cathodic and anodic protection are well presented too, even if possibly in a rather short form. Corrosion protection by surface coatings is fully treated, with the usual skillful employment of diagrams and photographs. The final two chapters cover corrosion testing, Pourbaix diagrams and tables on corrosion resistence of metals. A more detailed treatment of the modern electrochemical methods of corrosion testing, including some notices on instrumentation might possibly be useful. In conclusion, this is a very attractive, clear and complete textbook for students of engineering, but it provides too an easily readable guide for anyone who wishes to have an outline of technical possibilities in corrosion prevention.

Principi di Ceramurgia e Tecnologia Ceramica (in ital.). By G. Aliprandi, E.C.I.G. Ed., Genova, 1975, pp. 1285, Lit. 30,000. The Editor ECIG has recently published the book "Principles of Ceramurgy and Ceramic Technology" by Prof. Giovanni Aliprandi. Prof. Aliprandi has availed himself for some of the chapters of the co-operation of scholars specializing in the various branches and has coordinated the compilation of the 44 chapters constituting this work.
277 The result is a text of over 1150 pages supplemented with 450 figures and 125 tables which presents the technicians with the fundamental aspects of this science in an organic and systematic way. The text puts particular emphasis on physical chemistry and on the relations between properties and structure of ceramic materials, thus distinguishing itself from already existing treatises on Ceramics. Though it does not claim to present itself as a treatise on advanced ceramic technologies it dedicates ample space to the description of all ceramic products (traditional and non traditional, refractory and non refractory) of interest to the aeronautic, electronic and nuclear industries. We therefore feel that the presentation of this text, wich is new to many markets, will meet with the greatest interest from all those who for professional reasons wish to widen their knowledge of the fundamental aspects of this matter.
