and perhaps misleading to cite them. I m u ~ t comment, however, about two paints. First, the author states: "In precise terms, the ideal gas is a limit (as P (pressure) - 0) of a real gas, so that the properties of an ideal gas are the limit- ing properties of real gases (as P -+ O)." This is not true, as can be readily demon- strated with the Jaule-Thomson coefficient. A system is not specified fully in thermo- dynamics by its equation of state. Sec- ondly, Figs. 4 8 and 5-4 are drawn con- fusingly, in that strangely curved trs- jectories are ascribed to free molecular motion.

Grundriss der Chemischen Technik

F. A. Henglein, Technische Hochschule, Karlsruhe. 11th ed. Verlag Chemie, Weinheim, Germany, 1963. xii + 821 pp. Figs. and tables. 19 X 27 cm. 7Y DM.

This exellcent book is probably less known on this continent than in Europe. I t has been translated into Spanish and Russian, and an English translation is in preparation. This is t,he eleventh edition; the first was ~ublished in 1936.

Henglein brings together the vast and diversitied fields of inorganic, organic, biochemical, pharmaceutical and nuclear technology as well as metallurgy and chemicsl engineering. The reader will find interesting chapters on instrumenta- tion, materials of construction, plant design, chemical economics of different countries, chemical education, patent procedures, history of chemical technology as well as fundamentals of thermody- namics and kinetics. There are few suh- jects related to chemical technology that Henglein did not include in his book. Among the interesting topies that will have general appeal m e racket fuels, Xerox process and flotation. The book is therefore, an encyclopedia for the gen- eral reader, an intelligent text for the student and a reference work for the man in industry.

Every chapter is well documented by numerous references to recent literature, a large number of flow sheets, line diagram that are exceptionally clear, pictures from all over the world, and quot,ations from Goethe. The hook concludes with a. valuable index with about 2400 entries.

The book is printed on large size fine- quality paper; the print is small, some- times very smell, in order to accommodate maximum information in minimum space, hut still clear enough for easy reeding.

Although the hook covers a large variety of subjects, it is homogeneous. The author's purpose is to show the connee- tions between various branches of chemical industry. The book is recommended as

a successful effort in achieving this pur- pose. I t is the fruit of about 40 years of teaching and industrial experience, and is written not just for students to study for passing examinations, but more es- pecially to arouse their enthusiasm for this vital branch of chemistry. Chemical industry, as Prof. Henglein points out in the introduction, needs chemists and engineers who can think by themselves.
