o n furosemide and ethacrynic acid d o not, on the basis of
my own experience, entirely fit the real facts (for instance.
notice the use of “accidentally”). The chapters o n furosemide and ethacrynic acid are laid out in the same way a n d
in clear manner. The references contain nothing later than
1967.
The mode of action and the clinical application of aldosterone antagonists (spironolactone) are explained lucidly
and reference is made to the experimental procedure for the
investigation of these substances. The pseudoantialdosterones which reduce K+ elimination or retention by the
kidneys are described with particular reference t o the two
main representatives of this group, triamterene and amiloride, whose clinical applicability has not yet been fully
demonstrated (bibliography up t o 1968). The diuretic uses
3f the glucocorticoids and the inhibitors of corticosteroid
biosynthesis are described by G. Senff (deceased). Finally,
the book deals with the use of cation exchangers as diuretics.
The reviewer agrees with the editor o n the important
historical contribution of the chapter “Xanthine Derivatives as Diuretics”.
The pleasing appearance of the printing I S somewhat marred
by the fact that art paper has been used only where histological illustrations are reproduced (production costs?).
The editor and his colleagues have succeeded in producing
a coherent and didactically well constructed book which,
in addition to its uses as a handbook, will be of great value
to both the student and the teacher of natural sciences.

Organic Geochemistry. Methods and Results. Ed. by G.
Eglintnn and M . T . J . Murphy. Springer-Verlag, BerlinHeidelberqNew York 1970. 1st Edit., xxiv, 828 pp.,
246 figures, bound D M 178.--.
While biogeochemistry deals with the reIation of sediments
and minerals t o plant and animal life, organic geochemistry
concerns the characterization of organic substances as they
occur in sediments and other natural environments.
The present book attempts for the first time to give comprehensive coverage to one of the youngest and most
heterogeneous fields of knowledge on the fringes of organic
chemistry, biology, and geology: 37 authors write about
their own special fields in 31 chapters.
Chapters 2-6 present the organic chemist’s approach and
discuss the analytical possibilities for isolating and characterizing organic compounds: general methods, gas chromatography, mass spectrometry, isolation of kerogen and
related substances from sediments and fossils.
Chapters 7-12 stress the biological and geological aspects:
evolution, fossilization, sedimentology, organic substances
in sediments, microbiological decomposition, and the biochemistry of the stable carbon isotopes. Chapters 13-19
give an account of the geological frequency of the classes of
organic compounds most commonly occurring in sediments, hydrocarbons, fatty acids and alcohols, fossil carbohydrates, terpenoids, carotenoids, proteins, peptides and
amino acids, and porphyrins.
Chapters 20-30 deal with the occurrence of certain compounds in specific geological situations: conchiolin in
fossils and mussel shells, organic substances in gas occlusions in minerals, chemistry of the humic acids and
related pigments, soil lipids, earth waxes, peat, Montan wax,
fossil and recent kauri resins; kerogen from the Green River
formation, crude oil, petroleum formation, carbon, importance of pre-paleozoic sediments in organic geochemistry.
Chapter 31 deals with the organic derivatives of clay minerals, zeolites, and related minerals.
In spite of the diverse nature of the material and the large
number of authors this book provides a first survey of our
knowledge of a field which in future will play a n increasingly important role not only in science but also in practice.

Electron spin resonance (ESR) spectroscopy has in recent
years gained increasing importance as a physicochemical
method of studying the paramagnetic properties of radicals.
A monograph dealing with the use of this technique from
the standpoint of the organic chemist is now available. ESR
spectroscopy can be used t o obtain information o n the spin
density distribution and thestructure, as well as thedynamic
behavior of radical molecules, e.g. in various solvents.
However, the method has been used successfully for the
detection of short-lived radical intermediates generated
chemically or by electro-, photo-, or radiation-chemical
processes.
The subdivision of the present book into two main sections
is based on the realization that an introduction to the principles of ESR spectroscopy that is to be readily understandable whilst a t the same time taking into account all the
important recent developments in the technique should be
separated from the detailed treatment of themost interesting
classes of organic radicals. In adopting this subdivision i t
is of course necessary to reconcile oneself to repetition, since
the theoretical treatment in the first part is elucidated by
reference to numerous experimental results, which then
appear again in the systematic section. In this way it may
be possible to guide someone with limited experience,
who turns to the book for the solution of practical problems, to the principles underlying the observed effects.
The chapters o n dynamic effects and o n electron-nucleus
interactions are especially pleasing. As, indeed, in the rest
of the book, extraordinary care has been taken here in
citing the original literature. On the other hand, at many
points opportunities have been missed for helping the reader
who wishes to delve further into the subject, and who would
have welcomed advice on more advanced textbooks and
monographs.
The systematic section contains a chapter o n organic
radicals in solution, the relevant data appearing in valuable
tables. Aids are given t o the identification and interpretation of ESR spectra, as well as instructions for the preparation of standard radicals.
The book is well and clearly written and the general presentation is attractive. It will prove to be a n essential tool not
just t o organic chemists bu#q%o to many others.

Physikalische Chemie. Teil I: Einfiihrung in die Gastheorie,

Part I: Introduction to the Theory of Gases, Quantum
Theory, Thermodynamics). By G. M . Barrow. Friedr.
Vieweg u. Sohn, Braunschweig 1969. 1st Edit. 257 pp, 67
figures, 35 tables, paperback D M 19.80.
Gordon M. Barrow’s textbook “Physical Chemistry” which
is widely used in English-speaking countries, is t o be published in German in three volumes. The first part, which was
translated by G. W. Herzog, is now available. It contains an
introduction t o the theory of gases, the quantum theory, and
thermodynamics.
The first half of the book (Chapters 1 to 4) presents a n insight
and a n introduction into the actual principles of physical
chemistry and its concepts. Some general properties and concepts are first presented with the empirical gas laws. This is
followed by a discussion of the kinetic theory of gases and a n
introduction (confined to the barest essentials) to the constitution of matter and quantum mechanics and to classical and
quantum statistics. The partition function is dealt with in
rather more detail. However, it has been necessary here to
