istry” began t o appear {four volumes, the last of which is
still to be published).
Have therefore, in view of these developments, works such
as those by Gmelin and Kopp become superfluous? For the
reader interested in a given event in the development of
chemistry, Partington may be more suitable, since it presents
the current state of knowledge. However, for those with a
deeper interest in the problems of the history of chemistry,
it will still be necessary to return to the earlier publications,
since Gmeiin and Kopp present the knowledge of their time
in a lucid form. The publishers therefore have good reason to
include these two works in their reprint program.

Grundlagen der Polarographie (Principles of Polarography)
by J . Heyrovsk? and J . K h a . Translated by H . Baiantova.
Edited in German by K. Sch wnbe. Akadeniie-Verlag, Berlin 1965. 1st Edit., xvii, 592 pp., 256 figures. D M 73.The book presents a comprehensive survey of the theoretical
principles of and the general information that can be obtained
by classical direct-current polarography, with reference to
its applications in electrochemical kinetics and the physical
chemistry of solutes. Polarography in these fields has undergone a remarkable and decisive development in the past
two decades.
The authors are successful in their aim of explaining the
basic theoretical aspects without losing themselves in details
of the mathematical derivations, which easily can be found
in the original literature cited. The style is fluid and clear, so
that the theoretical problems of polarography, which often
are not entirely free from complications, are made accessible
even to the novice. The experienced worker will also find this
a n indispensable and frequently consulted reference work.
This applies, not only to specialists in polaropraphy, but to
electrocheniists in general and all ihose concerned with the
application of electrochemical techniques. The present
volume, which reflects more than 49 years’ experience of the
originator of polarography and his co-worker k&a, can
therefore be recommended to a wide &cle\,of readers. It is
to be hoped that this book will lead to a more intensive use
of the versatile possibilities of the polarographic method.
The present work clearly refutes the view that polarography
is unsuitable for fundamental problems. Provided that there
is freedom of choice concerning the electrode material, as is
usually the case in fundamental problems, the opposite is in
fact true, and polarographic methods become the method
of choice.
The Czech edition has been added to and brought up to date
in the German translation, which takes into account the
literature up to the beginning of the 1960’s. The subject
matter is divided into 22 chapters, which deal with the
following topics: physics of the dropping-mercury and mercury-jet electrodes, influence of the resistance of the electrolyte, theory of the diffusion current and kinetically controlled
limiting currents, the theory of reversible and irreversible
steps including their behavior in the case of complexes and
semiquinones, the evolution of hydrogen and its catalysis, adsorption and inhibition, maxima, the uses of the hitherto much
neglected Kalousek switching circuit and the theory of the re-
sulting currents, and oscillographic polarography, with special
emphasis on the Heyrovskd version. The appendix contains
a useful table of half-wave potentials of inorganic and many
organic depolarizers in a series of supporting electrolytes. The
reviewer would have welcomed a more thorough treatment of
the double-layer effect. The results for the dissociation and
recombination kinetics of weak acids also require a much
more critical discussion than the footnote to Table 17/3.
Finally, it should be pointed out that the numerous novel
polarographic techniques, which open up formerly closed
fields to electrochemical kinetics and offer a wealth of new
information, are almost completely absent. Alternatingcurrent, square-wave, and pulse polarography are mentioned
only briefly, and while the increased instrumental demands
are stressed no list is given of the far-reaching possibilities thus
gained. No mention is made of second-order techniques (such
as Faraday rectification, the use of higher harmonics, and
intermodulation methods). The treatment of oscillographic
pulse methods is also too short.
The German edition unfortunately contains more printing
errors than such an important book should. The presentation

An Introduction to Electron Paramagnetic Resonance. By M .
Bersohn and J . C. Baird. From the series “Frontiers in
Chemistry”. W. A. Benjamin, Inc., New York-Amsterdam
1966. 1st Edit., xi, 274 pp., 110 figures, $15.00.
After a general introduction, the authors devote about 120
pages (Chapters 3 to 10) to hyperfine structure, relaxation,
g factors, quantitative measurements, organic radicals,
triplets, inorganic compounds, and double-resonance; a
further 40 pages (Chapters 11 and 12) deal with applications
in chemistry and biology. The appendix gives a more quantitative presentation of the interactions in the two-spin system, and the book ends with a list of the coupling constants
of 130 selected organic radicals and radical ions.
The book is intended for chemists and biologists having no
prior knowledge of the subject. The picture presented is very
general, since e.g. the following topics are covered in a total
of about 30 pages: inorganic radicals, metal complexes,
nonconductors, metals, Mossbauer effect-(lllz pages !), Overhauser effect, ENDOR, optical pumping, and level crossing.
A conspicuous feature of the whole book and particularly of
the tables (g factors, pp. 70/71, and coupling constants, pp.
238-2702, is the c m pl@e disregard of all but Englishlanguage literature. The physical chemist will sometimes be
disappointed by the lack of accuraw Thus in the discussion of
the intensities of the HFS components (p.80), the incorrect,
but convenient, and henqe commonly used counting rule is
described in detail for the H; ion, but the reader is not told
that two protons combine to give a singlet and a triplet,
though this is explained in a n elementary and laborious
manner for the case of electrons (p. 108).
On the whole, the reviewer has gained the impression that
the authors were pressed for time. However, despite the
shortcomings mentioned above, the book will undoubtedly
find a wide circle of readers and contribute to the growth of
interest in this modern field. K. H . H~~~~~~ [NB 570 IEI
