Furthermore, irreversible potentials (over-voltages) in aqueous solutions and in melts are given here in the form of a
literature survey.
The third chapter has 120 pages and deals with equilibria in
electrochemical systems. The section on dissociation constants (G. G . Grau) of water and inorganic and organic compounds extends over 100 pages. The final section is made up
by a long table of acid-alkali indicators ( R . Appel) and a table
of buffer mixtures (G. G. Gruu).
The compilation of the numerical data contained in the present volume required a vast literature survey, as many numerical values are hidden away in papers that were not designed
for the express purpose of determining constants, but to solve
physico-chemical problems of a different nature. It would
therefore not be surprising if, on checking a reference, the
value given in the literature cannot occasionally be found.
However, if the figure in question is contained in the tables,
it will certainly be traceable, thanks to the excellent clarity of
arrangement. The contributions to the volume of several wellknown authors in the field of electrochemistry guarantees the
best possible results.

laboratory and is to be recommended. In other chapters too
(general, methods, results), the reader is aware that the book
has emerged from practical experience.
Previously unpublished results obtained by the authors in the
clinico-chemical field (not to mention the numerous illustrations and figures, some of them in color) contribute to the
emergence of a nicely lirrished work which documents impressively the importance of high voltage electrophoresis. The
inclusion of large tables dealing with the behavior of various
groups of compounds (anxino acids, peptides, porphyrines, alkaloids, pesticides, carbohydrates, vitamins, etc.) deserves
special mention, as they greatly facilitate the handling of the
book.
A bibliography containing 2500 references (up to 1961) and
a carefully arranged index complete the book, which is
printed in high quality and which is expected to be useful and
stimulating not only to workers engaged in this particular field.
In view of the qualities mentioned above, which are not
detrimented by a few small mistakes and inaccuracies, widespread use of the book cannot only be hoped for, but can be
predicted with certainty.

(High Voltage Electrophoresis, its Scope of Application for
Biochemical and Clinico-chemical Separation Problems).
By R . Clotten and A . Clotten, Georg Thieme Verlag, Stuttgart 1962, 1st Edition, XVI, 556 pp., 111 figures, 113 tables,
price DM 98. - (about $ 2 5 . ~ ) .
In view of the fact that a series of books on paper electrophoresis is already available, is it now justifiable to publish an extensive work o n a specialized subject such as that of high voltage electrophoresis? The reviewer believes that this question
should be answered in the affirmative, since this method,
which is now more than ten years old, has found worldwide
use in the last few years, owing mainly to the successes it has
achieved in the separation of peptides and in combination
with paper-chromatography in “finger-printing”. A monograph dealing with high voltage electrophoresis and summarizing its achievements to date is to be welcomed, especially as this method frequently makes possible a more efficient
separation than any other and since it requires specialized
equipment. The authors, working at the University Hospital
in Freihurg (Germany), studied the application of high voltage
electrophoresis to clinico-chemical problems for many years
and achieved significant results in the analysis of low molecular-weight substances from tissue extracts and body fluids.
Hence, they included in this book the practical experience
accumulated from daily use of the method; as a n example, the
extensive table dealing with inherent and avoidable errors of
the method might be cited.
The authors’ intention of writing a book to enable separation
experiments to be carried out and their results to be interpreted without consultation of the original literature is very
commendable, especially as the method is widely used in
clinical laboratories. However, as a result, nearly half of the
book consists of the reproduction of material which, although
critically selected here, is already known from handbooks of
paper chromatography (coloration techniques, quantitative
determinations). Indications are given to the reader that this
or that coloration method was particularly successful in the

This third volume of communications from the Research
Laboratories of Agfa A<;. at Leverkusen and Munich is dedicated to Dr. Fritz ,4lher.s, who was for many years Head of
the Agfa Photographic Paper Manufactory. As in previous
volumes [l], the latest work on the subject of scientific photography carried out by Agfa is collected in the present one.
The series of articles opens with a description of the work of
E . Klein and R. Mutejec on “UnsolvedProblems in theTheory
of Elementary Photographic Processes”. A very valuable
estimation of the position in this field and a n unusual abundance of literature references are presented. The same authors,
with H. Frieser, then report on some investigations of these
fundamental processes, including: “The Theory of the Density Curve and the Calculation of Sensitivity Distribution”
and physical investigations concerning silver halide crystals.
The following articles by J. Eggers o n problems of photographic developing are concerned, among other subjects,
especially with the mechanism of color development and with
the p H changes in photographic layers during development.
Besides the work on the most diverse aspects of photography
such as sensitometry, masking, reciprocity failure, spectral
sensitisers. rtc., investigations on magnetophone tapes are
also described. The book contains in all 24 contributions from
23 authors.
The most extensive dissertation in the volume, viz. “Color
Couplers” by W.Pelz, deserves special mention. This provides
a comprehensive summary of the present position in this important special subject.
The lay-out of the work is excellent, so that in appearance and
content, this volume will be a worthy successor to those
published earlier.
