text and several omissions in tables and graphs, some of
which lead to distortion of meaning, and which will have
to be corrected in later editions.
During the past two decades fluorescence analysis has become a favorite analytical technique, which has proved
particularly useful in biological, biochemical, and clinical
laboratories. This is due to its ability to detect a large number of substances, which either themselves fluoresce or else
can be converted into fluorescing compounds by specific
reactions, in astonishingly small concentrations, and at a
relatively modest cost in equipment.
Apart from these points, the authors have succeeded well
in their purpose of presenting a general survey of the
field of surface active substances.
The present monograph is concerned with the currently
available instruments and techniques. The basic phenomena
of fluorescence, the currently available spectrofluorimeters,
calibration methods, and fluorescence standards are all
dealt with briefly but in sufficient detail for routine applications. The fluorescence properties of metal chelates are
presented in great detail, since these form the foundation of
the whole technique. There are further detailed chapters
devoted to the fluorescence of proteins, vitamins, and
steroids, and, rather outside the scope of the present book,
chapters on chemiluminescence and X-ray fluorescence.
Some criticism concerns the chapter on fluorescence indicators; the authors d o not appear to know that the
changes in a fluorescence spectrum are not necessarily
governed by the pH value.
The emphasis of the book is on applications. Since it contains material reprinted from the manuals of two manufacturers it contains a large number of detailed instructions
for use in a wide range of applications, particularly for clinical chemistry. The detailed nature of the presentation and
the lack of theoretical padding make this book appear
particularly suitable for the instruction of laboratory technicians.

Grenzflachenaktive Substanzen (Surface Active Substances). By H . Bueren and H . Grossmann. Chemische
Taschenbucher Vol. 14, edited by W Foerst and H .
Griinewald. Verlag Chemie GmbH, Weinheim/Bergstr.
1971.x, 196 pp., 64 figures, 27 tables, paperback D M 24.-
The present pocket book is an attempt by the authors
to fill a gap in the technical and scientific literature with a
brief survey of everything that is worth knowing about
surface active substances. The subject is discussed under the
following headings :historical review, scientific importance,
physico-chemical principles, chemical composition of
surface active substances, analysis, biological degradation,
industrial use.
The book will be a valuable aid to the interested student
who wishes to find out more about the field than he can
learn from chemistry and technology lectures and to the
practical worker in adjacent fields who wishes a quick
survey. The large bibliography attached to each chapter
also offers an opportunity to pursue the study further by
reference to the original literature.
A number of adverse comments are also justified. Too
much emphasis is sometimes placed on practical use, at the
expense of chemical and industrial aspects (as in the case
of nonionic surfactants). The treatment of the physicochemical principles of surface activity is rather too general
and simplified. N o mention is made of some important
current developments in the surfactant field, such as new
classes of surfactants and the substitution of detergent
phosphates. There are a number of printing errors in the

Worterbuch der Chemie und der chemischen Verfahrenstechnik (Dictionary of Chemistry and Chemical Engineering), Vol. 1 German/English. By L. de Vries and

The 70000 or so entries in this technical dictionary have
been drawn from the whole field of chemistry and also
from the vocabulary of chemical engineering, metallurgy,
and the petroleum, rubber, and textile industries. The
dictionary also contains terms from the fields of physics,
biology, medicine, mathematics, mineralogy, and crystallography. The authors have taken particular trouble
to include recently coined terms from biochemistry,
physiology, molecular biology, biophysics, atomic physics,
spectroscopy, stereochemistry, reactor engineering, and
electronics. Chemical compounds are recorded both
under their trivial and under their systematic names,
although naturally only the simple compounds are
included. Outmoded names still often found in the technical
literature will be found, but are specially marked. At the
end there is a table of the chemical elements, a table of
German weights and measures, and a temperatureconversion table.
This dictionary has been used by us ever since it appeared
and has rarely failed to supply an answer. There is thus
no doubt that this is an extremely useful work, and not
only to chemists but also to engineers and technical
If we consider the sheer bulk of the material handled, it is
hardly surprising that, despite the great care with which
the book has been compiled there are still a few minor
errors. For example, “Rotkupfererz” is only given under
“Cuprit” ; omissions include Widerstandszahl (drag coefficient), Schuttschicht (fixed bed), Formkern (mandrel),
the synonym for film evaporation (film boiling), and under
Verweilzeit the English term “residence time”. Outmoded
names for compounds are not always marked, e.g. “Zinnjodiir”. Neither descriptions such as “Zirkon” for Zr and
“Vanadium” for V nor the spellings “Siliciumkarbid” and
“Silikat” are in agreement with the principles of nomenclature, and there seems to be some confusion about the
spelling of “oxid” (oxidhaltig, but oxydartig), although
particular mention of this is made in the foreword. Since,
however, the entire vocabulary is stored on magnetic tape,
future modifications should not cause any difficulties.
It should be emphasized that these minor blemishes in no
way detract from the work’s usefulness, and it is hoped
that this dictionary will find the widest possible circulation.

Methoden der enzymatischen Analyse (Methods of Enzymatic Analysis). Edited by H . U . Bergmeyer. Verlag

The second edition of this work has now appeared, and
one need only look back to the reviews of the first edition“’
to see that any further praise would be superfluous. Then,
as now, no comparable work existed, and all that remains
for the reviewer to do is to indicate the places where this
new edition (edited by H . U.Bergmeyer with the collaboration of 230 authors) is an improvement on the original
The new edition of this laboratory handbook is essentially
larger and in two volumes. Despite the fact that it has
almost doubled in size, the presentation is clearer, and the
information provided is more precise and more markedly
oriented toward practical use in clinical and biochemical
laboratories. The care that has been taken in the layout
of the book is one of the fundamental factors contributing
toward its clarity.
The general division of the material into four sections has
been retained ; however, the general introduction is now
followed by biochemical reactions as the second section,
then come the methods for measuring enzyme activity,
and finally the methods for the determination of metabolites. The general introduction has been extended to
nine times its original length and has assumed an entirely
new character. In addition to the description of new
analytical methods, such as the enzyme isotope dilution
technique, and information on the automation of analyses,
the clinician will find valuable practical help in the newly
added chapter “Evaluation, Checking, and Assessment of
Measurements”.Stability properties of substrates, enzymes,
and tissue cultures are carefully described and illustrated
by numerous literature references.
Biochemists who work with enzymes will note with gratitude that in the section on “BiochemicalReagents” not only
are more than a hundred of the best known enzymes
grouped together with their properties, but also the
procedures for their activity determinations are given.
In this connection it would be desirable if in future this
part could also be arranged according to the rules of
IUPAC nomenclature, as has already been done in the
Cf. Angew. Chem. internat. Edit. 2, 52 (1963)
section on “Measurement of Enzyme Activities”. Here
account is taken of the mechanization and automation
of enzyme analysis in clinical laboratories, a phenomenon
that is observed more and more these days. With the
determination of GOT, GPT, and LDH as examples,
detailed data on Luiomated analfsis are given, &d for
other enzymes largely kechanized analyses are described.
Analyses by electrophoretic separation, radiochemical
analysis, and to a greater extent fluorometric methods
are given for the first time, in addition to the traditional
methods. Thus, for example, 41 pages are devoted to
LDH and its isoenzymes, seven analytical methods and
four methods of automatic analysis are given, and 51
literature references are provided to ensure the availability of further information. The favored subdivision
into necessary reagents, solutions, method of operation,
etc., has been extended to include data on the precision
of the method and also pipetting schemes which will lead to
a dramatic simplification of the actual execution of determinations. The new edition no longer contains the chapter
on histochemical methods, and in our opinion rightly so,
since such methods are described in the appropriate textbooks and handbooks on histochemistry.
In both the section on the determination of enzyme
activity and the final section on methods for metabolites,
each determination is prefaced by a brief introduction
and the sensitivity and precision of the method are given.
Particular emphasis is placed on the pipetting scheme with
data on the concentrations in the test. The methods given
for the production of preparations of enzymes not commercially available are very useful. Finally, the tables giving the metabolite contents of animal tissues deserve
particular mention, since they represent a valuable compilation of previously published values.
All things considered, this book, which has already made a
name for itself, is indispensable to all practising biochemists, and is a practically inexhaustible source of
information for laboratory practice. It is sure to find a
wide distribution and to be highly popular.
