improvements. In the voluminous appendix, the relevant
legislation, ordinances, and guiding principles are given and
various forms are also reproduced. The book can also be recommended t o employers and to those whose profession it is

The Chemistry of Technetium and Rhenium. By R . D . Pea-
cock. Topics in Inorganic and General Chemistry, Monograph 6. Edited by P. L. Robinson. Elsevier Publishing
Company, Amsterdam-London-New York 1965. 1st. Edit.
ix, 137 pp., 14 Figures, 29 Tables. 55s; 27.50 Dfl.
The main purpose of the monograph, which is a Ievlew of the
present knowledge of rhenium and technetium, IS to be found
in the comparison of the chemistry of these homologous
elements. The author not only describes the various classes
of compounds but explains the material in the light of
modern transition-metal chemistry. Understandably, the
greater. art of the bookis devoted to the chemistry of rhenium. The literature is covered up to the middle of 1965;
however, various omissions have been made, even in the better
documented chemistry of technetium. For example, one
searches in vain for information concerning the technically
and scientifically remarkable inhibition of corrosion exhibited
by pertechnate ions. Nevertheless, the book assists the reader
in gaining a deeper understanding of the chemistry of these
transition elements and will prove stimulating reading for
chemists interested in inorganic and radiochemistry.

Introduction to Nuclear Chemistry. By D. J. Carswell, Elsevier Publishing Co., Amsterdam-London-New York 1967,
1st Edit., ix, 279 pp., 69 figures, 23 tables, Dfl. 32.50.
This book is based on lectures which the author gave over
the course of many years at the University of New South
Wales in Australia. It deals with the structure of the atom
and of the nucleus, the laws of radioactive decay, nuclear
reactions, types of decay, the use of physical nuclear methods
in chemistry, such as the Mossbauer effect and nuclear
magnetic resonance, detectors and their mode of action,
radiation chemistry, mass spectrometry. isotope separation,
neutron sources, accelerators, the actide elements, and the
application of radioisotopes in industry and research. The
concluding chapter lists 16 simple experiments which, without
substantial outlay of time nr money, provide an experimental
insight into radiochemistry and nuclear chemistry.
The book is very simply written. Mathematical and abstract
treatment is largely avoided, sometimes with adverse effects.
For example, the reviewer thinks it unlikely that the description of isotope dilution analysis can really be understood.
In a demanding chapter, in which several electronic circuits
are described and in which the mode of action of a diode or
triode is compared with that of a transistor by means of a
circuit diagram, the statement of Ohm’s law is too trivial. In
the chapter “Actinides” the description of the stability of the
individual actinide valences appears to need revision, as well
as a better presentation.
Despite these drawbacks, the book should be particularly
suitable for students who wish to acquire some overall
knowledge of nuclear chemistry and who have no opportunity
to attend lectures on nuclear and radiochemistry. A big help
in understanding the subject matter is the short summary
given a t the end of each chapter. On the other hand, the
price of about € 3.0.0 seems a little high for this introducC, Keller

Nobel Lectures Chemistry 1901-1921 and 1922-1941.
Issued by the Nobel Foundation, Elsevier Publishing
Company. Amsterdam-London-New York, 1966. Volume
1901-1921, xii, 409 pp., several iiiustrations, Dfl 80.-;
Volume 1922-1941 : 53 pp. several illustrations, Dfl. 80.-.
The first Nobel prizes were awarded in 1901. They were, and
in a certain sense still are, a present from the nineteenth
century to the twentieth, for Alfred Nobel died in 1896. It
must have been particularly difficult at the time to find
among the many eminent chemists the one who deserved to
be the first awarded this great distinction. Cannizzaro, Gibbs,
Thomsen and Berfhelot, Arrhenius, Ostwald and A . von Bnyer,
Emil Fischer, and Moissan were considered, and some of
them received the prizes in later years.The majority of the
votes (11 of 20) went to van’t Haff in 1901. It is a pleasure
to read his Nobel lecture today, more than 65 years later.
van’t Huffdeals with osmotic pressure and chemical equilibria
and it is of interest to note that neither here nor in the motivation for awarding theprizesis there an indication of the discovery of the asymmetric carbon atom. This work is mentioned
only in the eulogy - in one sentence. One becomes acutely
aware of the fact that the material that we learn today in the
first few semesters as something self-evident was by no means
self-evident at the beginning of the century.
In 1902 Emif Fischev received the prize for his fundamental
work on sugars and purines, and in 1903 it was Arrhenius’
turn for his theory of electrolytic dissociation (who can
envisage the time when talk of the theory of electrolytic
dissociation was the order of the day?). In 1904 Ramsay was
honored for his discovery of the inert gases, in 1906 Moissan
for his discovery of fluorine, in 1907 Buclrrrer for his demonstration of cell-free fermentation. Self-evident truths today,
but were they 60 years ago?
Anyone with a sense of history will find his money well spent
o n the two volumes of Nobel lectures that have now been
issued by Elsevier. The reader will encounter many important
men who have shaped our modern thinking, but will meet
them in a way different from that in textbooks. One could
say he will meet them on a more personal level.

BiologicaI Chemistry. By H. R . Mahler and E. H. Cordes.
Harper and Row (Publishers) New York-London 1966.
1st Edit., xv, 872 pp., numerous figures and tables, 63 s.
The outstanding contribution made by American workers
to biochemistry during recent years is very largely the result
of this subject gaining a firm place a long time ago in both
medical and natural science faculties of American universities.
In chemistry, as in medicine and biology, biochemistry has
become a pillar of a modern syllabus admittedly with
different aims. While biochemistry (Dhysiological chemistry)
in the field of medicine is characterized by the functions and
pathology of organs, in chemistry i t is thefundamental set
of chemical and physicochemical principles of the life.determining processes. Although all aspects of biochemistry are
interdependent, they can be developed better independently of
one another if the curriculum is adapted to achieve this aim
in the optimum manner. It is clear that a rapid advance in
one section will promote a similar speeding up in another.
This subdivided responsibility somewhat resembles a technique applied for difficult ascents during mountain climbing.
Two ropes are needed for climbing overhanging rocks. One
is used to pull while it runs through the hook fixed above the
climbers, and the second is carried loosely. After the fixing
of the next hook, the second rope in turn takes up the pull.
The above general remarks seemed necessary in order to
characterize the place and importance of this new work. The
book has been written for chemists by chemists. The authors
have done splendidly, and in many respects have achieved a
breakthrough for biochemistry in the part it occupies in
chemical teaching. The book reproduces fairly accurately
