two protons of the S-methyl group of methionine appear in
the methylation product, unfortunately could not be incl Jded .
A comprehensive review of chemical aspects and functions
of human and animal hemoglobins is contributed by W. A.
Schrodinger and R.T. Jones. A very original feature is the
description of the construction of a paper model of the 9chain of hemoglobin A. The structure and metabolism of
collagen are exhaastively discussed in a brilliant article by
W. Grassmann et al. In the final chapter, L. M. Jackmairn
first presents a short but very informative introduction to
nuclear magnetic resonance methods, and then with the aid
of a number of typical examples, he discusses the application
of NMR to the elucidation of the structures of natural
products. Special attention is given to spin decoupling and
the application of nuclear resonance to questions of stereochemistry.

ABC der Chemie (ABC of Chemistry) (2 volumes). Verlag
Harri Deutsch, Frankfurt 1966. 1st Edit., 1590 pp., numerous illustrations, 40 tables, bound, total price DM 89.80
(about S 23).
Good reference books are always welcome, and the present
2-volume work must be described as good. It contains some
12000 entries and 800 illustrations. For many of the entries
one finds not only definitions, but descriptive articles which
partly have the character of handbook articles. For example,
under the entry “Lijsungsmittel” (solvents) is given a 3’,2page table listing 75 solvents with their densities, melting
points, boiling points, flash points, methods of drying, and
solvent powers. Similarly detailed information is given, c.g.,
under “Nomenclature”, “Coal”, “Nuclear reactors”, etc.
The article on “Laboratory”, which covers over six pages,
unfortunately is rather inane, and the space could have been
put to better use.
It is unlikely that everything in a reference work will be correct, but the number of serious errors helrg is small (e.g. adamantane is not a tetracyclic. but a tricyclic hydrocarbon, and
in the list of Nobel Laureates the merits of Krebs and Lipinann
are interchanged). More often one finds i’nformation that is
not strictly accurate: for exiimple, in the article on enzymes,
it is stated that *‘ ., they enable reactions to proceed that
would occur only under extreme con6nlons in the absence of
the catalys ”
Nevertheless, the work would have merited the grade “very
good” were it not for the fact that the editors have adhered
with Teutonic thoroughness to a spelling that is now considered archaic for technical literature. For example, they use
“Azetyl-Koferment A” instead of “Acetyl-Coferment A”
(“Coenzym” should be used rather than “Coferment” in any
case), and “Azetonzyanhydrin” instead of “Acetoncyanhydrin”; one wonders why they did not have the courage to
“B 543 IE]
extrapolate to “Azetofenon”. H. Grijnewald
Praktikum der makromolekufaren organischen Chemie (Laboratory manual of macromolecular organic chemistry).
Edited by D . Braun, H . Cherdron, and W. Kern. Dr. Alfred
Huthig-Verlag, Heidelberg 1966. 1st Edit., 250 pp., 25
figures, DM 26.-.
In view of the great importante of macromolecular organic
chemistry, universities are showing a growing tendency to
incorporate this important branch of organic chemistry
into their curricula in the form of lectures and special
courses. A handy primer corresponding to “Gattermann”
for practical organic chemistry therefore h d S become a
necessity. The present w,mk is matched t o the situation in
Germany, and was produced with the support of the “Plastics
and Rubber’ Group of the Gesellschuft-Deutscher Chemiker.
Many companies have made tested laboratory procedures
available t o the compilers. The book gives not only a series
276
of excellent and carefully selected exanples of the preparation
of the various types of polymers, but also a general picture
of the precautions to be taken in laboratory preparations
(choice of reaction conditions, purification and storage of
monomers, temperature adjustment, control and termination
of polymerizations, etc.). The theory of the macromolecular
compounds is also clearly presented in the various experiments. The reviewer finds it rather disturbing that the
examples begin with number 300 and that the decimal classification is used elsewhere.
As is only to be expected from these authors, the book is an
excellent introduction to practical macromolecular chemistry
and will certainly be warmly welcomed in all technical

Physikalische Anorganische Chemie (Physical inorganic
chemistry), by M. D . Sienko and R. A . Plane. Translated
and enlarged by F. Steinback S . Hirzel, Stuttgart 1965.
1st Edit., 46 figures, 32 tables, 160 pp., paper D M 18.--.
One must be quite optimistic in order to believe that an
understandable discussion of those fields of physical and
theoretical chemistry with which inorganic chemists are
currently involved can be treated in 169 small-format pages.
The abundance of material presented, the many useful tables,
and the easy reading seems to make this book suitable for the
beginner, who is less concerned with understanding and
noting every detail, but rather with obtaining a general
picture. Precision is not the stiong point of the book, and
one does not always giin the impression that the authors
themselves fully understand what they are writing about,
particularly in the chapters on atomia and molecular theory.
This impression is probably more pronounced in the German
translation than in the original. The German text is in fact
clumsy in many places. Expressions translated too literally
from the English version often do,not correspond to German
usage. For example, the correcf German term for “normalization” should b~ “Normierung”, rather than “Normalisierung”. and “orbital quantum number” is not “Orbitalquantenzahl”, but “Nebendn’antenzaht”. “Legendre polynomials” are not “Kugelfunktionen”, “valence bond” is not
normally rendered by “Valenzbindung”, and hybridization
and degeneracy are entirely different concepts. There is no
“procedure called resonance”. “Der Orbital” sounds odd
when one is accustomed to “das Orbital”. The reader is
recommended to use in addition a more thorough treatment if
he is interested in the theoretical part.

Kleine Quantenmechanik (Quantum mechanics in brief), by
W. Wessel. Physik-Verlag GmbH.. MosbachIBaden 1966.
1st Edit., 161 pp., 46 figures, cloth D M 16.80.
As the author remarks in the introduction, he would like his
book to appeal to that kind of non-physicist who might have
been enthused in the 1920’s by Somrnerfeld’s “Atombau und
Spektrallinien” (Atomic structure and spectral lines).
The particle-wave dualism and the particular role of probability statements in quantum theory are well presented. The
author is wary of philosophical conclusions, despite his
tendency towards belletristic insertions. The central theme
of the hook is guidance, as simply as this is possible,
along the path that led Heisenberg to the development of
matrix mechanics.
The subject matter is made somewhat difficult to follow by
the fact that important and also secondary concepts and
equations are simply pdlltd out of thin air without proof, or
with the reniatk that their proof w d d be too difficult.
Anyone who expects an introduction to the current formalism of quantum mechanics to enable him, for example,
to obtain a better understanding of its chemical applications
will be disappointed. However, for a theoretical chemist it
