to evaluate a large number of known structures. One minor
failing is the unclear way in which the formulas are numbered,
which could give rise to errors. The chapter devoted to the indole
alkaloids of Alstonia species is a supplement to the first nine
chapters of vol. XI. The chapters on the alkaloids of the Papaveraceae and of Senecio are very thorough and therefore very
useful; they reflect the endeavor to use alkaloid chemistry for
chemo-taxonomic purposes. The last chapter is devoted to the
legal chemical aspects of alkaloid chemistry. Its social importance alone makes this chapter an essential part of the book.
The penultimate chapter, “Alkaloids Unclassified and of Unknown Structure”, presents something of a problem. As a collection of all those compounds which could not be classified
under any other heading due to lack of chemical information,
it could have had some value. In its present form, however,
it includes compounds whose classification presents no difficulties. In some cases, the same compound even appears in two
places, once in this chapter and once in the appropriate chapter
in the same volume (venoterpin, pp. 208 and 458; cassipourine,
pp. 323 and 464). Part of the trouble is certainly due to the
relatively long delay in publication; to judge from the references
most of the reviews were written in 1967, since only in exceptional cases are articles published in 1968 considered.
In general, it must be said that the volumes under review, like
all the previous volumes, represent an increase in our store of
knowledge, and one which no library specializing in this subject
can afford to be without.

Tables for Use in High-Resolution Mass Spectroscopy. By
R. Bings, J.S. Littler, and R. L. Cleaver. Heyden and Son
Ltd., London 1970. 1st Edit., xx, 160 pp., numerous tables,
DM 97.-.
The tables compiled by Bings, Litter, and Cleaver are intended
to assist in the “peak matching” technique for mass determnation with high-resolution mass spectrometers. The authors
appear to have had AEI instruments chiefly in mind.
The first table gives the most important mass lines in the
spectra of perfluorokerosene, perfluoromethyldecalin, perfluorodimethylcyclohexane, and heptacosafluorotributylamine,
which are frequently used as reference components. The table
also contains factors which enable the ion masses of the mass
lines of a reference substance to be converted into the 13Canalogs. This is extremely helpful for people whose instruments d o
not have a digital mass indicator; users of more modern equipment will hardly ever use these factors.
Much the same situation is found with Table 2, which contains
factors for the determination of further mass lines in the reference compound. Since factors of up to 1.5 are given, while
for example Varian instruments (SM 1) only permit a mass difference of about lo%, this table again can only be used fully
by the possessors of certain types of instruments.
The next table contains the corresponding values for fluothane.
The final table simplifies the mass determination of compounds
with hetero atoms, which are composed of different isotopes.
It shows in graphic form the isotope ratios for chlorine, silicon,
sulfur, boron, and bromine, for increasing numbers of hetero
atoms, and also combinations of chlorine and bromine atoms.
It can also be used to obtain the contribution of these hetero
atoms to the precise ion mass. This table is thus very useful
for the mass determination of compounds containing hetero
atoms, particularly as such values are not given in other collections of tables for the determination of empirical formulas.
The book is completed by an appendix containing the tried and
trusted “Henneberg Tables” for mass determination.
This collection of tables is thus an important aid, but principally
for those laboratories carrying out precise mass determinations

with instruments not fitted with digital mass indicators. Of this
limited clientele, some will undoubtedly be frightened off by
the high price. This appears to be due to the attractive binding
(artificial leather) rather than the contents.

Coordination Compounds. From the series Studies in Modern
Chemistry. By S. F. A. Kettle. Thomas Nelson and Sons Ltd.,
London 1969. 1st Edit., vii, 220pp., f 1.75.
The present series now includes a monograph on coordination
compounds, written by a very notable English author belonging
to the younger generation of theoretical chemists. The contents
are divided into eleven chapters: 1. Introduction; 2.Nomenclature and geometrical structure of coordination compounds; 3.
Preparation of coordination compounds; 4. Stability of coordination compounds; 5. Crystal-field theory of transition metal
complexes; 6. Ligand-field theory of transition metal complexes; 7. Electronic spectra of transition metal complexes; 8.
Magnetic properties of transition metal complexes; 9. Other
methods of studying coordination compounds (vibration spectroscopy, resonance spectroscopy), 10. Thermodynamic aspects; 11. Reaction kinetics of coordination compounds. There
is an appendix containing brief discussions of some applications
of group theory, the Russell-Saunders coupling scheme, the significance of ligand group orbitals, and examples of Tanabe-Sugano diagrams. The text is supplemented by numerous clearly
arranged tables and figures.
This very clearly written monograph attempts to bridge the gap
between the standard textbooks and the almost unmanageably
large number of publications in the field of coordination chemistry. The author is writing mainly for advanced students, and
assumes an elementary knowledge of A 0 and MO theory,
chemical kinetics, and thermodynamics. He is principally concerned with the coordination compounds of the transition metals, but in a number of places he also draws attention to complexes of the main group elements. It is pleasant to find
numerous references to the analogy between the coordination
relationships in solution and in the solid state, but regrettably,
there is no discussion of the large number of coordination compounds in which the central atom is formally in a lower state
of oxidation. Again, a monograph like this, which deliberately
goes beyond the range of the elementary textbooks, ought to
have references to the more important works in the literature
(e.g. to review articles on important sub-topics). Despite these
objections, however, the book can be thoroughly recommended
to any chemist whose mzin gnrerest is “classical metal complexes”.

Free-Radical Chain Reactions. By E. S. Huyser. John Wiley
and Sons Ltd., New York - London 1970. 1st Edit., 387 pp.,
numerous figures, bound, f 9.50.
The study of radical chain reactions has long ranked as a domain
of physical chemistry; in lectures on organic chemistry this type
of reaction is usually only mentioned in passing, with reference
to a few reactions, such as the chlorination of methane. Today
this topic is of importance in both preparative and full-scale
industrial organic chemistry, and in the present work
E. S. Huyser has undertaken to present the basic principles of
the kinetics and mechanisms of these reactions clearly and in
a manner understandable by any chemist. The complicated kinetic equations are derived in so detailed a manner that even
those less experienced in mathematics should be able to follow
them in every detail.
Chapters 1-4 deal with the fundamentals of the mechanisms,
kinetics and the relationships between structure and reactivity.
The following sections are concerned with the principal types
of chain reactions: aliphatic substitutions (greatest emphasis
being placed on halogenation), radical additions (the compound
being added and the unsaturated substrate are separately and
systematically dealt with), eliminations, and radical rearrangements. A separate chapter is devoted to the chemistry of in-
