concepts. The principles of thedispersion process, dispersibility, and stability or flocculation of dispersion form the subject of the next chapter (G. D. Parfitt). Obviously, in the
given context consideration must be given to agglomerates
and aggregates. After all, these structural formations of powdered substances are the reason why dispersion is necessary.
These processes are mentioned in the fourth chapter ( A . G .
Walron), which gives a general survey of the formation and
growth of nuclei in precipitation reactions. The few facts o n
the problem of agglomeration in precipitation for which
space could be found suggest that further research is needed.
The fifth chapter ( S . H . Bell and V . T.Crow/) is devoted to
industrial applications,of dispersions and the relevant methods of measurement. It is followed by a chapter ( W . Black)
on the effects of surface-active agents. The industrial aspects
of dispersion classified according to dispersion machines and
products are summarized in the seventh chapter ( R . Sheppard). The book ends with chapters on inorganic ( H . D. Jefferies) and organic ( H . D. Brearley and F. M . Smith) pigments giving information on pigment-specific dispersion and
other application problems.
The references are given at the end of each chapter, and the
book contains about 500 in all. A short but adequate index
is provided. The presentation of the material is good, the
photographic reproductions being of satisfactory quality and
the schematic drawings clear and distinct. The book deserves
every success.

Introduction to Quantum Chemistry. By J. M. Anderson.
W. A. Benjamin, Inc., .New Yock 1969. 1st. Edit., xiv,
445 pp., numerous Figs. and Tables, bound $ 14.95.
Since quantum mechanics or quantum chemistry became one
of standard courses in chemistry departments about fifteen
years ago, numerous and varied textbooks on this subject
have been published. Although many excellent quantum
mechanics textbooks are available today (Messiah: Quantum
Mechanics; Dike and Wittke: Introduction to Quantum
Mechanics; Saxon: Elementary Quantum Mechanics; Merzbacher: Quantum Mechanics, GotterJied: Quantum Mechanics, etc.), it is still quite difficult to find a suitable text for a
one-semester introductory quantum mechanics or quantum
chemistry course for chemists. The reason for this is that most
excellent quantum mechanics textbooks are primarily
written for physicists and some good quantum chemistry
books (Paufing and Wilson: Quantum Mechanics; Eyring,
Walter, and Kirnbafl: Quantum Chemistry: Kannzman: Quantum Chemistry, etc.), are out of date. In the reviewer’s opinion this book can fill in the gap and can serve very well as a
textbook for a one-semester introductory quantum chemistry course. This book has four striking features: (1) The
Heisenberg and Schrodinger viewpoints are developed and
used simultaneously throughout and the emphasis is o n the
formulation of quantum mechanics. In doing so, students can
get a more general and more rigorous view of quantum
mechanics. (2) The notation used is in line with that found in
the current literature. This enables students t o follow the
papers on quantum chemistry which appear in modern chemical and physical journals. (3) Some problems in the book are
solved by computer. This makes students able to appreciate
the importance of the computer in modern quantum chemistry. (4) Topics chosen in the book are important and useful
to chemists. However, the book also has some shortcomings,
namely: (1) Some presentations are too sloppy or unclear.
(2) There are quite a few typographical errors.
The author begins his presentation with the discussions
o n some intuitions and some experiments in quantum
mechanics; then follows apostulational introduction to quantum mechanics. Both matrix mechanics viewpoint and wave
mechanics viewpoint are introduced and developed simultaneously by a very fresh approach - one which differs from most
competing texts of quantum chemistry. Constant potential
problems such as the free particle, the particle in a box, the

/ Vol. 9 (1970) No. 4
motion of a particle in region of several constant potentials
etc. are discussed. The quantum mechanical concepts of these
problems are emphasized. After briefly describing the manybody, many-coordinate systems, angular momentum is introduced. Following this the harmonic oscillator and the hydrogen atom are treated in quite an elegant manner.
The second part of the book considers the approximation
methods in quantum chemistry. Variational method and
perturbation theory are explained in detail. The applications
of variational method and perturbation theory to atomic and
molecular systems are illustrated very well. The molecular
orbital theory, valence bond theory, Hartree-Fock SCF and
LCAO are discussed. Time-dependent theory and spectroscopic theory are also presented. The author concludes the
book with a descriptive treatment of scattering theory.
Overall, the presentations are good and the approaches are
fresh. However, in some places, I think that there would be a
more effective way to convince readers, but the author just
throws up his hands by asking readers to believe him (e.g.
p. 27 lines 6 and 7). For a textbook of this level (intended for
seniors and first year graduate students), in some places the
presentations should be more detailed. For example, on p. 37,
the derivation of Eq. (1-41) is presented poorly. On p. 347,
without discussing properties of Dirac Delta function or
mentioning it, the author just states: “now Jymei(k’-k) ==
0 ; . . .” (Readers have to believe it!) Despite these minor
shortcomings, I still highly recommend this book to be used
as a textbook for the one-semester introductory quantum

Amino Acids Determination - Methods and Techniques. By
S . Blackburn. Marcel Dekker, Inc., New- YTrk,I;?SlndoD
1968, 1st Edit., xi + 271 pp., numerous figures, bound,
approx. D M 52.-.
This book is intended for the man a t the bench in amino acid
analytical laboratories, research institutes, and in industry.
The title theme is the unifying thread that holds the whole
volume together. The concise and practical nature of the
work is lost sight of only in the opening chapter o n the
history and importance of amino acids analysis, and the
chapter might well have been shortened to make room for
more operating instructions and recommendations. This
would have been to the advantage of the more important
first half of the book, which deals with ion-exchange chromatography and the associated technology and use of modern automatic analyzers, highlighting the author’s knowledge and experience of the subject. The very latest developments in theory and practice have been covered, as far as this
is possible in a widely ramified field characterized by continuous improvements in equipment. The plentiful literature
references in each section are treated only briefly and in
review fashion in the text; occasionally a definite evaluation
would perhaps be preferable.
The second half of the book deals, with acceptable brevity,
with such vital methods and techniques as paper and gas
chromatography, infrared and mass spectrometry, and the
proven high-voltage electrophoresis. All things considered,
the treatment of the analysis of physiological fluids is definitely too short. Despite this, the book is highly recommended
to anyone who uses or runs an amino-acid analyzer.
