illustrated by the fact that he reviews even the latest papers,
including some dated 1964. However, the selection of
literature reviewed sometimes appears to be a little onesided, and some relevant matters have been omitted or are
only mentioned incidentally, e.g. the bonding effect of
hydrophobic interactions or the importance of the structure
of water to the mechanism of fast reactions.

The Application of Mathematical Statistics to Chemical
Analysis. By V . V . Nalimov. Translated from the Russian
by P. Basu. Pergamon Press, Oxford-London-EdinburghNew York-Paris-Frankfurt 1963. 1st edit., IX + 294 pp.,
54 figs., numerous tables, linen 44.4.0 (about $ 11.60).
This book is composed as a manual for analytical chemists or
physicists. It has obviously been written with a strong background of personal experience and with careful consideration
of the pertinent literature. The reader is assumed to possess
a fundamental knowledge of higher mathematics and mathematical statistics.
The book is divided into nine chapters. The first three deal
with general principles, mathematical statistics in chemical
analysis, and random variables. This is followed by chapters
on the normal (Gauss) distribution and the distribution functions derived from this and o n Poisson and binomial distributions. Chapter 6 deals with the comparative evalution of
chemical analyses, and Chapter 7 with variance analysis. The
eighth chapter presents a statisical treatment of linear relationships, including a short section on correlation analysis.
The closing chapter gives rules and proposals for the planning
of statistical experiments. A particularly valuable list of
further literature is given: 172 references with short descriptions of the contents of books and papers covering the period
up to 1959. This is followed by a most useful appendix with
15 clear tables of the most important statistical functions.
The book contains a wealth of interesting and original
thoughts and of step-by-step calculations of numerical
examples. The experienced worker in this field will find
many suggestions here. The reviewer considers the volume
less suitable as an introduction for the beginner, for the main
themes cannot be followed well enough. The book adopts a
very wide scope, and important conclusions are given
unobtrusively in the text; if these had been made more
prominent by using italic or bold-faced type, their importance
would be more immediately apparent. The symbols used are
clear, but the number of concepts introduced could have been
reduced. Some definitions are imprecise, and the curves of the
Gauss distribution in Figure 1I are poorly reproduced. Some
aspects are omitted or given only brief treatment, e.g. the
question of the distribution of possible true values around a
result found by experiment and the definition of the limit of
On the other hand, the book is full of useful ideas and hints.
For instance, it is pointed out that decisions reached as a result
of statistical criteria are of the nature of agreements. Admirable features of the book are the applications of Poisson distribution to semiquantitative analysis and of binomial distribution to qualitative analysis. Even the Chebysheff inequality
is used in analyses when nothing is known of a distribution
function. Nalimov himself states in his foreword that he
considers his book to be a contribution to the further development of a general statistical theory of chemical analysis. It is
certainly a most stimulating and useful contribution.

Mucopolysaccharides. Chemical Structure, Distribution, and
Isolation. By J . S. Brimacombe and J. M. Webber. B. B. A.
Library, Vol. 6. Elsevier Publishing Co., AmsterdarnLondon-New York 1964. 1st edit., I X + 181 pp., 10figs.
13 tables, linen D M 31.- (about $8.00).
Although numerous monographs have appeared withm
recent years on this topic, the present volume is appealing
because it brings a careful and comprehensive survey of the
more recent literature in clear terms and a systematic order.
The authors have attained this their aim firstly by restricting
the material covered to the mucopolysaccharides the structures
of which have been completely or largely elucidated and
secondly by stressing the classical methods of structural
analysis in carbohydrate chemistry. There are six chapters
given on the individual types of mucopolysaccharides, even
blood-group substances being regarded as such (!). Although
data are presented on their distribution, preparation, biosynthesis, and enzymatic degradation, the book is not suitable as
a work of reference nor for use as a laboratory manual. For
example, data on molecular weights and specific optical
rotations, which the reader wouid have preferred in tabular
form, are scattered throughout the text, and other physical
properties that are of importance especially for the biological
function, such as viscosities, electrophoretic mobilities,
sedimentation constants, etc., are omitted altogether. In
addition, the authors have restricted their discussion in the
chapters on quantitative estimation, separation, and purification to a mere reiteration of the methods available without
commenting on their usefulness. Despite these shortcomings,
the experienced worker in this field will take recourse to this
very informative book, especially on account of its reliable
bibliography, which encompasses 946 titles.

Treatise on Analytical Chemistry. Edited by I. M. Kolthoff,
P. J . Elving, and E. B. Sandell. Part I : Theory and Practice.
Val. 3 and Vol. 4. Interscience Publishers, a Division of
John Wiley & Sons, New York-London-Sydney 1961 and
1963. 1st edit., Vol. 3, Section C (concluded) Separation:
Principles and Techniques: XVII + 439 pp., numerous figs.
and tables, linen 65.15.0 (about $16.00); - Vol. 4, Section
D-l : Magnetic Field Methods of Analysis; Section D-2:
Electrical Methods of Analysis: XXV + 953 pp., numerous
figs. and tables, linen 49.9.0 (about S26.50).
Fifty-three of the total of 124 sections planned for the first
part - Theory and Practice of Analytical Chemistry - of the
analytical handbook “Treatise on Analytical Chemistry” have
now appeared. The present partial volume I 3 concludes
the Section C begun in the partial volume I 2 o n separatory
methods and their principles and practical techniques; the
partial volume I 4 contains section D-1 on magnetic analytical methods and section D-2 on electrical methods of analysis. As for the first two partial volumes, the editors have
secured competent specialists to write the individual portions.
The fundamentals of the methods are described very carefuily
and comprehensively, but often the practical aspects receive
too little attention. For this reason, the reader will miss a
comparitive appraisal of various methods for solving different
specific analytical tasks.
In the partial volume I 3, H. Irving and R . J. P. Williams deal
with liquid-liquid extraction, and J . A . Hermann and J. F.
Suttle with methods of separation based on solid-liquid equilibria. Separation and purification by crystallization and
precipitation are given much more space than the important
new technique of zone melting (only 3 pp.).
The major portion of volume I 3 is devoted to chromatography. The fundamentals of chromatographic methods are
discussed by I. Rosenthal, A . R. Weiss, and V . R . Usdin;
thereafter individual methods are described: liquid-solid
adsorption chromatography by B . J. Mair, liquid-solid ionexchange chromatography by W . Rieman and A . C. Bveyer,
paper chromatography by H. J. Pardera and W. H. McMitllen,
and gas chromatography by C. E. Bennett, S . Dal Nogare,
and L. W. Safranski. Here too, the 240-odd pages afford far
too little space to go beyond the fundamentals and general
execution l o stress the importance of these methods. Thinlayer chromatography is unfortunately not treated in this
partial volume, which appeared in 1961. Electrochromatography could at least have been mentioned in the discussion of the fundamentals of chromatographic processes,
