triene (4 h, 127-128 “C) a mixture of the homo-lH-azepines
( l ) and (2)iwas formed (total yield 35 %)-which was separated by preparative gas chromatography. Presumably the
compounds are formed by valence isomerization of initially formed methoxycarbonylaziridines. The N M R spectra
of ( I ) and (2) are not temperature dependent, i.e. valence
isomerization does not now take place. ( I ) and (2) do
not enter into cycloadditions. Irradiation of ( I ) gives a mixture of (3) and (4)while (2) is virtually unaffected. J. org.

The high detection sensitivity of electrochemical analytical
methods has contributed to the widespread use of polarography. The sensitivity of any analytical method can be substantially increased by integrating processes. Inverse polarography constitutes such a process, in which substances
present in a n electrolyte solution are collected by deposition
on a stationary mercury drop or mercury pool or on other
electrodes made of suitable materials with simultaneous
selection by the applied potential. The process is therefore
particularly suitable for trace analysis.
The present work gives the first really comprehensive and
up-to-date treatment of this process. The first section contains a concise and very lucid review of the principles of the
enrichment process. The second section deals with the electrochemical methods used for the quantitative determination
of the collected substances. A detailed experimental section
follows, in which emphasis is given to the description of the
electrodes and the apparatus employed. This section also
contains a discussion of the sources of error. The second part
of the work deals with the methods used to determine
particuIar elements and includes the relevant literature data.
The highly informative book can be recommended without
reservation to everyone interested in this field.

As far as the average chemist is concerned, technical dictionaries are often unsatisfactory. Despite the fact that he is perfectly capable of understanding “Keton”, “ketone”, or
“cetone” without their help, they nevertheless burden the
luckless reader with pages of translations for terms that are
obvious to anyone expert in the subject. Certain dictionaries in the chemical field omit these terms; such dictionaries
simplify the problem for the chemist who is trying to read a
paper in his own subject[ll. If, however, a paper is to be
translated into the foreign language, there still remains the
problem of the correct usage of words, the problem, in short,
of terminology.
The present book is not a dictionary but a series of parallel
texts, the French and the English versions being printed on
facing pages. In this way, in the guise of a very simple but
comprehensive introduction to chemistry, it actually provides
a comparison of the terminology used. A wide range of

Tetrakis(acetatomercurio)methane, C(HgOCOCH3)4, a crystalline, stable, water soluble substance has been prepared in
good yields by D . S. Mntteson, R . B. Cmtle, and G . L. Larson
by heating a mixture of C[B(OCH3)2]4 and Hg(OCOCH&
under reflux. Pure C(HgOCOCH3)4, m.p. 265-285 “C (dec),
gives a white precipitate with NaOH and with SnC12. An
iodine compound C(Hgl)4, m.p. > 300 “C, can also be formed. The stability of the C-Hg bond may be explained by the
shielding of the carbon atom by the four Hg atoms. / J. Amer.

topics in physical, inorganic, organic and analytical chemistry is covered. It must be admitted that in places the material is rather outdated. (In 1934, when the original GermanEnglish version of the book was published 121, it may well have
been true to say that “Sugden’s parachor method is much
used in Britain!”) As an introduction to chemistry, however,
the book is surprisingly clear and free from errors. The presentation is in general limited to facts and to theories that
have stood the test of time. With a few exceptions, the French
translation faithfully reproduces current usage, and should
provide a quick way for the English-speaking reader to get
to grips with this terminology; in the same way, Frenchspeaking readers will be able to acquaint themselves with
contemporary English usage. I a m convinced that both
groups will learn to value this book, and in many cases will
make use of it as a chemically-orientated dictionary and
language textbook.
In a book like this errors are particularly dangerous though
possibly, in view of the breadth of coverage, unavoidable.
Thus “Cardiac glycosides” are not “les glycosides du coeur”;
“ribose” is “le” and not “la”; DNA has a “structure en
double hClice”, not “a double filet”; adrenalin is “une
hydroxy-amine”, not “une hydroxylamine”; ESR is “RPE”,
never “RPM”; chemical displacements are “diplacements
chimiques”, not “transferts chimiques”. Fortunately mistranslations such as these occur in only a few chapters, and
these are generally more up-to-date than the rest of the book
and thus offer the reader fewer difficulties in other respects.

Nine contributions from eleven eminent authors, including
the editor, have been effectively combined into one homogeneous work. The subject is approached from various
points of view. The book has been written for scientists in
whose work highly dispersed solids play a role. Particular
attention is given to problems of interest to manufacturers
and users of pigments wishing to keep up with the latest developments. One should not be dismayed by the fact that the
dispersion process is influenced by numerous factors that are
difficult or impossible to define in practice. The editor lays
stress on the fact that the sensible use of certain guidelines
can lead to better dispersions and a better understanding of
the dispersion process. This alone is a good enough reason
for “students” of all ages to peruse this book.
The first two chapters (I: M . J. Jaycock; 11: A . L. Smith) deal
with the scientific principles concerned in solid-liquid interfaces. Starting with the forces between atoms, ions, and molecules, the authors go on to discuss boundary surface energy,
wetting, adsorption, and, finally, electric double layers and
zeta potentials, covering innumerable surface properties and
