has developed, in various parts of Germany as well as in
other European countries and America. In the final
section of the “Historical” chapter a number of tin compounds that have been known and used for many centuries
are described.
The second part contains a chapter on the geochemistry of
tin and also a chapter on minerals and workable deposits.
The chapter on cosmochemistry gives information on the
frequency of occurrence of tin in the universe and its
occurrence in the solar spectrum, in star spectra, and in
meteorites. The up-to-date nature of the material is
particularly clear from a short section on the tin content
of moon rocks (for the entire volume, the literature has
been scanned up to 1970). The chapters on geochemistry
and minerals occupy a large amount of space (160 pages),
and describe the behavior of tin in rock and deposit
formation, and also the paragenesis and the chemical and
physical properties of the tin minerals. Information on the
deposits, as far as they are used, is to be found in the final
chapter. This also gives the major producers, the production
figures for individual countries over the last few decades,
tin reserves, and a survey of the price variations of the
metal, both in general and in detail.
System No. 61. Silber, Teil B I (Silver, Part BI).
Compounds with the inert gases, hydrogen, oxygen,
nitrogen, fluorine, and chlorine. Chief editor: Rudolf
Keim, 1971, vi, xxiv, 542 pp., 154 figures, bound.
DM 648.--.
It is only a short while since part A of System No. 61,
dealing with the history and occurrence of silver and also
with the element as such, was published“], and now we
have here the first section of Part B, which deals with the
compounds of silver. As in some of the other recent
volumes of this series, in many places the strictly systematic
approach is allowed to break down in order to give a
chemically clearer picture. Alkali metal and alkaline
earth metal double compounds with the same silvercontaining anions are handled at the same time as the
corresponding silver compound. For example, the description of Ag(r1) fluoride is followed by a description
of all the fluoroargentates(11). In general, this will be
welcomed by the chemist. However, anyone for whom the
topic in question is completely unfamiliar will find literature
searching more difficult, and this is even more true for
the non-chemist. It is therefore hoped that the alphabetical subject index announced for the final volume of
“Silver-B will help to reduce this difficulty.
The present volume begins with a description of the
sorption of the inert gases and hydrogen by silver, and
also of their solubility and diffusion in silver. Although no
well-defined compounds between silver and the inert
gases are, as yet, known, silver does react with hydrogen
to form a compound with the composition AgH, which
exists at any rate in the gaseous state. Solid silver hydrides
have certainly been described, but their existence is
uncertain. In the silver-oxygen system, Ag,O occupies the
most space. In addition, oxides are known in which silver
occurs in the oxidation states of + 2 and +3. In the
silver-nitrogen system, the description of silver nitrate
occupies 37 pages. A further 66 pages are taken up with
solutions of AgNO, and systems containing silver nitrate
and alkali metal and alkaline earth metal nitrates. More
interesting and stimulating for the chemist, however, are

the sections on “Berthollet’s silver fulminate”, the main
component of which is Ag,N, and on silver azide, silver
amide, silver imide, and the silver salts of the lower nitrogen
oxy-acids. Most of the papers on the silver-fluorine system
are of recent date, if one ignores those on the binary silver
fluorides Ag,F, AgF, and AgF,. In particular, the fluorine
compounds of Ag” and Ag”’ have become known due to
the work of R. Hoppe, mainly over the past two decades.
In the silver-chlorine system, AgCl is the only binary
silver-chlorine compound whose existence has been definitely proved at present. The AgF, analog AgCl, may
exist in the gas phase. AgCl is one of the most thoroughly
investigated of all chemical compounds, among other
things because of its photochemical properties. The
formation and the crystallographic, mechanical, magnetic,
electrical, optical, and chemical properties of the pure
compound occupy 147 pages, and the description of
AgC1-containing systems takes anbther 30 pages. The
rest of the volume is concerned with the silver salts of
chlorine oxy-acids.
The literature is covered up to the end of 1969, and in
some cases (e.g. KAgF,, RbAgF,, and CsAgF,) as far as
1970.
Although recent Gmelin volumes have contained more
tables than previously, the present reviewer feels that still
more information should be presented in tabular form,
thus making the rest of the text easier to read. This would
be of particular assistance to users who cannot read
German.

Survey of Organic Syntheses. By C. A . Buehler and D.E.
Pearson. John Wiley & Sons Ltd., Chichester 1970. 1st
Edit., ix, 1166 pp., bound E 13.00.
The book presents a survey of the principal methods for the
preparation of organic compounds. The discussion of each
reaction is headed by a general reaction scheme which is
followed by a description of the possible uses and the limitations of the method in question. Corresponding to the
entirely practical orientation of the book, reaction mechanisms are considered in only a few instances. Finally, the
uses of the method are iliustrated by well-chosen examples
with the relevant literature references. The arrangement of
the book is based consistently on the type of compound
being prepared. The 20-chapter book begins with the
methods for the synthesis of alkanes and ends with those
for nitro compounds.
I must confess that the incongruity of the book‘s claim that
it presents a substantially complete account of the methods
of practical importance and its relatively small size made
me skeptical at first, particularly since the book is aimed
both at students and at research chemists. However, a close
examination provided a pleasant surprise.
The authors have been very successful in their presentation
of the subject matter with special concentration on what is
essential. All the methods that have proved useful in
laboratory practice are presented briefly but without
omission of any essential points. Important experimental
data are given in every case. The selection of the methods,
the examples, and the references reflect critical judgment
of a high order. The use of the book is greatly facilitated
by a comprehensive author and subject index.

In conclusion, it can be said that the book succeeds in
providing a really useful survey of methods for the preparation of organic compounds. It is of great practical
value, and should soon become a standard work for the
organic laboratory.

This work will “enable students and young industrial
chemists to become thoroughly familiar with the field of
plant protection, while offering advice and help to specialists”. In addition, it helps to fill a gap as a textbook and a
survey of this field. The authors are chemists and biologists
working mainly in industry (23 for Farbenfabriken Bayer
AG, one for Shell Research Ltd., one for Farbwerke Hoechst
AG, and two for the Department of Ecological Chemistry,
Gesellschaft fur Strahlenforschung mbH). The authors
“tried to mold the large mass of data into a coherent whole.
They also aimed to present the material in homogeneous
sections, but primarily in a form dictated by the subject”.
The biological background is given “whenever it is needed
for understanding the subject”.
After the Introduction, devoted to the scientific significance
of pIant protection (17 pp., 22 refs.), volume 1 deals with
the development of new plant protection agents (25 pp., 22
refs.), commercial formulations (14 pp., no refs.), and in the
chapter on Insecticides-with the general aspects of the
biology and testing of insecticides and acaricides (19 pp.,
23 refs.), the combatting of the emergence of resistance
(19 pp., 14 refs.), naturally occurring insecticides (33 pp.,
353 refs.), chlorinated hydrocarbons (98 pp., 553 refs.), carbamates (27 pp., 160 refs.), insecticidal phosphoric esters
(205 pp., 810 refs.), insecticides belonging to other groups
(10 pp., 30 refs.), and contact insecticides (9 pp., 25 refs.). It
also covers chemosterilizing agents (11 pp., 65 refs., alkylating agents, antimetabolites, etc.), insect repellents (9 pp.,
33 refs.), insect sex attractants (25 pp., 73 refs.), acaricides
(44 pp., 248 refs. ; biology, historical, active substances),
ncmaticides (10 pp., 27 refs.), bird and mammal deterrents
(13 pp., 152 refs.),and rodenticides (43 pp., 1000-1200 refs.).
This comprehensive book gives an excellent survey of the
fields mentioned above, and the extensive references permit
these fields to be studied in depth. Stock protecting agents
and the chemical analysis of active substances receive a
somewhat cursory treatment. Questions of nomenclature,
which are so important, are dealt with in the chapter on
phosphoric esters.
The second volume is particularly valuable because it surveys the important fungicides (166 pp., 440 refs.) and herbicides, and comprises an excellent chapter on the residues
of plant protection agents which can be detected in food
and in the environment. The textbook nature of this work

is enhanced by the color pictures of the main fungal plant
diseases in the general part of the chapter on fungicides
(40 pp., 43 refs.), and by color pictures of the main weeds in
the section on herbicides. There is a very interesting section
on phytohormones or natural plant growth substances
(30 pp., 300 refs.). These two volumes can altogether be
warmly recommended, and should not be missing from
the bookshelves of any laboratory dealing with residue
problems.

Experimentelle Einfuhrung in die Anorganische Chemie
(Introduction to Experimental Inorganic Chemistry).
By H . Biltz, W. Klemm, and W Fischer. Walter de Gruyter
u. Co., Berlin 1971, 63.-70. Revised edition, 228 pp.,
28 figs., 1 table, bound, DM 21.--.
The revised edition of Biltz, Klemm, and Fischer differs
from the previous one principally in that the theoretical
chapters have been considerably enlarged. The section on
chemical bonding gives a concise and up-to-date treatment of the atomic structure ofelements. and then describes
the three types of bonding (ionic, covalent, and metallic).
Although this only takes 7 pages, nothing essential has
been omitted, and the topic is presented in a clearly understandable fashion. Appropriately. the most recent definition of the acid-base concept is also given, and the concept
of pK is introduced.
The text is amplified with tables of data on the most important indicators (with end-point range and color of the
indicator acid or base), solubilities, pK, and pK, values
for the more important acids and bases, and oxidation and
reduction potentials. Such data are very important for the
quantitative description of chemical processes.
Despite these improvements, the size of the book has increased only slightly, if at all, due to the deletion of some
data from the analytical section and certain sections, e.g.
“Electronegativit y”.
The book, which is very attractive typographically and in
its general appearance, is a considerable improvement
over the previous edition, and will certainly please those
who are already Biltz, Klemm, and Fischer enthusiasts. It
can be recommended without reservations to all first-year
chemistry students and to any student who is taking inorganic chemistry as a subsidiary subject.

Isonitrile Chemistry. Organic Chemistry, a Series of
Monographs, Vol. 20, By. I . Ugi. Academic Press,
New York, 1971.Ist Edit., xii, 278 pp., numerous illustrations, 8 tables, bound S 14.50.
Despite the fact that review articles have appeared recently
on individual aspects of isonitrile chemistry (B. Zeeh;
L. Malatesta), the present book deserves a warm welcome
for the way in which it summarizes the information on
the structure, syntheses, and reactions of isonitriles
(isocyanides) in a single monograph of 256 pages. Not
only does this book provide an introduction to the chemistry of isonitriles, but it also takes the trouble to present
the position as it exists today.
The material is divided into the following chapters: 1, The
Structure of Isonitriles; 2, Isonitrile Syntheses; 3, Kinetics
