Anorganische Chemie [Inorganic Chemistry]. By K . A. Hufmann. Edited by U. Hufrnann and W. Riidurff. Verlag
Friedrich Vieweg & Sohn, Braunschweig 1963. 17th completely revised and extended edit., XI1 + 862 pp., 122 figs.,
10 colored spectra, linen D M 28.- (about S 7.-).
Even the exterior of this new edition of “Hofmann-Rudorff’
differs from its predecessors; the format of the book is
larger, and the typographic appearance has been improved.
The individual chapters are now organized more clearly;
simultaneously, numerous significant transpositions and
revisions have taken place in many sections, with great
benefit to the book as a whole. Numerous illustrations have
been modernized or replaced, without significant increases
in the length of the book. The well proved division into
metals and nonmetals has been retained, and a good supplementary chapter deals with organometallic compounds,
water-like solvents, the solid state, catalysis, molecular
structure, atomic nuclei, and extraterrestial chemistry.
After an introduction comes the discussion of the elements
oxygen and hydrogen and of the properties of water, including osmosis, the ionic theory, the law of mass action and its
applications, followed by sections on the rare gases and the
periodic system, and explanations of ionization, oxidation,
and reduction. Next nitrogen and its compounds and the
Group VI elements and their compounds are discussed. Sections o n atomic structure and the chemical bond follow.
The reviewer suggests that in future editions, atomic structure
and the fundamentals of the chemical bond should be
described immediately after the laws of stoichiometry, for
then numerous phenomena such as oxidation and reduction
and concepts involved in the ionic theory can be explained
and derived in the logical manner.
The treatment of the chemical bond, particularly in complexes, where recourse is made to valence bond methods and
the ligand field theory, is particularly good. The descriptions
of the elements and their compounds are mostly brought up
to date. A few minor errors may be referred to here: nitrous
acid is known in the gaseous - i.e. the free - state; the
so-called stannic acids are not oxide hydrates; the dark red
polyvanadate that occurs transiently o n acidification of
vanadate solutions is not an octavanadate, but probably a
dodecavanadate; the existence of trichromate and tetrachromate ions is very questionable; in the formula Cr 0 5 ,
the ligand occupying the fourth coordination site (ether,
pyridine, ere.) is missing; Mn3Q ions and not M n 0 4 Q are
formed during the oxidation of manganese(I1) sulfate with
peroxodisulfate in the presence of Ag@ ions.
All in all, this is a praiseworthy textbook which will certainly
gain many new friends in addition to its old acquaintances.

Chemisches Praktikum fur Mediziner und Studierende sonstiger
an Chemie interessierter Wissenschaften (Practical Chemistry for Medical Students and Students of Other Sciences
Affiliated to Chemistry). By R . Schwarz and P . W . Schenk.
Verlag Johann Anibrosius Barth, Leipzig 1964. 13th Edit.,
152 pp., 3 figs., stiff covers, DM 4.20 (about S 1.10).
The group of students for whom this book is intended consists mainly of medicine and biology students. Consequently
the principles of chemical education conveyed - experiments
in the chemistry of the individual elements, wet separation of
cations, anion analysis - are tailored t o fit the needs of this
group. However, there is a lack of experiments acquainting
the student with biochemically important methods of analysis
(e. g. adsorption and extraction, including chromatography,
pH measurements and titrations using the glass electrode,
colorimetric and photographic experiments, ion-exchange
techniques. ere.). Instead of a chapter on the standardization
of sodium hydroxide solutions for titrations with oxalic acid,

a short note on commercially available ampoules containing
standardized solutions would have sufficed .- The theoretical discussions are sometimes good (e. g . bases) but often
too short ( e . g . the chemical bond). I t might be more advantageous to omit this chapter on the chemical bond and refer
the student to good textbooks - for it is not intended to spare
the student the study of these - and instead to give a more
profound treatment to topics (e. g. the law of mass action, the
ionic theory, buffers, and pH) that are of prime importance
for medical and biology students. The formula for nitric acid
with two double bonds should be modernized.

Diuretics. Chemistry and Pharmacology. By G. de Stevens.
Vol. I of the Series: Medicinal Chemistry. Edited by G . de
Stevens. Academic Press, New York-London 1963. 1st Edit.
XI11 + 186 pp., numerous illustrs., linen $7.00.
George de Stevens, who is well known o n account of his fundamental work on diuretics, presents with his monograph on
the pharmacology and chemistry of diuretics the first volume
of a new series o n medicinal chemistry.
The book is divided i n t o nine chapters. Following general
physiological and pharmacological considerations, xanthenes
and pyrimidines, triazines, organomercury compounds, sulfonamides, thiazides and hydrothiazides, aldosterones, and
compounds which d o not belong to any of these classes are
dealt with in seven separate chapters. The final chapter is
devoted to therapeutic applications of diuretics for treatment
of hypertonic disturbances.
The first chapter contains two sections, one on the functions
of the kidneys, and the other on the pharmacological use of
diuretics. The latter section ( 2 pp.) is unfortunately far too
short and does not d o justice to the vast importance of this
field. - The xanthenes and pyrimidines receive attention o n
about 15 pp., the triazines on 6, and the organomercury compounds on 10. In view of the diminished practical importance
of these groups, this treatment is absolutely adequate. Sulfonamides, thiazides, and hydrothiazides are dealt with
thoroughly o n about 70 pp., and the aldosterone derivatives
on about 25, with coverage of all aspects. The concluding
chapter o n the therapeutic applications of diuretics for
reducing high blood-pressure is well written and gives valuable
information and incentives for further work on this extremely
important field of indications.
In contrast to the series “Fortschritte der Arzneimittelforschung” founded in 1959 and the series “Progress in
Medicinal Chemistry” started in 1961, de Stevens appearently
wants to treat a single field of chemico-medical research in
each individual volume. The volumes planned for the future
will sometimes deal with research topics that have so far not
been reviewed comprehensively, and hence the series is to be
welcomed. However, monographs on analgetics and psychopharmaceuticals are stated to be in preparation, and it is
therefore questionable whether this duplicity and overlapping
of topics with analogous articles which have, in some cases,
been published only recently is worthwhile and advantageous.
However, if we are to restrict our criticism t o the present first
volume, then the author/editor is to be commended for his
comprehensive and fine presentation of this difficult material,
and the publishers for the purposeful outlay and orderly
