Book Review Mathematik fr naturwissenschaftler und Chemiker (Mathematics for Scientists and Chemists). By H. Sirk and M. Draeger. Completely revised by M. Draeger

all the chapters have been completely revised, e.g. the chapter
o n emulsions has increased from 30 to 56 pp. and the chapter
on ointments includes references to silicone bases. hydrocortisone ointments, e f c . Modern techniques in such classical
fields as the preparation of pastes, powders, soaps, suppositories, pills, syrups, capsules, tablets, and dragees are dealt
with. The particularly important practical section o n tabletting faults provides an excellent basic introduction to the
methodology. Treatments more suitable for a textbook are to
be desired in some sections, e.g. that on solutions for injection. The sections o n the preparation of n a t u r a l drugs is
particularly valuable, since their therapeutic use has been
greatly undervalued in face of the abundance of chemical
pharmaceuticals. The same applies to the section o n homeopathic pharmacy. The completely new illustrations might have
been supplemented by technological flow-sheets for the
preparation of pharmaceuticals.
This is a book which will be useful not only to the student of
pharmacy, but also to practising chemists in the pharmaceutical industry.

Fortschritte der Strukturforschung mit Beugungsmethoden
(Advances in Structural Analysis using Diffraction Methods). Edited by R. Brill. Vol. I. Friedrich Vieweg & Sohn,
Braunschweig; Interscience Publishers, a division of John
Wiley & Sons, New York-London 1964. 1st Edit., VIII +
221 pp., 102 figs., linen D M 48.- (about S 12.25).
The appearance of this new series on “advances in structural
analysis using diffraction methods” has closed a gap between
the numerous original publications in journals and extensive
monographs on the subject. I n this first volume of the series,
individual topics selected from this vast field are discussed by
acknowledged experts ( G . E. Boron, B . K. Vainshtein, J .
Karfe, W. Hoppe, H . Jagodzinski, and A. Niggli). In addition
to two articles on the application of neutron and electron diffraction to the determination of structures, particularly the
determination of the positions of hydrogen atoms, there is a
review of methods for measuring phase angles. Two further
sections are devoted to thermal background variations and to
the interpretation of the diffuse interferences occurring in
crystals with dislocations. Finally, a short discourse on some
symmetry problems is given. Every user of this book will be
grateful for the instructive examples and mathematical derivations included. The numerous references given will also
prove a great aid for the perusal of original publications

Chemie und Technologie aliphatischer f luororganischer Verbindungen (The Chemistry andTechnology of Aliphatic Organofluorine Compounds). By D . Osteroth. Collection of
Chemical and Chemical Technological Reviews. New
Series 59. Founded by F. B. Altrerzs, edited by R. Pnmmerer,
L. Birkofer, and F. Goubeau. Ferdinand Enke Verlag, Stuttgart 1964. 1st Edit., VIII, 195 pp., 8 figs., 41 tables, linen
D M 58. - (about $15.00).
The author has attempted to provide a survey of the development of the chemistry and technology of aliphatic fluorine
compounds up to the year 1961. The book deals with syntheses of fluorinated hydrocarbons, alcohols, ethers, aldehydes, ketones, carboxylic acids, and compounds containing
nitrogen and sulfur, as well as with their chemical reactions.
I n view of the rapid development and vastness of fluorine
chemistry, n o single author can reasonably be expected t o give
a complete critical account of the whole field. The reviewer
thus looked in vain among the literature cited for numerous
references to methods of preparative importance.For example,
the synthesis of monofluorocarboxylic acid esters or monofluoroketonas is covered better by the publications of E. D .
Bergmonn. Fluorination by perchloryl fluoride is not mentioned, nor are cycloaliphatic fluorine compounds, such as the
pharmaceutically important fluoro steroids. Interactions of
N-bromoacetamide and hydrogen fluoride with olefins, and
Angew. Chem. intrrimt. Edit. 1 Vol. 4 (1965) No. 2
reactions with difluorocarbene or fluorochlorocarbene have
also been overlooked. Reaction mechanisms are hardly touched upon, but patents and technological aspects are more
fully covered.

Mathematik fur Naturwissenschaftler und Chemiker (Mathematics for Scientists and Chemists). By H. Sirk and M .
Draeger. Completely revised by M. Draeger. Verlag Theodor Steinkopff, Dresden-Leipzig 1963. 9th Edit., xii +

The value of“Sirk” is demonstrated by its many editions,
and now it has appeared in a new edition completely revised
by M. Drrrcger. Despite radical alterations, the character of
the book has been maintained, and o n the whole, the presentation - as well as the typographical appearance - of the
volume are clearer. This has been achieved partly by a reorganization of the material. The elementary mathematics
hitherto appended at the end now appears together with one
section each on combinations and determinants in the new
first part of the book. Infinite series and approximation
procedures are discussed in a new fifth part. The practical
examples in thermodynamics are now gathered together in a
single chapter in the third part (functions with several variables). I n addition, even more effort has been made here than
in previous editions to conveying a lucid and intelligible appreciation of mathematical concepts in order to simplify
understanding of the methods described. In this connection,
the section o n the basic number e, the detailed discussion of
the geometrical interpretation of simple, first-orderdifferential
equation as a vector field and of its general integral as a oneparameter series of curves, theclesr treatment of the method of
the integrating factors, and the section applied to differentiating between the concepts of “necessary” and “sufficient”
conditions can be cited as examples. Furthermore, the illustrative examples given in the text are supplemented by numerous problems whose solutions are given in the appendix. There
is a brief summary at the end of each chapter to assist rapid
orientation.
A few sections had to be shortened to make room for these
welcome additions and innovations. Thus, treatment of the
method for cd!CUhting errors by the law of least squares and
of Taylor series has been omitted, and elimination of the
section on the Schrodinger equation has consequently led to
the lack of mention of boundary conditions, eigenvalues,
and eigenfunctions of a differential equation. In view of the
increasing importance of electronic computers, a somewhat
more extensive treatment of iteration procedures would have
been desirable.
This new edition of “Sirk/Draeger” is an exceptionally lucid
and well-planned introduction to the fundamentals of higher
mathematics and can therefore be earnestly recommended to
every student of chemistry. Here not only will he find the
mathematical basis of classical physical chemistry, but
he can also acquire the background which will facilitate his
explorations into specialized fields of modern physical and

Carl Wilhelm Scheele. Apotheker - Chemiker - Entdecker. By
0 . Zekert. Vol. 27 of the series “Grosse Naturforscher”
edited by H . Degen. Wissenschaftliche Verlagsgeseilschaft
m.b.H., Stuttgart 1963. 1st Edit., 142 pp., 23 illustrations,
linen DM 15.80 (about S4.00).
Carl Wilhelm Scheele (1742-1786) was one of the most prominent chemists during the transition from the phlogistic to
the antiphlogistic eras; his biography and achievements are
recounted in the present volume. Many of the results of his
investigations can be regarded as the beginnings from which
organic chemistrydeveloped into an independent science. Even
though Wdhfer’s synthesis of urea is generally accepted as the
starting point of synthetic organic chemistry nowadays, it
should not be forgotten that, during his investigations of “the
coloring material i n Berlin blue”, Scheele prepared hydrogen
