The redder is amazed at the author’s exquisite command of
the data on the evolution of chemistry. Anyone who has ever
taken the trouble t o trace back the development of an idea or
the repercussions of a n original discovery by recourse t o the
original publications will appreciate the vast effort that has
been expended by a single author herc in order t o producc
this excellent “History of Chemistry”.

Crystallographic Data on Metal and Alloy Structures. Compiled by A . Taylor a n d B. J . Kogle. Dover Publications Inc.,
New York; Constable & Co. Ltd., London 1963. 1st Edit.,
263 pp., paperback $ 2.25.
This book of tables was prepared, according t o statements
by the authors, from original literature, the ASTM data file,
Pearson’s Handbook of Lattice Spacings a n d Structures
of Metals and Alloys, Structure Reports, Strukturberichte,
and “Landolt-Bornstein”. The columns in the tables
contain in series: chemical formula (in alphabetical order),
occasionally the mineral name/crystal system, indications of
the structural type, and, if known, ASTM index data/space
group/lattice constants/number of formula units per unit
cell. T h e contents are arranged in three parts: Table 1
contains about 2300 “Alloys and Intermetallic Compounds”
- where, however, a large number of halides (!), sulfides, and
selenides are included ; Table 2 contains borides (about
9 3 , carbides (about 105), hydrides (about 45), nitrides (about
l I O ) , a n d oxides (about 350) together with a number of
silicates and a few carbonates; Table 3 contains data on
elements.
Judging from the title, more detailed and more comprehensive data o n the crystal structures proper might have been
expected; partly it would be sufficient t o include a n additional column of “references” and t o reduce, for example,
the abundant space allotted t o lattice constants. It is difficult
to understand - in view of the title - why the authors havc
augmented their data by a n apparently random selection of
information o n non-metallic compounds, e . g . halides and
oxides. It is also not clear why the data given for silicates are
so incomplete, why (occasionally erroneous) mineral names
a r e given for oxides but mostly none for sulfides, arsenides,
ere. Moreover, the ASTM index data, i.e. d-values and
relative intensities of the three strongest X-ray reflexes, can
only seldom be used for purposes of identification, when
recourse cannot be had t o the complete X-ray diffraction
diagram.
The booklet may occasionally be of value as a supplement
t o other literature, especially for getting a first information.
Its low price is attractive.

Oxidation Mechanisms. Applications to Organic Chemistry.

Most mechanistic investigations carried o u t during the past
thirty years were concerned with substitution, addition, elimination, and rearrangement reactions, and only these were
dealt with in textbooks. However, the simultaneous appedrance of these two monographs shows that there is also a wide
interest in oxidation (and reduction) reactions and their mechanisms. Both books cover the material t o an extent that
would fill out a course of a one-hour lecture per weak for a
380
semester. Stewrirt arranges his presentation mainly according
t o oxidizing reagents, whereas the arrangement by Writers
is based (albeit none too strictly) on the type of substrate being
oxidized. Neither book attempts to achieve exhaustive co.
verage; in Strwi/rt’streatment some aspects ( ~ . gozonolysis)
ai-e omitted altogether, because they have been reviewed within recent years. Instead, he gives a detailed discussion particularly of chromic acid and permanganate oxidations. Wrrtcrs
emphasis mainly oxidations which involve a one-electron
transfer, for he himself has participated significantly in the
elucidation of t h e course of these reactions. His book is intended principally for students, and hence he gives only a few
references t o original publications and does not include an
author index. Stewnrt, on the other hand, cites about 400 articles, which will help his readers t o find easier access t o more
specialized aspects of the subject. Biochemical oxidations are
discussed in a separate chapter by Stewnrt, but Writers only
touches upon this subject.
The reviewer is reluctant t o recommend either book more than
the other, for both are stimulating and are critically written.
Organic chemistry institutions should acquire both of them,
for they complement each other to a certain degrec.

Azeotropy and Polyazeotropy. By W. Swietoslrrwski. A translation from the Polish edited by K. Ridgwny. Pergamon
Press, Oxford-London-New York-Paris 1963. 1st edit.,
226 pp., numerous illustrs. and tables, linen f3.10.0
(about S9.75).
This monograph is a new edition of the book which appeared
in 1957 in Polish.
In part I (pp. 13-146), individual azeotropic mixtures and
series of azeotropic mixtures are dealt with, with particular
attention to the azeotropic boiling range even for ternary and
quaternary mixtures. An especially tong chapter is devoted t o
interesting azeotropic mixtures with a saddle-like temperature
profile. The concept of polyazeotropy is introduced in the
second part (pp. 147-160) and illustrated with the example
of coal-tar distillation. Part 111 (pp. 161-192) deals with
special polyazeotropic systems, with the dehydration of
ethanol, and with experimental methods for determining
azeotropic distillation ranges. I n part I V (pp. 193-205), a
short discussion is given of the methods for thermochemical
investigation of azeotropic mixtures, particularly the estimation of enthalpies of evaporation and of mixing.
The book contains numerous illustrations and is intended
primarily for the use of the practical experimenter. The
author’s highly condensed description of ebulliometry and its
use in practice for examining azeotropic mixtures is excellent.
Experimental difficulties a r e not passed over without comment.
The monograph makes n o demands o n the theoretical knowledge of the reader, and is thus readily understandable even
for beginners, although the overall clarity suffers somewhat
because of the vast amount of experimental material included.
It should also be mentioned that a clear distinction is not always drawn between rules that have been derived empirically
and regularities that have been derived by calculation from
thermodynamics.
The layout of the book is satisfactory, although the print is
sometimes smudged or broken and although there are several
misprints. The book contains numerous references t o literature souices (312 in all) and can be recommended t o anyone
who wishes t o b e come acquainted with the problems and
applications of azeotropic distillation. Moreover, the book
will go a long way t o alleviate the lack of coordination that is
frequently extant between research and applied work. This
intention of the author has been well achieved in the reviewer’s
opinion, for the book offers interesting incentives t o workers
in both fields.
