precipitates during thermolysis is described ; here the author
has relied mainly upon the results of his own school. In contrast to the first edition, the reproduction of thermolysis
curves for individual compounds has been omitted, because
the detailed appearance of the curves depends too much upon
the experimental conditions. The author restricts his description t o the principal parts of the curves, the horizontal sections and the stability regions, and to the suitability of individual compounds for purposes of gravimetric analysis.
Duval’s book is thus a comprehensive reference work o n
thermogravimetry.
Despite the widespread application of thermogravimetry, it
appears to the reviewer that the relationships of this method
to the thermodynamics of heterogeneous equilibria have not
yet been sufficiently pointed out, even though a profitable
field is offered here. The processes that occur during thermogravimetry are in fact often highly complex and depend upon
the experimental conditions, since the ideal conditions of isobaric decomposition under equilibrium conditions are normally far from being attained. For this reason, the form of
the thermolysis curves depends upon the particle size and pretreatment of the sample, upon the rate of flow and composition ofthe gaseous phase, and upon the rate of heating. Therefore, the decomposition points found in this way need not be
identical with the temperatures at which the equilibrium pressure of a gaseous decomposition product, such as water vapor,
reaches the value of 1 atmosphere.
These comments are not intended t o depreciate the value of
Dirvnf’s book, but rather to serve as an incentive for its readers
to occupy themselves with the still unused potentialities of
t hermogravimetry.
The lay-out and appearance of the book are excellent, in
keeping with the high standards of the Elsevier publishing
house. This volume should not be missing in any chemical
library or inorganic chemistry laboratory.

Analytical Chemistry of Uranium gzU238.03. Published by the

Ryubclrikov and M. M . Senyurin. Translated from the

Because of the widespread use of uranium in nuclear technology, there are numerous methods for determining and detecting uranium in ores, uranium compounds, and alloys scattered in the literature, but so far no comprehensive monograph
on the analytical chemistry of uranium has appeared (with
the exception, perhaps, of a few difficultly accessible compilations 11-41). The present volume is a critical review of
material from over a thousand publications. Following a
general introduction to the chemistry of uranium (Chapter 1),
in which the most important properties of the element, its
isotopes, and some of the most common uranium minerals are
described, a short review is given in Chapter 2 o n the special

inorganic chemistry of uranium, with particular stress upon
analytical aspects. Valuable tables of solubilities and complexing constants i n various solvents are given.
In Chapter 3, o n the qualitative detection of uranium, it is
mainly color and fluorescence tests that are dealt with.
Besides the well known fluorescence reaction in the NaF bead,
reactions with inorganic and organiccolorreagents are descrihed in detail and compiled in a long table. Although the
interferences caused by other elements are described, n o
reference is made to the behavior of neptunium and plutonium. There is also no mention here of the classical precipitation reaction as sodium uranylacetate crystals, which also
works with Np02*@, Pu022@, and Am022q. This is found
somewhat out of place on p. 236.
Chapter 4 contains 174 pages devoted to methods for estimating uranium and thus makes up over a third of the book.
It is subdivided into three sections: A) chemical methods of
analysis, B) physico-chemical methods of analysis, and C)
physical methods of analysis. The subsection on colorimetric
and spectrophotometric methods of analysis without and with
the use of organic color reagents is worth mentioning. Here,
too, the reader finds welcome extensive tabulations with data
on extinction coefficients (pp. 89 and 114).
Methods for separating uranium from other ekements are
given in Chapter 5 , and methods for determining uranium in
minerals and industrial wastes in Chapter 6. Although, for
example, the analysis of uranium/zirconium alloys is described briefly (p. 301), no attention i s called to the danger
of explosions on dissolution of such alloys in nitric acid. The
book closes with Chapter 7 on the testing of the purity and
estimation ofimpurities in uranium, and with a comprehensive
bibliography (1093 references). Here the translator has made
some errors in his retranscription of names from Kyrillic into
Latin script, for it should be CLitte and not Gotro in reference
554, and Ladenbnuer and not Ladenbnyer in reference 98 1. Tke
numerous practical procedures given would have profited
from tests of their experimental usefulness. The print is clean
and tidy, but the lay-out could have been better arranged.
Despite these minor shortcomings, the book is recommended
to all higher institutions of chemical learning, to uranium processing industries, and to analytical laboratories, for it covers
practically the whole of the more important literature on the
analytical chemistry of uranium i n a single volume and helps
one to find rapid recourse to original publications via its bibliography.

The Nobel Prize in Physiology or Medicine was awarded
twenty times between 1942 and 1962, including thirteen
awards for work in biochemical research. For this reason,
the present volumes can be recommended to the chemist.
Many, especially biochemists, will find material in the contents which touches directly their own work. However, this
does not represent the prime purpose of the book; its aims
go much further. All the Nobel lectures held between 1942
and 1962 in the fields of physiology or medicine are reproduced here in English in chronological order, together
with the laudations and biographies of the prize-winners.
The result is an extremely vivid and fascinating picture of the
development of medicine, physiology, and physiological
chemistry over these two decades. When one reads at the
end of the Nobel lecture by Sir Alexander Fleming (1945)
“the time may come when penicillin can be bought by anyone
in the shops. . .” and then considers how soon afterwards not
only penicillin but also a great number of its derivatives became available in sufficient amounts, then one appreciates
