with any problem in the antibiotics field, particularly since
publications that are difficult to obtain are also considered.
The literature is covered in part up to 1964, including many
patent references. The printing and presentation of the book
are very good. However, it would have been better to reproduce the formulae from drawings rather than by typesetting. The volume contains a detailed author and subject

whereas even first-year chemistry students are taught that
electrons cannot disappear in redox reactions. Oxidation
numbers and (formal) ionic charges also are mixed u p
indiscriminately, as in the examples:
.4dvances in Inorganic Chemistry and Radiochemistry. Vol. 7.
Edited by H . Emelr‘us and A . Slinrpe. Academic Press,
New York-London 1965. 1st ed., 449 pp.. several illustrations, S15.50.
The present volume[*1 reflects a general unrest in current
inorganic chemical research, which is overlapping to an
increasing extent with the marginal fields of organic chemistry. Thus only two of the six contributions are devoted to
pure inorganic chemistry, the “Halides of Phosphorus,
Arsenic, Antimony, and Bismuth” by L . Kolditz, and the
“Hydride Complexes of the Transition Metals” by M . L. H .
Green and D. J . Jones. The organic component makes an
appearance in “Phthalocyanines” by A . B. P. Lever (despite
the fact that this contribution deals with metal-nitrogen
bonds), becomes more prominent in “Organoaluminum
Compounds” by R . Koster and P . Birrger and in “Carbosilanes” by G. Fritz, J . Grobe, and D. Kummer, and finally
becomes dominant in the “Reactions of Che!ated Organic
Ligands” by Q u . Fernondo.
The presentation and layout of this volume, as af the earlier
ones, is impeccable. Special mention should be made of the
editors’ constant efforts to include contributions by seecialists
from all over the world.
The first five contributions named above are consistent with
th-, high regard in which the “Advances ’ are held. However,
the article on “Reactioas of Chelated Organic Ligands”
leaves one with the impression of having been carried back a
century. The ignorance and indifference shown in this
article regarding the complicated and versatile bonding,
valence, and nomenclature rules for the 103 “inorganic”
elements could scarcely be surpassed.
Thus every bond, whether ionic or covalent, coordinate,
dative back-donation, or hydrogen bond, is indicated by a
valence line. Lone electron pairs are not shown, so that the
reader is left to deduce the origin of the bonding electrons
for himself. This is possible with some loss of time except
where the author, from a desire to surround each carbon
atom with four valence lines and each nitrogen atom with
three, presents completely new structural formulae, as on
p. 206 for bis(diacetyldioximato)nickel(u) (“Ni dimethyl-
glyoxime”). Here the diacetyldioxime has become an ethylene
derivative, and if one lone electron pair is assigned to each
N atom to avoid an electron sextet, the Ni atom must supply
at least four electrons for the bonds to the N atoms.According
to the author, this complex forms a chlorine adduct with
hydrogen chloride :
(C4H702Nz)~Ni 2 HCI
+ (C~HSO~N~)~N~.CI~
Similarly, the reaction of manganese(u1) ion with oxalate ion
is reported (p. 240) to proceed, via a chelate, by regrouping
of bonds, and via free-radical states, according to the overall
equation :

The Ring Index
A List of Ring Systems Used in Organic
Chemistry. Supplement I11 (1962-1963) to the 2nd
edition. Rings 11 525-14265. American Chemical Society.
Washington 1965. 1st ed., vi, 546 pp., numerous illustrations, S10.00.
The third supplement to the second edition of the Ring Index
has now been publishedr*l. It contains all the new ring
systems described in the literature and referred to in Chemical
Abstracts between January 1, 1962 and December 31, 1963.
This amounts to a total of 2741 compounds, whereas the
corresponding figures for 1960!1961 and 1957-1959 were
about 1800 and 2000, respectively. This again reflects the
accelerated growth of knowledge in the natural scienc,eS The
ring index now includes 14 265 cyclic systems
An appendix to the third supplement contains addenda and
corrections to the earlier volumes. The addenda consist
mainly of names and references for new hydro or dehydro
derivatives or for rin systems formerly .known only as
components of c o m p c k d s . The corrections also include
references to better numbering and alternative nomenclature.
The Ring Index needs no special recommendation. I t is so
useful that any volume that carries on the good work must
be regarded as welcome.

numerous illustrations, 51 6.00.
The 46th edition of the “Handbook of Chemistry and Physics” contains 200 more pages of tables and other information
than the 45th edition, so that the book now contains more
than 1700 pages and almost 450 tables.
New features include tables on superconductivity, physical
constants of organometallic compounds, the thermal conductivity of gases, the surface tension of liquid elements, and
trade names of dyestuff intermediates. Other tables have
been revised, e.g. the table on buffer solution , but in the
reviewer’s opinion this section is still too brief. For example,
a survey of the buffer solutions commonly used in biochemistry is missing.
Several mathematical tables have been rearranged, so that
they are now vertical instead of harizontal , and there is no
doubt that a new table (23 pages containing every imaginable
conversion factor will he particularly welcome
Special care should be given in future editions to the clear
definition of the data listed in the tables For example, it is not
very significant to give values for the toxicity of gases and
vapors (in ppm or mg,’l) without explaining what has been
taken as the measure of toxicity. I t is also unfortunate that
