Gmelins Handbuch der anorganischen Chemie (Gmelin's
Handbook of Inorganic Chemistry). 8th Edition, new and
completely revised. Published by the Gmelin-Jnstitut fiir
anorganischc Chemie und Grenzgebiete in der Max-PlanckGesellschaft zur Fiirderung d e r Wissenschaften. Begun by

T h e following discussion continues the review [I,2] of the
recently published Gmelin volumes. The six volumes for the
year 1960 are covered.
System No. 29: Strontium. Supplement Volume, 1960, X X X ,
306 pages with 39 illustrations, German-English tab!e of contents, English lieadings and subheadings o n the margins of
the text, paperbound, D M 195.- ( $ 49.--), cloth b o ~ i n d

System No. 30: Barium. Supplement Volume, 1960, X1.V.
569 pages with 76 illustiationa, German-English table of
contents, English leadings a n d sub!icadings on the margins
of the text, paperbound, D M 354. ($ SS.S0), cloth bound
D M 359.-- (S 90. ). Edited by the above-mentioned collabora:ors, and in addition by H . Ge~~l.scl7old,
G. Kir.scli.steirr,
and K. Re4f~Id.
Because of the close chemical relationship between strontium
and barium, these two supplementary volumes, which continue the respective main volumes that appeared in 1931 (Sr)
and 1932 (Baj, will be treated together. Although they only
contain the literature for npproximatcly two decades (Sr :
1931bl949; Ba: 1932 -1949), they are, just as is the case for
other System Numbers, of considerably larger scope than the
corresponding main volumes (Sr: 306 pages with 39 illustrations, in contrast t o 239 pages with 26 illustrations; Ba: 569
pages with 76 i l l ~ i s t r a ~ i o against
390 pages with 31 illustrations).
Twenty-seven percent of the entire text is devoted t o the
occurrence of the two elements (Sr: 8 2 pages; Ba: 155 pages).
Here, as in many other System Numbers, one has the feeling
that in an attempt t o attain completeness, there is somewhat
too much of a good thing. For example, in the chapter on
occurrence i n the biosphere, data are found on the barium content of the ashes of Litliotlin~t~tiiu~~r,
F'ritc14.s w~iculosrrs,and
Eqclui.wtrrni lir?io.srrtiz,of 62 seed samples of Grcirriinnretre,of the
ash of orange juice, of the air-dried kernels and the shells of
Brazil nuts, o f t h e woody part o f t h e sheath membrane ofBertlrulletici ewcP/str, of thc mcmbrLincsof the ostrich eye (divided
into cornea, sclerotic coat, lens, chorioid, retina), of 14 newborn rats, of calf urine, of 56 urinary calculi, of 27 1 gallstones,
efc., etc. A poll of the purchasers o f the Gmelin Handbook
would probably show that the number of readers who a r e
interested in such special details is negligible and insufficient
t o compensate for the expenditure of time required in recording these details.
O n the other hand, the chapter o n the technology of strontium
a n d barium and their compounds is considerably shorter
(Sr: 5 pages; Ba: 34 pages). Details a r e given here o n the
processing of the raw materials celestite and strontianite, and
barite a n d witherite, respectively, as well as o n the industrial
production of the two alkaline-earth metals a n d their most
important compounds (oxides, hydroxides, peroxides, nitrates, chlorides, chlorates, sulfates, carbonates).
Following o n f r o m this is the chapter on elementary strontium and h:uium (Sr: 59 pages, Ba: 83 pages), in which the
preparation on a laboratory scale (including the isolation of
isotopes), as well as the physical, electrochemical, chemical,
physiological, and analytical properties of the two elements
are discussed in t h e usual way. T h e summarizing sections o n
common reactions of strontium and barium ions given here
