Beyond the Flyleaf Organic SyntEaeses. Collective Volume H. Edttal 3>y A. H. Blatt, ix -f- 654 pages- Jobui Wiley & Sons, Inc., N. Y. City, 1943. Price, $6.50. 1 HIS volume contains in revised form not onljy theiraaterial that appeared in the annual voJunotes X - X 1 X of this series, but new- and Lcnproved checked procedures for eleven otlaer syntheses. In addition, the editor has. included under Methods of Preparation, Ln each case, the procedures of preparative^ value found in the literature covered by tOhemical Abstracts through volume 35foir 1941. Such data are particularly helrnful a t present when the demand for space on. the pages of our chemical journals o-d'ten forces authors to record preparative details in such condensed form t-hat it is sometimes difficult for others tfcorepesatthe work. Of many cither helpful features in this volumes attention, should be called to the use of the CFimical Abstracts name as a subtitle wher* that name differs from the

title of the preparation; special designation of compounds that are commercially available at a cost lower than that for which they could probably be prepared in most laboratories; and a multiple index. This includes a general index and other divisions listing type of reaction, type of compound, formula and illustration. A few irregularities in nomenclature were noted. In naming organometallic compounds it may b e a question which of the radicals should stand first, and whether the name of the compound should be represented by one word or two. Examples of all usages indicated were found in the names of these substances. Names of carbinols, also, were sometimes represented by one word, and in other places by two. This does not interfere appreciably with the value of the book. This work is printed on good paper, in pleasing type, and the method of presentation, editorial supervision, press work, and binding are in keeping with the high standard of excellence set by previous volumes of the series.

The Total and Free Energies of Formation of the Oxides of Thirty-Two Metals. Maurice de Kay Thompson, 89 pages. The Electrochemical Society, Inc., 3000 Broadway, N. Y. City, 1942. Price $1.00. X m s pamphlet presents recalculated and averaged Gibbs free energies and heats of formation for most of the common metallic oxides, as derived from published articles on chemical equilibria, the electromotive force of reversible cells, or the third law of thermodynamics. It should prove especially valuable to the technologist occasionally utilizing such figures, but lacking adequate library facilities or without the time or inclination to undertake his own correlation of the original data. As a critical review, reasonably to be
Why the Vane in the MULTICIOSE Improves Dusyiffcting Efficiency
The V G Typ MULTICLONE
I N REMOVING dust, fly ash and other susi pended particles from gases, mechanical separators whirl the gas into a cyclone which centrifugally throws out the suspensions. Efficiency of this action depends upon the uniformity with which the whirling gas is distributed in the tube. The more uniform the distribution, the greater the effect of centrifugal forces upon fine as well as coarse particles, resulting in more complete recovery of ALL suspensions. ^ In contrast to conventional cyclones where gas entry is concentrated through a single side port, the MULTICLONE distributes the gas into 8 uniformly-spaced cyclones. This finer break-up promotes smoother flow, better separation . . . and results in substantially higher recovery and improved efficiency!
This is just one of the many basic advantages built into t h e MULTICLONE. To get t h e fu 11 s t o r y , send f o r .
