fertilizers and soils, about an equal amount of space given over to crops, and the final 2 3 pages to the production of meat. The mechanical arrangement of the book is very pleasing. Of some three hundred references, seventeen, approximately four times the number in the first edition, are American, and in a general bibliography of about fifty works, six are also from this source. Most of the section on mixed fertilizers is devoted to farmyard manure, a classification which would not conform to standards here. Some of the newer synthetic carriers and mixtures of nitrogen are not given. The unique manner of presenting this broad subject, though general, is so scientifically fundamental and so competently handled that the book should afford an excellent foundation in any general course in agriculture, which could be most easily supplemented by a careful student using the references given a t the end of each section. It should also meet the demand of those interested in the more popular treatment of scientific subjects. However, the general treatment sacrifices much of value to the technologist and hence his interests are not served so well as they might have been. R. E. DEENER Comptes Rendus of the Sixth International Conference of Chemistry, Bucharest, June 22 to 25, 1925. 8’/r X 101/2 inches. 438 pages. Jean Gerard, Secretary, 49 Rue des Mathurins, Paris. The present report of the Bucharest meeting differs from those previously issued in also containing two of the public lectures printed in detail. The first of these is by Ernest Fourneau, upon “The Relation between Chemical Constitution of Compounds and Their Therapeutic Action.” It is in reality a monograph upon the subject and covers 140 pages. The other is by Francesco Giordani, upon “The hTitrogen Problem,” and is accompanied by discussions by E. Burban, Andri. Claude, Camille Matignon, Kai lyarming, Paul Staehelin, and A . Zaharia. The final 200 pages contain extensive reports by standing committees upon physico-chemical standards, analytical reagents for research, coal analysis, ceramic products, food preservation, scientific property, and industrial hygiene. The last report describes hygiene measures in effect in Denmark, Spain, France, Poland, and Ho!land. Practically all of the committee reports, and even the two lectures, were distributed in printed or multigraphed form a t the time of the Bucharest meeting. Consequently this complete Comptes Rendus serves principally to bring the work to the attention of a larger circle of chemists. The delay of more than a
year in its appearance cau;e: no incD:-ve:ience to those actually engaged in the work of the I7nion. ATHERTOS SEIDELI, Chemical Synonyms and Trade Names: A Dictionary and Commercial Handbook.

Editor of Industrial and Engineering Ckemistvy: Table VI of our paper under this title [THISJOURNAL, 17, 643 (1925)] is in error. The rule upon which the calculations used in the table were based is stated by Walker, Lewis, and McAdams, in “Principles of Chemical Engineering,” page 428. This rule does hold for pure substances, and from their statement might be inferred to hold for solutions. Evidently it is not applicable to solutions of the type under discussion. A . R.

New Green for Lime Determination Editor of Industrial and Engineering Chemistry: In THISJOURNAL, 18, 389 (1926) was published a method for lime, which required the use of alizarin cyanine green. Great difficulty has been experienced in getting this dye. I find two other greens that can be used-ceramic green No. 728-D and dianol green. Ceramic green is insoluble and dianol green is removed from
the solution by the zinc hydroxide that is formed. This makes it necessary to take the end point while the solution is being agitated. ., THEGREATWESTERNSUGAR COMPANY
