mittee, a permanent staff carries out the program 

 of action as defined !bj the bureau. This staff is 

 situated at the headquarters of the union, and is 

 the pivot of all the organizations connected there- 

 with. The council can also establish permanent 

 committees as they may seem necessary. 



An advisory committee, divided into sections 

 corresponding to the different scientific and in- 

 dustrial branches, considers in detail the questions 

 figuring in the program of action. The associated 

 nations are represented in each section by dele- 

 gates, elected for three years. The delegates of 

 each nation constitute a national committee, whose 

 duties include the study of questions interesting to 

 chemistry from scientific, industrial, and economic 

 points of view. 



A meeting of the council, of the permanent com- 

 mittees, of the advisory committee, and of the 

 General Assembly is held each year, under the 

 title of the "International Chemical Conference." 



The report presented by Professor Lindet, for 

 the Federation Nationale des Associations de 

 Chimie de France, asking that the International 

 Congress be joined to the union, provides that the 

 International Conference shall every four years be 

 converted into an International Congress of Pure 

 and Applied Chemistry. Elections to the council, 

 to permanent committees, and to the advisory com- 

 mittee shall take place at this time. 



The languages for the congress are English, 

 French and Italian. Communications may be made 

 in another language, provided authors give a 

 translation or an abstract in the ofiicial languages. 

 To avoid errors in interpretation, communications, 

 votes, resolutions, and official acts, if not originally 

 offered in French, must be translated into that 

 tongue. 



To encourage research, the council may, within 

 the limit of funds granted each year by the as- 

 sembly, award prizes and medals to the authors of 

 work considered worthy of such distinction. 



MISSOURI EXPERIMENT STATION OF THE 

 BUREAU OF MINES 



Secretary op the Interior Payne, acting on 

 the recommendations of Dr. F. G. Cottrell, di- 

 rector of the Bureau of Mines, has selected 

 Eolla, Mo., as the place for the latest mining 

 experiment station of the bureau. This sta- 

 tion vs^ill look after the mining interests of the 

 Mississippi Valley and will give consideration 

 to the various problems which are met with in 

 the production of lead and zinc. 



After a careful investigation. The Missouri 

 School of Mines and Metallurgy at Rolla, Mo., 

 was selected as an ideal place to carry on much 

 of the actual laboratory and investigative work 

 of the new station. However, it was also de- 

 cided that the central offices of the station 

 should be at or near St. Louis, Missouri. Con- 

 sequently, the plan is that the actual labora- 

 tory and investigative work shall be done in 

 cooperation with the Missouri School of Mines 

 and Metallurgy at Eolla, but that headquar- 

 ters of the station should be in St. Louis. 



For a long time the Bureau of Mines has de- 

 sired to take up, in cooperation with the min- 

 ing and metallurgical industry, those problems 

 met with in the Mississippi Valley where lead 

 and zinc deposits occur. As is well known, the 

 ores of this district are for the most part sul- 

 phide ores and are ordinarily not difficult to 

 treat. However, there are also large deposits 

 of oxidized lead ores in certain districts of 

 Missouri, and their mining and metallurgical 

 treatment presents a serious problem. Con- 

 centration by gravity methods had been tried 

 for years on these ores, and there are many 

 thousands of tons of high grade tailings, as 

 well as crude ore, awaiting prox)er methods of 

 recovering metallic values. Such being the 

 ease, the bureau will carry on such research 

 and investigational work in connection with 

 the treatment of these ores as will assist in the 

 development of processes which will prevent 

 their being wasted, due to the lack of a metal- 

 lurgical process which it may be commercially 

 feasible to apply to them.

Professor E. Eoux, director of the Pasteur 

 Institute at Paris, has been awarded by the 

 United States government the Distinguished 

 Service Medal for especially meritorious and 

 distinguished service which was of great con-

 Forces.
