I t is the intention of this commission to sponsor the publication of critically selected values of constant's and numerical data of importance to the v,-ork of analytical chemists, and to provide analytical chemists with authoritative data and consistent conventions for reporting results. The Commission on Terminology and Expression of ilnalytical Results has begun the study of the format of analytical methods, symbols and units for expressing analytical results, the definition of terms relating to sampling, precision, and accuracy, quality control, design of experiment's, etc. A glossary of terms with equivalents in various languages is also under consideration. Cooperative efforts will also be undertaken in connection with the development of test' methods for evaluating chemical reagents, for the proper use of symbols and other terminology, and on spectrographic data. An important function of the section is the coordination of international meetings and congresses on subjects of interest to analytical chemists. Without such coordination, there is danger that congresses may overlap in interest, become too frequent, or may not obtain general support.. Effective coordination can greatly reduce travel for those interested in attending, and can assist in procuring necessary financial support. The next meeting of the section, its Section Committee, and the commissions will take place in Oxford, England, a t t'he time of the Congress on Analytical Chemistry. No program has yet been formulated for the publication of commission findings. Suggestions for other fields of activity may be submitted to the Analytical Section by writing to S. E. Q. Ashley, 100 Woodlawn Ave., Pittsfield, Mass., U.S.A.
