PAGE 931 will be found the Progress Report of the Com ONmittee on Naming Analytical Methods of the Division of Analytical and Micro Chemistry. We think it important t h a t analysts give some consideration to this matter, especially in the writing of papers and reports; it should also interest editors who find t h a t lack of standard and accepted definitions can lead to confusion and inaccurate expression. Acceptance of nomenclature is conditioned by what is published, and, in many cases, authors give little thought to precise meaning. This subject is receiving careful attention from committees of the A.S.T.M. and Optical Society working in other fields. T h e Bureau of Standards has cooperatively set up for the use of its group in publications terminology and symbols for use in ultra violet, visible, and infrared absorptometry (Letter Circular LC 857, M a y 19, 1947). T h e Progress Report is largely the work of Dr. Mellon, who has taken t h e lead and who is conscious of t h e need for active work in this neglected field. T h e passage of the report by the division was delayed by the untimely death of Father Power, and it is now presented so that it may serve as the basis for recommended practice. After analytical chemists have studied it, we hope that they will write us concerning desirable changes and expansion. Since this report was written, Dr. Mellon has been appointed to the A.C.S. Committee on Nomenclature, headed by E. J. Crane, and the writer is now chairman of the division committee. Ronald P . Craham, McMaster University, Hamilton, Ontario, takes Dr. Mellon's place on the committee. It will be recalled that microscopists have published recommended

T H E R E are a number of analytical symposia scheduled, which those in the regions involved should plan to attend. Louisiana State University, Baton Rouge, plans a week's symposium on modern analysis, stressing instrumental methods, beginning February 2, 1948. Arrangements are being made to bring wellknown speakers in various subjects to lecture and lead discussions. The A.C.S. Pittsburgh Section's Analytical Division plans its third analytical symposium for February 12 and 13. In addition to inviting speakers on timely subjects, they request individual papers for the general session. J. R. Anderson, Mellon Insti tute, is handling the arrangements. The Metropolitan Microchemical Society of New York City has tentatively scheduled February 27 and 28 for its symposium on microchemistry, to be held in the American Museum of Natural History. These sym posia all point to heightened interest in all phases of analysis. A report, of the symposium on x-ray and electron diffraction held in Pittsburgh November 7 and 8 is given in Dr. Mtiller's column on instrumentation in this issue. A TRADE pamphlet p u t out by the Nopco Chemical Co., Harrison, N . J., entitled "Interpretation of Analysis for the Lay man," deals with surface-active agents. Typical analyses with necessary relevant information as to the source of the sample are given on one page, and all explanations leading to an interpreta tion of the analysis appear on an opposite page. The presentation is designed, of course, to bring the products to the attention of customers, together with technical information obtained from analysis. This brings to our mind the experience of many analysts that chemists who submit samples for analysis do not know what type of determination t o request and many times may not know how to interpret t h e results. I t would seem t h a t a more techni cal analytical handbook along t h a t line for the staff of larger laboratories could well pay for itself in a more intelligent approach to analysis. We all know of instances where a long, involved analysis was undertaken, and later it turned out t h a t a simpler or different approach would have given more information.
