" ^ Summer Symposium program was published in t h e M a y issue, R. P . C h a p m a n , t h e general chairman, has been thoughtful enough t o send us a fuller outline of t h e program, which we sincerely hope will interest you enough so t h a t y o u will attend. T h e meeting scheduled for J u n e 20 and 21 a t Michigan State College promises to fulfill t h e high s t a n d a r d s set b y previous conferences. The program appears to be one that will appeal to a good cross section of the profession. S. E. Q. Ashley, well known to analytical chemists throughout the country and recently appointed secretary of the Analytical Section of the International Union of Pure and Applied Chemistry, will open the symposium with some observations on the practice of analytical chemistry based on his many years of experience in the field. His paper will be followed by a short series of papers dealing with certain tools and techniques. O. D. Shreve will take a critical look at infrared, ultraviolet and Raman spectroscopy with respect to the characterization or estimation of materials of unknown or ill-defined constitution and will refer to some recent developments which facilitate the application of absorption spectroscopy to this type of work. C. F. Tufts will discuss methods by which surface geometry and structure can be determined using techniques that unify data from light microscopy, electron microscopy, and electron diffraction and will indicate how this information amplifies that obtained by other tools such as wet methods, spectrographic techniques, and x-ray diffraction. James E. Hudgens will discuss developments in the rapidly expanding sphere of radiochemistry, including use of radioactivation methods for determining trace elements. Paul D. Zemany will describe an application of mass spectrometry to the handling of nonvolatile materials. Richard H. Hughes will give a rapid survey of the current status of micro(Continued on page 17 A)
