Mid-American Symposium on Spectroscopy The 18th Annual Mid-America Sym­ posium on Spectroscopy will take place May 15 to 18 at the Chicago-Sheraton Hotel, Chicago, 111. This meeting is sponsored by the Chicago Section of the Society for Applied Spectroscopy in cooperation with the Chicago Gas Chromatography Discussion Group. In addition to the technical program, given in detail in the following pages below, there will be an instrument ex­ hibit, an employment bureau for regis­ trants, plant tours, and social activities. More information on this meeting is available from Lew Malter, Lew Malter & Assoc, P. O. Box 252, Morton Grove, 111. 60053. PROGRAM SYMPOSIUM ON THE STRUCTURES OF ICE, WATER, AND AQUEOUS SOLUTIONS G.

4 big features in each compact, versatile model! 1. Grating monochromator for high resolution. 2. Efficient optical system for low detection limits and maximum sen­ sitivity. 3. Noise rejection circuit for stable readings. 4. Low hollow cathode (H.C.) peak currents for long H.C. tube life. Many options for your laboratory's spe­ cial needs: recorder, optical density out­ put, constant rate injection pump, H.C. tube warming rack, and various types of burners. Request Bulletin 190.
