REPORT 600 A ON THE COVER. Nonlinear spectroscopy Nonlinear techniques such as multiphoton spectroscopy, CARS, DFWM, SHG, and DFG offer advantages in resolution and selectivity over conventional methods. John C. Wright and co-workers at the University of Wisconsin explore the principles underlying nonlinear spectroscopy and describe representative analytical applications.
REPORT 609 A Characterizing ancient bacteria Amber-entombed pieces of ancient life provide a window on the past and may provide novel chemical structures that could have therapeutic value. Raul Cano of California Polytechnical State University describes how organisms removed from amber are classified by their morphological and biochemical characteristics.

625 A Product Review
Basic and applied environmental analytical chemistry. It needs to be more widely appreciated that the activities of basic researchers and the effectiveness of their interfaces to the users of analytical applications are key ingredients of environmental analytical chemistry.
Measuring the masses. The universal response of the quartz crystal microbalance is a double-edged sword that expands and limits the applications. We review recent innovations and differences in instrument design.
