to working with chemicals. So far as I know, he never studied chemistry, but since he applied chemicals in his work, I suppose he could have been identi fied as a chemist. After all, he proba bly knew as much chemistry as many of our recent chemistry graduates. His cubic style must have been based on a knowledge of crystallographic sys tems, and his use of colors implies a knowledge of spectroscopy. I wonder how much better he would have been if he'd have had a modern chemistry course with its quantum chemistry, ki netics, and thermodynamics! Presented at the Division of Analytical Chemis try. 167th Meeting. ACS, Los Angeles, Calif., April 2. 1974.
You can watch the noise disappear from around weak signals in this dramatic signal-averaging demonstration in your own lab.

Philip W. West is Boyd Professor of Chemistry and Director of the Insti tute for Environmental Sciences at Louisiana State University in Baton Rouge, La. Professor West was awarded the 1974 American Chemical Society Award in Analytical Chemis try (sponsored by Fisher Scientific Co.) and specifically cited for his con tributions to analytical chemistry in the areas of education, forensic chem istry, environmental pollution, highfrequency oscillometry, spectropho tometry, microanalysis, and spot tests. Much of his background is mentioned in his Award Address. In addition to his teaching and research activities, Professor West is editor of Analytica Chimica Acta and is a member of the editorial staffs of Comprehensive An alytical Chemistry and Mikrochimica Acta. He has served on the Advisory Board of ANALYTICAL CHEMISTRY and was author of the biennial review on inorganic analysis for many years.
Signal-averaging equipment doesn't have to cost $10,000 to $15,000 anymore. If y o u ' r e d o i n g analyses requiring the extraction of relatively weak signals from a sea of noise, you'll be interested in our new modular signal averager. Priced at only US$2915* the Ortec 4 6 2 0 / 2 3 offers you a lot more than low cost. On any scope you have available, it displays a constantly calibrated true arithmetic average, so you d o n ' t have to count the sweeps and calculate the average, or use an a p p r o x i m a t i o n . Now about the demonstration. We'll be glad to bring a 4 6 2 0 / 2 3 system to your lab, complete with a s i g n a l / n o i s e generator, and let you watch the noise melt away before your eyes. Or you can hook it in to your experiment in NMR, molecular beam time-of-flight analysis, p h o s p h o r e s c e n c e decay, pulsed

ultrasonics, or many other applications in w h i c h you've previously had to resort to large signal-averaging computers.
