Dr. O. K. Rice, instructor in Chemistry at Harvard, was yesterday presented by the American Chemical Society with the $1000 Langmuir award, which is annually given to the most promising chemist in North America under 30 years of age.

The award is in recognition of outstanding research in pure chemistry, in which Rice has been lecturing for two years. Rice's work involves the application of modern physics and mathematics to chemical problems, and he has published several treatises on that subject. He is a graduate of the University of California '24, and did research work at Leipzig University.
