ANHYDROUS AEROSOL HAIR SPRAY SYSTEMS 309 In conclusion, it has been found that pH measurement in anhydrous ethyl alcohol has revealed valuable information regarding propellent stability and corrosive characteristics of hair sprays. The nonaqueous field seems to be a very fruitful one for the investigation ofpH behavior with the glass electrode. (Received May 8, 1962) BIBLIOGRAPHY (1) Sorensen, S. P. L., Biochem.

THE EIGHTH SPECIAL AWARD May 8, 1962 Hotel Biltmore, New York City VIeToP. 1•. W•EATLE¾, P•.D., research associate in the Department of Dermatology, Stanford University Medical School, was honored by the Society with its Special Award for 1962, in recognition of his work with the lipids of the skin surface, especially sebum. Dr. WheatIcy has contributed greatly to our knowledge of the chemical composition of sebum. His work suggests new pathways of cholesterol synthesis and has led directly to the establishment of squalene as the forerunner of cholesterol. One of his most notable scientific achievements was the demonstration of provitamin D in the epidermal cells. This was unsuccessfully looked for in the sebum by all previous investigators.
