A curve for computing lead concentration from step heighth was prepared. The Pittsburgh Plate Glass Co., Columbia Chemical Division at Barberton, Ohio has requested that the foundation outline a program for continuous toiticological control of net chemicals. They mould like a rapid scanning techni-ue for appraising toxicity of product developments. The technique should be as simple as passible, thereby reducing cost. Cost is a predominant factor when the potential aarust value of a nev: chemical is uny.no .sn.. The program would also include full scale toxicity studies, ".-here necessary, when a market has been established for new products. The production of .'.iCH, a chemical whose toxicity was appraised by tr. Paul Gross, continues to cause much skin disease. In cooperation with the bine Safety Appliances Company we will develop several new skin creams which nay aid in the control of the dermatitis. n: October 27, 1945 T: October 29, 1945 fl: / NOV 2 !9d5 :r n|-<^ __________ Francis A.
