Dr. Suskind has now gone on his vacation,and the actual work on this will not be Initiated until his return. Meanwhile it is desirable to clear away any and all unfinished matters relating to the work. I talked over the situation with Dr. Suskind before he left and went over a memorancum which he had prepared after examining all the material which you had supplied. In tills were a few questions which I shall indicate. We now have the information on the formulation and percentage composition of the * 1. Dibasic stearate (Dutch Boy BS-207) 2. Tribaslc maleate (Dutch Bo y - Tri-Mai) y. Orthosilicate and silica gel (Dutch Bo y Plumb- -Sil) If lead silicate sulfate (Dutch Boy Tribase S) is the basic silicate which you suggested for testing, we have this formulation too. However, we are not certain that Tribase E is the one which should be tested, trill you enlighten us on this2 tie should have corresponding information on the white lead and the dry carbonate. Can you supply this information? In the case of the latter two substances, are you interested in the effects of the concentrations employed in paints or in plastic formulations?
