Newark, New Jersey July 17, 1961 TOXICITY OP FLAKE PIGMENTS RE: Telephone conversation, J.W. Clayton, Jr. - B.H. Perkins 7/14/61 We are sending to Miss Hood via Company mail, two Sandies of flake pigments for inhalation toxicity determinations, in accordance with our telephone conversation. The samples are coded as follows: *97% (A) NF-103-D Lot 12916 100 grams Pigment contains small amount of a Sb compound. if?f (A) NF-105-D Lot 12939 100 grams Pigment contains small amount of a Cr compound. Details are given on the forms being sent to Miss Hood. It is our understanding that these samples will be tested by the procedures used with the previous flake pigment samples we submitted. Test of these samples will conp lete the program we plan. It is our Tinderstanding that little remains of the $2,000 provided by project &'?%-MR-585-and that you will prepare another project to cover the approximately $850 estimated for evaluation of the two samples being submitted with this letter* BHPsdc H.
