Bryant PI.S'Jl V/. Kuhn wkuhk S. Second Street I have asked Jim Sullivan to order 5 gal. each of the chlorinated naphthalene series containing from 1 to 8 chlorine atoms. Seme of the chlorinated naphthalenes could he fed to chickens and the tissue extracted to see if these compounds elute in the GLC at the same positions as Aroclor. I understand you plan to run DDT, Aroclor, Toxaphene and Cl naphthalene. Are there any other likely candidates of a similar chemical natui'e? W. R. Richard ms 0631233 PCB-ARCH0745679
