Aa our Nr. Wheeler haa told you previously, Nenaanto la vary oonoaraad about tha reported preaence of poly chlorinated blphanyla In conjunction with peraiatent chlorinated hydrocarton raalduaa.

On page four of your article to be aubaltted for publication* you refer to tha work of Or. Melga re ported In tha April* 1954 Journal of tha Aaarlean Medical Aaaoclatlon. X thought you night bo Inter acted In coplaa of tha exchange of corraapondanca which X had with Sr. Nelga at that tine. To our knowledge there have not bean eaaea reported in the literature einee Dr. Melga' article which support the oosBMnt that eaaea of ohloraone have been reported repeatedly.

In view of the present circumstances, perhaps wa are fortunate that suoh proposed application never developed to any extent as a uss for the Aroolors. Interestingly, this comment is applicable to many of the proposed or ' suggested possible uses for the Aroclors as presented In our technloal and sales literature. Again, may I express ray appreciation for the opportunity to study the excellent report of your findings and your objective review of the literature. Sincerely, REKtJu c.c. J. S. Metcalf R.
