! April 8, 1969 Dr. Joseph C. Calandra Industrial Bio-Teat Laboratories, Inc. 1810 Frontage Road Northbrook, IlllnolB 60062 Dear Joe: Confirming our telephone conversation, I have enclosed a number of items including the Itinerary for the trip to Europe. As Indicated Marlon and I will meet Bob Keller In London on Friday, April 25 Bill Richard will also be in Europe but will meet Bob and me In Brussels on May 1 and accompany us to Stockholm. I don't believe Bill will make the Amsterdam or Dusseldorf visit. I have enclosed a copy of a letter from Prof, van Oenderen in the Netherlands and my reply. There is also enclosed a copy of the reports from Drs. Hehler and Metcalf. Perhaps I should say these are "notes" on. their meetings with all of us in your lab rather than "reports" Copies of these three items are being sent to Otis Fancher. I think the copy of my correspondence with J. W. Barrett, Director of Research for Monsanto in Europe and to Wldraark indicate the people we would like to call on in Oreat Britain and Sweden. In one of the earlier letters from Widraark he indicated that a Prof. Bo Kolmstedt at the Karollnska Instltutet was involved in PCB toxicology studies. It sure would be fortunate and very pleasant if your proposed trip to Europe would allow you to join us on any of the calls or for the whole itinerary. Best personal regards. Sincerely, BPWjcJs bcci W. r. Richard R. E. Keller Enclosures Elmer P. Wheeler Manager, Environmental Health DSW 034373 ^ \-' STLCOPCB4018200
