4 Sydney, N.S.W. AustraIia Dear Mr. Weeks: This is in response to your TWX of January 3, 1973 relative to information on asbestos toxicology. The pyrogenic silica suppliers have engaged in the same kind of down-grading approach in this country, Japan, and Europe with very limited success. Several of their customers have asked them to put their allegations in writing; which, so far, they have declined to do. This has not helped their credi bility; and at least in a few instances has turned customers to us. It is difficult to present the whole picture of. the asbestos toxicology controversy in a letter of reasonable length. We also do not know which particular questions have been emphasized. We have, therefore, provided information on the main questions that have come up. This information has been attached as a separate package. It is suggested, however, that you select from it only the parts needed to satisfy the customer rather than hand it out as is. This avoids raising questions which may not come up. The response to a Via II Street Journal article is enclosed for general information. It may also be useful for you to know that Dr, H. B. Rhodes and Mr. B. L. Ingalls of this office met Warwick Williams and Graham Porter of Polymer Corporation last year at the SP1 meeting in Washington. They spent considerable time with them. This year's meeting is in early February. If you would like us to meet with either of these gentlemen or their representative please let me know. Assuming that I visit Australia the week of March 5th or 12, I would like to visit all customers who have toxicology questions. I will probably have the equipment necessary to obtain a limited amount of dust samples. You may want to schedule customer visits for this purpose. /**- r -- .It UCASB01410768 Mr. P. C.
