Fart I, September 30, 1948, a meeting of the representative# of the underwriting companies was held in Hew fast;* The report was favorably reoelvad and It was the general feeling that It was a neat satisfactory and excellent job* It was the feeling of this group that all refer ences to easeer or a--""T should be omitted (Paragraph 75, Page 31 - the intro ductory paragraph trader' "COMPLIGATiaHS" - Paragraph 92, Page 39) f This, request would likewise call far the elimination of axy tables relating to this subject oatter. The group felt that there night be includod under "COHCLUSIOBS" a ^ reference to the non-progressive character of the fibrosis produced by the as O bestos. --------- ----------------------- - -- - f If praetioiblo, they would like to see a more definite atatesent with respect to the sine of the fibres which do the damage* Inquiry was also nsde as V' to' whether there was any relation to the number of fibres per cubic foot of alx. It vas fait that the language in Conclusion D, that is, that a typical fibrosis could bt produced by an atmospheric suspension of asbestos dust containing only "an extremely mail proportion of long fibres" vas too vague and should be de fined more specifically. In addition to the above comments there ere other suggestions which relate more to fas end emphasis} To the extend permitted by the results of the experiments make the "OOHCLUSXGSS" and the introductory "ABSTRACT" more definite, and reduce the of wards whose meanings ere not precise. For example. In the "ABSTRACT"the words "seems", "relatively" , "apparently", "is believed" and in "CQNCLUSIQHB", page 40, the words "primarily", "extremely --n proportion". As far as practicable conform the "ABSTRACT" to "CCSCLUSIQSS". For exuple, "0QHCLUSIQH5" states that "short asbestos fibres do not produce fibrosis'1, vhtrses "ABSTRACT" says that "short fibres are relatively inert". P-MET-329 V' A. -* ft uOMAA. aoos \jr_p&*Lin ajnu N fiMHOtt Where rrrrrlnentii'l result* indicate that asbestos fibre produces a different action than that cessed by fra* silica, Snphasla* these. point* by reference to tha- differences aa, for Instance, partiela size, mechanical rathar than chemical action, acm-progression, and prediepooition to tuberculoid*. In CCOCLOSIOff B, page 41, raferanca la node In tbe fourth line to "oar usual experience" and in the last line, bottom of page, "previous experience". Just vhat was meant by* this reference 'was not clear to the group-end they vould - like to aee that its* clarified. It vaa felt that the report vould be somewhat easier to follow If the. paragraphs dealing vith the various lypes of experixumts vere separated by head ings. For esaaple, Faragrapha 11 to 24 iuclualve, deal vith. the earlyll&g's Float* expert--ate; Paragraphs 2$ to 44 dssl vith tfaa 200 wash material to which vaa added one* part in four of onground notarial; Paragraph* 45 to 57 inclusive, deal with. tb lDOJt ball-milled dust experiments, and. Faragrapha 58 to 76 inclusive, deal with the long fibre experiments, there waa confusion aa to the expsriaanta referred; to In. bob* of tba numbered paragraphs. It would, be helpful, if. th* four rgyiriawnta weri beaded up in scaanmsr other than with the- regularly unshared paragraphs which. precede and follow the*. It was decided that after thee* revisions have been concluded the re port of thee*experimental studies'should be published as promptly as possible, preferably in tha Jmw1 of Sveiena. Asy report an bonen asbestos!* should be separate and not a part of Ibis report. the above oonprisee tbe various eaanents and suggestions which I do not think involves any material ohaags in tfaa report. Please let aa know if you wish any further Information or discussions of tha points raised In this letter. Bast regards* Sincerely yours, 4. J. Laxtaa
