He said that you had been in contact with him. 1 am not trying to cause the talc industry any problems. 1 think lack of know ledge is a more serious problem. 1 have been told by the Industrial Hygienist that consults for this institution that all talc contains asbestos and we should not use any products containing talc. The reason I have carried out this study is that 1 am asked to analyze very pure talcs for amphiboles. I takes a great deal of time to 4S 11 v, lo it not le t it is na tit had i' fet. Co ^0Q ** to l0Q0 an way, and to establish the validity of a method it is necessary to publish it for peer review; That is why the paper has appeared in print. Even if I use the old method, the new one is useful to give me an idea of how much effort will be needed to do the analysis to the accuracy required. As 1 told Slim Thompson I have analyzed many talc samples (only a few reported) and often blind, in that I did not know their sources at the time the analyses were done. 1 do not believe I am misrepresenting these talcs. For individual deposits, the shape distribution and quantity remains fairly constant over time. Sincerely yours, PLAINTIFF'S e EXHIBIT J Alice M.

I have been cold by the Industrial Hygienist that consults for this institution that all talc contains asbestos and wo should not use any products containing talc. The reason I have curried out this study is that 1 am asked to analyze v d y pure talcs for amphiholes. I takes a great deal of time to do 100 fields of view. Sometimes it is necessary to go to 1000 f.o.v. It is not fun! It scented to iae that there had to be an easier way, and to establish Lhe validity of a method it is necessary to publish it for peer review. That is why the paper has appeared in print. Even if 1 use the old method, the new one is useful to give me an idea of how much effort will be needed to do the analysis to the accuracy required. As 1 (.old Slim Thompson 1 have analyzed many talc samples (only a few reported) and often blind, in that I did not know thoir sources at the time the analyses were done. 1 do not believe I am misrepresenting these talcs.
