August 28, 1970 Mr 3. F. Heron, Mculdger Chemical Research Department Turner Brothers Asbestos Co., P."0. Box 40 Rochdale, England Ltd. Dear Kip: He have sent to your attention two samples of ashed solids which we have removed from beer. The first of these samples, labeled A97-117-255, represents the solids frm 10 gallons (U.S.) of Schlitz Bottled Draft Beer. Thin sample was given to Dr. Holmes on his recent visit to the Research Center. Part of the manufacturing process for bottled draft beer includes the filtration through a membrane filter. This process is in lieu of pasteurization and yiells a beer with an extremely low solids content. He have fouad, however, that there may be a small amount of asbestos fiber still present in this type of beer. The second sample, which has been mailed to yae, is marked A97 117-269. This is the ashed solids from 1) gallons of Schlitz Lager Beer. Zn this case, we obtained 9.3 millograms of a3h. Zn both these cases, we sent you the entire sample and have not retained any for our use. He did this so that you would have the maximum possible amount to use with your X-ray diffraction technique. He would appreciate it if, after you i.avc cumulated your examination, you could return a small rtior. of each to m: ao that we might exasdna the same solids our two; m.iuos. nv ccvolopea 3 new technique for estimating the total v.-o'.ir.t cf jrateriai . resent on an electron miaroaoope grid. toe.mi.,uu - gives us a more accurate measure -it 'mt ti. * f-Mur' of the earlier point counting method, jivoiv-o t o u > of radioactive tracers (Au 1)6).
