Dr. J 0Po Simko Colgate Palmolive 909 River Road Piscataway, New Jersey 08854 Dear Dr. Simko: Using transmission electron microscopy and selected area diffraction we have examined a sample of talc designated as 4915. In this talc we found one fiber of tremolite approximately 2 micrometers by l/2 micrometer. Using selected area diffraction and zone analysis to give the angles between spots we positively identified this as tremolite. We examined a further preparation from this sample and found no other tremolite. This particular fiber would not represent more than a few parts per million, less than 5 parts per million of asbestiform minerals and certainly may well just be stray contamination. Thank you for consulting MeCrone Associates, if there are any further questions concerning this report or the data contained therein please feel free to contact me. , GRG:jd Ref.
