J. Dr. Robert C. Reynolds Department Earth Sciences Dartmouth College Hanover New Hampshire 03755 ' . @ Dear Bob Enclosed please find four 4 samples of talc labeled STD C D E and F which I am sending as a result of our discussion concerning a possible concentration technique for chrysotile in tale Each sample is approximately 5 gram and contains less than 0.5 by weighotf chrysotile with the exception of STD E which contains less than 0.5 of the platy serpentine mineral antigorite I thought it would be interesting to determine whether the morphology of the serpentine mineral had any effect on the efficiency of the separation In addition STD C and D each contain less than 0.1 tremolite It was a pleasure talking with you on December 13 We plan to try your actinolite concentration technique soon Our best wishes for a Happy Holiday Season Sincerely : a Jack 1 Jaclk ab John P.
