Dear M r . Champlin :
I am sending you herewith two copies of Mr. Cholak's report
of his findings on the samples which you provided m e , in
accordance with your letter of September '22* I am sending
these results without comment, partly because I am to be away
for a number of days, and there is not time to give the
matter any further thought, but mainly because all of the
information that you are likely to require has been given by
Mr. Cholak. If there are any questions in your mind concerning
the results, I suggest that you get in touch with him by
telephone.

Very truly yours,
