A one-page covering letter of April 18, 1944, from John F. McMahon, managing director of the Industrial Hygiene Foundation of America, to O. H. Cilley, assistant general manager of Raybestos-Manhattan's United States Asbestos Division at Manheim, Pennsylvania, sending the report of the Foundation's recent studies at Manheim, "a part of your continuing dust control program," with extra copies and a bill. McMahon noted that dust samples had been examined by electron microscope, invited questions to W. C. L. Hemeon, the Foundation engineer who did the work, and said the Foundation expected to continue the study once its recommendations were carried out.

What it shows
The study was the engineer's visit that Cilley had arranged in January (Cilley's letter of January 20). The report itself is not in this scan. Cilley quoted its summary and dust counts for Sumner Simpson on May 2 (Cilley's letter): conditions in the Picker House were not satisfactory, while the carding, spinning and twisting departments were under 5 million particles per cubic foot.
