Lois Gaul's Manville Memos on Hope, Hanna and Stallybrass's Industrial Hygiene and Medicine (1985)

Two one-page Manville memos of March 12, 1985, by Lois Gaul, who was reading older medical and industrial hygiene texts for the company. Both concern Industrial Hygiene and Medicine by E. W. Hope, W. Hanna and C. O. Stallybrass (London, 1923). The first, to Dr. Paul Kotin, quotes the book's definition: "phthisis is now understood to mean tuberculosis of the lungs with cavity formation, and the term 'miners' phthisis' is confined to a condition of the lung in which tuberculosis is added to a fibrosis." The second, to file, notes that the book is in the library of the Philadelphia College of Physicians and that, although it has a chapter on "Dust as a Cause of Disease," it "is not relevant to asbestos or to the government litigation."
