Vandiver Brown to Leroy U. Gardner Agreeing to Extend the Dust Exposures (1941)

A one-page letter of November 7, 1941, from Vandiver Brown, Johns-Manville's secretary, to Dr. Leroy U. Gardner of Saranac Laboratory, with a copy to Sumner Simpson of Raybestos-Manhattan. Brown was glad the asbestos experiments were "nearing completion," accepted that much work remained on "the mass of data assembled during these five years before the definitive report can be expected," and wrote that continuing part of the experiments in one dust room a few months into the next year was "entirely agreeable to us."
