NEW YORK OFFICE September 12, 1945 SEDEROSIS L. E. Hamlin, M. D. Director, Medical Department Chicago I have just gotten around to reading the July issue of the INDUSTRIAL HYGIENE DIGEST and I was very interested in Item 862 quoting from a recent article in the J.A.H.A. by Drs. Pendergrass and Leopold on the subject of "Benign Pneumoconiosis". This article probably would be valuable ammunition to have in our files for. the future.
