TREASURY DEPARTMENT BUREAU OF THE PUBLIC HEALTH SERVICE OFFICE OF INDUSTRIAL HYGIENE WASHINGTON, D. C. 2221931 IAA AND SANITATION Room 1-123, "C" Bldg., 16 Seventh St., S. W. May 21, 1931 Mr. H. H. Barker, Vice President, United States Radium Corporation, 535 Pearl St., New York, N. Y. Dear Mr. Barker: Your letter of May 20th received. As far as I know, there is no reason why the gamma-ray electroscope which you SO very kindly loaned us should not be returned to you. However, both Dr. Leake and Mr. Knowles are away from the office at this time and I will take the matter up with them and write you again within a few days. Your great kindness and courtesy in lending this instrument, which has been of the greatest value to us in our studies, has, I assure you, been very much appreciated by the Public Health Service. Yours sincerely, James E was (James E. Ives) Physicist
