Mr. H. H. Barker, APR 111932 United States Radium Corp New York, N.Y. Dear Mr. Barker: I sm enclosing my report on the last test on Mrs Maddinger. This test was more satisfactory that the one made earlior. But it leaves much to be explained. As you notice the test made with the instrument in back and in front agree very well which is quite different from the last time. They confirm more or less my test of 1929. Also I am sure are the correct determinations for if she had the quantity I found on Feb 25th hor jaw would have been pone completely by this time if my experience is worth anything. As you are fully aware the tests I made at that time were carefully conducted and the explanation must lie in sone- thing outside of my office. Yours truly Frederick B. Flinn indicid B. Flem
