Y. Dear Mr Roder: I am wondering if your crowd have given up all idea of giving me a lump sum for further radium research? I am planning my work for the coming year and if you have decided that you are not going to do anything I will dispose of the animals I now am keeping. Since Miss Dunn has been under my observation, I felt that I ought to carry on 3 one more work. She has a combination of conditions and I am sure her trouble was not due to radium but nevortheless the fact remains that she has about one hundred micrograms of radium in her systom and pieces of hor jaw bone are active. I want to fill the tosth of a group of dogs with your material and then let them live for a number of years taking frequent X-ray pictures and compare them with a normal group. This would be the final answor to the question, tho of course you are through with your legal side. In' following extract of a lettor that I just received may interest you. " He has been using a radio-active material as the cement and root filler for ap- proximately a year with no bad reports. He has not made a scientific chock of these results. To do this, it will be necessary to bring in the patients and make a check on each one by X-ray and objective symptoms. In the cases where he has used the paste or root canal filler, the nerve has been exposed or relatively so and the tooth was aching. Immediately after applying the paste, all discomfort disappeared and no bad results have bsen reported. W realize that possibly not sufficient time has slapsed for him to determine whether there is to be any bad aftor effects. & T is paste is a mixture of zinc sulphide and radium. I estimate I can carry on this research if I can get @. lymp sum of $2000.00 it will see me through all that I want to do. Yours truly Inden Is B. Flamie
