Letters Sent to Dr. Cecil K. Drinker, April 30, 1924

April 30, 1924. Dr. Cecil K. Drinker, Harvord University School of Public Health, 55 Van Dyke St., Boston, Mass. Dear Dr. Drinker:- Your letter of April 29 to Mr. Viedt is most interesting. I am glad to have a copy. Since you will be here for two days next weck, we will have ample opportunity for discussion and I con see from your note that my Toosday evening suggestion is out of order. There have undoubtedly been many disastrous results from contimious exposure to X-Rays. We have yet to hear of a case of Radixum buzn developing malignancy. Generally speaking, it is an accepted fact that Radium in concentrated doses destroys tissue, particularly malignant or scar tissue. which has only about one-guarter the resistance of healthy tissue. On the other hand, bone structure has been showm to be one hundred times as resistant to Radium action as malignant growths, soft organs, etc. On the other hand, Radivm in small doses is a stimulant. It is extensively used intravenously for various purposes. The water in health springs is generally radioactive. We have just received from the printer a pamphlet of abstracts from the literature covering the internal therapy of Radium. I am sending a copy of this under separate cover, also an outline of Radium and its emanation, a booldet propared by the National Radium Products Company of New York. I think these will be of unnsual interest to you. I am particularly interested to hear the results that you will have testing radioactive zine in the blood stream of animals. I notice your letters are addressed to *Albert" Roeder. My front name is "Arthur" I should have told you this or given you a card when you were here. Cordially, President.
