Mr. H.H. Barker, United States Radium Corporation, 535 Pearl Street, New York City. Dear Mr. Barker: At last I am going to write to you on a more pleasant subject. € One of the doctors here has a case in which he has asked me to produce a low grade radium poisoning, "blood poisoning. 11 What he really wants is to treat the patient with radium chloride so as to assist in the elimination of calcium from the body. We expect to make a complete study of the case including the elimination, storage, and blood chemistry. Will you tell me what size ampules you usually put up for the medical profession, also if you put any solutions similar to the rado-thor which Baily is putting up? It is my feeling that we will inject ten micrograms of radium chloride into the patient and then every so often, say once in ten days give her one or two micrograms of the salt by mouth. Have you any special literature besides what I have indicating how the treatment has been carried on in the profession? This case is one in which there has been excessive calcium deposition since birth and I think it will be interesting to watch the effect if any from the internal treatment from radium. How do you charge the profession for such ampules as the order will go througn Presbyterian Hospital Purchasing Department, and how soon if they decide to treat the patient this way could we get such ampules. Dr. Murray is now in the middle west and will be back in about ten days. On his return we expect to decide definitely how to handle the case. With best regards, I am Very truly yours, Funden is B.Thin Frederick B. Flinn Director Industrial Hygiene.
