Letters Sent to Dr. Frederick B. Flinn, February 9, 1931

February 9,1931. Dr. Frederick B. Flinn, College of Physicians & Surgeons, 632 W. 168th St., N.Y.C. Dear Dr. Flinn: We are glad to advise you that we stock ampoules containing 5, 10, 25 and 50 micrograms of radium element in 2 ce sodium chloride solution for intravenous injection. These ampoules are sold to the medical profession on a basis of 204 per microgram of radium element contained, with a discount to druggists and hospitals of 50 % While we do not stock a radium solution for oral use, still we are prepared to make up such solution on order, and in this connection would be glad to prepare such a solution as you might elect to prescribe for the patient in question. The solution which we would put up would differ from that of Bailey's as our solution would contain radium only, while Radithor was a combination of radium and mesothorium. It is my recollection that you have practi- cally all the literature on this subject. There has been nothing occurring recently which is of importance. lie shall be glad to cooperate with you in any way that we can to meet your requirements in the treatment of this patient. With kind regards, I am Sincerely yours, Vice President. HHBarker: RH
