RECFIVED Columbia Unitersitp 1925 Unllege nf and Surgeons 437 WEST 59TH STREET, NEW YORK DEPARTMENT OF PHYSIOLOGY July I5 1925 Mr A. Roeder, United States Radium Corporation, New York City, N.Y. Dear Mr. Roeder: UNITED BTATES RADIUM GORP. I have delayed answering your letter of July cause my time has been taken up pretty well this whole week. If it is agreeable to you I will drop in on you Friday afternoon or any other time you may suggest. You can call me up on the telephone any time in the morning as I am in usually after 9.30. I have no special report to make. The animals are all normal and are not showing any signs of any ill efect. By next Tuesday I will be ready to take some more samples out to Dr Barker. These samples will give us some idea as to the rate of elimination and the distribution of the remaining radium in the body. We will not examine the girls in Connecticutt until the middle of August so that the effect of their vacation will have worn off. I wrote to Switzerland for some data, but so far have not heard from them. Sincerely yours Funden, In B. Villin
