COPY December 13, 1929 Bailey Radium "aboratories East Orange, New Jersey Gentlemen: I have seen a recent bulletin of yours in which you advertise and recormend the internal use of Radium and Meso- Thorium Salts. It is difficult for me to believe that you have not seen reports of the cases in connection with the United States Radium Corporation, in which certain girls claimed to be poisoned due to contact with Radium paint. If you have seen such reports, it is also difficult for me to under- stand how you can offer for sale material claiming to contain Radium and Meso-Thorium Salts to be taken internally. I fully realize that so-called *Radio-active water" containing Radium Emanation has been used frequently in the past and that probably no harm, even if no good, results from such use. The taking internally, however, or Radium or Meso- Thorium Salts certainly should be discontinued until more definite evidence can be obtained one way or the other as re- gards their therapeutic effect. Very sincerely yours, R. B. Moore Dean of Science RBM/LS
