Letters Received to H.H. Barker, May 13, 1930

UNIVERSITY OF MISSOURI COLUMBIA DEPARTMENT OF CHEMISTRY May 13, 1930 Dr. H. H. Barker U. S. Radium Corporation 535 Pearl Street New York Dear Dr. Barker: In reply to your question whether or not I can participate in making electroscopical examination for radioactivity of two or three girls whose cases will probably come up in the courts, or settlement through Dr. Flinn, let me say that I shall be glad to come on soon after the close of our regular session which will be on June 3rd. In this connection let me mention an item which may be of interest to you in arranging the date for this examination. A week or two ago I had a note from Dr. Failla stating that there would probably be in the near future a meeting of the Advisory Committee for U. S. Public Health Survey of Radium Dial Painters. Perhaps you could get in touch with Dr. Failla with a view of getting some information concerning the probability of this conference. By arranging a time for the exam- ination of the cases which would come close to this date, we would save both time and expense. A few more words with regard to the Mesothorium situation. The Lindsey Light Company's Mesothorium concentrates are not being consolidated with the Welsbach supply and I think that a year or more has elapsed since the Lindsey Light Company disposed of its supply which I understand is now being shipped abroad. Monazite sand is being treated, however, in the East for the manufacture of Thorium Nitrate and there is a possibility that this new source of supply of Mesothorium will be refined in this country. I hope to have a little further information on this sub ject by the time I come to New York. In short, then, you may count on my presence in making the tests and I hope that you will take steps towards fixing the date. With very good wishes and kind regards, I remain Yours very truly Herman Schlindt HS/GMA Herman Schlundt
