Letters Received to H.H. Barker, December 21, 1931

UNIVERSITY OF MISSOURI DEC 23 1931 COLUMBIA DEPARTMENT OF CHEMISTRY December 21, 1931. Mr. H. H. Barker United States Radium Corporation 535 Pearl Street New York City My dear Barker: I wish to thank you for your prompt response to our request for funds to carry on the radium refining work. The boys are making very good progress with the sodium hydroxide fusions and I think we have finally solved the treatment of this obstreperous material. Please be advised that Mr. Armstrong has done everything that he can to arrange for our visit to Elgin. We have written him that we ex- pect to be on hand early Monday morning, December 28th. We expect to go by train to Chicago and Mr. Armstrong will probably accompany us to Elgin. In case the weather is clear, and looks steady, we may take the car and go directly to Elgin without going to Chicago. I shall keep Mr. Armstrong posted as to our plans. We have heard from Dr. Flinn; he is sending us two ionization chambers, one with very small natural drift and another which is rather high. I asked him to sond the second one for I have hopes that I may give this chamber a little treatment and restore it to its normal natural drift. Our gamma ray instrument has a very small natural drift, only about .1 the drift that your instrument has under its best working conditions. We thus anticipate no difficulties in making the measurements. Mr. . Armstrong writes that there aro several physicians in Chicago who would like to have some tests made on some of their patients, and I hope that we can find time to do this; we shall be free to give the entire week to the work but it will be necessary for me to be back here in Columbia on Sunday, January 3d. Wishing you g. Merry Christmas and ex- tending my good wishes to Mr. Lee, I remain, Sincerely yours, Herman Schlendt hs.as Herman Schlundt.
