Letters Received to H.H. Barker, September 14, 1931

UNIVERSITY OF MISSOURI COLUMBIA DEPARTMENT OF CHEMISTRY September 14th, 1931. SEP 16 1931 Mr. H. H. Barker United States Radium Corporation 535 Pearl Street New York City My dear Barker: I had a talk with Horace Thomas who is conducting the experiments on the administra- tion of radium to rats and he reports that the colony is still thriving but there are somo indi- cations now that the radium is having an effect on the boney skeleton. The last time he injected radium solution some of the rats put up a little struggle and in this way two of them had a frac- ture of bone in the leg. He is, however, planning to continue a little while longer and hopes now to mate a pair of the radioactive rats to ses if there will be any transmission of radium to the offspring. The entire colony has come through the summer heat and I hope it will survive the hot spell we are now enduring. We need another shipment of about 20 5-microgram ampoules of radium solution to carry send 9/16/31 forward the experiments. WHB With very kind regards, I remain, Sincerely yours, Herman Edward Herman Schlundt. hs.as
