UNIVERSITY OF MISSOURI COLUMBIA DEPARTMENT OF CHEMISTRY -2- Mr. H. H. Barker Duyn Case 5 micrograms per gram which is a value nearly 20 times that of our value. To use nitric acid to dissolve the residue. I know that you will keep me advised about the progress of the plans for the tests. It seems to me we had better send the spinthariscope and sample of zinc sulfide directly to Dr. Flinn so as to avoid a chance for contanination in your office. In case we find the girls active by the gamma ray method of testing, would it not be advisable to check the results against the expired air using the large Lind ionization chamber? With very kind regards, I remain Sincerely yours, Herman Schlundt Herman Schlundt. we shall also send Dr. Flein HS samples of the two grades of phosphoresent gns for making new screens. b Have just discovered that one of the three which you cent is an exhibition in strument. up to this time we had confined our tests to the two of the instruments, and had left the third in boy unt rached many thanks for this present HS
