Letters Sent to Dr. Herman Schlundt, July 24, 1930

July 24th,1930. Dr. Herman Schlundt, 303 Hicks Ave. 9 Columbia, Mo. Dear Dr. Schlundt: It seems that the letter which you dictated on Friday, relative to information you desired as to the tests on lrs. McDonald, conducted by you and Dr.Flinn in New York, has not arrived at our office. The information which I am giving you is talcen from report of test conducted by you at the Hotel Marseilles November 19th to 21st,1928. The radium equivalent by expired air was 8 micrograms and the gamma ray activity 5 microgram giving a total activity of 13 micrograns. The constant used for the garma ray machine was 8.6 x 10-5. I think that this is the information you desire. Mr. Smith has not definitely decided whether he wishes a re-examination of lirs. Tuck and Mrs. Metz, as yet, but I hope to have some final word from him during the next few days. In a recent conversation with Dr.Humhries he indicated that one of these girls never used a brush in in the application of luminous material to watch dials. Obviously this must have been Metz, and it is quite probable that upon ro-examination we might find that she is not active. trip back to New York was very hot and dirty, but since my return we have had a couple of nice rains and at the present our weather is very delightful. Sincgrely yours, Vice President. HRBarker: :RH
