Letters Received to H.H. Barker, July 13, 1931

UNIVERSITY OF MISSOURI COLUMBIA DEPARTMENT OF CHEMISTRY July 13th, 1931. Mr. H. H. Barker United States Radium Corporation 535 Pearl Street New York City, New York JUL 15 1931 My dear Barker: I am glad that you called my attention to the question of reprints of the paper by Failla and myself which is to appear in the August issue of The Journal of Roentgen- ology. I assume that Failla has read the proof and we had an understanding that the man who read the proof was to make the order for reprints. As the matter now stands Failla wants 400 reprints and I have my order in for 100. If you would like to have any considerable number, please advise and I shall increase this order. I shall probably not have oscasion to use more than 50 of these reprints, but our mailing list is gradual- ly increasing and that is the reason I put the number up to 100. My stock of the first paper of this series, by Schlundt, Barker and Flinn, is nearly exhausted. If you have any extra copies on hand, I would appreciate it if you would send me three or four. I may have to call on Dr. Flinn for a few extra copies for I understand that he ordered quite a number. I have sent you a copy of the paper by McGavock, Miss Brown and mysolf on "The Dangers in Handling Radioactive Substances". I am pleased to hear that progress is being made on securing the patent on the application of luminous paint. I sent you several samples of phosphorescent zinc sulfide sometime ago. I think that they represent about the best that we have produced up to this time. I hope that you will find time to make a few neasurements on these for absolute luminosity when activated by known quantities of radium. Probably you have heard that Dr. Miner was taken ill on his vacation trip. He had to go to a hospital at Kingston, New York. Then he was able to travel and he has been in the Cooper Hospital, which I suppose is in Camden br Philadelphia, for fully four weeks now. Just what his trouble is he has not revealed, but it is evidently of a serious nature. He is, how- ever, hopeful; but does not have any idea when he will be able to leave the hospital. When we heard of Mrs. LaPorte's death I wrote to Dr. Martland requesting that he send me a fow samples of the skeleton in case an autopsy had been made; but I have not heard from him in answer to this letter, so I assume that we shall not be able to settle the question of whether or not Mrs. LaPorte was actually radioactive.
