    "ocrText": "UNIVERSITY OF MISSOURI\nCOLUMBIA\nDEPARTMENT OF CHEMISTRY\nMay 5, 1928\nMr. H. H. Barker\nUnited States Radium Corporation\n8:00\nz\n535 Pearl Street\nNew York City\nMy dear Barker:\nEnclosed herewith you will find three copies of manu-\nscript covering the major part of the experimental work which Dr. Flinn\nand I jointly carried out during my recent visit to New York City. The\nthree manuscripts are entitled: The Examination for radio-activity of\n5 Complainants against the United States Radium Corporation; (2) Experi-\nmental Determination of Radium present in Living Persons; and (3) Mis-\ncellaneous experiments conducted in Dr. Flinn's Laboratory, College of\nPhysicians and Surgeons, 168th Street, New York City, April 25, 1928. I\nam also sending a copy of these experiments to Dr. Flinn direct and I am\nsending to him, too, the note-book in which are recorded the original data\nupon which these reports are based. I may add that I have an extra copy\nof each of these reports which will be at your command.\nIt seems to me that we ought to conduct a few experi-\nments to test the photographic action of radioactive bones under the condi-\ntions which Dr. Martin reported. The object of these experiments would\nbe to determine whether the positive effects which Dr. Martin doubtless\nobtained were due to the radioactivity of the sample under test or were\nthe result of pressure and chemical changes occurring during the exposure\nin the calcine bone.\nYou mentioned that you had in discard a Wulf Quartz\nFiber electroscope of the type which we used in our tests and which ha\nbeen out of commission for sometime. . I hope that you will be kind enough\nto forward that to our laboratory and we shall try to introduce some new\nquartz fibers,\nIf you have on hand samples of the ore used by the\nBelgium Syndicate for extracting radium, I would appreciate greatly getting\nsome specimens--not exhigition specimens, but material which we could ac-\ntually use for experimental purposes, run of the mine material. I have a\ngraduate student working for the doctorate degree on the extraction of prot\ninium and some experiments conducted with these Belgium ores would no\ndoubt give us some very important data.\nI hope that you have received the stop watch in a good\ncondition. If there is anything that I can do for you at this time, please\nwrite. In reading the reports you will notice that there are several places\nwhere we suggest additional experiments. I hope that these can be under-\ntaken. With very kind regards, I remain\nSincerely yours,\nHerman Schlundt"
