take place. Within a year at most, the mill Operations should make 

 results certain and the extraction of ore and production o£ radium 

 will then be continued on a larger scale. The Separation of uranium 

 and Vanadium will also be studied, a contract having already been 

 signed for all of these by-products that may be obtained. All proc- 

 esses, details of apparatus and plant, and general information gained 

 will be published for the benefit of the people. 



The institute is supplied with sufficient funds to carry out its 

 plans. It has been formed for the special purpose of procuring 

 enough radium to conduct extensive experiments in radium therapy 

 with special reference to the curing of Cancer. It also expects to 

 carry on investigations regarding the physical characteristics and 

 chemical effects of radium rays and hopes in time to be able to assist 

 or perhaps even duplicate the effects of these rays by physical means. 



Actual experience, especially of the institute's president, in the 

 application of the 650 mg. of radium and 100 mg. of mesothorium 

 already in his possession, have led him and his associates to believe 

 that with larger supplies many of the variables that can not now be 

 controlled may be f ully correlated, and that radium may become the 

 most effective agent for the treatment of Cancer and certain other 

 malignant diseases. Important results have already been obtained 

 by using high concentration of the gamma rays of radium with the 

 alpha rays entirely cut off and the beta rays largely eliminated. 

 Hospital facilities in both Baltimore and New York are already 

 supplied. (Charles L. Parsons: Address to the i6th Annual

Important discoveries at the Radium Inst., London. From 

 the Radium Inst, some important discoveries in radium therapy are 

 announced. At the Inst, it has been demonstrated that radium 

 emanation has exactly the same properties as pure radium and is as 

 efficient for curative purposes. This is a discovery of the highest 

 practical importance, for previously radium treatment could be 

 given only at the Inst., as it was not practicable to lend this ex- 

 tremely valuable and limited substance. Now the emanation fixed 

 in a hollow plate or tube, is sent to physicians for use on patients. 

 Thus, if a physician wants 200 mg. of radium for use on a patient,
