In accordance with a request of the Chilean 

 government, transmitted through the cus- 

 tomary diplomatic channels, the commissioner 

 of education calls attention to the announce- 

 ment of an Exposition of Fine Arts to be 



opened at Santiago, Chile, on September 18, 

 1910, as a feature of the Chilean centennial. 

 This e.xposition will be held in the recently 

 erected Palace of Fine Arts which will form 

 a permanent memorial of the occasion. Works 

 of art intended for this exposition must be 

 forwarded before the first of May of the pres- 

 ent year. Full particulars with respect to the 

 plans for the exposition may be obtained by 

 addressing the general secretary, Mr. Ruchon 

 Brunet, Santiago, Chile. 



The London correspondent of the Journal 

 of the American Medical Association writes 

 that the prohibitive price of radium has led 

 to the establishment of a novel institution — a 

 radium bank where the precious metal may be 

 stored and rented to physicians, scientists and 

 others who wish to use it but can not afford to 

 pay $80 a milligram, its present market price. 

 The ultimate locality of the bank is to be in 

 the neighborhood of Cavendish Square, in the 

 heart of the district in which London consul- 

 tants live, but for the present temporary offices 

 have been opened at Moorgate street in the 

 heart of the commercial and banking district 

 of the city. For an average operation 50 milli- 

 grams of radium are required, costing $4,000 

 and, therefore, it is only at one or two of the 

 London hospitals that radium can be used to 

 any extent. A number of business men have 

 combined to form the bank which will " let " 

 100 milligrams at $200 for one day's use and 

 for each subsequent day at one half per cent, 

 on the value of the amount issued. Securities 

 win have to be given. The bank purposes to 

 stock radium to the value of $250,000. The 

 difficulty is in getting a supply of radium. 

 The main source has been the pitch-blende 

 from Joachimsthal, Bohemia, which yields one 

 part in 3,000,000. A new supply has been dis- 

 covered in the bed of a stream near Guarda in 

 Portugal. In England two Cornish mines 

 have yielded a little but the whole available 

 supply is limited owing to the enormous ex- 

 pense of extraction. Although radium exists 

 in air, sea water and almost everywhere, there 

 is hardly an ounce of the pure metal in the 

 world. The bank will be organized very much
