SCIENCE 



397 



tiition was demonstrated during the World 

 War by the existence of the American Uni- 

 versity experimental station. 



The Bureau of Foreign and Domestic Com- 

 merce, in cooperation with the Bureau of 

 Mines, has completed arrangements to produce 

 in this country motion picture films showing 

 methods of production and emplo^Tuent of 

 American machinery and similar products. The 

 actual cost of the photography, as well as the 

 expenses incurred in the making of additional 

 prints of the films, is borne by the cooperating 

 company. After the picture has been com- 

 pleted and approved, the work of distributing 

 the films, both in this country and abroad, is 

 taken care of by the Bureau of Foreign and 

 Domestic Commerce without any further ex- 

 pense to the company. 



Further information in regard to radium in 

 the Congo is quoted from the bulletin of the 

 Belgian Chemical Society to the effect that the 

 sample of minerals assayed by Professor 

 Schoep of the University of Ghent yield 424 kg. 

 of uranium and 139 mg. of radium to the ton. 

 The minerals came from the Upper Katanga, 

 in the concession of the Union Miniere which 

 has entrusted the industrial treatment of the 

 uranium to the Belgian Societe Generate Metal- 

 lurgique de Hoboken, which has put up a fac- 

 tory for the purpose in the Antwerp district. 

 Other deposits of the same minerals have been 

 found at other points specified, and Professor 

 Schoep has found two new kinds of minerals 

 among them, extremely radioactive. He has 

 named one "curite" and the other "kasolite," 

 and announces that the crystals are soluble in 

 nitric acid, and the radium salt can then be 

 extracted from the fluid without passing 

 through the usual calcination process. 



IiiPROVEMEKTS of the wireless plant at the 

 University of Iowa have increased the range 

 of station 9YA to 1,000 miles under average 

 conditions and 2,000 miles when conditions are 

 favorable. The university is now broadcasting 

 regular weekly programs under the direction 

 of the extension division. Besides the regular 

 programs all noteworthy happenings on the 

 university schedule are broadcasted as they 

 take place. Thus far nothing of a strictly edu- 



cational nature has been attempted, the pro- 

 grams being arranged with entertainment 

 rather than instruction in view. 



Dr. Henry Noeris Russell, professor of 

 astronomy, Princeton University; Dr. Robert 

 A. Millikan, of Chicago, head of the Norman 

 Bridge Laboratory, California Institute of 

 Technology; Mr. Charles W. Brown, professor 

 of geology. Brown Universitj', and Dr. Gilbert 

 N. Lewis, professor of physics, University of 

 California, have completed a series of lectures 

 at Pomona College, covering recent advances 

 in physical science. Their subjects were: "The 

 evolution of the stars," "Modern atomic the- 

 ories," "The energy, composition and structure 

 of the earth," and "The chemistry of the stars." 



The annual meeting of the Nebraska Acad- 

 emy of Science will be held at Nebraska Wes- 

 leyan University on April 21 and 22. On the 

 evening of April 21 Dr. G. W. Stewart, of the 

 University of Iowa will deliver an address on 

 "Achievement in science." Weather permitting, 

 this will be broadcasted by radio-phone. The 

 annual address of the jsresident. Professor J. C. 

 Jensen, will be delivered at the general session 

 on Saturday morning, the subject being "Re- 

 cent research in atomic structure." In addition 

 to a large number of papers, plans have been 

 made for the showing of twelve reels of the 

 finest scientific motion pictures available, and 

 six or seven large manufacturers of scientific 

 apparatus have agreed to send some of their 

 latest models for exhibition. 



At the regular meeting of the Biological 

 Society of Washington, to be held on April 29, 

 at 8 p.m., at the Cosmos Club, Washington, 

 D. C, Dr. William E. Rifcter, of the Scripps 

 Institixtion for Biological Research, will ad- 

 dress the society on "The usefulness and the 

 peril of laboratory methods in biology." 



UNIVERSITY AND EDUCATIONAL 

 NOTES 



McPherson College, MePherson, Kansas, is 

 building a four story science hall modern in 

 every way. The estimated cost is $160,000. It 

 is expected to be completed by August. 



A CONTRACT has been let for a new medical 

 building at the Universitv of Alabama, Tusea-
