Nature says that under the name of the 

 ' Potentia Organization,' an international asso- 

 ciation has been formed with the object of 

 establishing among nations a mutual relation- 

 ship and cooperation for the diffusion of ac- 

 curate information and unbiased opinion con- 

 cerning international events and movements, 

 and to combat narrow, prejudiced, and often 

 interested views and news that contribute so 

 much to international mistrust and misunder- 

 standing. It is proposed to publish through- 

 out the world, through the medium of news- 

 papers and reviews, statements of simp'e fact 

 and expressions of opinion by eminent public 

 men of all nations on all important political, 

 social, philosophical, economic, scientific and 

 artistic questions, to present the sincere views 

 of experts on all current international events, 



and to refute false or biased news and views 

 calculated to spread error and to endanger 

 the peace and progress of the world.
