100 PROCEEDINGS OF THE EEGENTS. 



Royal Academy of Moral and Political 



Science of Madrid, Madrid., July 10, 1861. 



This Royal Academy, being impressed with the fact that nothing 

 contributes more efficiently to the adyancement and propagation of 

 moral and political science than a frequent communication with per- 

 sons deyoted to its cultiyation, has resolyed to invite to a reciprocal 

 correspondence all the principal learned bodies, whether national or 

 foreign, whose studies or inyestigations are analogous to those of this 

 Institute. 



As this Academy is the most modern it is proper that it should pro- 

 pose the commerce of the ideas and theories necessary to the progress 

 of moral and political science. And it does not hesitate an instant 

 in sending to your Institution the account of its own commencement 

 and organization, as well as the publications that haye marked its 

 short life. 



The credit which your Institution has acquired for taking so much 

 interest in all thatfayors the adyancement of ciyilization and improye- 

 ment of the people, inspires the Academy of Madrid with confidence 

 that its wishes will be accomplished, and that the illustrious body to 

 which it directs itself to-day will honor it with its correspondence, and 

 accept the exchange of memorials or other works which haye been 

 or will be published in future.
