I. To DIFFUSE Knowledge. — It is proposed to publish a series of reports, giving 

 an account of the new discoveries in science, and of the changes made from 

 year to year in all branches of knoivledge not strictly professional. 



1. Some of these reports may be published annually, others at longer 

 intervals, as the income of the Institution or the changes in the branches of 

 knowledge may indicate. 



2. The reports are to be prepared by collaborators eminent in the different 

 branches of knowledge. 



3. Each collaborator to be furnished with the journals and publications, 

 domestic and foreign, necessary to the compilation of his report; to be paid a 

 certain sum for his labors, and to be named on the title-page of the report. 



4. The reports to be published in separate parts, so that persons interested 

 in a particular branch can procure the parts relating to it without purchasing 



the whole. 



5. These reports may be presented to Congress for partial distribution, 

 the remaining copies to be given to literary and scientific institutions and sold 

 to individuals for a moderate price.
