DETAILS OF THE PLAN FOR DIFFUSING KNOWLEDGE. 



I. By the publication of 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 knowledge not strictly professional.* 

 1. These reports will diffuse a kind of knowledge generally in- 

 teresting; but which at present is inaccessible to the public. Some 

 of the 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 publi- 

 cations, 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 distri- 

 bution, the remaining copies to be given to literary and scientific 

 institutions, and sold to individuals for a moderate price, f 



* This part of the plan has been but partially carried out. 



t The following are some of the subjects which may be embraced in the reports: 



I. PHYSICAL CLASS. 1. Physics, including astronomy, natural philosophy, chem- 

 istry, and meteorology. 2. Natural history, including botany, zoology, geology, &c. 

 3. Agriculture. 4. Application of science to arts. 



II. MORAL AND POLITICAL CLASS. 5. Ethnology, including particular his-, 

 tory, comparative philology, antiquities, &c. 6. Statistics and political economy. 

 7. Mental and moral philosophy. 8. A survey of the political events of the world; 

 penal reform, &c. 



III. LITERATURE AND THE FINE ARTS. 9. Modern literature. 10. The fine arts, 

 and their application to the useful arts. 11. Bibliography. 12. Obituary notices of
