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 inall 

 branches of knowledge not strictly professional. 



1. These reports will diffuse a kind of knowledge generally interesting, 

 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 dif- 

 ferent 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 pur- 

 chasing 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. 



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



reports. 



I. PHYSICAL CLASS. 



1. Physics, including astronomy, natural philosophy, chemistry, and 

 meteorology. 



2. Natural history, including botany, zoology, geology, (fee. 



3. Agriculture. 



4. Application of science to arts.
