1. The objects, and the amount appropriated, to be recommended by counsellors 

 of the Institution. 



2. Appropriations in different years to different objects ; so that in course of 

 time, each branch of knowledge may receive a share,

I. To DIFFUSE Knowledge. — It is proposed to pid)lyjj^ 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. 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.
