 vals, 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.

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

 particular branch can procure the parts relating to it without purchasing the whole.
