 to preserve and use the same for the benefit of students, or return 

 them without unnecessary delay to the academy : to afford to all 

 special students who manifest an earnest desire to 'study science, 

 the opportunity of doing so free of charge for tuition. 



2. " To promote a knowledge of the sciences among the people,'' 

 it is proposed to give courses of lectures to public audiences ; to
