REPORTS OF THE SECRETARY OF THE SMITHSONIAN 

 INSTITUTION, FROM 1847 TO 1853. 



To make the operations of the Institution more generally known, it has been thought ad- 

 visable to append to this Report, for reprinting, the several Annual Reports of the Secretary. 

 They give a connected history of all the operations of the Institution, from its organization 

 to the end of the year 1852. These Reports exhibit the fact that very little change has been 

 made in the plan of active operations originally adopted, and that all the anticipations which 

 were entertained in regard to it have been fully realized.
