The following preamble and resolutions, offered by Dr. 

 Morton, were adopted : 



Whereas, Dr. Thomas B. Wilson has made this institution 

 the depository of his magnificent collection of Birds, which, 

 from the number, beauty and variety of its specimens, al- 

 ready ranks as the fourth extant ; and 



Wliereas, Dr. Wilson is assiduously extending and perfect- 

 ing this collection for the interests of science and of this in- 

 stitution ; and 



Wliereas, The collection of the Academy is comparatively 

 small and incomplete, and must continue to be so, inasmuch 

 as the former incentive to increase it no longer exists, and 

 also since two collections in Ornithology are unnecessary 

 and inexpedient ; 



Therefore, Resolved, That the collection of birds now 

 belonging to the Academy, be merged in the Wilson Col- 

 lection. 



Resolved, That the galleries nOw occupied by the Orni- 

 thological collection of the Academy, with such of the cases 

 as may be required, be appropriated to the use of the joint 

 collection. 



Resolved, That the Zoological Committee be authorized 

 and instructed to carry into effect the foregoing resolutions.
