three thousand species and more than double that number of speci- 

 mens, there still remains ample room for addition, both through 

 the continued liberality of individuals and from the purchases di- 

 rected by the Trustees ; and when the new arrangement is com- 

 pleted, the collection will, the writer doubts not, be found worthy 

 of the nation and of the establishment of which it forms a part. 



Hampstead, October 1839.
