REPORT OF THE BOTANICAL COMMITTEE. 



To the President and Members of the Academy : — 



During the past year the Committee have devoted themselves to 

 distributing the valuable specimens contained in the various col- 

 lections through the general and the North American Herbariums. 

 In our last report it was stated that owing to the cases being 

 full, and not permitting from their structure any additions, these 

 specimens were temporarily arranged in a supplemental herba- 

 rium. By the consent of the curators these old cases will be 

 abandoned, and simple portfolio cases employed in their stead. 

 This has enabled the Committee to distribute the plants in their 

 proper places in the general herbarium. 



At the beginning of last year the index of the general herba- 

 rium contained the names of 3239 genera. By the labors of the 

 Committee 170 new ones have been added. The work during the 

 next month will be entirely finished. 



Thomas Meehan, /or the Committee. 



The Treasurer's Report was read and referred to the Committee 

 on Finance.
