LIBRARY. 



The Library has been maintained in good order, and has been en- 

 riched during the past year by a most valuable donation from Dr. Braith- 

 waite of a large number of interesting papers on Mosses, bound in twelve 

 volumes. The Society has also received a number of other works, the 

 titles of which have been recorded from time to time in the Journal. 



In response to an appeal. for funds to print a Catalogue of the 

 Library, a large amount of support has been given ; the Catalogue, 

 which has been carefully prepared by Mr. P. E. Radley, and the cost of 

 which was largely defrayed by the generosity of 114 Fellow T s, is now com- 

 pleted and ready for distribution to the subscribers.
