Although the iinj^rovetl design for the Hayden Memorial Medal was 

 accepted in 190G. as stated in my last annual report, the engraved 

 dies were not received from the Gorham Company until last April. 

 The medal, the work of John Flanagan, of New York, was then cast 

 by Messrs. Krider & Co., of Philadelphia, and has met with general 

 approval, the portrait and the emblematic reverse being regarded as 

 imi)rovements on the design of the token formerly awarded. The 

 Academy has been forced by a variety of circumstances to defer the 

 actual presentation of the medal to Dr. Wolcott until the first meeting 

 of January, when a reception wdll be tendered the distinguished 

 recipient. 



The President was authorized to appoint representatives to the 

 Centenary Celebration of the Geological Society of London, and to the 

 observance of the two hundredth anniversary of the l)irthday of 

 Linnspus by the New York Academy of Sciences.
