remaining on hand. It is hoped they may remain here until 

 disposed of by sale or exchange. The plates damaged by the 

 flood of last year have not yet been reprinted. 



Eleven members have been elected since the last report. Dur- 

 ing the same period the deaths of fourteen members have been 

 announced, five have been dropped for non-payment of dues, and 

 seven resignations have been recorded, making a net loss of 

 fifteen. Twelve correspondents have been added to the roll and 

 the deaths of twelve have been recorded. 



A proposition to revise the By-Laws was referred to the Council, 

 February 21. After careful consideration at one stated and two 

 adjourned meetings an amended code was reported to the Acad- 

 emy. It was adopted after reading, at meetings held April 27, 

 May 2 and 9. The most important changes embodied in the new 

 code are the substitution of Assistant Curatorships, the titles and 

 duties of which are to be defined by the Council, for the Profes- 

 sorships, the repeal of the clause limiting the possible continuous 

 term of the presidency to four years, and providing for the ap- 

 pointment of a Committee on Accounts in addition to the Com- 

 mittee on Finance. Numerous verbal alterations were also made, 

 redundancies removed and related clauses placed in juxtaposition, 

 resulting, it is believed, in a clearer and more explicit code than that 

 which it replaces. 



The thanks of the Academy were voted to Miss Adeline S. 

 Tryon for her generosity in satisfying a mortgage of $5,000 on a

A committee consisting of jNIessrs. Nolan, Montgomery, Sharp, 

 Pilsbry and Fox was appointed at the request of the representative 

 of the committee on the proposed international catalogue of scien- 

 tific literature, to consider the preliminary announcement, and to 

 advise as to the desirability of the provisions and methods em- 

 bodied therein. The committee presented a report March 28, 

 1899, which was adopted and ordered to be forwarded as the 

 action of the Academy. 



The lecture hall and library were used for the annual meeting of 

 the American Ornithologists' Union, the most successful, it is 

 believed, in the history of the society, and for the first autumn 

 ession of the Pennsylvania Library Club.
