From the above statistics and the accompanying list of addi- 

 tions it will be seen that, apart from exchanges received from 

 societies and editors, the gro-wth of the library has been raainlj- 

 dependent upon the I. Y. Williamson Fmid. 



It gives the Librarian pleasure to be able to report the comple- 

 tion of the card catalogue of all the special departments of the 

 library coming within the province of the Acadeni}'. It is to be 

 hoped that some of the remaining sections, at present arranged 

 on the gallery, may soon be disposed of hy sale or exchange, as 

 the}- embrace books of a character rarely- or never consulted in 

 the Academy ; although many of them would be of importance 

 and Talue elsewhere. The revision of the catalogue of journals 

 and periodicals is progressing slowly, as time is taken after the 

 completion of each geographical section to apply for all deficiencies 

 noted. The answers to such applications thus far made have beeir 

 so satisfiictor}- as to warrant the hope that important additions 

 will be received from this source during the coming year. 



The collection of portraits of the Presidents and benefactors of 

 the Academy has been increased b}^ the addition of a fine oil 

 painting of Isaac Lea, LL. D., by Ulile, one of Dr. Isaac Hays, 

 b}- Waugh and a life-sized crayon portrait of Mr. Isaiah V. Wil- 

 liamson. For these gifts, interesting not onh' as works of art, 

 but also as memoi'ials of men to whom the society is indebted for 

 many and permanent benefits, the thanks of the Academy 

 are due to Dl". Lea, Mrs. Dr. Isaac Hays and Mr. Williamson. 

 The Acadeni}^ now possesses the portraits of eight out of its ten 

 presidents, those of Dr. Thos. B, Wilson and Dr. Robert Bridges 

 being j-et lacking. It is to be hoped that these ma}' be supplied, 

 and that the series, which will certainl}' be of great interest here- 

 after, may be kept complete. 



Fine framed photographs of Dr. Jos. Leid}^ and the late Prof. 

 Henr}^ have been received from Mr. F, Gutekunst,and Dr. C. W. 

 De Lannoy has presented a death mask of Di*. James Aitken 

 Meigs.
