Science, Cliemistiy, Geography and Medicine, together with the 

 Italian journals, added to the card catalogue. The Department 

 of Conchology had not been before included in the card entries, 

 because a complete hand catalogue had been prepared just before 

 the card system was adopted, and a similar arrangement of the 

 other departments mentioned has not heretofore been possible for 

 lack of time. I regret to say that, for the same reason, tlie 

 American and Italian journals only have as yet been completely 

 catalogued, although the hand index to the shelf arrangement, in 

 use for several years back, has been kept roughly up to date, and 

 serves its purpose reasonably well. Eveiy effort will be made 

 during the coming year to complete the catalogue of this 

 department. 



A circular which was sent to all our corresponding societies, 

 proposing an exchange of publications by mail, has been answered 

 favorably by a few societies, but the greater number seem to 

 prefer sending but once a } ear, as heretofore, through the Inter- 

 national Exchange Bureau. This is to be regretted, as early 

 access to the current scientific literature is of the utmost impor- 

 tance to the student. Of course, the many journals for which the 

 Academy subscribes, and which are all credited in the accom- 

 panj'ing list to the I. Y. Williamson Fund, are received promptly 

 by mail as issued. 



It will be observed that we are indebted to the liberality of 

 Mr. Joseph Jeanes for 83 of the current additions, and to the 

 fund which the Academy has received from Mr. Isaiah Y. 

 Williamson for 437 volumes and continuations of periodicals. 

 These additions are of special value and importance, as they have 

 been ordered at the request of the working members, and supply 

 for the most part the material required for actual investigation. 



A fine portrait in oil of Dr. Joseph Leid}^, b}^ Uhle, has been 

 placed on permanent deposit by the Biological Club of Phila- 

 delphia. The amount required for the portrait of Dr. Robert 

 Bridges having been secured, the order was given to Mr. Uhle 

 early in the year. 1 regret to sa^' the artist's engagements have 

 not enabled him to complete the work, which will, however, be 

 placed in the library at an earl^' date. 



All of which is respectfully submitted, 



Edward J. Nolan, 



Librarian.
