NATURAL SCIENCES OF PHILADELPHIA. 429 



The catnlogiics of the works on Geology, Eutoinology, and 

 General Natural History have been carefully revised, and the en- 

 tries in the first named, numbering 1902 titles exclusive of cross- 

 references, have been arranged in alphabetical order, read}^ for 

 transcribing. 5.'^8 Geological pam])hlets have been indexed and 

 bound in 31 volumes; and 1(U pamphlets on General Natural 

 History haA-e been arranged in 12 volumes. 



In the department of Journals and Periodicals the cases and 

 shelves have been numbered, and the position of each work indi- 

 cated on a new catalogue, which has been completed and is here- 

 with presented. The numbers are merel3' provisional, as the 

 amount of shelf room in tiiis, section of the librarj'^ is entirely too 

 small to permit of a proper display of the volumes. Whilst the 

 old arrangement in this department has not been altered, it is yet 

 hoped that the reference to the case and shelf will facilitate the 

 finding of Journals, which, in the mere geograpliical classification, 

 might readil}' be overlooked. The entries in this catalogue number 

 tG3. 



The library has been kept open in the evenings until 10 o'clock 

 since the 2d of last April. The attendance of members has been 

 small, but the additional time at the disposal of the librarian has 

 given him an opportunity of finishing much of the work above 

 reported, the greater part of which would be still incomplete had 

 his attendance ]:)een confined to the morning hours, as formerlj-. 

 All of which is respectfully submitted, 



Edward J. Nolan, Librarian. 



REPORT OF THE CURATORS. 



But little change has been made in the Museum of the Academy 

 towards the arrangement in o;eneral of its collections since the 

 presentation of the last annual report. Under the voluntary and 

 assiduous labor of the committee of arrangement of the Concho- 

 logical Section, the conchological cabinet has been completely 

 arranged and labelled, and may now be regarded as in better con- 

 dition than any other collection of the Museum. For a special 

 account of that cabinet, and the additions made to it during the 

 year, we refer to the Report of the Conservator of the Concho- 

 logical Section. 



The Curators regret to state that several of the collections of
