'I'he deposits by Dr. Wilson in 1847 were remarkable for their numbei and 

 value. In their selection also, andiin their adaptation to the wants of the Society, 

 which it has always been his chief desire and pleasure to consult, the excellent 

 judgment characteristic of that gentleman was abundantly shown. The obliga- 

 tions then incurred were sufficiently great, but the statement just presented, 

 exhibits a total of additions derived from him this year nearly double that of the 

 last. 



The entire number of volumes, periodicals and serials in parts or numbers, and 

 pamphlets, which Dr. Wilson has deposited to the present date, is as follows ; 



Volumes, Folios 96, Quartos 212, Octs. 293, Duod. 57, total 858

To our fellow member. Dr. Robert E. Griffith, belongs the credit of being the 

 next largest contributor to the Library during the present year, as he was also 

 in 1847. Nearly 250 works have been added by Dr. Griffith within the last two 

 years ; many of them highly valuable for their antiquity and rarity. 



Among the contributions this year, is a fine copy of Vyse's celebrated and 

 splendid work on the Pyramids of Egypt, in elephant folio, for which the Society 

 is indebted to Dr. Samuel George Morton. To the same gentleman, it is also 

 under great obligations for a donation of the first five volumes of the Asiatic 

 Researches. The Academy's series of that important and frequently consulted 

 work is now nearly complete, one volume only being wanting. The Academy 

 had also the singular good fortune to obtain, at the same period, another set of 

 the same volumes, from its venerable President Mr. William Hembel. 



Through the liberality of the late Mrs. Elizabeth Stott, of Philadelphia, the 

 Library has been enriched the present year by the addition of Wallich's elegant 

 work, PlantfE Asiaticte Rariores, in three large folio volumes. 



To the different scientific Societies, American and foreign, with which the 

 Academy is in correspondence, its acknowledgements are due for their usual 

 courtesy and attention, in furnishing their transactions and other publications ; 

 especially to the Zoological and Linnean Societies of London, the British Asso- 

 ciation, the Geneva Society, the Asiatic Society of Bengal, the Royal Agricul- 

 tural Society of Lyons, the Royal Bavarian Society, the Imperial Society of Natu- 

 ralists of Moscow, the Imperial Mineralogical Society of St. Petersburg, the 

 American Philosophical Society, the New York Lyceum, the Boston Society of 

 Natural History, and the American Academy. 



From numerous distinguished correspondents, authors, &c,, and from editors 

 of scientific journals, at home and abroad, the Academy continues to receive their 

 valuable publications, regarding them as evidences of the general interest ftlt in 

 its success, and of their desire to promote its objects and usefulness. 



The rapid accumulations from all these sources during the last few years, 

 have now nearly occupied the available space in the present apartment, which, at 

 the time of the removal of the Library into it from the Hall, less than two years 

 ago, was considered ample enough for any ordinary rate of increase for a consid- 

 erable period. If, therefore, the Society should be so fortunate as to continue to
