PUBLICATIONS. 



The publications of the Academy at present consist of two 

 series — TJie Annals (octavo) and Tlie Memoirs (quarto). All 

 are distributed to Members and Fellows, and are circulated in 

 exchange for the publications of nearly all the foreign and 

 American Academies and learned Societies. The Annals, which 

 opened in 1824, contain the longer contributions and reports of 

 researches, together with the reports of meetings. The Trans- 

 actions, in which the shorter papers and business reports have 

 hitherto appeared, are now abolished and the matter appears in 

 the Annals. The complete volumes of Annals now coincide 

 with the calender year, and appear with a new typography and 

 arrangement of pages. 



The present edition of the Annals is 1,250. The Memoirs, 

 issued in quarto form, are adapted to papers requiring large 

 plates or tabulations. But one number has thus far been issued. 



LIBRARY. 



The Library numbers over 18,000 titles, and is especially 

 rich in sets of the publications of American and Foreign Societies.
