NEW YORK ACADEMY OF SCIENCES 



(Lyceum of Natural History, 1817-1876) 



(1) The Annals (octavo series), established in 1823, contain the sci- 

 entific contributions and reports of researches, together with the records 

 of meetings of the Academy. The articles which comprise each volume 

 are printed separately, each in its own cover, and are distributed imme- 

 diately upon publication. The price of the separate articles depends upon 

 their length and the number of illustrations, and may be learned upon 

 application to the Librarian of the Academy. 



(2) The Memoirs (quarto series), established in 1895, are issued at 

 irregular intervals. It is intended that each volume shall be devoted to 

 monographs relating to some particular department of Science. Volume I 

 is devoted to Astronomical Memoirs, Volume II to Zoological Memoirs, 

 etc. The price is one dollar per part. 



These publications are sent free to Fellows and Active Members. The 

 Annals are sent to Honorary and Corresponding Members desiring them.
