PUBLICATIONS 



OF THE 



NEW YORK ACADEMY OF SCIENCES 



[Lyceum of Natural History 1818-1876] 



The publications of the Academy consist of two series, viz. : 



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

 the scientific contributions and reports of researches, together with 

 the records of meetings, exhibitions, etc. 



Publication of the Transactions of the Academy was discon- 

 tinued with the issue of Volume XVI, 1898, and merged in the 

 Annals. A volume of the Annals will in general coincide with the 

 calendar year and will be distributed in parts. The price of the 

 current issues is one dollar per part or three dollars per volume. 

 Authors' reprints are issued as soon as the separate papers are 

 printed, the dates appearing above the title of each paper. 



(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 

 as issued. 



All publications will be sent free to Fellows and Active Members. 

 The Annals will be sent to Honorary and Corresponding Members 

 desiring them. 



Subscriptions and inquiries concerning current and back numbers 

 of any of the publications of the Academy should be addressed to
