PUBLICATIONS 



OF THE 



NEW YORK ACADEMY OF SCIENCES 



(Lyceum of Natural History, 1817-1876) 



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 rec- 

 ords of meetings and similar matter. 



A volume of the Annals coincides in general with the calendar year 

 and is sold at the uniform price of three dollars per volume. The articles 

 composing the volume are printed separately, each in its own cover, and 

 are distributed in bundles on an average of three per year. The price of 

 the separate articles depends upon their length and the number of illus- 

 trations, and may be learned upon application to the Librarian of ^ the 

 Academy. The author receives his separates as soon as his paper has 

 been printed, the date of issue appearing above the title of each paper. 



(3) 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 are sent free to Fellows and Active Members. The 

 Annals are 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
