OF THE 



CW YORK ACADEMY OF S0IE:^0ES. 



VOLUME IV., 1886 + . 



ne " Annals," published for over half a century by the Lyceum of 



>> >: iral History, are continued under the above name by the New York 



Ac. demy of Sciences, beginning in 1877. Three volumes of the new 



^ ' • s have now been issued, each covering three years (1877-9, 1880-2, 



-5 inclusive). 



ith the beginning of the present volume, the Academy has decided 

 io iiange somewhat the mode of publication. The Annals will hence- 

 forl 1 be issued without particular reference to times or periods. The 

 ■pans will appear as material for them shall be offered; each single part, 

 or umber, as before, will contain at least 32 pages, with or without 

 p)8!3s; twelve numbers, as before, whenever published, will constitute 

 a ^ lurae. The size and general character of the parts and volumes will 

 tr be changed; nor is it intended at all to reduce the average yearly 

 unt of matter. 



le Annals will include the more extended and elaborate papers read 



t.er re the Academy. They will maintain the high standard which has 



n^a e them, for many years past, one of the prominent scientific publi- 



)ns of the world, and has carried the name of the society literally into 



y land. The briefer papers and discussions that form part of the 



demy's meetings, will appear in its other publication, the Trans- 



ONS, which it is designed to issue promptly and regularly, so as to 



a record of the current work of each year, — the single numbers ap- 



peci.ing monthly (or double, bi-monthly), and eight single numbers 



for; ling an annual volume. 



B r vote of the Academy, both these publications will be sent free to 

 its Resident and Honorary members. With the recent increase of an- 

 nur^ dues, the Annals, as well as the Transactions, are now to be in- 

 ch' :ed therein, instead of being furnished only by subscription. 

 " • all others, prices will be as follows: 

 Annals, single numbers, . . . . . One Dollar. 

 " double or triple numbers, in proportion. 

 *' per volume (12 numbers), . . . Ten Dollars. 



Transactions, per year, Three Dollars.
