NOTICE RESPECTING PUBLICATIONS. 



The Proceedings of the Washington Academy of Sciences are issued in 

 dated brochures, paged consecutively for the volume. The parts of the 

 volume are issued quarterly, each number consisting of one or more papers 

 bound separately. 



Contributors to the Proceedings must be members of the Academy, or 

 of one of the Affiliated Societies; provided, however, that in exceptional 

 cases the Board may accept for publication papers contributed by non- 

 members of the Affiliated organizations. 



Manuscript submitted for publication must be in form, as well as in sub- 

 stance, ready for the printer. It must be complete as to text and illustra- 

 tions, must be perfectly legible (preferably typewritten), and must be 

 preceded by a brief table of contents < 



Brief notes or other short communications announcing the results of 

 investigations are solicited. They will be brought out in signatures of i6 

 pages or more, and every effort will be made to secure prompt publication. 



Resident and non-resident members having communications of whatever 

 length which they desire to have published in the Proceedings are invited 

 to send them to the Editor, who will promptly submit them to the Com- 

 mittee on Publication, and, if approved, their publication will be expedited 

 as rapidly as possible. 



Authors' separates shall not differ in any particular from the regular 

 edition. Any desired number may be ordered in advance through the Com- 

 mittee on Publication, at the expense of the author, and at a rate of cost 

 agreed upon by the committee and the printer. Authors may receive, free 

 of cost, thirty copies of their papers.
