Publications of the United States National Museum 



The scholarly and scientific publications of the United States National Museum 

 include two series, Proceedings of the United States National Museum and United States 

 National Museum Bulletin. 



In these series, the Museum publishes original articles and monographs dealing 

 with the collections and the work of its constituent museums — the Museum of 

 Natural History and the Museum of History and Technology — setting forth 

 newly acquired facts in the fields of anthropology, biology, history, geology, and 

 technology. Copies of each publication are distributed to libraries, to cultural and 

 scientific organizations, and to specialists and others interested in the different 

 subjects. 



The Proceedings, begun in 1878, are intended for the publication, in separate form, 

 of shorter papers from the Museum of National History. These are gathered in 

 volumes, octavo in size, with the publication date of each paper recorded in the 

 table of contents of the volume. 



In the Bulletin series, the first of which was issued in 1875, appear longer, separate 

 publications consisting of monographs (occasionally in several parts) and volumes 

 in which are collected works on related subjects. Bulletins are either octavo or quarto 

 in size, depending on the needs of the presentation. Since 1902 papers relating to 

 the botanical collections of the Museum of Natural History have been published 

 in the Bulletin series under the heading Contributions from the United States National 

 Herbarium, and since 1959, in Bulletins titled "Contributions from the Museum of 

 History and Technology," have been gathered shorter papers relating to the 

 collections and research of that Museum. 



This work forms volume 274 of the Bulletin series.
