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 are published original articles and monographs dealing with the 

 collections and 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 various subjects. 



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

 of shorter papers from the Museum of Natural 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 have been published in the 

 Bulletin series under the sub-series Contributions from the United States National 

 Herbarium. Since 1959, in Bulletins titled "Contribiuions from the Museinn of 

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

 and research programs of that museum. 



This work forms ninnber 269 of the Bulletin series.
