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 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 organiza- 

 tions, 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 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 of Natural History have been published in 

 the Bulletin series under the heading Contributions from the United States National Herbar- 

 ium 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 254 of the Bulletin series.
