Publications of the United States National Museum 



The 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 the Museum and setting forth newly acquired facts 

 in the fields of Anthropology, Biology, Geology, History, and Technology. Copies 

 of each publication are distributed to libraries 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. These are gathered in volumes, octavo in size, with 

 the publication 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 Museimi have been 

 published in the Bulletin series under the heading Contributions from the 

 United States National Herbarium. 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 number 237, parts 1-3, of the Bulletin series.
