Several systems of catalog numbers have been employed for instruments in
the collections. The earliest instruments were originally collected by the
Division of Anthropology and were given a six-digit number in the division
catalog (referred to as "Anthropology"). Later objects in the collections
have been given a six-digit National Museum of History and Technology
(NMHT) accession number, which serves for all items obtained from one
source at a given date. Before 1973, the Division of Medical Sciences used
a system of numbering individual items by M numbers (e.g., "M-4151").
Since 1973, individual items have been distinguished by adding decimal
numbers to the accession numbers (e.g., "308730.10"). Objects on loan have
been marked as such and given a six-digit number. Other institutional
abbreviations are as follows: SI = Smithsonian Institution; USNM = the
former United States National Museum; NLM = National Library of Medicine.

Photograph numbers are labeled "BW" for black and white negative and "CS"
for color slide. (Copies of photographs or slides may be purchased through
the Office of Printing and Photographic Services, Smithsonian
Institution, Washington, D.C. 20560.) Abbreviations for dimensions of
objects are as follows: D = diameter; L = length; W = width; H = height.
Instruments within each group are arranged chronologically as accessioned
by the museum.
