REPORT OF NATIONAL MUSEUM, 1921. 111 
RESEARCH AND STUDIES CARRIED ON AT THR MUSBUM. 
For the benefit of the Museum.—As much time as could be spared 
from routine work has been given by the curator and one assistant 
to the preparation of comprehensive technical definitions of textile 
fabrics based upon authentic specimens in the Museum’s collections. 
This has meant the careful examination of all available current tex- 
tile literature, as the technical mill and trade terms used in older 
works of reference are often not in accord with those in current use 
in the United States. Considerable progress has been made toward 
the completion of a fabrics glossary based on actual specimens. 
The use of the Musewm’s collections and facilities by visitors and 
correspondents —Dr. Arno Viehoever and Mr. J. F. Clevenger, of 
the pharmacognosy laboratory of the Bureau of Chemistry, De- 
partment of Agriculture, made frequent use of the study collections 
in the division of medicine for identifying and comparing commer- 
cial drugs submitted to that laboratory under the food and drugs act. 
Dr. H. E. Kalusowski, dean of the college of pharmacy, George 
Washington University, made use of the collections in the study of 
gums and resins. 
Mr. Samuel D. Stevens, North Andover, Mass., made use of the 
collections in a study of the development of hand spinning and 
weaving in colonial times. 
One of the professors of the school of medicine, George Washing- 
ton University, frequently brought his class to the Museum to study 
the exhibits in the section of foods. 
The research director of the trade paper Women’s Wear and his 
assistant spent some time studying and sketching the models of 
spinning and knitting machinery in the division of textiles for use in 
the investigation of the history of the knitting industry. 
Numerous visitors made inquiry at the curator’s office in search of 
special information suggested by the exhibits, and made particular 
use of the technical books in the sectional library. The curator 
furnished special information on industrial raw materials and the 
identification of specimens, from time to time during the year to the 
Bureaus of Chemistry and Plant Industry, United States Department 
of Agriculture, and to the New York appraiser’s office, Treasury 
Department. The identification of specimens of fibers and fabrics, 
gums, resins, seeds, and woods, and bibliographical compilations on 
various subjects for numerous individuals, both in and out of the 
Government service, has been a regular part of the work of this 
division. He furnished the identification of the cottons and cotton 
seeds introduced by the Office of Foreign Seed and Plant Introduc- 
tion and Distribution, Department of Agriculture.
