110 REPORT OF NATIONAL MUSEUM, 1923. 



Still worked hard to provide an adequate osteopathic exhibit in the 

 history of medicine section of this division, contributing material 

 and enlisting the interest of others in the work. 



Mr. John E. Swanton, of the Bureau of American Ethnology, 

 donated two medical manuscripts written by James Parker, Hart- 

 ford, Conn., in the year 1790. 



The United States Pharmacopoeial Convention (Inc.), through 

 Dr. Murray Gait Motter, Washington, D. C, added to its deposit 

 of historical papers and documents relating to revisions of the phar- 

 macoi^oeia of this country, the Eecord of the Proceedings of the 

 Convention of 1910. 



No explorations nor field trips of any importance were made by 

 members of this division during the year. As a part of the coop- 

 eration of the American Rubber Association in arranging for an 

 exhibit illustrating all the important lines of the rubber industry, 

 the curator was invited to visit nine large plants manufacturing 

 rubber products and was given opportunity to study the various 

 processes therein used. These plants were located in Akron, Ohio, 

 Cambridge, Watertown, and East Hampton, Mass., and Naugatuck, 

 Conn. As a result of the unusual privileges accorded him, the 

 curator was enabled to study in detail the manufacture of automobile 

 tires, hose, belting, and mechanical rubber goods, molded rubbiM- 

 articles, rubber footwear and clothing, rubber thread cutting for 

 elastic goods, and the reclamation of used rubber. From the data 

 thus obtained, a detailed outline of an extensive exhibit was pre- 

 pared and sent to the American Rubber Association as a guide in 

 assembling such exhibit material as could best be used in the Museum. 



C. C. Anderson, aid in organic chemistry, visited New York 

 City during the International Fur Exposition, a trade exposition 

 held by the Associated Fur Manufacturers (Inc.), during May, 1923, 

 and was given the opportunity to study the dressing, dyeing, and 

 finishing of different kinds of pelts. He arranged with several 

 prominent fur manufacturers for exhibit material for the National 

 Musuem, and was promised their cooperation in developing a com- 

 prehensive exhibit of this important industry. 



WORK OF PKESEEVING AND INSTALLING COLLECTIONS. 



The collections under the care of the curator have been carefully 

 inspected for insects, and all perishable material like wools and 

 foodstuti's has been fumigated several times. This has meant, how- 

 ever, constant vigilance. 



The cataloging of new specimens has been kept up to date, and 

 the installation of new material has been made as soon after its 

 receipt as was possible. A large part of the time of one preparator 

 was given to making gummed-letter case labels for the textile 

 exhibits and for the wood and medical collections.
