are both members of the Washington branch of the association, the 

 former being Vice-President, they made every effort to acquaint the 

 pharmacists with what the National Museum is doing- in this direc- 

 tion. Other exhibits installed in the division of medicine during 

 the year comprised the following: 



Two cases devoted to medicines obtained from inorganic mate- 

 rials; two to the subject of essential oils; one showing types of 

 pharmaceutical balances, ancient and modern ; a case showing- 

 sources, preparation and uses of two vegetable drugs, cascara sagrada 

 and mix vomica ; two cases showing preparation and use of vaccines 

 and serums in combating smallpox, diphtheria, and lockjaw: two 

 models illustrating distillation of -essential oils, and a temporary 

 installation of the "Medicinal Forms'* exhibit. 



In the section of wood technology the Moor cases in the court were 

 rearranged and seven new installations were made covering the fol- 

 lowing subjects: Cork, wood pulp and waste wood products, paper 

 yarn and rugs, basket making machine, California redwood, and 

 miscellaneous articles made from wood. 



In the division of textiles nine new installations covering silks, 

 yarns, and knitted fabrics were set up during the year. 



A model of a peppermint still was made in the laboratory of the 

 division, from drawings and photographs supplied by the foremost 

 distiller of peppermint oil, and a 4-harness demonstration loom and 

 appliances for warping the same were constructed under the super- 

 vision of the curator. 



A large part of the time of one preparator was given to the making 

 of gummed-letter labels for the objects in the hospital equipment 

 exhibit, and for the cases in the exhibition halls. 



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

 the entire card catalogue of textiles and fibers have been classified 

 and arranged under subject headings. 



The examination and indexing of new textile terms and other 

 special information contained in the large number of trade papers 

 and periodicals sent to the sectional libraries of textiles, woods, medi- 

 cines, and foods, has occupied the time of the preparators when not 

 engaged in other duties. 



The material accumulated between 1881 and 1911, which was 

 crowded out from exhibition into storage before the occupation of 

 the Natural History Building, is in need of overhauling. Some of 

 the specimens have deteriorated through effects of time and changes 

 in temperature, and should be condemned. All of the. collections 

 under the care of the curator have been carefully inspected for in- 

 sects, and all the materials like wools and foodstuffs have_ been 

 fumigated several times. Several of the large panels of Philippine
