Distribution of duplicate specimens. — Duplicate specimens, tothenum- 

 oer of 11 ,383, were distributed during the year among museums, colleges, 

 and individuals. The following table shows the character and extent of 

 these distributions :

The decrease in the number of specimens thus given away, as com- 

 pared with last year, is accounted for by the fact that only 2,072 speci- 

 mens of marine invertebrates have been distributed this year, while 

 last year 24,750 specimens of this class were presented to applicants. 

 Eliminating this class of specimens, the number distributed this year is 

 double that of last year. The number of requests for duplicate specimens 

 increase yearly. It is hoped that in the future it may be possible for the 

 Museum to extend its usefulness in tliis important part of the work. 

 The material now available for distributi on is quite inadequate to supply 

 the demand. The curators of mineralogy and of geology obtained a large 

 quantity of material during the past summer for this special purpose. 

 As soon as it has been classified and arranged into sets, an endeavor 

 will be made to fill the many applications for mineralogical and litho- 

 logical material now awaiting action. The matter of making up sets of 

 duplicate bird-skins is now receiving careful attention, there being 

 much of such material available for distribution. 



Labels. — During the year, 3,991 labels were printed, chiefly for use iu 

 the departments of metallurgy, materia medica, and birds,
