The Smithsouian Institution solicits for the library of the United 

 States National Museum, under its charge, copies of publications re- 

 lating to all departments of anthropology, art, technology, zoology, 

 botany, geology, mineralogy and lithology, geography and explora- 

 tions, the reports and catalogues of societies, museums, and zoological 

 gardens, as well as copies of plans and labels and other accessories of 

 work in museums, aud the catalogues of colleges and schools containing 

 reference to courses of instruction or collections in natural history. 



Authors' editions, or "separates" of communications published in 

 periodicals, or proceedings of societies, are especially desired; and it 

 is hoped that authors will furnish, as far as possible, sets of their pub- 

 lications complete to date. 



The Smithsonian Institution oifers in exchange an equivalent in 

 copies of the proceedings and bulletins of the National Museum, a 

 catalogue of which, complete to date, accompanies this circular; also 

 such of its reports and other publications as can be supplied at the 

 time of application. 



The Smithsonian Institution is pleased to receive from investigators 

 in special departments, and from public museums and institutions of 

 learning, applications for such specimens of natural history as are found 

 in North America.
