Report of the President 25 



our publication through the new resources of the Jesup Endow- 

 ment. The immediate return from our publications is through 

 exchange with upwards of 400 institutions in this country and 

 abroad, resulting in the continuous enrichment of the Museum 

 library and the constant addition to it of the latest researches 

 cognate to our own in all parts of the world. The second 

 return from publication, while less immediately evident, is 

 still more important. The results of the work of members of 

 our scientific staff are shown in numerous illustrations and 

 figures. Photographic plates brought back from the field are 

 copied or reproduced not only in all our American newspapers 

 and magazines, but in scientific text-books in all languages. 

 Thus in South America, England, France, Germany, Austria, 

 Russia and Japan, one may find the text-books of recent 

 years, especially on the subjects of zoology and vertebrate 

 palaeontology, drawing on illustrations from American 

 Museum sources. British and French periodicals frequently 

 reproduce our work. The modern Handworterbuch der Natur- 

 wissenschaften, the latest encyclopedia of natural science, 

 derives nearly half its illustrations in palaeontology from 

 American Museum sources. Our technical scientific illustra- 

 tions also are freely distributed to makers of school, college 

 and university text-books, as well as to serious scientific organ- 

 izations such as the United States Geological Survey. The 

 four handbooks of the geology of western North America, pub- 

 lished by the Survey in connection with the Panama-Pacific 

 Exposition, have spread our illustrations to thousands of trav- 

 elers all over our western highways. Thus we are not only 

 concerned with the discovery of truth but of its dissemination 

 as widely as possible. Of the 32,000 negatives in our Depart- 

 ment of Public Education, the right of reproduction is extended 

 to all authors, with the proviso that due credit shall be given 

 to the American Museum therefor.
