All classes of j\[embers receive the Journal, which is a jiopular illustrated 

 magazine, primarily issued to keep members in touch with the activities of the 

 Dilnseum as depicted by pen and camera ; also to furnish Members with reliable 

 information of the most recent developments in the field of natural science. It 

 takes the reader into every part of the world with great explorers; it contains 

 authoritative and popular articles by men who are actually doing the work of ex- 

 ploration and research, and articles of current interest by men who are distin- 

 guished among scientists of the day. It takes the reader behind the scenes in the 

 Museum to see sculptors and preparators modeling some jungle beast or creating 

 a panorama of animal life. It shows how the results of these discoveries and 

 labors are presented to the million public school children through the Museum 

 Extension System. In brief it is a medium for the dissemination of the idea to 

 which the Museum itself is dedicated — namely, that without deepening apprecia- 

 tion of nature, no people can attain to the highest grades of knowledge and worth. 



In addition to the Journal, publications in the way of Handbooks and Leaflets 

 are issued from time to time in which various subjects embraced in the work of 

 the Museum are treated in a nontechnical way. 



The following list gives some of the popular publications ; complete lists, of both 

 scientific and popular publications, may be obtained from the Librarian.
