GEOLOGY AND MINERALOGY 



By William North Rice 



Professor of Geology, Wesleyan University 



HE aim of the Smithsonian Institution, as de- 

 fined in the will of its illustrious founder, is 

 twofold — "The increase and diffusion of 

 knowledge." While its contributions in the 

 department of geology have been less exten- 

 sive than in some other departments of science, they have 

 been by no means unimportant. The Institution has ren- 

 dered valuable service in both the incj'case and the diffusion 

 of the knowledge of the constitution and history of the globe 

 on which we live. 



I. PUBLICATIONS 



Attention turns naturally first to the publications of the In- 

 stitution. These include both original papers and reprints 

 of papers published elsewhere. The original papers on 

 geology and mineralogy may be conveniently classified for 

 present purposes in three divisions: i. Miscellaneous papers; 

 2. Papers immediately relating to the collections in the Na- 

 tional Museum or displayed in the temporary expositions in 

 which the Institution has been represented ; 3. Reports of 

 the progress of particular branches of science.
