NEW PUBLICATIONS. 



Bibliography of the Geology of Missouri. By F. A. 

 Sampson. Published by the Geological Survey of INIissouri. Mr. 

 Sampson has given to the compilation of this bibliography the labor 

 of several years. The result, an 8vo. of 178 pages, leaves little to 

 be desired, and will be found indispensable to the student of the 

 geology or paleontology of Missouri. Under each title, a brief 

 resume of the contents, or list of species described in each publica- 

 tion, is given. The amount of investigation and labor required for 

 the production of such a volume can be appreciated only by those 

 who have attempted similar projects. Mr. Sampson is to be con- 

 gratulated upon the completion of his work — H. A. P.
