No. 191. — North American Geologic Formation Names : bibli- 

 ography, synonymy, and distribution ; by F. B. Weeks. 448 

 pp. — This volume is a valuable addition to the scientific registers 

 of facts grown too bulky for memory. The author does not 

 claim that every name that should appear in such a list is actually 

 needed, but every name reported in a list of some five hundred 

 official and serial publications which are given is mentioned. 

 The author has made the list of special value to investigators by 

 presenting the facts exactly as they were presented by the author 

 of the name ; thus throwing upon the user of the register the 

 decision as to which name is entitled to first consideration as the 

 proper name of any particular formation. When it is stated that 

 the bulletin contains 448 pages, the indispensable nature of such 

 a register, for the avoidance of further duplication of names, is 

 apparent. We are pleased to see also that it is proposed to con- 

 tinue this list in the annual Bibliography and Index of North 

 American Geology, which has become a feature of the Bulletins 

 of the United States Geological Survey. h. s. av.

 sum, but a decided falling ojff in the production of zinc. The
