THE MASSACHUSETTS INSTITUTE OF TECHNOLOGY 

 GEOLOGICAL JOURNAL CLUB. 



The club during the last month has devoted 

 much of its time to the reviewing of standard 

 papers on ore deposits, for the benefit of stu- 

 dents interested in economic geology. These 

 articles were reviewed by L. T. Buell, C. H. 

 Clapp, M. Eubel, G. G. Wald, A. H. Allen, 

 W. G. Ball and B. L. Johnson. The other 

 articles reviewed were: 



B. L. Johnson, ' Native Gold Original in 

 Some Metamorphic Gneisses ' (Eng. and Min. 

 Jour., February 4, 1904) ; S. Shapira, ' Mining 

 in Korea ' (Eng. and Min. Jour., March 3, 

 1904) ; W. L. Whittemore, ' Origin, Properties 

 and Uses of Shale' (The Michigan Miner, 

 November, 1899, to February, 1900); J. G. 

 Barry, ' Controlling Sand Dunes in the United 

 States and Europe ' (Jour, of Geog., March, 

 1904); E. Burton, 'The Glacial Geology of 

 Tasmania' (Quart. Jour, of the Geol. Soc, 

 February, 1904) ; H. W. Shimer, ' Evolution of 

 the Mosasaurs ' (Jour. Geol., February, 1904) ; 

 C. E. Danforth, ' The American Mining En- 

 gineer' (Eng. and Min. Jour., February 25, 

 1904). 



Dr. D. W. Johnson spoke on ' A Problem 

 in Eiver-Capture.' His paper dealt with the 

 present and former courses of the Tennessee 

 Eiver, and showed evidence for and against 

 the present theory of its capture as proposed 

 by Hayes and Campbell. Dr. Johnson is now 

 in the field, making further investigation in 

 this problem. G. F. Loughlin,

THE OHIO STATE ACADEMY OP SCIENCE. 



The thirteenth annual meeting was held at 

 Denison University, Granville, November 27, 

 with about thirty members in attendance. 



In the course of the year the academy has 

 published, in addition to its * Annual Eeport,' 

 three ' Special Papers ' : No. 5, ' Tabanidse of 

 Ohio, with a Catalogue and Bibliography of 

 the Species from America North of Mexico,' 

 63 pages, by James S. Hine; No. 6, 'The 

 Birds of Ohio, A Eevised Catalogue,' with 

 copious notes, 241 pages, by Lynds Jones ; No. 

 7, 'Ecological Study of Big Spring Prairie,' 

 96 pages, by Thomas A. Bonser. The studies 



upon which these papers were based were 

 largely carried on by aid from the Emerson 

 McMillin Eesearch Fund, and the expense of 

 publication was mainly met by the further 

 aid of the same fund. The series of special 

 papers and the annual reports will be con- 

 tinued, but hereafter the Ohio Naturalist will 

 be the official organ of the academy and in it 

 will be published the abstracts and papers of 

 less than 1,500 words. 



The officers chosen for the ensuing year are : 



President — E. L. Moseley. 



Vice-Presidents — Lynds Jones and L. H. Mc- 

 Faddeu. 



Secretary — F. L. Landaere. 



Treasurer — Herbert Osborn. 



Members of the Executive Committee — W. E. 

 Wells and W. F. Mercer. 



Member of Publication Committee — James S. 

 Hine. 



Trustee — W. R. Lazenby. 



Librarian — W. C. Mills. 



Correspondence regarding publications may 

 be addressed to W. C. Mills, Page Hall, Ohio 

 State University, Columbus, O. 



The address of the president, C. J. Herrick,
