The trustees of the Research Fund reported a 

 further gift of $250 from Mr. Emerson MeMillin, 

 of New York, for the encouragement of the re- 

 search work of the academy. Since the last meet- 

 ing a grant to L. B. Walton has been paid, and 

 new grants made to L. S. Hopkins, F. L. Landaere, 

 W. H. Shideler, B. W. Wells and Stephen R. Wil- 

 liams. 



Gratifying progress was reported by the com- 

 mittee on scientific journals. The scope of this 

 work, in which the academy is cooperating with 

 the Ohio Library Association, is shown by the fol- 

 lowing paragraphs from the appeal for cooperation 

 mailed to all important libraries in the state: 

 ' ' The Ohio Academy of Science and the College 

 Section of the Ohio Library Association jointly 

 propose to compile a union catalogue of the 

 periodical and scientific sets (except documents) 

 in the libraries of the state. This catalogue is to 

 be made on cards, and filed with the Ohio State 

 University Library, the official depository of the 

 Ohio Academy of Science. Ultimately the acad- 

 emy hopes to print this union catalogue for the 



benefit both of librarians and of scientists. How- 

 ever, until printed, it will be possible for any one 

 to write directly to the Ohio State University Li- 

 brary and secure information concerning the loca- 

 tion of any scientific set in the state." 



' ' The Ohio Academy of Science has been work- 

 ing on such a proposition for several years, and 

 much of preliminary data has been received. At 

 the October, 1915, meeting of the Ohio Library 

 Association a committee was named to compile a 

 union catalogue of periodical sets so that li- 

 brarians might know where sets are when needed 

 by them in the various universities and colleges. ' ' 



' ' Therefore, this joint effort of the two associa- 

 tions, as outlined above, will bring into existence a 

 bibliographical tool, the value of which will be in- 

 dispensable to the college librarians and to the 

 scientists of the Ohio Academy." 



Obituary notices of Professor F. M. Webster, of 

 Washington, D. O, and Professor John Royer, of
