294 THE AMERICAN MONTHLY [Oct 



This seems to be the genesis of the trap, and the Bacillaria 

 were formed after the trap, perhaps in the Eocene age. 



Meeting of the American Microscopical Society. 



COLUMBUS, OHIO. 



This society was formed about twenty years ago by per- 

 sons who had broken up the microscopical section of the 

 American Association for Advancement of Science and 

 then launched a separate organization. It has until this 

 year appointed its meetings in cities contiguous to where 

 the parent society was to meet. All this time, people of 

 wisdom have known that separation was very unwise and 

 have urged the society to go back to affiliation with the 

 A. A. A. S. This year for the first time it has done so. ' 

 It took the complete failure of the meeting last year to 

 bring the Society to its senses,but we congratulate it upon 

 the spirit of wisdom which appointed the meeting at Co- 

 lumbus. From local papers we gather the following ac- 

 count of what took place there. 



Thursday August 17.— A meeting of the executive com- 

 mittee was held in the Park hotel, devoted to preparation 

 of a report to the society, which met in the afternoon in 

 Biological Hall, at the State university. The visitors were 

 welcomed to the city by Dr. W. 0. Thompson, president of 

 the university, and the response was made by President 

 Krauss. Secretary Ward presented the annual report, 

 following which papers were announced to be read and 

 discussed as follows, but only two were presented.
