supposed. The exact geological position of the rocks and faunas 
about Sandusky was also determined. Prof. Osborn spoke of his 
work on the Hemiptera of Ohio and New York, several forms 
having been found which will probably prove new. Prof. 
Schaffner reported nutation in six species of plants not previously 
noted; also work on nodding tips of plants and on Myxomycetes 
of Clay Co., Kansas. Mr .York reported thirty-six species of 
plants as new to the Cedar Point list, Fraxinus biltmoreana
