REPORT OF THE BIOLOGICAL SECTION FOR 

 THE SESSION 1896-KS97. 



The Biological Section has only held two informal meetings 

 during the winter, and have given attention to Botany only. 



What should be a very strong section is at present in a weak 

 state, and should have more attention from the members, not only 

 in the line of Botany but in other branches of Biology. 



Our members have been devoting their time to identifying and 

 catalogueing the specimens collected during the past few seasons. 



A careful comparison of these with the lists of Logie and 

 Buchan, and additions made in this Society's Proceedings of 1889 

 and 1890, shows that we have collected 128 species and varieties 

 not hitherto reported from this locality, a couple of these being 

 new to America, a few new to Canada and several new to Ontario, 

 while three critical forms are withheld, subject to Prof. J- Macoun's 

 further examination and report. 



The local additions are as follows : 

 Thalictrum purpurascens — L.
