Conway MacMillan presented " Notes on the Physiology and 

 Morphology of the Carrion-Plant — Ithijphallus impiidicus (L.) 

 Fries. 



Specimens of this plant were secured at Big island, Lake Minnetonka. 

 It is a fungus which gives off an odor approaching that of decayed flesh, 

 thus deluding flies into making it a receptacle for their eggs. While ovi- 

 positing the flies become covered with spores from the fungus, and the 

 plant thus secures propagation. The special morphological and remarkable 

 developmental adaptations to attain the end of sure and speedy scattering 

 of the spores were noted in detail. 



C. W. Hall gave an account of a geological trip recently made 

 by him through the Wisconsin river valley from Rhinelander to
