fit 
which accounted for the more rapid growth in the pepper and the 
greater shrinking of the diseased area. However the microscopic 
structures were the same in both and the individual acervuli 
similar. 
Less work was done with the Col/etotrichums of the three 
plants under consideration because of lack of virus and of time 
and opportunity to use it. The Colletotrichum ot the egg-plant 
was easily grown upon the pepper. It also thrived upon the bean, 
producing pod-spots, and in turn the native Pod-spot Fungus 
(Colletotrichum Lindemuthianum S. & M.) was grown upon the 
€gg-plant. This was a direct exchange and carries with it a 
double weight of proof. The Colletotrichum of the bean was 
grown upon the pear, and the one native to the pear flourished
