Erysiphaeea?. Further Cultural Experiments with Biologic 

 Forms of the. By E. 8. Salmon [Ann. Bot. xix. Jan. 1905. pp. 125- 

 118). — In a recent paper the author described a method of culture by 

 means of which the conidia of "biologic forms" of Erysiphe Graminis 

 can be induced to infect leaves of host species which are normally immune 

 to their attacks. In the present paper experiments are described in which
