2 14 ROCHESTER ACADEMY OF SCIENCE. [Mar. 24, 



wrote me as follows : "In regard to Rhizopus nigricans on grape, I 

 have to say that it is very common not only on grapes which have 

 been kept too moist and have thus started to decay, but also upon all 

 other kinds of fruit. It is not strictly a parasite and I doubt whether 

 it can be considered as at all parasitic, although after it starts on a 

 bruised or broken berry it hastens decay. The only way to prevent it 

 is to keep the berries dry and remove all broken berries.
