 we have expressed, that the mildew fungi only attacks 

 those trees the sap of which is already in a state of 

 incipient disease.

Blotches on the fruit are an induration or harden-

 exposed to sudden transitions of temperature. We 

 never observed these blotches on forced peaches. 



Splitting of the fruit arises from the sudden
