at Portici. He is at present director of the Royal Experi- 

 ment Station for the culture of citrus and other fruits 

 at Acireale. Among his numerous contributions to 

 phytopathology the following merit special mention: 



(1) various papers on the olive knot, a bacterial gall 1 ; 



(2) a book on the diseases of trees 2 ; and his essay on the 

 phytopathology of the Greeks, Romans, and Arabs. 3 



Fridiano Cavara, director of the Royal Botanical 

 Gardens at the University of Naples, has made many 

 contributions since 1888 to Italian phytopathologic 

 literature. According to Smith, 4 Cavara was the first 

 to isolate the crown gall organism and make successful 

 inoculations with it. These investigations were made on 

 the crown gall on grapes and published in 1897. 5 



Augusto Napoleone Berlese is another Italian patho- 

 genetist of this period who deserves mention. His first 

 publication on fungi appeared in 1883 (Lindau and Sydow, 

 Thesaurus, 1 : 135). He is perhaps best known as one 

 of the editors of Rivista di Patologia Vegetale, which 

 began to appear in 1892. He died in 1903.
