Remarks on the alterations produced by the phylloxera on the roots of the 

 vine, J. DuFOUR(C7irore. Agr. ('anion Vaud, In ( 1S97), No. 14, pp. -179-384, Jigs. 4). — The 

 alterations are classified as noduosities or swellings and as tuberosities. The first 

 are more or less curved, sometimes so as to form a U. They are formed by a phylloxera 

 attaching itself near the point of a small root which iu growing curves around it. 

 Several insects attacking the root from the same side accentuate the curve. If the 

 attack is on opposite sides of the root the tendency of the swelling is, as a whole, to 

 remain straight. The tuberosities are formed on the larger roots.
