Recent experiments in the destruction of phylloxera upon grapevines, 

 G. CouANON ETAL. {Bul.Min. Agr. [France'], 19 (1900), No. l,pp. 135,136).— k number 

 of experiments were tried by the authors in ridding grapevine plants of the phyl- 

 loxera. Plants were immersed in hot water for 5, 4, and 3 minutes for different lots. 

 The water in each case had a temperature of 53° C. at the beginning and 51° at the 

 end of the immersion. The plants were not injured in any case by the immersion in 

 .hot water and the phylloxera were killed in l)oth the adult and egg stages.
