  Dm-ing 
  the 
  summers 
  of 
  1889 
  and 
  1890 
  we 
  made 
  a 
  series 
  

   01 
  experiments, 
  with 
  a 
  view^ 
  of 
  determining, 
  if 
  possible, 
  the 
  

   relationship 
  existing 
  betw^een 
  the 
  so-called 
  Phyllosticta 
  la- 
  

   brusca 
  Thum., 
  wdiich 
  occurs 
  on 
  the 
  leaves 
  of 
  the 
  cultivated 
  

   and 
  wild 
  grapes, 
  the 
  Phyllosticta 
  amfehfsidis

  «&

  oc- 
  

   curring 
  on 
  Ampelopsis 
  quinquefolia 
  and 
  A. 
  Vietchii, 
  and 
  the 
  

   various 
  forms 
  attacking 
  the 
  fruit 
  of 
  the 
  cultivated 
  grape, 
  

   which, 
  as 
  shown 
  by 
  Scribner 
  and 
  Viala', 
  are 
  stages 
  of 
  one 
  

   ""gus, 
  namely 
  Lastadia

  and
