The  European  or  prickly  gooseberry,  owing  to  the  mildew  to 
which  it  is  subject,  is  not  so  successfully  grown  in  America  as  the 
smooth-berried  varieties  derived  from  native  species.    Some  of  our

Garcin1  describes  the  microscopic  structure  of  the  pericarp  of 
R.  Uva-Crispci  [R.  Grossularia).  Blyth2  devotes  but  a  single  sen-

A  study  was  made  by  the  writer  of  the  berries  of  ''Carmen,"  a 
prickly  variety  grown  in  the  Station  garden  ;  and  also  of  an  unknown 
variety,  unquestionably  R.  Grossularia,  grown  in  Scotland.
