tion that,  contrary  to  what  had  been  told  him  at  the  time  of  his  accepting 
the  subject,  he  was  unable  to  find  the  growing  plant  in  any  of  the  gardens,

publication.

ferred for  publication.

culture  of  Arnica  in  this  country,  reported  verbally,  through  Dr.  Guthrie,

sired that  the  subject  be  continued  to  him  till  next  year,  which  was  granted .
