than  that  which  grows  wild.  This  statement,  which  is  no  doubt 
true  of  plants  transported  to  a  soil  unsuited  to  them,  has  not  been 
confirmed  by  the  author's  experience,  indeed  on  the  whole  the 
cultivated  plant  has  been  found  to  contain  a  little  more  alkaloid 
than  that  grown  wild.  The  percentage  of  alkaloid  found  in  the 
leaves  and  stem  of  the  dried  wild  plant  was  0.49,  while  the  average 
of  that  found  in  the  cultivated  plant  during  the  eight  years  1906- 
1913  was  0.57.  As  other  investigators  have  usually  recorded  about 
0.45  per  cent,  in  the  wild  plant  it  may  be  assumed  that  the  plant  em- 
ployed was  satisfactory,  it  therefore  follows  that  the  effect  of  cultiva- 
tion has  been  beneficial. 
In  the  following  table  a  number  of  analyses  of  belladonna  stems 
and  leaves,  grown  under  treatment  with  various  fertilizers  on  the 
same  plot  for  four  successive  years  are  given :
