A  glance  at  this  analytical  table  shows  the  large  amount  of 
ashes  taken  from  the  soil,  carried  into  the  leaves  and  there  deposited. 
In  Emil  Wolff's  Aschen-Analysen,  I,  p.  73,  the  largest  amount  of 
crude  ash  from  a  solanaceous  plant  is  reported  as  22-84  Per  cent. 
While  exhausting  500  gm.  of  powdered  leaves  with  alcohol,  for  the 
extraction  of  alkaloids,  I  separated  nearly  2  gm.  of  well  defined 
crystals,  which,  after  examination,  proved  to  be  chloride  of  potas- 
sium. The  specimen  before  you  represents  the  greater  part  of  this 
KC1  extracted  from  the  leaves  by  commercial  alcohol. 
The  aqueous  extract  contained  over  50  per  cent,  of  mineral  mat- 
ter and  had  a  strong  acid  reaction,  which  was  not  due  to  a  vege-
