PROPOSED  ECONOMY  OF  ALCOHOL  IN  PERCOLATION,  ETC.  127 
first  two  pints  over  96  per  cent.;  and  that  the  remainder  is  very 
dearly  obtained  at  the  expense  of  two  pints  of  menstruum.  And, 
finally,  other  percolations  of  these  barks,  in  connection  with 
those  recorded  here,  show  that  slight  variations  in  management 
do  not  materially  interfere  with  the  uniformity  of  the  general 
results. 
Starting  from  these  experiments  with  colchicum  seed  and 
calisaya  bark,  thus  studied  out  in  detail  with  care,  other  drugs 
were  extracted  by  percolation  in  a  similar  way.  These  were 
Nux  Vomica,  Gentian,  Alexandria  Senna,  Short-leaved  Buchu, 
and  Cimicifuga.  The  writer  has  neither  time  nor  opportunity 
for  a  series  of  details  in  connection  with  these  drugs,  such  as 
would  be  interesting  and  might  be  useful,  but  must  be  contented 
with  giving  the  results  of  the  fractional  percolations  in  a  tabu- 
lar form.  This  is  the  less  to  be  regretted  since  any  one  can  draw 
the  deductions  from  the  facts  when  stated.  For  convenience  of 
review,  the  corresponding  results  from  the  tables  of  colchicum 
seed  and  calisaya  bark  are  recapitulated  in  this  general  table  :
