fluidounce,  while  the  fifth  column  gives  the  actual  expense  of  each 
ounce  of  percolate,  estimating  alcohol  to  be  worth  $2.24  per  gallon, 
and  the  7,680  grains  cimicifuga  20  cents. 
The  comparisons  in  these  two  tables  are  based  upon  the  supposition 
that  equal  proportions  of  all  principles  continue  to  be  abstracted  until 
the  powder  is  depleted. 
This  consideration  is  necessary  here,  but  my  previous  statement  will 
be  remembered,  that  my  experiments  do  not  permit  me  to  believe  each 
portion  of  a  percolate  contains  the  same  component  principles,  a  point 
yet  to  be  considered.

Simple  Percolation  without  Maceration. — In  a  percolator  two  and 
forty-five- hundredths  inches  in  diameter,  prepared  like  those  mentioned 
on  page  4,  January  No  ,  7,680  grains  of  powdered  cimicifuga,  previ- 
ously moistened  with  four  fluidounces  of  alcohol,  were  introduced, 
and  pressed  until  it  occupied  fifteen  inches  in  height.  After  covering 
the  powder  with  a  circular  piece  of  paper,  alcohol  was  supplied,  con- 
tinuously, until  twenty-four  fluidounces  of  percolate  were  obtained. 
The  percolate,  as  it  passed,  was  separated  into  portions  of  one  fluid- 
ounce  each.
