late.  This  latter  is  assumed  to  be  a  fair  index  of  the  real  value 
of  each  portion  of  the  percolate.  And  if  it  be  not  a  fair  index, 
the  error  is  on  the  safe  side  for  practical  results,  as  it  always 
should  be  where  accuracy  cannot  be  attained.  The  medicinal 
value  given  in  this  column  is  calculated  upon  the  whole 
amount  of  the  extract  yielded.,  and  the  numbers  therefore 
indicate  also  so  many  twentieths  of  the  total  medicinal 
value.  For  example,  the  first  four  fluidounces  of  percolate  of 
Experiment  I.  contains  six  and  two  hundred  and  ten  one  thou- 
sandths per  cent,  of  extract  that  is  medicinal  and  useful ;  or  six
