None  of  the  experiments  produced  with  the  official  amount  of  alco- 
hol, an  extract  to  represent  the  powder,  operated  upon.  To  arrive  at 
any  certainty,  many  times  this  number  of  disinterested  investigations 
must  be  put  upon  the  official  fluid  extracts.  The  result  of  the  line 
I  offer,  unmistakably  favors  simple  percolation  without  maceration;  but 
fluid  extract  of  cimicifuga  may  possibly  be  exceptional,  and  it  would 
not  be  well  for  those  who  have  not  experimented  farther  to  prepossess 
themselves  in  favor  of  any  theory  from  the  summing  up  of  the  few 
experiments  I  offer  in  this  paper.  Of  primary  importance,  to  pharma- 
cists, is  the  question,  "can  we  practically  produce  a  liquid  extract 
each  fluidounce  of  which  will  contain  the  medicinal  principles  of  one 
troyounce  of  crude  material,  on  operating  with  such  quantities  as  the 
U.  S.  P.  directs  ?"   
ON  A  DISTILLATORY  APPARATUS. 
By  Joseph  P.  Remington. 
Having  occasion  to  use  frequently  the  ordinary  forms  of  pharmaceu- 
tical stills,  for  recovering  alcohol,  in  making  fluid  extracts,  and  for 
other  purposes,  and  noticing  some  defective  points  in  their  practical 
operation,  the  writer  finally  contrived  the  apparatus  which  is  figured 
in  the  cut,  and  a  continuous  use  of  over  three  years,  having  proved 
its  efficiency,  it  is  herewith  submitted. 
The  greatest  objections  to  the  pharmaceutical  stills,  usually  sold  by 
the  makers,  are  the  use  of  the  water  joint,  and  the  short  distance 
remaining  between  the  delivery-pipe  and  the  source  of  heat  when  the 
still  is  in  position.  The  water-joint  is  always  objectionable  ;  when  the 
still  is  in  use,  constant  care  and  attention  is  required  to  keep  it  full  of
