COPAIBA  AND  OIL  OP  CUBEBS.

all  the  papers  that  I  have  examined,  from  that  of  the  discovery  of 
aconitia  by  Brandes,  about  1821,  to  that  of  Geiger  and  Hesse,  in 
1832,  and  Von  Planta,  1852,  none  give  the  per  centage  strength 
of  aconite  root,  and  hence  I  have  no  data  to  decide  upon  the  nor- 
mal per  centage  of  the  drug.  The  experiments  were  conducted 
with  entire  fairness,  and  as  nearly  parallel  as  is  usual  in  such 
investigations. — Proc.  Amer.  Pliarm.  Assoc.,  1863.

COPAIBA  CAPSULES. 
36  Piatt  Street,  New  York,  Nov.  IM,  1863. 
To  the  Editor  :— 
Dear  Sir : — As  many  inquiries  have  been  made  as  to  the 
proportions  of  Copaiba  and  of  Oil  of  Cubebs  in  the  cap- 
sules of  Balsam  of  Copaiba  and  oil  of  Cubebs,  as  pre- 
pared by  me,  I  wish  you  would  be  so  kind  as  to  publish  the 
subjoined  formula  in  your  valuable  paper,  so  as  the  profession 
and  trade  will  know  what  they  are. 
I  take  of 
Pure  Balsam  Copaiba,  nine  troyounces, 
Ess,  Oil  of  Cubebs,       one    "  " 
To  be  divided  into  480  capsules,  each  capsule  containing  gr. 
ix.  of  Balsam,  and  gr.  i.  of  Ess.  Oil  of  Cubebs. 
The  capsules  are  made  of  sweetened  gelatin,  after  the  fol- 
lowing proportions ; 
Refined  Gelatin,  95  per  cent., 
White  Sugar,        5  « 
Water,  S,  Q. 
The  "modus  operandi  "  for  making  these  capsules  is  known 
to  every  druggist,  as  described  in  the  U.  S.  Dispensatory,  and 
other  formularies,  by  dipping  metallic  oval  rods  in  the  dissolved 
gelatin,  and  allowing  it  to  cool  on  the  rods,  when  they  are 
taken  off  and  filled  with  a  blow-pipe.
