Take  of  Senna  in  fine  powder,     8  troyounces. 
Coriander  "  4 
Purging  cassia,  bruised,  16  " 
Tamarind,  10  " 
Prune,  deprived  of  seed,   7  " 
Fig,  12 
Sugar,  50  " 
Water  a  sufficient  quantity. 
Digest  tke  purging  cassia  and  tamarind  with  two  pints  of 
water,  and  separate  the  pulp  by  means  of  a  coarse  sieve.  Digest 
the  residue  with  a  pint  of  water  and  separate  the  pulp  and  add 
to  the  first  portion  ;  in  this  pulp  digest  the  prune  and  fig,  pre- 
viously chopped  or  cut  in  fine  pieces,  (a  sausage  machine  serves 
an  excellent  purpose),  and  then  pass  the  pulp  through  a  coarse 
sieve  and  then  through  a  fine  one  ;  in  this  pulp  dissolve  the  sugar 
by  the  heat  of  a  water  bath  and  then  add  the  senna  and  corian- 
der, and  thoroughly  mix  the  whole,  and  evaporate  if  necessary 
by  a  water  bath  until  the  finished  product  weighs  ninety-six 
troyounces. 
It  will  be  seen  that  no  change  is  made  in  the  medicinal  activity 
of  the  preparation,  the  quantity  of  sugar  being  increased  and 
the  quantity  of  water  decreased.  The  writer  in  following  the 
officinal  formula  on  the  large  scale,  found  that  the  preparation 
would  keep  very  well  through  the  winter,  but  would  ferment  in 
hot  weat&er. 
These  suggestions  are  offered  as  a  slight  contribution  to  the 
revision  of  the  Pharmacopoeia,  in  1870.  A  somewhat  careful 
examination  of  the  market,  leads  the  writer  to  conclude  that 
very  much  of  the  confection  of  senna  offered  for  sale  is  not 
made  in  any  degree  in  conformation  with  the  officinal  formula.

In  consequence  of  the  many  controversies  that  have  recently 
taken  place  between  certain  European  chemists,  all,  apparently,
