finish  the  amount  prescribed  in  the  pharmacopoeia  within  an  hour, 
which,  considering  the  time  occupied  in  filtering,  is  not  longer  than 
many  extemporaneous  prescriptions  require. 
The  following  method  is  therefore  offered  in  place  of  the  present 
one  of  the  U.  S.  P.

then  add  by  degrees  the  water  and  triturate ;  when  well  mixed  add 
the  alcohol  gradually,  afterwards  the  camphor  and  oil  of  rosemary,  rub-

SYRUP  OF  SANTONATE  OF  SODA. 
By  J.  DoNDE. 
A  good  vermifuge  syrup  is  prepared  by  the  following  formula : 
Santonate  of  Soda,  30  grains. 
Distilled  water,  1  ounce, 
Syrup,  18  fluidounces. 
Boil  the  syrup  till  it  is  concentrated  to  32°  Bme.  Remove  from  the 
fire,  let  it  cool  a  few  minutes,  then  add  the  salt  dissolved  in  the  water. 
You  obtain  18  fluidounces  of  a  transparent  syrup,  without  a  bitter 
taste,  of  35°  when  cold.  Each  fluidounce  contains  one  grain  of  san- 
tonine.  I  have  been  preparing  this  syrup,  for  nine  years,  in  the  drug 
store  of  Mr.  Font. 
Santonate  of  Soda. 
Santoninic  Acid,  in  fine  powder,  2  ounces. 
Caustic  Soda  Lye,  pure,  4  fluidounces 
Distilled  Water,  12  fluidounces. 
Put  all  in  a  flask,  and  heat  in  a  sand-bath,  or  over  a  stove,  to  70° 
or  80°,  until  the  solution  of  the  santonine  is  complete,  which  usually 
requires  about  half  an  hour ;  then  remove  from  the  fire,  and  when 
cold  it  is  conveniently  evaporated.  In  cooling,  prismatic  crystals 
with  an  oblique  base  are  obtained,  containing  54  per  ct.  of  santonine.  •
