Medicated  Syrups.

to  make  the  same  emulsion,  using  only  f£ii  water  to  begin  with,  I  have 
found  that,  before  half  finished,  it  became  granulated,  and  required 
additional  water  to  spread  the  gum  sufficiently  so  as  to  combine 
smoothly  with  all  the  particles  of  oil.  I  have  made  emulsions  of  cod 
liver  oil,  copaiba,  castor  oil  and  oil  of  turpentine,  by  this  method,  with 
very  satisfactory  success. 
MEDICATED  SYRUPS. 
By  Isaac  Davis,  Ph.G. 
Abstract  from  an  Inaugural  Essay  presented  to  the  Philadelphia  College  of  Pharmacy. 
The  author  refers  to  some  of  the  disadvantages  of  preparing  syrups 
by  boiling,  and  afterwards  to  Mr.  Orynski's  process  for  preparing  syrups 
without  heat  ("Proceedings  Amer.  Phar.  Assoc. ,"  1871,  p.  451). 
Simple  syrup  was  prepared  by  placing  36  troyounces  of  granulated  sugar 
in  a  conical  glass  percolator  upon  a  perforated  diaphragm  covered  with 
a  piece  of  linen,  and  gradually  pouring  distilled  water  upon  it  until  the 
sugar  was  dissolved  and  the  syrup  measured  44  fluidounces.  The 
result  was  quite  satisfactory  however,  the  application  of  the  same 
process  in  the  preparation  of  other  syrups  was  not  equal  in  its  results  to 
those  obtained  with  the  following  process  : 
Syrupus  scillse,  made  by  the  officinal  process,  becomes  cloudy  and 
separates  a  flocculent  albuminous  matter,  but  a  permanently  clear  and 
transparent  syrup  is  obtained  by  making  a  mixture  of  2  fluidounces  of 
acetic  acid  and  30  of  simple  syrup,  adding  of  this  mixture  sufficient  to 
2  troyounces  of  squill  in  moderately  fine  powder  to  obtain  a  thin  paste, 
and  setting  it  aside  for  four  hours  to  allow  of  the  swelling  of  the  squill  ; 
it  is  then  introduced  into  a  conical  glass  percolator  in  the  neck  of  which 
a  piece  of  wet  sponge  has  been  placed  ;  the  surface  is  covered  with  a 
disc  of  paper  and  the  mixture  poured  upon  it  ;  after  this  has  disappeared 
from  the  surface,  three  fluidounces  of  simple  syrup  are  added,  and  the 
last  portion  of  the  syrup  may  be  displaced  by  water,  gradually  poured 
on,  until  the  percolate  measures  two  pints. 
Syrupus  Pruni  virginianse. — Mix  5  troyounces  of  wild  cherry 
bark  in  moderately  coarse  powder  with  2  fluidounces  of  simple  syrup, 
set  aside  for  24  hours  in  a  close  vessel,  then  transfer  it  to  a  conical 
glass  percolator,  and  gradually  pour  upon  it  30  fluidounces  of  syrup 
and  afterwards  sufficient  water  to  make  the  percolate  measure  32  fluid-
