paper  pulp  was  used. — Editor].  Purified  animal  charcoal,  used  with 
the  oil,  also  yields  good  waters. 
Walter  Theron  Baker  has  principally  operated  with  cinnamon  and 
camphor  water,  and  prefers,  particularly  for  the  latter,  well-burned 
granulated  wood  charcoal  ;  the  kind  used  having  been  obtained  from 
Jersey  pine,  giss  of  the  charcoal  to  3i  camphor  was  found  to  be 
sufficient. 
Preservation  of  Syrups. — Allen  Spengler  has  found  that  a  little 
salicylic  acid  [how  much  ?]  added  to  syrupus  scillae  comp.  would  pre- 
serve it  for  months,  while  portions  of  the  same  syrup,  kept  under  the 
same  conditions,  except  that  no  salicylic  acid  had  been  added,  were 
completely  spoiled. 
Syrup  of  Ipecacuanha. — In  preparing  this  syrup  Wm.  H.  Righter, 
Jr.,  aims  first  at  obtaining  a  fluid  extract  which  will  mix  with  syrup 
without  producing  a  precipitate,  which  is  effected  by  diluting  the 
officinal  fluid  extract  with  water,  filtering  and  evaporating  to  the  proper 
measure.  By  adding  one  fluidounce  of  this  purified  fluid  extract  to 
three  fluidounces  of  syrup  of  tolu  and  then  twelve  fluidounces  of 
simple  syrup,  an  efficient  syrup  of  ipecac  is  obtained,  which  has  a 
pleasant  flavor  and  is  not  prone  to  fermentation. 
Syrup  of  Wild  Cherry  Bark,  possessing  a  deep  brown-red  color 
and  a  strong  odor  of  hydrocyanic  acid,  is  obtained,  according  to  John 
Ritter,  by  first  moistening  the  five  troyounces  of  powdered  wild  cherry 
bark  with  a  mixture  of  two  fluidounces  of  glycerin  and  one-half  a  fluid- 
ounce  of  distilled  water,  allowing  it  to  stand  in  a  closed  vessel  for 
24  hours  and  then  proceeding  according  to  the  directions  of  the  "  Phar- 
macopoeia." 
Variation  in  Fluid  Extracts. — Clayton  K.  Smith  has  made  some 
comparative  experiments  in  relation  to  fluid  extracts,  by  evaporating 
four  ounces  with  a  gentle  heat  to  a  pilular  consistence,  and  weighing 
this  residue.  Whether,  and  in  what  manner  the  amount  of  glycerin 
or  sugar  was  determined,  is  not  stated.  The  results  cannot  be  claimed 
as  possessing  any  analytical  value,  but  they  illustrate  very  forcibly  the 
variation  of  commercial  fluid  extracts.  Nos.  1,  2  and  3  in  the  follow- 
ing table  were  from  three  manufacturers  in  New  York  ;  Nos.  4,  5 
and  6,  from  three  Philadelphia  houses.  The  extracts  yielded  by  four 
[fluid  ?]  ounces  weighed  as  follows  :
