fied  with  caustic  potash,  and  the  desired  green  color  is  imparted  to  it 
by  blue,  green  or  yellow  pigments,  as  may  be  required.  Frequently, 
however,  soft  soap  is  met  with  of  a  blackish,  or  rather  such  a  dirty 
color  that  it  is  difficult  to  distinguish  a  particular  tint.  The  soft  soap 
of  the  London  Pharmacopoeia  of  1851,  and  of  the  Edinburg  Phar- 
macopeia of  1841,  was  directed  to  be  made  from  olive  oil  and  potash. 
Green  soap  is  mainly  used  in  medicine  for  the  cure  of  itch,  and  in 
various  other  skin  diseases ;  but,  on  account  of  its  caustic  nature,  is 
not  often  applied. 
The  following  formulas*  have  been  furnished  to  us : 
Lotio  Saponis  viridis  [Prof.  Hebrd).  Green  soap  ^i,  boiling  water 
Oj,  oil  of  lavender  sss.  Mix. 
Spiritus  saponatus  kalinus  {Prof.  Hebra)%  Green  soap  2  parts,  95

Tinct.  Saponis  vir.  comp.  {Tilbury  Fox).  Green  soap,  oil  of  cade,f

EXTRACTUM  IPECACUANHA  FLUIDUM.* 
By  B.  F.  McIntyre. 
The  Pharmacopoeia  of  1860  and  the  revision  recently  published 
give  formulas  for  the  preparation  of  Fluid  Extract  of  Ipecac.  The 
alteration  of  the  old  formula  given  in  the  new  edition,  suggested  the 
following  experiments  to  determine  whether  the  change  is  an  improve- 
ment. 
*  Several  of  these  formulas  may  be  found  in  Napheys'  Modern  Therapeutics.
