Galenical  Fi^eparations.

sulphate  of  potassium  2  parts;  chloride  of  sodium  18  parts;  bicarbo- 
nate of  sodium  36  parts ;  reduce  to  fine  powder  and  mix. 
A  solution  of  6  grams  of  this  salt  in  1  liter  of  water  is  very  similar 
to  Carlsbad  loater. 
Sapo  jalapiniis. — Dissolve  resin  of  jalap  and  medicated  soap,  of  each 
4  parts  in  alcohol  (sp.  gr.  894)  8  parts,  and  evaporate  in  a  steam  bath, 
with  continual  agitation,  until  the  mass  weighs  9  parts.  It  is  brown- 
yellow,  soluble  in  alcohol,  and  yields  with  2  or  3  parts  of  water  a 
turbid  solution  ;  with  from  10  to  20  parts  of  water  a  nearly  clear  solu- 
tion is  obtained,  which  does  not  separate  any  resin. 
Sapo  kallnus. — Solution  of  potassa  (sp.gr.  1*144)  135  parts;  linseed 
oil  100  parts;  mix  gradually  in  a  water  bath,  heat  for  half  an  hour, 
stirring  continually,  and  thoroughly  mix  with  alcohol  25  parts ;  add 
gradually  water  200  parts,  and  continue  the  heat  until  a  pellucid  jelly- 
like soap  is  formed,  which  dissolves  in  hot  water  without  separating 
any  oil ;  then  evaporate  by  means  of  a  steam  bath  until  the  alcohol  has 
been  expelled  and  the  weight  is  reduced  to  150  parts. 
Soft  Soap  thus  prepared,  is  brownish-yellow,  pellucid,  slippery,  of  a 
slight,  but  not  nauseous  odor,  free  from  granules,  and  soluble  in  water 
and  alcohol ;  it  must  always  be  dispensed  unless  sapo  kalinus  venalis 
is  especially  prescribed. 
Sapo  medicatus. — The  saponification  is  effected  in  a  similar  manner 
as  in  the  preceding  case,  solution  of  caustic  soda  (sp.  gr.  1*161)  120 
parts,  being  first  heated  with  a  mixture  of  50  parts  each  of  lard  and 
olive  oil;  then  alcohol  12  parts,  and  water  200  parts  are  added. 
When  the  saponification  has  been  completed,  the  soap  is  separated  by 
the  addition  of  a  solution  of  sodium  chloride  25  parts,  and  sodium 
•carbonate  3  parts,  in  water  30  parts,  strongly  expressed  and  dried.  It 
is  white,  free  from  rancid  odor,  and  soluble  in  water  and  alcohol. 
Saturationes. — Unless  otherwise  indicated,  ^o^io  River i  is  dispensed, 
when  a  saturation  (neutral  mixture)  is  prescribed. 
Species. — The  substances  used  for  these  mixtures,  are  to  be  uniformly 
■comminuted  and  freed  from  the  fine  powder ;  for  the  preparation  of 
infusions  or  decoctions,  they  should  be  passed  through  sieves  with 
meshes  from  4  to  6  millimeters  wide ;  for  pulverulent  species  the 
meshes  should  measure  2  to  3  millimeters. 
Species  aromatica^.  —  Peppermint,  garden  thyme,  wild  thyme  and 
lavender  flowers,  of  each  2  parts,  cloves  and  cubeb,  of  each  1  part ; 
mix.
