The  Ligroin  Extract. — Three  hundred  grams  were  dissolved 
in  ether  and  shaken  with  solutions  of  potassium  hydroxide  (5  per 
cent,  and  10  per  cent.).  The  alkaline  extractions  were  acidified 
and  extracted  with  ether.  This  ethereal  solution  was  successfully 
extracted  with  a  solution  of  ammonium  carbonate  (10  per  cent.)  but 
these  extracts  yielded  nothing  but  a  small  quantity  of  smeary  ma- 
terial precipitable  with  acid. 
The  ethereal  solution- was  now  extracted  with  solutions  of  potas- 
sium carbonate,  and  the  fatty  acids  occurring  free  in  the  plant  were 
removed.  The  alkaline  extract  containing  the  potassium  salts  of 
these  fatty  acids  was  acidified  and  extracted  with  ether.  The 
ethereal  solution  of  fatty  acids  was  dried  over  anhydrous  sodium 
sulfate.  The  ether  was  removed  and  a  residue  of  about  92  g.  ob- 
tained. This  was  distilled  under  diminished  pressure.  The  boil- 
ing point  was  215-2500  at  20  mm.,  and  the  iodine  number  of  the 
distilled  acids  which  solidified  in  the  receiving  tube  was  found  to 
be  88.7.  A  very  considerable  quantity  of  this  material  could  not 
be  distilled  and  it  remained  as  a  tar  in  the  flask.  These  fatty  acids 
were  studied  in  connection  with  those  obtained  upon  the  subsequent 
hydrolysis  of  the  glycerides. 
The  ether  solution  which  had  been  extracted  with  ammonium 
carbonate  and  potassium  carbonate  was  now  extracted  with  a  solu- 
tion of  potassium  hydroxide.  The  alkaline  extract  was  acidified 
and  a  quantity  of  tarry  material  (15  g.)  precipitated.  This  was 
dissolved  in  alcohol  and  subjected  to  acid  and  alkaline  hydrolysis, 
but  nothing  crystalline  could  be  separated  in  either  case. 
The  ether  solution  which  had  been  extracted  with  solutions  of 
ammonium  carbonate,  potassium  carbonate  and  potassium  hydroxide 
contained  17  g.  of  neutral  material  belonging  to  the  unsaponifiable 
.material.  It  boiled  at  120-2500  at  15  Mm.,  and  yielded  oily  distil- 
lates exactly  corresponding  to  those  described  among  the  unsaponi- 
fiable products  of  the  fat. 
The  original  ethereal  solution  of  the  fat  which  had  been  ex- 
tracted with  solutions  of  potassium  hydroxide  was  evaporated  to
