dryness  and  the  residue  was  saponified  by  boiling  with  250  Cc.  of  10 
per  cent,  alcoholic  potash  for  about  five  hours.  The  alcohol  was 
removed  and  water  added  to  completely  precipitate  the  unsaponi- 
fiable  material,  which  was  extracted  with  ether. 
Examination  of  the  Unsaponifiable  Matter. — The  dried 
solution  was  evaporated  to  dryness  and  the  residue  was  an  orange- 
colored  oil  amounting  to  47  g.  It  was  dissolved  in  absolute  alcohol 
and  upon  standing  0.15  g.  of  material  separated.  The  melting 
point  was  indefinite  (62-760)  and  suggested,  as  stated  by  Power 
and  Callan,  a  mixture  of  hydrocarbon  and  a  higher  alcohol.  By 
means  of  the  phthalic  acid  fusion,  and  subsequent  extraction  with 
sodium  carbonate,  a  small  quantity  of  a  hydrocarbon  melting  at  61 0 
was  isolated.  Three  crystallizations  from  ethyl  acetate  raised  this 
melting  point  to  63 °.  It  separated  in  colorless  leaflets  and  was 
perliaps  impure  hentriacontane. 
Calc.  for  C3iH64:  C,  85.3;  H.  14.7.    Found:  C,  85.1;  H,  14.1. 
A  small  quantity  of  a  sodium  salt  of  an  acid  phthalic  ester  was 
isolated  and  boiled  with  alcoholic  potash.  A  product  separated 
which  had  the  melting  point  of  myricyl  alcohol,  82-840.  It  crys- 
tallized from  alcohol  in  leaflets,  which  softened  at  82 0  and  melted  at 
85°. 
Calc.  for  C30H62O:  C,  82.2;  H5  14.1.    Found:  C,  81.7;  H,  13.5. 
The  alcoholic  solution  from  which  the  hydrocarbon  and  myricyl 
alcohol  had  separated  yielded  no  further  crystallizations  even  from 
concentrated  solutions  after  the  addition  of  small  quantities  of 
water.    This  residue  was  distilled  under  diminished  pressure. 
Fraction  I  (b.  p.  120-1600  at  100  Mm.).  This  was  a  colorless, 
limpid  oil  with  a  fragrant  odor.    The  weight  was  11  g. 
Fraction  I  (b.  p.  120-1600  at  10  Mm.).  This  was  a  colorless, 
oil,  less  mobile  than  the  first  fraction,  and  of  about  the  same  weight. 
A  systematic  fractional  distillation  of  I  and  II  effected  no  sep- 
arations. 
Fraction  III  (b.  p.  200-2500  at  10  Mm.).  This  was  a  thick 
viscid  oil  which  partially  solidified.    It  weighed  about  5  g. 
The  fractions  collected  above  2500  at  10  Mm.  solidified  in  the 
receiver.  The  fraction  boiling  at  280-3400  at  10  Mm.  was  crys- 
tallized from  ethyl  acetate.    The  material  melted  at  about  1320,  but
