FRACTION  IX. 
The  bottle  containing  this  fraction  was  about  one-quarter  filled, 
well  stoppered,  and  showed  no  crystals  on  its  surface.  The  oil 
possessed  a  faint  terebinthinate  odor,  and  was  almost  colorless.  It 
had  separated  into  two  strata. 
The  lower  stratum  was  colorless,  and  possessed  a  terebinthinate 
odor.  The  relative  density  of  the  dehydrated  oil  at  20°  C.  was 
found  to  be  0-8483.  In  a  100  mm.  tube  it  deviated  the  plane  of 
polarized  light  31-666°  to  the  left,  hence  (a)  D  equals  —  37'332°. 
Upon  analysis  it  yielded  the  following  results  : 
I.    0-1928  gms.  of  substance  yielded  0-6048  C02  =  0*16493  C. 
and  o*2ii6  H20  =  0*0235  H. 
II.    0*2736  gms.  of  substance  yielded  0*864    C02  =  0*2356  C. 
and  0-2946  H20  =  0-0323  H.

The  upper  stratum  was  barely  colored,  possessed  a  pleasant 
fragrance,  reminding  of  lemon  oil.  After  dehydration  the  rela- 
tive density  was  found  to  be  0-8257  at  23 0  C.  In  a  100  mm.  tube  it 
deviated  the  plane  of  polarized  light  13*637°  to  the  left,  hence  its 
(a)  D  equals  — 16-527  at  23°  C. 
Upon  analysis  it  yielded  the  following  results  : 
I.    0-1758  gms.  of  substance  yielded  0-3959  C02  =  0-10797  C. 
and  0*1996  H20  =  0*02217  H. 
II.    0*1997  gms.  of  substance  yielded  0*457    C02  =  0*124635  C.

The  quantity  of  this  fraction  was  not  sufficient  to  allow  of  further 
experimentation.
