The  alkaline  liquid  was  distilled  with  water  vapor.  Oil  came 
over  clear  at  first,  but  toward  the  close  of  the  operation  the  distillate 
crystallized.  The  crystals  were  carefully  separated  and  dried  on  a 
porous  plate.    Melting  point,  I98°-I99°  C  ,  in  a  sealed  tube. 
The  oil  was  dried  with  exsiccated  sodium  sulphate.  It  was  color- 
less, of  a  terebinthinate  odor,  specific  gravity  0  8759  at  200  C.  In 
a  100-millimetre  tube,  it  deviated  the  ray  of  polarized  light  26.470 
to  the  left,  hence  (a)D  =  —  30-22°.  The  oil  was  then  fractionated 
for  a  second  time.  Toward  the  close  of  the  operation  the  oil  con- 
gealed in  the  condensing  tube,  and  shortly  after  removing  the  flame, 
the  contents  of  the  flask  crystallized.

A  colorless  oil.  of  a  slight  terebinthinate,  but  mixed  odor,  specific 
gravity  at  20°  C.  =  0  8798.  In  a  100-millimetre  tube  it  turned 
the  plane  of  polarized  light  27-15°  to  the  left;  hence  (#)D  =  — 
30-86°.    Upon  analysis  it  yielded  the  following  results  :

II.  0-1873  gram  yielded  0-5667  g.  CO.  =  C1546  g.  C. ,  and

PINENE  NITROSO-CHLORIDE. 
* 
Since  the  odor  of  the  fraction  reminded  one  of  pinene,  the  nitroso- 
chloride  reaction  was  made.  Five  cubic  centimetres  of  oil  were 
mixed  with  5  cubic  centimetres  of  glacial  acetic  acid  and  6  cubic 
centimetres  of  ethyl  nitrite,  and  placed  in  a  freezing  mixture.  To 
this  was  added,  drop  by  drop,  a  mixture  of  3  cubic  centimetres  of 
glacial  acetic  acid  and  3  cubic  centimetres  of  concentrated  hydro- 
chloric acid,  and  then  5  cubic  centimetres  of  methyl  alcohol.  The 
yield  of  nitroso-chloride  was  very  small,  the  crystals  melting  at 
101°  C.  The  mother  liquid  of  the  nitroso-chloride  was  then  placed 
in  a  freezing  mixture.  Nothing  separated  after  two  hours.  After 
twenty-four  hours  the  mother  liquid  had  become  brown  and  crystals
