CITRONELLOL  ACCORDING  TO  TIEMANN  AND  SCHMIDT. 
Isoamylalcohol  CsHnOH,  with  one  of  its  isomerics  was  pro- 
duced from  the  first  runnings  of  the  distillation  of  Reunion-oil 
(Schimmel,  Ber.,  1904,  I,  p.  51). 
A  parafrine  was  found  by  Barbier  and  Bouveault  (Compt.  Rend. 
CXIX  1894,  p.  281).  It  was  discovered  in  the  remainders  of  the 
distillation  in  the  vacuum.  It  is  of  crystalline  quality  and  melts 
near  63 0  C.  Its  insolubility  in  10  per  cent,  alcohol  permits  the  con- 
clusion that  it  is  a  parafrine. 
Phellandrene  CioH16,  a  monocyclic  terpene.  It  was  identified  in 
the  first  runnings  of  Reunion-oil  (Schimmel,  Ber.,  1904,  I,  p.  51). 
Pinene  CxoH1G,  a  bicyclic  terpene.  It  was  produced  with  the 
preceding  from  the  first  runnings  of  the  Reunion-oil  (Schimmel, 
Ber.,  1904,  I,  p.  51).
