An  analysis  of  Simmens  (Pharmac.  Journ.,  XCI,  1913,  p.  143) 
indicates  the  following  values  of  geraniol  and  citronellol  for  the  dif- 
ferent oils : 
Total- geraniol.  Citronellol, 
Algeria,  69.3-79.5  p.  c.  32-43  p.  c. 
Reunion,  69.7-73     "  44-51  " 
Corsica,  69.8         "  30.3  " 
Another  account  (Perfum.  Record,  IV,  1913,  p.  328,  says  that 
by  the  methods  of  acetic  acid  and  formic  acid  the  following  values 
had  been  found  in  six  different  geranium-oils,  of  which,  however, 
the  two  last  must  be  referred  to  cymbogon  species. 
Total-geraniol.  Citronellol. 
France,  72.7  p.  c.  39.8  p.  c.

The  analysis  of  the  pelargonium-oil  which  has  been  produced  in 
Sicily  gave,  according  to  Umney  and  Bennet  (Pharm.  Journal, 
LXXV,  1905,  p.  860;  Chemist  and  Druggist,  LXVII,  1905,  p.  970), 
the  following  results :  Geranyltiglinate  35.6  per  cent.,  total-geraniol 
71.9  per  cent.  The  contents  of  esters  were  greater  than  in  French 
and  Algerian  oils  and  almost  equaled  those  which  had  been  observed 
in  Reunion-oil.
