bromine,  boils  at  93-95°  (15  mm.  pressure),  is  laevogyre,  and  at 
20°  C.  has  the  specific  gravity  0-8691.  Beiides  this  ester  there  are 
present  in  the  oil  a  higher  boiling  sesqui-terpene  and  other 
oygenated  constituents  which  naturally  modify  the  odor  of  the 
aurantiol  acetate. 
Oil  of  Lavender,  of  English  origin,  contained  77-53  per  cent, 
carbon  and  1 1-47  per  cent,  hydrogen  ;  the  very  first  portions  of  the 
distillate  (15  mm.  pressure)  contained  terpenes,  among  which 
limonene  was  identified  ;  the  principal  fraction,  85—91  °,  consists  of 
an  unsaturated  alcohol,  C10HlsO,  called  lavcndol,  which  has  a 
specific  odor,  a  density  of  0-8672  at  200  C.  and  is  laevogyre;  at 
97-105 0  a  fraction  (about  10  per  cent.)  was  obtained,  which  proved 
to  be  lavendol  acetate,  specific  gravity  0-8972  at  200  and  laevogyre  ; 
higher  boiling  constituents  were  sesqui-terpene  and  other  oxygenated 
products  to  which  in  part  is  due  the  characteristic  odor  of  the  oil. 
The  physical  and  chemical  properties  of  linalool,  aurantiol  and 
lavendol,  which  so  closely  agree,  suggest  that  they  are  identical ; 
by  reduction  they  yield  aldehydes  or  ketones  of  the  formula 
C10H16O,  having  the  odor  of  geranial  and  from  which  they  cannot 
be  positively  distinguished.  The  alcohols,  under  various  influences, 
retain  their  characteristic  odor  and  certain  physical  differences,  so 
that  they  at  present  cannot  be  considered  as  being  identical. — F.

Spircea  Ulmaria,  L. — The  dried  flozvers  by  distillation  yielded 
salicylic  acid,  salicyl-aldehyde  (chief  constituent),  methyl  salicylate 
(minute  quantity)  and  an  aromatic  liquid  having  the  odor  of  cou- 
marin.  The  fresh  fruit  yielded  the  first  three  compounds,  but  here 
the  methyl-salicylate  was  the  chief  constituent  and  only  a  minute 
quantity  of  the  aldehyde  was  obtainable.  The  dried  roots  furnished 
traces  only  of  aldehyde,  but  considerable  acid  and  chiefly  methyl 
salicylate.  From  the  fresh  roots  were  isolated  only  traces  of 
aldehyde,  much  acid  and  absolutely  no  methyl  salicylate.  At- 
tempts made  to  isolate  these  principles  by  solvents  indicate  that 
the  flowers  contain  the  acid  and  traces  of  methyl  salicylate  pre- 
formed, but  no  aldehyde ;  the  roots,  especially  the  dried,  contain 
the  acid  and  methyl  salicylate  and  but  little  aldehyde.  The 
results  point  to  the  presence  in  the  flower  of  a  substance  which  by 
decomposition  yields  the  aldehyde ;  treated  with  ether,  cold  alcohol, 
boiling  alcohol,  water,  alcohol  and  lime,  and  acidulated  alcohol,
