NOTES  ON  ESSENTIAL  OILS.1 
AMERICAN  PHARMACOPCEIA  (u.  S.  P.) 
On  the  part  ot  the  American  Pharmacopoeia  Committee,  Supple, 
ments  to  the  U.  S.  P.  have  been  published  on  May  I  and  June 
I,  1907,  which  contain  partly  corrections  of  various  statements, 
and  partly  additions  to  the  individual  articles.  In  the  case  of  the 
essential  oils,  various  alterations  have  also  been  made,  but  unfortun- 
ately not  to  such  an  extent  as  in  our  opinion  appeared  desirable. 
We  quote  the  various  data  below  without  comment,  as  all  further 
particulars  are  found  in  our  previous  discussion  of  the  Pharmacopoeia 3 
to  which  we  here  beg  to  refer. 
Anise  Oil. — d25C  0-975  to  0-988  ;  aD  25  0  to  —  2°. 
Caraway  Oil. — d25  0  0-900  to  0  9 10. 
Copaiba  Oil. — The  requirement  of  solubility  has  been  cancelled. 
Erigeron  Oil? — aD25o  not  below  -f  45  °.

'  It  should  be  mentioned  here  still  that  in  recent  times  we  have  had  to  deal 
repeatedly  with  authentic  erigeron  oils,  which  had  a  distinctly  higher  specific 
gravity  than  that  allowed  by  the  American  Pharmacopoeia,  the  specific  gravities 
of  the  oils  in  question  amounted  up  to  0-887  at  ^corresponding  to  o#88i  at  ^
