DANISH  PHARMACOPOEIA  (PHARMACOPCEIA  DANICA,  I9O7). 
A  new  edition  of  the  Danish  pharmacopoeia  has  now  also  made 
its  appearance,  a  fact  which  induces  us  to  discuss  here  the  articles 
dealing  with  essential  oils  in  a  like  manner  as  in  a  case  of  the  other 
pharmacopoeias  of  which,  up  to  now,  new  editions  have  been  pub- 
lished. 
As  compared  with  the  old  Pharmacopoeia  danica,  1893,  no  addi- 
tional directions  for  testing  have  been  given,  so  that  generally  only 
the  color,  odor,  specific  gravity,  and  solubility  are  taken  into  con- 
sideration. On  the  other  hand,  a  whole  number  of  erroneous  state* 
ments  in  the  old  Pharmacopoeia  have  been  corrected,  and  the 
requirements  specified  by  the  new  edition  may  be  characterized 
almost  without  exception  as  being  to  the  point. 
No  oil  has  been  newly  added,  but  several  oils  hitherto  official  are 
now  no  longer  included,  for  example  bergamot  oil,  cajeput  oil,  cassia 
oil,  oil  of  juniper  berries,  mace  oil,  oil  of  sweet  marjoram,  mustard 
oil,  and  crude  oil  of  turpentine. 
The  alcohols  which  come  under  consideration  for  testing  the  oils, 
are  alcohol  (Vinaand,  Spiritus  concentratus)  with  90  to  91  per  cent,
