The  samples  of  gurjun  were  all  secured  in  New  York.  The  two 
latter  items  represent  commercial  oil  of  copaiba,  the  last  is  adulter- 
ated with  oil  of  gurjun  and  the  other  is  pure.  The  specific  gravi- 
ties at  25 0  C.  were  simply  taken  for  data. 
There  is  a  very  limited  demand  for  solidifiable  copaiba,  mass 
copaiba  and  resin  copaiba.  The  article  of  which  large  quantities 
are  used  is  a  copaiba  containing  from  40  to  60  per  cent,  of  oil.  The 
representative  of  a  large  essential  oil  firm  informed  me  that  1,000 
pounds  of  the  latter  were  sold  to  five  pounds  of  the  solidifiable,  and 
three  and  one-half  pounds  of  the  resin.  This  included  the  territory 
from  Detroit,  Mich.,  east  to  the  Atlantic,  through  Canada  and  south 
to  Philadelphia  and  vicinity.  If  the  above  territory  is  at  all  repre- 
sentative of  the  country  covered  by  the  U.S. P.,  it  would  appear  that 
the  commodity  which  is  used  more  than  all  the  other  copaiba 
compounds  ought  to  have  been  recognized  by  our  Pharmacopoeia. 
The  present  requirements  of  the  Pharmacopoeia  for  balsam  copaiba 
(properly  an  oleoresin  of  copaiba)  have  undoubtedly  wrought  hard, 
ships  for  some  well-meaning  druggists.  Only  the  solidifiable  is 
recognized,  and  practically  nothing  but  an  unofficial  article  is  used. 
From  this  it  can  readily  be  seen  that  in  ninety-nine  cases  out  of  a 
hundred  the  average  druggist  is  violating  the  requirements  of  the 
Pharmacopoeia  when  he  dispenses  copaiba,  and  is  thus  rendered  cul- 
pable, especially  in  some  states.
