The  following  salts  were  also  prepared,  but  as  they  are  not  well 
characterized,  nothing  but  an  analysis  of  them  was  attempted,  and  net 
•even  this  in  all  cases :

PURE  AND  ADULTERATED  OIL  OF  CINNAMON  CASSIA. 
Among  the  adulterations  of  commercial  oil  of  Chinese  cinnamon, 
that  with  rosin  or  a  similar  resin  has  been  repeatedly  referred  to  in 
former  years.  Much  of  this  oil  was  shipped  with  a  certificate  of  gen- 
uineness or  purity  signed  by  Niedhardt,  chemist  of  the  Medical  Hall 
at  Hongkong,  who  after  exposure  attempted  in  various  ways  to 
maintain  the  correctness  of  his  assertions.  The  absurdity  of  these 
claims  have  been  fully  shown  in  the  Report  on  Essential  Oils  by  Schini- 
mel  &  Co.,  of  Leipzig,  for  October,  who,  in  addition,  give  the  follow- 
ing information  on  pure  and  adulterated  cassia  oil  : 
The  owners  of  the  brand  of  ying  chong,  which  has  been  found  to  be 
genuine,  write  us  from  Macao,  that  they  have  suspended  shipments 
for  some  time,  inasmuch  as  the  adulterated  oils,  which  are  being 
offered  at  a  low  price,  had  made  it  impossible  for  them  to  compete. 
They  moreover  remark,  very  much  to  the  point,  that  the  owners  of 
the  adulterated  brands  :  yan  loong,  cheong  loong  and  luen  tai,  had 
evinced  the  utmost  disinclination  to  and  avoided  having  their  oils 
inspected  and  placed  under  supervision  at  Macao.  It  results  from 
authentic  reports  that  the  oil  is  brought  from  the  province  Kwangtung 
to  Macao,  where  it  is  put  up.  Hence  there  is  probably  some  reason 
for-  supposing  that  the  owners  of  the  above  brands,  who,  at  the  time, 
contracted  sales  down  to  as  low  a  price  as  2s.  Id.  per  pound,  effected  the 
adulteration  at  Macao  at  the  ratio  of  the  prices  obtained.  But,  no 
matter  where  the  falsifiers  may  be  located,  it  will  now  be  the  task  of 
the  Hongkong  firms  to  stop  their  nefarious  practices  and,  as  it  is 
surely  preferable,  in  commerce,  to  be  liberal  in  the  matter  of  price 
rather  than  to  buy  resin  in  lieu  of  cassia  oil,  the  matter  will,  after 
some  opposition  on  the  part  of  the  falsifiers,  progress  in  the  right 
groove  of  its  own  accord.
