Now,  barks  that  will  yield  these  quantities  of  sulphate 
of  quinia,  owing  to  their  much  lower  prices,  are  profitably 
worked  by  the  manufacturer  to  the  rejection  of  every  ingredient 
except  the  quinia,  and  there  can  be  no  good  reason  advanced 
why  they  should  not  be  employed.  As  well  might  exception  be 
taken  to  dolomite  as  a  source  of  magnesia  and  its  preparations, 
because  it  contains  lime,  deeming  that  magnesite  only  should  be 
used.  What  is  it  to  the  physician  or  the  apothecary  whether  the 
sulphate  of  copper  he  uses  is  made  from  the  richest  ore  of  Lake 
Superior,  or  old  copper  sheathing,  if  it  is  pure  ?  Why,  at  this 
very  moment  a  prize  of  four  thousand  francs,  offered  to  the 
man  who  shall  discover  an  artificial  method  of  making  quinia,  or 
in  failure  of  that,  find  a  natural  product  that  shall  equal  quinia  as 
an  antiperiodic,  remains  unclaimed  in  the  hands  of  the  treasurer 
of  the  Society  of  Pharmacy  of  Paris,  and  which  was  offered  seve- 
ral years  ago,  in  view  of  the  supposed  approaching  failure  of  the 
natural  source  of  this  important  medicine.  Yet  in  view  of  all 
this,  an  officer  of  the  United  States,  whose  duty  is  to  prevent 
the  importation  of  adulterated  drugs,  medicines  and  medicinal 
preparations,  refuses  entry  to  an  invoice  of  Bogota  bark  because 
it  is  "  one  of  the  varieties  of  Carthagena  bark,  all  of  which  are 
specified  by  the  United  States  Pharmacopeia  and  Dispensatory
