Other  Remedies. — In  connection  with  the  foregoing,  it  may  be 
stated  that  a  number  of  other  remedies  produce  similar  reactions 
when  eliminated  by  the  kidneys. 
Copaiba  and  its  oil  behave  similarly  to  oil  of  turpentine  when 
being  examined  for  albumin. 
When  examined  for  the  latter,  the  urine  may  reveal  the  presence 
of  resin  acids,  and  the  same  means,  their  solubility  in  alcohol,  will 
furnish  the  point  of  distinction. 
Incidentally,  it  may  be  mentioned  that,  after  the  administration 
of  a  large  dose  of  cubeb  and  its  preparations,  an  identical  result  is 
said  to  take  place. 
It  may  likewise  be  surmised  that  many  remedies  of  a  balsamic 
nature  are  liable  to  produce  this  effect. 
Copaiba  urine  will  also  reduce  Fehling's  solution,  but,  according 
to  Quincke,  will  not  affect  the  bismuth  tests.  It  is  readily  distin- 
guished by  its  characteristic  odor  and  the  red  or  purplish  color  it 
develops  when  mixed  with  hydrochloric  or  other  concentrated 
acids. 
The  numerous  synthetical  organic  compounds,  introduced  into 
medicine  within  the  last  few  years,  furnish  a  large  field  for  research 
in  urine  analysis. 
The  elimination  of  a  number  in  the  urine  as  glycuronic  com- 
pounds has  been  studied,  but  many  require  further  investigation. 
They  possess  the  peculiarities  referred  to  in  their  action  upon 
polarized  light,  being  all  laevogyre,  as  well  as  the  reducing  action 
upon  glucose  reagents. 
Some,  however,  do  not  reduce  the  mentioned  test  liquids.  Such 
are  phenolglycuronic  and  camphoglycuronic  acid,  eliminated  after 
the  administration  of  carbolic  acid  and  camphor,  and  the  compounds 
formed  after  the  ingestion  of  antipyrine  and  other  remedies. 
Among  a  number  which  exert  a  reducing  action,  a  few  deserve 
prominent  mention. 
Such  are  acetanilid  or  antifebrin,  kairin,  morphine,  nitrobenzol 
and  bitter  almond  oil,  benzoic  and  salicylic  acids,  and  their  respective 
salts,  together  with  others  of  more  or  less  importance. 
Acetanilid  Urine. — This  deserves,  perhaps,  more  than  passing 
notice.  Urine  passed  after  the  administration  of  this  compound 
readily  reduces  Fehling's  solution  and  responds  to  most  other  sugar 
tests.
