EXAMINATION  OF  ALCOHOLIC  LIQUIDS  TO  ASCERTAIN  THEIR 
ORIGIN. 
By  M.  Molnar. 
According  to  this  author,  this  process  is  applicable  to  alcoholic 
liquids  which  have  apparently  no  foreign  odor.  It  consists  in 
introducing  sixty  grammes  of  the  spirit  to  be  examined  into  a 
flask  containing  two  or  three  decigrammes  of  caustic  potassa 
dissolved  in  water.  It  is  well  agitated,  and  the  whole  is  sub- 
jected to  evaporation  until  only  five  or  six  grammes  remain. 
Then  the  residue  is  put  into  a  bottle  with  a  glass  stopper,  and 
about  five  grammes  of  dilute  sulphuric  acid  are  added ;  the 
characteristic  odor  is  immediately  diffused ;  this  is  especially  true 
with  regard  to  spirit  from  grain  and  from  beet-root. 
M.  Molnar  mentions  incidentally  that  he  has  always  succeeded 
in  purifying  spirituous  liquors  and  freeing  them  from  their 
essential  oils,  by  using  caustic  potassa  concurrently  with  recently- 
calcined  wood-charcoal. — London  Chemist,  March,  1858,  from

REMOVAL  OF  WARTS  BY  CHROMIC  ACID. 
By  I.  L.  Crawcour,  M.  D.,  etc. 
In  a  late  number  of  the  Medical  Times  and  Gazette  appeared 
some  experiments  by  Mr.  Marshall,  on  the  use  of  chromic  acid. 
Two  cases  have  recently  come  under  my  own  observation,  and 
the  results  have  been  very  satisfactory.  A  gentleman  called  on 
me  about  three  months  ago,  complaining  of  a  wart  on  the  top  of 
his  head ;  it  was  about  the  size  of  a  twenty-five  cent  piece,  and 
the  extremity  was  rough  and  split  vertically.  He  had  suffered 
from  it  for  several  years,  and  it  gave  him  a  great  deal  of  trouble, 
bleeding  whenever  he  combed  his  head.  I  painted  it  thoroughly 
by  means  of  a  glass  brush,  with  a  saturated  solution  of  chromic 
acid.  The  remedy  produced  little  pain,  the  surface  of  the  wart 
instantly  blackened,  and  twelve  days  afterwards  a  scab  fell  oif, 
leaving  a  clear  reddish  surface  underneath,  and  perfectly  smooth. 
I  examined  this  gentleman's  head  a  few  days  ago ;  the  skin  is 
now  perfectly  healthy,  and  hair  is  growing  on  it.    About  two
