REMARKS  ON  THE  ANALYSIS  OF  BRANDY.

acid  test,"  it  remained  unchanged,  proving  the  absence  of  grape 
fusel  oil,  with  which  the  marc  brandies  are  loaded.  Here  was 
evident  proof  that  Chevallier,  Accum,  Normandy,  Hassal  and 
Mitchell  were  correct  in  their  experiences,  and  that  the  tests 
given  were  reliable. 
Shortly  after  this  I  was  written  to  by  a  New  York  house, 
whose  brandy  I  sent  back,  to  give  them  my  system  of  analysis, 
in  order  that  they  could  test  its  accuracy,  by  practical  applica- 
tion, in  their  own  hands.  About  two  weeks  after,  I  received  a 
letter  stating  "they  had  subjected  the  article  I  refused  to  the 
analytical  process  furnished  them,  and  all  was  right,  except  it 
lost  the  6  bouquet,  "  and  he  asks,  "  where  can  this  «  bouquet '  have 
gone  to  ;  it  is  neither  in  the  contents  of  the  retort,  nor  in  the  dis- 
tillate." In  that  very  sentence  he  branded  his  article  impure. 
As  I  held  out  to  have  pure  and  attested  articles,  I  was  con- 
stantly applied  to  to  furnish  pure  brandy,  but  could  not,  for 
upwards  of  two  years,  meet  this  demand. 
Mr.  Charles  Carpenter  came  into  my  laboratory  while  ex- 
perimenting on  the  most  economical  method  of  preparing  oil  of 
wine,  and  showed  me  a  sample  of  what  he  stated  was  pure 
brandy.  1  subjected  it  to  analysis  and  found  it  to  be  of  simi- 
lar character  with  that  manufactured  by  Zimmerman  &  Co., 
though  freer  from  grain  oils  than  the  sample  analyzed  by  Mr. 
E.  S.  Wayne  and  described  in  one  of  the  back  numbers  of  your 
valuable  Journal.  I  described  to  him  what  I  desired,  and  he 
said  he  had  been  to  Cincinnati,  and  there  was  nothing  there 
but  marc  brandy,  and  I  would  seek  in  vain  for  distilled  wine  in 
the  United  States. 
After  an  explanation  of  the  process,  he  agreed  to  distill  me 
twenty  gallons  as  a  trial.  1  send  you  herewith  a  sample,  and 
desire,  if  you  feel  so  disposed  and  have  the  time,  to  subject  it 
to  all  the  tests  known  to  chemists.  The  article  in  question  is 
distilled  from  Catawba  wine  of  three  or  four  years  of  age,  and 
could  be  furnished  at  twelve  dollars  the  gallon.  We  retail  it 
at  sixteen  the  gallon,  paying  the  price  above  for  it,  and  give 
one  ounce  for  the  same  rate,  (one  shilling.)  Of  course  there  is 
not  the  same  amount  of  profit  which  could  be  secured  by  the 
sale  of  common  "  Rochelle  "  at  four  and  six  dollars  per  gallon, 
but  I  trust  that  the  majority  of  apothecaries  of  the  Philadelphia
