Exhibition  of  the  Industry  of  All  Nations,  at  New  York,  1853 : 
Chemical  and  Pharmaceutical  Products. — At  this  time,  when  Chem- 
istry plays  so  prominent  a  part  in  the  progress  of  science,  of  medicine  and 
pharmacy,  and  of  the  ornamental  arts  and  manufactures,  it  was  to  be  ex- 
pected that  the  chemical  manufacturer  would  figure  largely  in  an  exhibition 
claiming  to  represent  the  industry  of  all  nations.  After  a  pretty  thorough 
examination  of  what  has  been  sent,  we  confess  to  a  feeling  of  disappoint- 
ment as  regards  our  own  as  well  as  foreign  countries,  in  several  of  which 
this  branch  of  manufacture  is  carried  on  to  an  extent  and  with  a  success 
not  known  here.  The  committee  of  arrangement  have  placed  chemical  and 
pharmaceutical  products  and  processes  in  the  same  class  as  the  coloring 
substances  and  dyes  and  some  miscellaneous  articles.  Of  the  fifty-one  de- 
posites  from  the  United  States,  noticed  in  the  published  list,  fourteen  are 
colors  and  paints,  eight  miscellaneous,  ten  pharmaceuticals,  and  nineteen 
chemicals.  The  finest  display  both  as  regards  quantity,  variety,  and  rarity 
is  that  of  Powers  &  Weightman,  of  Philadelphia.  The  most  conspicuous 
item  is  a  cylindrical  tumbler-shaped  mass  of  alum,  weighing  many  hundred 
weights,  just  as  taken  from  the  crystallizer,  except  that  a  section  has  been 
removed  by  the  saw  to  exhibit  the  beauty  of  the  interior.  Among  the 
liquids  we  observed  acetone,  chloroform,  butyric  acid,  butyric  ether,  acetic 
acid,  acetic  ether,  acetic  amylic  ether,  valerianic  acid,  lactic  acid,  and  the 
oils  of  cloves,  caraway,  copaiba,  black  pepper,  and  pimento.  Among  the 
solids,  the  sulphates  of  quinia  and  morphia,  strychnia  and  its  salts,  brucia, 
santonin,  cafiein,  meconin,  menispermia,  gallic  acid,  lactate  of  iron,  iron  by 
hydrogen,  cyanide  of  copper,  &c. 
Rosengarten  &  Denis,  of  Philadelphia,  exhibit  nitrate  of  silver,  sulphate 
of  quinia,  strychnia,  sulphate  of  strychnia,  veratria,  sulphate  of  morphia, 
and  piperin.    The  sulphate  of  quinia  in  this  lot  was  particularly  fine. 
Charles  Pfizer  &  Co.,  of  New  York,  exhibit  refined  camphor  in  discs, 
napthaline,  benzole,  kreasote,  calomel,  corrosive  sublimate,  and  red 
precipitate. 
Among  the  pharmaceutical  preparations,  the  powdered  drugs  of  Haskell, 
Merrick  &  Bull,  of  New  York,  the  vegetable  extracts  prepared  in  vacuo  by 
Tilden  &  Co.,  of  New  Lebanon ;  the  extract  of  valerian  from  American 
grown  root,  and  colorless  oil  of  wintergreen,  by  David  Parker,  of  the 
Shakers  of  New  Hampshire  ;  the  magnesia  of  Thomas  J.  Husband,  of  Phila- 
delphia ;  and  the  general  display  of  Pharmaceutical  preparations  of  C.  Ellis 
&  Co.,  of  Philadelphia,  deserve  particular  mention. 
Great  Britain. — The  British  contribution  is  very  meagre,  but  a  few  of  the 
numerous  noted  English  and  Scotch  manufacturing  chemists  are  rep- 
resented.
