  This 
  ore 
  occurs 
  on 
  the 
  farm 
  of 
  H. 
  I. 
  Cruger, 
  Esq., 
  in 
  West- 
  

   chester 
  county. 
  It 
  was 
  furnished 
  for 
  analysis 
  by

   Beck, 
  M. 
  D. 
  When 
  applied 
  as 
  a 
  pigment, 
  it 
  has 
  somewhat 
  the 
  

   appearance 
  of 
  a 
  bronze. 
  It 
  is 
  easily 
  pulverised 
  to 
  a 
  great 
  degree 
  

   of 
  fineness, 
  has 
  a 
  greasy 
  feel, 
  and 
  contains 
  a 
  small 
  per 
  centage 
  of 
  

   an 
  oily 
  unctuous 
  body 
  which 
  is 
  readily 
  volatilized 
  by 
  heat. 
  The 
  

   following 
  are 
  the 
  results 
  of 
  an 
  analysis 
  : 
  

  

  100 
  grains 
  deprived 
  of 
  water,

  The 
  oily 
  matter 
  has 
  an 
  aromatic 
  odor 
  resembling; 
  that 
  of 
  some 
  

   species 
  of 
  laurus. 
  When 
  exposed 
  to 
  destructive 
  distillation 
  

   it 
  passes 
  off 
  in 
  white 
  vapors, 
  which 
  are 
  so 
  pungent 
  as 
  to 
  excite 
  

   when 
  breathed, 
  coughing, 
  and 
  a 
  sense 
  of 
  suffocation. 
  When 
  in- 
  

   haled 
  through 
  the 
  nose, 
  they 
  give 
  rise 
  to 
  a 
  sharp, 
  burning 
  pain 
  

   of 
  the 
  Schneiderian 
  membrane, 
  which 
  persists 
  for 
  some 
  time 
  after 
  

   the 
  inhalation.
