   exhibited

   specimens 
  of 
  mica, 
  containing 
  potash,

   which 
  gold 
  was

  in 
  considerable 
  quantity, 
  found 
  at 
  Gran- 
  

   ite 
  Creek, 
  near 
  Coloma 
  — 
  the 
  only 
  specimens, 
  he 
  believed, 
  in 
  which 
  

   gold 
  had 
  been 
  obtained 
  ift 
  any 
  other 
  vein

  mineral

  quartz

   the 
  specimens 
  did 
  not 
  occur 
  continuously, 
  but 
  in 
  patches, 
  and 
  

   occurred 
  in 
  an 
  altered 
  porphyritic 
  rock 
  ; 
  they 
  were 
  a 
  very 
  beauti- 
  

   ful 
  microscopic 
  study, 
  and 
  the 
  formation 
  indicated 
  that 
  the 
  gold 
  

   must 
  have 
  been 
  deposited 
  by 
  aqueous 
  solution 
  between 
  the 
  thin 
  

   flakes 
  of 
  mica.
