﻿PRELIMINARY 
  REMARKS.

  white 
  gold, 
  yet 
  I 
  am 
  not 
  aware 
  of 
  there 
  being 
  any 
  specimen 
  of 
  the 
  

   Burmese 
  metal 
  here 
  in 
  Calcutta, 
  and 
  my 
  endeavours 
  to 
  procure 
  some 
  in 
  

   Rangoon 
  have 
  hitherto 
  been 
  fruitless. 
  The 
  most 
  curious 
  point 
  connected 
  

   with 
  this 
  alloy, 
  is 
  the 
  very 
  large 
  amount 
  contained 
  in 
  it 
  of 
  the 
  com- 
  

   paratively 
  scarce 
  metals 
  iridium 
  and 
  osmium 
  ; 
  but 
  till 
  other 
  samples 
  of 
  

   this 
  curious 
  compound 
  are 
  available 
  for 
  examination, 
  there 
  is 
  little 
  use 
  

   speculating 
  on 
  the 
  cause 
  of 
  the 
  curious 
  proportions 
  of 
  the 
  components 
  

   of 
  the 
  assay

  gives 
  some 
  particulars 
  of 
  the 
  earth-oil 
  wells 
  of

  ; 
  but 
  I 
  will 
  

   only 
  extract 
  the 
  interesting 
  information 
  of 
  the 
  price 
  at 
  which 
  the 
  oil 
  was 
  

   then 
  selling, 
  viz., 
  at 
  the 
  wells, 
  at 
  seven 
  annas 
  and 
  seven 
  pies 
  per

  and
