  Notice 
  of 
  the 
  Plymouth 
  Meteorite. 
  55 
  

  

  Its 
  surface 
  is 
  deeply 
  eroded 
  by 
  oxidization, 
  so 
  that, 
  although 
  

   sound 
  and 
  free 
  from 
  scales, 
  it 
  shows 
  no 
  signs 
  of 
  an 
  original 
  

   crust. 
  .The 
  characteristic 
  pittings 
  of 
  meteorites 
  are 
  also 
  by 
  

   the 
  same 
  cause 
  rendered 
  somewhat 
  feeble, 
  although 
  still 
  quite 
  

   clearly 
  visible. 
  We 
  have 
  cut 
  a 
  number 
  of 
  thin 
  slices 
  from 
  the 
  

   mass. 
  These 
  etched 
  in 
  dilute 
  nitric 
  acid 
  give 
  very 
  clear 
  Wid- 
  

   manstatten 
  figures, 
  which 
  are 
  well 
  shown 
  in 
  the 
  accompanying 
  

   cut 
  (fig. 
  2.) 
  There 
  are, 
  further, 
  several 
  small 
  nodules 
  of 
  

   troilite.

  A 
  careful 
  analysis 
  of 
  this 
  iron 
  has 
  been 
  very 
  kindly 
  made 
  

   for 
  me 
  by 
  Mr. 
  J. 
  M. 
  Davison 
  of 
  the 
  Reynolds 
  Laboratory 
  of 
  

   the 
  University 
  of 
  Rochester, 
  and 
  I 
  give 
  the 
  same

  This 
  iron, 
  herein 
  briefly 
  noticed, 
  is 
  interesting 
  in 
  many 
  ways, 
  

   and 
  it 
  is 
  much 
  to 
  be 
  regretted 
  that 
  the 
  large 
  mass, 
  of 
  which 
  the 
  

   record 
  seems 
  to 
  me 
  to 
  be 
  entirely 
  reliable, 
  cannot 
  be 
  re-dis- 
  

   covered.
