  It 
  has

  the 
  wish 
  of

   maps 
  giving 
  the 
  geological 
  structure 
  and 
  distribution 
  of 
  the 
  several 
  

   formations, 
  and 
  accompany 
  the 
  same 
  by 
  maps 
  showing 
  the 
  

   occurrence 
  and 
  distribution 
  of 
  the 
  economic 
  products 
  of 
  each 
  one 
  

   of
