  ptolites

  31, 
  half 
  a 
  mile 
  farther

  may 
  

   be 
  taken 
  to 
  suggest 
  that 
  we 
  have 
  here 
  a 
  separate 
  horizon. 
  If 
  

   those 
  beds 
  dp 
  not 
  represent 
  another 
  zone, 
  but 
  only 
  a 
  part 
  of 
  the 
  

   upper 
  Dicellograptas 
  zone, 
  the 
  Diplograptus 
  amplexicaulis 
  zone 
  

   would 
  seem 
  partly 
  to 
  overlie 
  with 
  its 
  beds 
  at 
  Watervliet, 
  

   and 
  partly 
  to 
  be 
  intercalated 
  into, 
  the 
  lower 
  Dicellograptus 
  

   zone, 
  at 
  station 
  27, 
  east 
  of 
  Mt 
  Olympus, 
  an 
  irregularity 
  which 
  

   may 
  he 
  also 
  caused 
  by 
  the 
  complicated 
  folding 
  of 
  the 
  region, 
  

   which 
  partakes 
  of 
  the 
  nature 
  of 
  an 
  anticlinorium 
  {see 
  p. 
  557). 
  

   The 
  entire 
  problem,

  of 
  the 
  relation 
  of 
  these

  the

  Dicellograptus 
  and 
  Diplograptus

  awaits 
  its 
  solution 
  in

  high

  a 
  fossiliforous

  These
