﻿FOURTH 
  REPORT

  study 
  of 
  fossil 
  fishes, 
  we 
  may 
  be 
  allowed 
  to 
  recommend 
  all 
  such 
  

   to 
  read 
  the 
  lives 
  of 
  Louis 
  Agassiz 
  and 
  Hugh 
  Miller, 
  especially 
  the 
  

   recent 
  character 
  study 
  of 
  the 
  latter 
  by 
  Mr 
  Mackenzie 
  (1906). 
  An 
  

   answer 
  is 
  recorded 
  there 
  so 
  plainly 
  that 
  he 
  who 
  runs 
  may 
  read. 
  

   Wherever 
  the 
  work 
  of 
  Miller 
  is 
  remembered 
  and 
  appreciated, 
  it 
  is 
  not 
  

   for 
  the 
  value 
  of 
  his 
  discoveries, 
  nor 
  for 
  his 
  contributions 
  to 
  science, 
  

   but 
  for 
  the 
  native 
  shrewdness, 
  clearness, 
  intensity 
  and 
  discernment 
  

   with 
  which 
  he 
  drew 
  philosophical 
  conclusions 
  from 
  the 
  study 
  of 
  

   nature. 
  And 
  his 
  impulse 
  in 
  this 
  direction 
  was 
  first 
  quickened 
  and 
  

   set 
  in 
  motion 
  by 
  his 
  discovery 
  of 
  fish-bearing 
  nodules 
  in 
  the 
  Old 
  Red 
  

   sandstone 
  of 
  the 
  north 
  of 
  Scotland. 
  We 
  can 
  not 
  forbear 
  in 
  this 
  

   connection 
  to 
  quote 
  the 
  following 
  passage 
  from 
  an 
  address 
  delivered 
  

   a 
  few 
  years 
  ago 
  by 
  M. 
  Albert 
  Gaudry, 
  president 
  of 
  one 
  of 
  the 
  

   sections 
  of 
  the 
  French 
  Academy:

  Graptolites 
  of 
  New 
  York. 
  At 
  this 
  writing 
  the 
  second 
  volume 
  

   (Memoir 
  11) 
  of 
  the 
  monograph 
  of 
  the 
  Graptolites, 
  prepared 
  by 
  Dr 
  

   Rudolf 
  Ruedemann 
  is 
  leaving 
  the 
  press. 
  Volume 
  1 
  (Memoir 
  7) 
  

   on 
  the 
  species 
  of 
  the 
  earlier 
  rocks 
  was 
  issued 
  in 
  1905. 
  The 
  present 
  

   work 
  embraces 
  the 
  later 
  forms 
  and 
  completes 
  the 
  subject 
  embracing 
  

   most 
  if 
  not 
  all 
  species 
  reported 
  from 
  the 
  United 
  States 
  of 
  this 
  

   interesting 
  and 
  long 
  extinct 
  group 
  of 
  organisms. 
  In 
  this 
  volume 
  

   there 
  are 
  altogether 
  149 
  species 
  and 
  varieties 
  of 
  graptolites 
  described. 
  

   The 
  greater 
  part 
  of 
  these 
  come 
  from 
  the 
  upper 
  part 
  of 
  the 
  Lower 
  

   Siluric 
  (Champlainic), 
  the 
  great 
  majority 
  from 
  the 
  Trenton 
  shales; 
  

   a 
  smaller 
  part 
  from 
  the 
  Siluric 
  zones 
  distinguished 
  in 
  the 
  upper 
  part 
  

   of 
  the 
  Lower 
  Siluric, 
  which 
  broadly 
  correspond 
  to 
  the 
  Black 
  river 
  

   — 
  lower 
  Trenton, 
  middle 
  — 
  upper 
  Trenton, 
  Utica 
  and 
  Lorraine 
  

   beds. 
  All 
  of 
  these 
  can 
  be 
  correlated 
  with 
  well 
  known 
  Euro- 
  

   pean 
  zones. 
  

  

  In 
  view 
  of 
  the 
  fact 
  that 
  the 
  slate 
  belt 
  of 
  eastern 
  New 
  York 
  has 
  

   furnished 
  a 
  practically 
  complete 
  succession 
  of 
  graptolite 
  beds, 
  ex- 
  

   tending 
  from 
  the 
  top 
  of 
  the 
  Cambric 
  to 
  nearly 
  the 
  top 
  of 
  the 
  Lower 
  

   Siluric, 
  the 
  conditions 
  of 
  deposition 
  of 
  graptolite 
  beds 
  are 
  fully 
  

   investigated 
  and 
  the 
  conclusion 
  reached 
  that 
  graptolite 
  shales 
  are, 
  

   as 
  a 
  rule, 
  deposited 
  in 
  the 
  same 
  region 
  for 
  longer 
  intervals 
  than 
  

   most 
  other 
  fossiliferous 
  rocks. 
  This 
  leads 
  to 
  the 
  inference 
  of 
  the
