  Within 
  the 
  writer's 
  observation, 
  students 
  at 
  the 
  beginning 
  of 
  

   their 
  field 
  experience 
  are 
  misled 
  by 
  the 
  perfection 
  of 
  cabinet 
  

   specimens 
  and 
  figures 
  and 
  hope 
  to 
  find 
  everywhere 
  such 
  perfect 
  

   forms; 
  as 
  a 
  matter 
  of 
  fact, 
  they 
  must 
  learn 
  to 
  be 
  guided 
  for 
  the 
  

   most 
  part 
  by 
  fragments. 
  

  

  It 
  does 
  not 
  seem 
  possible 
  to 
  give 
  within 
  the 
  limits 
  of 
  this 
  publi- 
  

   cation 
  any 
  adequate 
  description 
  of 
  the 
  fossils 
  which 
  are 
  charac- 
  

   teristic 
  of 
  the 
  difi'erent 
  strata. 
  It 
  is 
  better 
  for 
  these 
  to 
  refer 
  to 
  the 
  

   original 
  publications 
  of 
  the 
  New 
  York 
  Natural 
  History 
  Survey. 
  

   In 
  the 
  four 
  reports 
  on 
  geology 
  by 
  Mather, 
  Emmons, 
  Vanuxem 
  and 
  

   Hall, 
  numerous 
  illustrations 
  of 
  fossils 
  are 
  given 
  but 
  the 
  names 
  

   are, 
  in 
  many 
  cases, 
  out 
  of 
  date. 
  In 
  the 
  volumes 
  on 
  Palaeontology 
  

   from 
  I 
  to 
  VII, 
  are 
  described 
  and 
  figured 
  most 
  of 
  the 
  fossils 
  of 
  

   New 
  York 
  state 
  from 
  the 
  Potsdam 
  sandstone 
  to 
  the 
  Chemung. 
  

   Volume 
  VIII 
  gives 
  a 
  revision 
  of 
  the 
  Brachiopoda. 
  To 
  

   these 
  volumes, 
  therefore, 
  the 
  student 
  should 
  refer 
  for 
  the 
  identifi- 
  

   cation 
  of 
  such 
  forms 
  as 
  he 
  may 
  find 
  in 
  his 
  field 
  excursions. 
  A 
  few 
  

   of 
  the 
  more 
  common 
  species 
  are 
  figured 
  in 
  Dana's 
  Manual 
  of 
  

   Geology 
  y 
  which 
  should 
  be 
  in 
  the 
  hands 
  of 
  every 
  student. 
  For 
  those 
  

   pursuing 
  more 
  critical 
  studies, 
  the 
  work 
  of 
  S. 
  A. 
  Miller 
  on 
  North 
  

   American 
  Geology 
  and 
  Palaeontology 
  is 
  of 
  great 
  value 
  as 
  it 
  gives 
  a 
  

   complete 
  list 
  of 
  all 
  Palaeozoic 
  fossils 
  described 
  up 
  to 
  the 
  date 
  of 
  

   its 
  publication 
  and 
  indicates 
  the 
  more 
  modern 
  names 
  in 
  the 
  many 
  

   cases 
  where 
  there 
  has 
  been 
  a 
  change 
  of 
  nomenclature. 
  Of 
  the 
  

   eight 
  volumes 
  of 
  New 
  York 
  palaeontology 
  mentioned, 
  the 
  first 
  

   two 
  are 
  out 
  of 
  print 
  and 
  are 
  only 
  to 
  be 
  had 
  from 
  dealers 
  in 
  second 
  

   hand 
  books, 
  but 
  they 
  will 
  probably 
  be 
  found 
  in 
  most 
  of 
  the 
  public 
  

   libraries 
  of 
  New 
  York 
  state. 
  The 
  remaining 
  volumes 
  are 
  sold 
  at 
  

   *2.50 
  each.

  The

  of 
  the 
  Regents 
  of

   is 
  the 
  result 
  of 
  the 
  geological 
  survey 
  of 
  the 
  state 
  commenced 
  in 
  

   1836.
