  a 
  bone 
  of 
  the 
  leg, 
  or 
  a 
  joint 
  of 
  the 
  vertebra, 
  where 
  no 
  

   other 
  vestiges 
  are 
  seen. 
  

  

  The 
  most 
  prolific 
  locality 
  of 
  these 
  remains 
  is 
  in 
  

   Adams 
  County, 
  on 
  Pine 
  Ridge, 
  in 
  Townships 
  7 
  and 
  8, 
  

   Range 
  3 
  W., 
  about 
  six 
  miles 
  north 
  of 
  Natchez, 
  where 
  a 
  

   large 
  and 
  deep 
  ravine 
  has 
  extended 
  its 
  ramifications 
  over 
  

   an 
  area 
  of 
  several 
  miles, 
  and 
  which, 
  in 
  its 
  undermining 
  

   progress 
  of 
  denudation, 
  has 
  been 
  constantly 
  exposing 
  

   these 
  remains 
  for 
  more 
  than 
  forty 
  years, 
  or 
  from 
  a 
  period 
  

   coeval 
  with 
  the 
  first 
  cultivation 
  of 
  the 
  country 
  throuo'h 
  

   which 
  it 
  has 
  its 
  course. 
  

  

  The 
  bones 
  generally 
  lie 
  from 
  ten 
  to 
  twenty 
  feet 
  below 
  

   the 
  general 
  surface, 
  and 
  in 
  the 
  ravine 
  on 
  Pine 
  Ridge, 
  the 
  

   remains 
  of 
  other 
  animals 
  have 
  been 
  found 
  associated 
  with 
  

   them. 
  

  

  Among 
  these, 
  may 
  be 
  enumerated 
  those 
  of 
  the 
  mega- 
  

   lonyx, 
  an 
  animal 
  provided 
  with 
  claws 
  of 
  great 
  magnitude 
  

   and 
  strength, 
  the 
  bony 
  axis 
  of 
  the 
  nail 
  itself 
  being 
  about 
  

   four 
  inches 
  in 
  length; 
  and 
  the 
  Tapir 
  {Tajnrns 
  Ameri- 
  

   cana), 
  now 
  extinct 
  here, 
  but 
  still 
  living 
  in 
  South 
  Ame- 
  

   rica; 
  a 
  lower 
  maxillary 
  bone 
  containing 
  the 
  molars, 
  

   and 
  some 
  detached 
  teeth, 
  being 
  the 
  only 
  portions 
  of 
  the 
  

   latter 
  known 
  to 
  have 
  been 
  procured. 
  These, 
  together 
  

   with 
  the 
  femur 
  and 
  claws 
  of 
  the 
  megalonyx, 
  have 
  been 
  

   submitted 
  to 
  the 
  examination 
  of 
  Dr. 
  Leidy, 
  who 
  is 
  pre- 
  

   paring 
  a 
  monograph 
  descriptive 
  of 
  them. 
  

  

  Besides 
  these, 
  the 
  teeth 
  of 
  the 
  fossil 
  horse 
  and 
  ox 
  are 
  

   frequently 
  found. 
  Those 
  of 
  the 
  bos 
  are 
  referred 
  by 
  Dr. 
  

   Leidy, 
  in 
  his 
  account 
  of 
  them 
  pubhshed 
  in 
  the 
  fifth 
  

   volume 
  of 
  the 
  Smithsonian 
  Contrihutioyis 
  to 
  Knowled(je, 
  

   to 
  the 
  Bison 
  latifrons. 
  

  

  It 
  would 
  seem, 
  hy 
  the 
  discovery 
  of 
  these 
  remains, 
  that 
  

   the 
  horse, 
  although 
  not 
  found 
  on 
  this 
  Continent 
  when
