  67, 
  68.) 
  The 
  foramina 
  of 
  the 
  right 
  side 
  are 
  smaller 
  than 
  those 
  

   of 
  the 
  left, 
  and 
  exhibit 
  in 
  their 
  proportions 
  a 
  lack 
  of 
  symmetry 
  

   directly 
  dependent 
  on 
  the 
  general 
  inequalities 
  of 
  form. 
  Just 
  in 
  

   front 
  of 
  the 
  left 
  posterior 
  mental 
  foramen 
  is 
  a 
  marked, 
  saucer- 
  like 
  

   depression 
  that 
  does 
  not 
  appear 
  on 
  the 
  right. 
  The 
  inner 
  face 
  of 
  

   the 
  right, 
  and 
  outer 
  face 
  of 
  the 
  left 
  coronoid 
  processes 
  and 
  portions 
  

   of 
  the 
  condyloid, 
  are 
  exceptionally 
  rough 
  ; 
  this 
  may 
  be 
  a 
  diseased 
  

   condition, 
  or 
  more 
  probably 
  due 
  to 
  some 
  dissolving 
  agency 
  acting 
  

   from 
  the 
  direction 
  in 
  which 
  they 
  face 
  — 
  an 
  agency 
  that 
  entirely 
  

   removed 
  the 
  right 
  condyle. 
  

  

  Skull. 
  — 
  The 
  buccal 
  ridge 
  upon 
  the 
  right 
  side 
  is 
  very 
  prominent, 
  

   but 
  on 
  the 
  left 
  nearly 
  obliterated. 
  On 
  the 
  right 
  it 
  divides 
  before 
  

   the 
  fifth 
  molar 
  so 
  as 
  to 
  enclose 
  a 
  vacant, 
  quadrilateral 
  area(3x2j 
  

   inches), 
  which 
  displays 
  a 
  marked 
  trace 
  of 
  a 
  tooth 
  socket. 
  The 
  

   left 
  ridge 
  does 
  not 
  define 
  an 
  area 
  before 
  the 
  molar, 
  but 
  indicates 
  

   a 
  termination 
  of 
  the 
  dental 
  groove 
  two 
  inches 
  in 
  advance. 
  The 
  

   palate 
  bones 
  are 
  unsymmetrical 
  anteriorly, 
  the 
  left 
  being 
  twice 
  as 
  

   broad 
  as 
  the 
  right; 
  and 
  the 
  right 
  articulation 
  for 
  styloid 
  process 
  

   is 
  half 
  an 
  inch 
  in 
  advance 
  of 
  the 
  left. 
  The 
  left 
  tusk 
  is 
  somewhat 
  

   the 
  larger 
  and 
  has 
  a 
  different 
  direction. 
  In 
  mounting 
  it, 
  a 
  posi- 
  

   tion 
  too 
  much 
  at 
  variance 
  was 
  given 
  by 
  the 
  warped 
  insertion. 
  Its 
  

   fragmental 
  condition 
  left 
  the 
  shape 
  of 
  the 
  inserted 
  portion 
  the 
  

   only 
  guide 
  for 
  position, 
  and 
  it 
  proved 
  untrustworthy. 
  

  

  The 
  projections, 
  upon 
  the 
  medial 
  plane 
  of 
  the 
  skull, 
  of 
  the 
  

   grinding 
  surfaces 
  of 
  the 
  two 
  sides 
  make 
  with 
  each 
  other 
  an 
  angle 
  

   of 
  26°. 
  The 
  front 
  of 
  the 
  fifth 
  left 
  molar 
  is 
  two 
  inches 
  and 
  eight- 
  

   tenths 
  above 
  the 
  right, 
  and 
  the 
  back 
  of 
  the 
  sixth 
  left, 
  about 
  three 
  

   inches 
  and 
  eight-tenths 
  below 
  the 
  right. 
  Supposing 
  the 
  left 
  side 
  

   normal, 
  the 
  right 
  dental 
  row 
  had 
  dropped 
  down 
  anteriorly 
  in 
  

   search 
  of 
  antagonism, 
  and 
  been 
  retained 
  behind 
  by 
  a 
  process 
  of 
  

   the 
  palate 
  bone. 
  

  

  Comparisons. 
  — 
  The 
  Warren 
  Mastodon, 
  by 
  virtue 
  of 
  its 
  nearly 
  

   complete 
  condition 
  and 
  excellent 
  preservation, 
  of 
  its 
  maturity 
  and 
  

   great 
  size, 
  and 
  of 
  the 
  scientific 
  description 
  it 
  has 
  received, 
  is 
  

   entitled 
  to 
  rank 
  as 
  the 
  representative 
  and 
  standard 
  specimen 
  of 
  

   the 
  species. 
  For 
  this 
  reason, 
  the 
  dimensions 
  of 
  the 
  Cohoes 
  skeleton 
  

   are 
  contrasted 
  above 
  with 
  those 
  of 
  the 
  Warren, 
  and 
  it 
  is 
  deemed 
  

   proper 
  to 
  describe 
  some 
  of 
  the 
  individual 
  peculiarities 
  of 
  the 
  one 
  

   by 
  a 
  comparison 
  with 
  the 
  other. 
  In 
  height 
  our 
  skeleton 
  is 
  ten 
  

   per 
  cent, 
  less 
  than 
  the 
  Warren; 
  clothed 
  in 
  flesh, 
  they 
  were 
  respec-
