  Summary. 
  

  

  It 
  may 
  be 
  well 
  to 
  sum 
  up 
  in 
  few 
  words 
  the 
  views 
  advanced 
  in 
  

   this 
  paper 
  : 
  

  

  An 
  early 
  savage 
  condition 
  of 
  mankind 
  when 
  escape 
  from 
  

   terrestrial 
  beasts 
  and 
  the 
  procuring 
  of 
  food 
  forced 
  upon 
  him 
  

   an 
  arboreal 
  habit. 
  Compared 
  with 
  our 
  modern 
  apes 
  a 
  case 
  of 
  

   analogous 
  variation. 
  

  

  The 
  abandonment 
  of 
  this 
  habit 
  and 
  modification 
  of 
  the 
  

   skeleton 
  into 
  what 
  is 
  now 
  regarded 
  as 
  the 
  normal 
  type. 
  

  

  Direct 
  inheritance 
  of, 
  or 
  reversion 
  to, 
  the 
  primitive 
  structures. 
  

  

  In 
  this 
  way 
  we 
  account 
  for 
  the 
  peculiarities 
  shown 
  in 
  the 
  

   skeleton 
  of 
  our 
  Canandaigua 
  warrior.

   D. 
  C, 
  I 
  have 
  just 
  been 
  enabled 
  to 
  read 
  the 
  discussion 
  which 
  followed 
  the 
  presentation 
  of 
  

   Manouvrier's 
  paper, 
  above 
  referred 
  to, 
  January 
  6, 
  1887. 
  In 
  this 
  discussion 
  I 
  find 
  the 
  subject 
  

   of 
  tree-climbing 
  came 
  up, 
  but 
  was 
  not 
  believed 
  by 
  him 
  to 
  have 
  been 
  sufficiently 
  frequent 
  amongst 
  

   Neolithic 
  men 
  to 
  bring 
  about 
  the 
  observed 
  modification 
  of 
  the 
  tibia. 
  In 
  meeting 
  the 
  suggestion 
  

   that 
  it 
  might 
  be 
  an 
  hereditary 
  character, 
  he 
  remarked 
  that 
  in 
  so 
  attempting 
  to 
  explain 
  it, 
  the 
  

   difficulty 
  is 
  simply 
  pushed 
  backward, 
  that 
  there 
  still 
  remains 
  the 
  explanation 
  of 
  how 
  it 
  was 
  

   produced 
  in 
  the 
  ancestors 
  and 
  that 
  we 
  must 
  eventually 
  arrive 
  at 
  an 
  anatomical-physiological 
  

   analysis. 
  Such 
  an 
  explanation 
  would 
  be 
  required 
  only 
  amongst 
  those 
  peoples 
  in 
  which 
  these 
  

   agencies 
  which 
  he 
  considered 
  responsible 
  for 
  the 
  character 
  had 
  been 
  inoperative.
