  Forty-seventh 
  Report 
  on 
  the 
  State 
  Museum. 
  

  

  produced 
  by^the 
  union 
  of 
  the 
  two 
  fossse 
  (the 
  coronoid 
  and 
  

   olecranon) 
  at 
  the 
  elbow-joint.* 
  These 
  bones 
  from 
  the 
  Michigan 
  

   mounds 
  were 
  deposited 
  with 
  the 
  Peabody 
  Museum 
  and 
  that 
  of 
  

   Columbia 
  College, 
  a 
  portion 
  of 
  them 
  being 
  described 
  by 
  Prof. 
  

   Wyman 
  in 
  his 
  Fourth 
  and 
  Sixth 
  Annual 
  Keports 
  and 
  in 
  the 
  

   American 
  Journal 
  of 
  Science, 
  January, 
  1874. 
  These 
  discoveries 
  

   furnished 
  Mr. 
  Gillman 
  with 
  material 
  for 
  a 
  number 
  of 
  valuable 
  

   articles, 
  which 
  appeared 
  from 
  1873 
  to 
  1880, 
  as 
  publications 
  of 
  the 
  

   Smithsonian 
  Institution, 
  the 
  American 
  Association 
  for 
  the 
  

   Advancement 
  of 
  Science 
  and 
  the 
  Michigan 
  Pioneer 
  Society. 
  

   Eesearches 
  of 
  the 
  past 
  twenty 
  years 
  have 
  brought 
  to 
  light 
  in 
  

   various 
  parts 
  of 
  the 
  country 
  numerous 
  instances 
  of 
  tibiae 
  more 
  or 
  

   less 
  flattened; 
  more 
  than 
  verifying 
  the 
  prediction 
  of 
  Mr. 
  Gill- 
  

   man 
  : 
  " 
  I 
  can 
  not 
  but 
  believe, 
  from 
  what 
  I 
  have 
  seen, 
  that 
  

   future 
  investigation 
  will 
  extend 
  the 
  area 
  in 
  which 
  this 
  type 
  of 
  

   bone 
  is 
  predominant 
  to 
  the 
  entire 
  region 
  of 
  the 
  Great 
  Lakes, 
  if 
  

   not 
  of 
  the 
  Great 
  West." 
  f 
  Such 
  bones 
  have 
  been 
  reported 
  from 
  

   Wisconsin, 
  Ohio, 
  Illinois, 
  Iowa, 
  Kentucky, 
  Tennessee 
  and 
  Flor- 
  

   ida; 
  have 
  been 
  observed 
  by 
  me 
  in 
  the 
  World's 
  Fair 
  exhibits 
  

   from 
  Missouri 
  and 
  New 
  Jersey 
  and 
  in 
  the 
  Peabody 
  collections 
  

   from 
  Massachusetts 
  and 
  Peru. 
  The 
  type 
  is 
  found 
  to 
  be 
  of 
  common 
  

   occurrence 
  in 
  the 
  prehistoric 
  remains 
  of 
  Arizona, 
  New 
  Mexico, 
  

   Mexico, 
  Oceania 
  and 
  the 
  Grand 
  Canary 
  Islands, 
  associated, 
  as 
  in 
  

   the 
  preceding, 
  with 
  the 
  perforation 
  of 
  the 
  humerus. 
  Indeed, 
  we 
  

   may 
  now 
  reasonably 
  expect 
  that 
  these 
  characters 
  will 
  be 
  found 
  

   wherever 
  ancient 
  remains 
  are 
  brought 
  to 
  light, 
  the 
  percentage 
  

   of 
  occurrences 
  varying, 
  more 
  or 
  less 
  directly, 
  with 
  the 
  antiquity. 
  

   So 
  far 
  as 
  I 
  am 
  aware 
  this 
  prehistoric 
  type 
  has 
  not 
  yet 
  been 
  

   reported 
  from 
  New 
  York, 
  although 
  finds 
  must 
  have 
  been 
  far 
  

   from 
  few. 
  While 
  conducting 
  a 
  field 
  class 
  in 
  geology 
  at 
  the 
  

   Natural 
  Science 
  Camp, 
  on 
  Canandaigua 
  lake, 
  during 
  the 
  

   summer 
  of 
  1893, 
  a 
  well-preserved 
  skeleton 
  was 
  unearthed, 
  which 
  

   will 
  serve 
  as 
  a 
  text 
  for 
  the 
  discussion 
  of 
  platycnemism 
  and 
  its 
  

   associated 
  characters. 
  

  

  * 
  By 
  "perforation 
  of 
  humerus" 
  some 
  authors 
  refer 
  to 
  the 
  supra 
  condyloid 
  foramen, 
  formed 
  

   by 
  an 
  arch 
  of 
  bone 
  just 
  over 
  the 
  internal 
  condyle, 
  giving 
  passage 
  to 
  the 
  great 
  nerve 
  and 
  artery 
  

   of 
  the 
  forearm.
