  Gravels. 
  

  

  right 
  and 
  left, 
  present 
  very 
  deep 
  and 
  well-defined 
  sulci, 
  and 
  

   are 
  therefore 
  recognized 
  as 
  female. 
  Of 
  the 
  two 
  human 
  indi- 
  

   viduals, 
  the 
  larger, 
  supposed 
  to 
  be 
  male, 
  was 
  represented 
  by 
  

   the 
  following 
  bones 
  : 
  a 
  series 
  of 
  ten 
  dorsal 
  and 
  lumbar 
  verte- 
  

   brae 
  in 
  nearly 
  perfect 
  articulation 
  with 
  each 
  other 
  and 
  with 
  

   the 
  sacrum, 
  the 
  left 
  ilium 
  still 
  in 
  contact 
  with 
  the 
  sacrum, 
  the 
  

   distal 
  two-thirds 
  of 
  the 
  left 
  femur, 
  the 
  proximal 
  part 
  of 
  the 
  

   left 
  tibia, 
  the 
  left 
  fibula 
  in 
  two 
  fragments, 
  the 
  distal 
  half 
  of 
  

   the 
  right 
  humerus, 
  and 
  a 
  few 
  more 
  or 
  less 
  fragmentary 
  ribs. 
  

   The 
  smaller 
  individual, 
  female, 
  was 
  represented 
  by 
  only 
  a 
  few 
  

   bones, 
  namely 
  : 
  the 
  first 
  sacral 
  vertebra, 
  the 
  left 
  ilium, 
  and 
  the 
  

   articular 
  portion 
  of 
  the 
  right, 
  the 
  left 
  humerus, 
  and 
  the 
  left 
  

   radius. 
  There 
  were 
  also 
  an 
  incisor 
  tooth, 
  a 
  coccygial 
  vertebra,

  the

  the 
  

   place 
  shown 
  in

  a 
  patella, 
  and 
  a 
  few 
  podial 
  bones 
  that 
  may 
  belong 
  to 
  either 
  

   individual. 
  No 
  other 
  human 
  bones 
  were 
  found 
  at 
  this 
  place 
  

   although 
  the 
  gravel 
  surrounding 
  the 
  bones 
  was 
  excavated 
  

   freely 
  in 
  the 
  hope 
  of 
  finding 
  more. 
  The 
  position 
  of 
  some 
  of 
  

   the 
  principal 
  bones, 
  relative 
  to 
  the 
  face 
  of 
  the 
  cut 
  bank, 
  is 
  

   shown 
  in 
  fig. 
  4. 
  The 
  series 
  of 
  dorsal, 
  lumbar 
  and 
  sacral 
  verte- 
  

   brae 
  lay 
  in 
  a 
  nearly 
  horizontal 
  plane 
  with 
  the 
  ventral 
  surfaces 
  

   uppermost. 
  The 
  unnatural 
  position 
  of 
  the 
  left 
  femur 
  and 
  tibia 
  

   underneath 
  the 
  pelvis, 
  and 
  the 
  absence 
  of 
  the 
  skull 
  and 
  ante- 
  

   rior 
  vertebrae, 
  while 
  the 
  rest 
  of 
  the 
  vertebral 
  column 
  is 
  so 
  

   well 
  preserved, 
  are 
  conditions 
  not 
  likely 
  to 
  occur 
  in 
  an 
  undis- 
  

   turbed 
  grave. 
  Although 
  some 
  of 
  the 
  bones 
  may 
  have 
  been 
  

   removed 
  with 
  gravel 
  cut 
  away 
  by 
  the 
  road-menders, 
  this 
  would 
  

   not 
  explain 
  the 
  peculiar 
  disarrangement 
  of 
  the 
  rest. 
  The 
  con- 
  

   ditions 
  described 
  can 
  best 
  be 
  accounted 
  for 
  on 
  the 
  supposition 
  

   that 
  the 
  original 
  interment 
  was 
  made 
  higher 
  up 
  on 
  the 
  cliff 
  — 
  

   perhaps 
  at 
  the 
  top 
  — 
  and 
  that 
  subsequently, 
  when 
  one 
  of 
  the 
  

   small 
  landslips 
  that 
  have 
  built 
  up 
  the 
  talus 
  occurred, 
  the 
  con- 
  

   tents 
  of 
  the 
  grave 
  were 
  dislodged 
  and 
  carried 
  down 
  to 
  the 
  foot
