  distinctly 
  marked 
  ; 
  in 
  the 
  fourth 
  they 
  are 
  smaller 
  still, 
  but 
  wider 
  apart, 
  

   and 
  still 
  preserve 
  the 
  same 
  distance 
  from 
  the 
  anterior 
  border 
  of 
  the 
  

   vertebra. 
  In 
  the 
  sixth 
  they 
  become 
  large 
  again, 
  are 
  less 
  than 
  a 
  

   centimetre 
  apart, 
  and 
  a 
  little 
  more 
  anterior 
  in 
  position. 
  

  

  The 
  sutural 
  line 
  between 
  the 
  vertebras 
  shows 
  that 
  in 
  the 
  region 
  

   of 
  the 
  centrum 
  the 
  outline 
  was 
  convex 
  from 
  above 
  downward 
  in 
  

   front 
  laterally, 
  and 
  concave 
  from 
  side 
  to 
  side 
  at 
  the 
  base 
  in 
  front. 
  

   The 
  sutures 
  between 
  the 
  vertebras 
  are 
  marked 
  by 
  sharp 
  narrow 
  

   grooves, 
  which 
  correspond 
  to 
  ridges 
  on 
  the 
  interior 
  of 
  the 
  bone. 
  The 
  

   suture 
  appears 
  to 
  pass 
  upward, 
  so 
  as 
  to 
  merge 
  into 
  the 
  neuro-central 
  

   suture, 
  which 
  is 
  faint, 
  but 
  best 
  marked 
  in 
  the 
  last 
  vertebra, 
  where 
  

   it 
  passes 
  below 
  the 
  lateral 
  neural 
  foramen. 
  The 
  antero-posterior 
  

   limits 
  of 
  the 
  neural 
  arch 
  correspond 
  closely 
  to 
  the 
  limits 
  of 
  the 
  

   centrum. 
  

  

  The 
  transverse 
  processes 
  are 
  directed 
  forward 
  in 
  front, 
  outward 
  

   in 
  the 
  middle, 
  and 
  backward 
  behind 
  (fig. 
  2). 
  They 
  are 
  given 
  off, 
  

   as 
  nearly 
  as 
  may 
  be, 
  in 
  the 
  line 
  of 
  the 
  lateral 
  intervertebral 
  sutures, 
  

   and 
  just 
  in 
  front 
  of 
  the 
  sutures 
  on 
  the 
  base. 
  There 
  is 
  no 
  evidence 
  

   of 
  any 
  separate 
  bony 
  base 
  to 
  these 
  processes, 
  separating 
  them 
  from 
  

   the 
  neural 
  canal, 
  though 
  such 
  partitions 
  probably 
  existed. 
  The 
  

   first 
  of 
  these 
  processes 
  on 
  the 
  right 
  side 
  is 
  at 
  the 
  fracture 
  4| 
  centim. 
  

   deep, 
  and 
  widens 
  from 
  1 
  centim. 
  above 
  to 
  2j 
  centim. 
  below. 
  It 
  is 
  

   situate 
  just 
  in 
  front 
  of 
  the 
  intervertebral 
  suture. 
  

  

  The 
  attachment 
  of 
  the 
  second 
  process 
  is 
  4*8 
  centim. 
  deep, 
  with 
  its 
  

   base 
  placed 
  a 
  little 
  higher 
  than 
  the 
  first. 
  Its 
  margin 
  is 
  con 
  cave 
  in 
  front 
  ; 
  

   and 
  the 
  concavity 
  appears 
  to 
  have 
  excavated 
  the 
  process 
  much 
  as 
  in 
  

   the 
  first 
  process. 
  The 
  third 
  process 
  is 
  fractured 
  nearer 
  to 
  its 
  base, 
  

   and 
  is 
  less 
  than 
  4 
  centim. 
  deep 
  and 
  about 
  2 
  centim. 
  wide. 
  The 
  

   fourth 
  is 
  smaller 
  ; 
  the 
  fifth, 
  hardly 
  more 
  than 
  \\ 
  centim. 
  deep 
  and 
  

   1 
  centim. 
  wide, 
  diverges 
  conspicuously 
  backward 
  and 
  outward. 
  

  

  The 
  first 
  process 
  on 
  the 
  right 
  side 
  expands 
  outward 
  and 
  forward 
  

   in 
  a 
  subcorneal 
  way, 
  so 
  as 
  to 
  terminate 
  in 
  a 
  large 
  flattened 
  facet 
  

   for 
  the 
  ilium 
  (fig. 
  1, 
  t 
  a), 
  which 
  is 
  vertical 
  in 
  position, 
  though 
  inclined 
  

   somewhat 
  forward, 
  and 
  a 
  little 
  convex 
  from 
  above 
  downward. 
  It 
  is 
  

   11*5 
  centim. 
  deep 
  and 
  7'5 
  centim. 
  wide 
  where 
  widest. 
  The 
  pos- 
  

   terior 
  border 
  is 
  convex, 
  and 
  the 
  posterior 
  side 
  gives 
  off 
  a 
  little 
  

   rounded 
  ridge 
  where 
  it 
  joins 
  the 
  side 
  of 
  the 
  cast 
  of 
  the 
  neural 
  region. 
  

   In 
  front 
  the 
  outline 
  of 
  its 
  articular 
  end 
  is 
  more 
  angular, 
  being 
  

   compressed 
  below 
  and 
  above. 
  A 
  blunt 
  ridge 
  runs 
  on 
  the 
  inner 
  

   side 
  from 
  the 
  middle, 
  and 
  expands 
  upward 
  so 
  as 
  to 
  form 
  the 
  supe- 
  

   rior 
  part 
  of 
  the 
  transverse 
  process 
  at 
  its 
  base, 
  in 
  such 
  a 
  way 
  as 
  to 
  

   give 
  an 
  aspect 
  to 
  the 
  process 
  of 
  being 
  excavated 
  in 
  front. 
  

  

  The 
  transverse 
  processes 
  would 
  give 
  a 
  width 
  to 
  the 
  sacrum 
  in 
  

   front 
  of 
  20 
  centim., 
  which 
  was 
  probably 
  increased 
  towards 
  the 
  

   middle. 
  

  

  Behind 
  the 
  transverse 
  processes 
  . 
  there 
  is 
  a 
  moderate 
  circular 
  

   inflation 
  of 
  the 
  cast, 
  which 
  is 
  conspicuous 
  in 
  all 
  the 
  vertebras, 
  so 
  

   that 
  in 
  front 
  of 
  the 
  neural 
  foramen 
  there 
  is 
  a 
  somewhat 
  convex 
  

   rugose 
  tubercle, 
  as 
  though 
  bone 
  were 
  attached 
  to 
  it. 
  

  

  I 
  cannot 
  speak 
  with 
  any 
  certainty 
  of 
  the 
  affinities 
  of 
  the 
  remark
