  There 
  are 
  about 
  15-20

   being

  The 
  following 
  section 
  was 
  brought 
  to 
  my 
  notice 
  by 
  the 
  

   kindness 
  of 
  the 
  Rev. 
  H. 
  H. 
  Winwood, 
  F.G.S., 
  with 
  whom 
  I 
  visited 
  

   the 
  spot. 
  He 
  also 
  made 
  some 
  notes 
  of 
  this 
  section 
  when 
  the 
  line 
  

   was 
  first 
  opened 
  and 
  I 
  refer 
  the 
  reader 
  to 
  them

  The 
  most 
  remarkable 
  feature 
  in 
  the 
  Section 
  is 
  probably 
  a 
  point 
  

   now 
  noticed 
  for 
  the 
  first 
  time, 
  namely, 
  that 
  one 
  single 
  block 
  of 
  

   stone, 
  only 
  1 
  foot 
  7 
  inches 
  thick, 
  contains 
  portions 
  of 
  three 
  different 
  

   zones, 
  and 
  exhibits 
  three 
  different 
  bands 
  of 
  matrix 
  firmly 
  cemented 
  

   together 
  f 
  . 
  

  

  Brown, 
  coarse, 
  oolitic 
  stone, 
  

   5 
  inches. 
  

  

  Brown, 
  oolitic 
  stone, 
  not 
  so 
  

   coarse 
  in 
  texture, 
  4 
  inches. 
  

  

  Bluish-grey 
  stone 
  with 
  a 
  

   soapy 
  feel, 
  non-oolitic, 
  

   10 
  inches. 
  

  

  Striatuhm-beds 
  : 
  Jurense-zone. 
  

  

  Commune-zone. 
  

  

  Falciferum-zone. 
  

  

  The 
  attenuation 
  of 
  the 
  Commune-zone 
  is 
  very 
  great, 
  and 
  not 
  

   improbably 
  careful 
  research 
  would 
  show 
  some 
  admixture 
  of 
  its 
  species 
  

   with 
  those 
  of 
  the 
  Striatulum-beds 
  above. 
  The 
  other 
  two 
  zones 
  ex- 
  

   tend, 
  one 
  above 
  — 
  Jurense-zone, 
  Dispansum-oeb\s 
  — 
  the 
  other 
  below 
  — 
  

   Falciferum-zone, 
  Blue 
  Clay. 
  

  

  Another 
  point 
  to 
  be 
  noticed 
  in 
  this 
  Section 
  is 
  that 
  the 
  Yellow 
  

   Sands 
  have 
  ascended 
  one 
  stage 
  higher. 
  They 
  do 
  not, 
  as 
  at 
  Sodbury, 
  

   envelop 
  the 
  strata 
  known 
  as 
  the 
  Striatulum-beda, 
  but 
  they 
  begin 
  

   above 
  them. 
  Consequently 
  the 
  next 
  series 
  (that 
  of 
  the 
  Dispansum-

  t 
  I 
  had, 
  not 
  long 
  previously, 
  discovered 
  a 
  similar, 
  but 
  perhaps 
  more 
  extra- 
  

   ordinary, 
  instance 
  of 
  the 
  same 
  feature. 
  At 
  a 
  small 
  quarry 
  on 
  Lodge 
  Hill, 
  just 
  

   south 
  of 
  Castle 
  Ca,ry, 
  Somerset, 
  the 
  lower 
  part 
  of 
  the 
  ParJcinsoni-zone 
  is 
  ce- 
  

   mented 
  firmly 
  to 
  Sandstone 
  of 
  the 
  Yeovil 
  Sands 
  (Opalinum-zone) 
  ; 
  and 
  the 
  mass 
  

   comes 
  from 
  the 
  quarry 
  as 
  one 
  piece 
  of 
  stone 
  exhibiting 
  two 
  bands 
  of 
  very 
  

   different 
  matrix, 
  thus 
  : 
  — 
  

  

  Brownish 
  oolitic 
  limestone, 
  

   3 
  inches. 
  

  

  Bluish-grey, 
  hard, 
  gritty 
  

   sandstone, 
  8 
  inches. 
  

  

  Parkinsoni-zone. 
  

  

  I 
  Opalinum-zone. 
  

  

  This 
  is 
  the 
  more 
  remarkable 
  when 
  we 
  consider 
  that 
  the 
  time 
  of 
  formation 
  of 
  

   the 
  Murchisonce- 
  to 
  the 
  Hzimphriesianum-zoneB 
  inclusive 
  had 
  elapsed 
  between 
  

   the 
  deposition 
  of 
  the 
  upper 
  and 
  lower 
  of 
  these 
  two 
  bands.
