  Independently 
  of 
  the 
  question 
  whether 
  the 
  beds 
  c 
  2 
  in 
  this 
  section 
  

   belong 
  to 
  the 
  central 
  ridge 
  or 
  to 
  the 
  flanking 
  rocks, 
  those 
  marked 
  

   d 
  2 
  and 
  d? 
  (the 
  description 
  of 
  which 
  so 
  exactly 
  coincides 
  with 
  the 
  

   Murree 
  group) 
  still 
  appear 
  unconformable 
  to 
  c 
  2 
  , 
  the 
  central 
  limestone 
  ; 
  

   and 
  yet 
  there 
  is 
  only 
  wanting 
  an 
  apparently 
  very 
  probable 
  line 
  of 
  fault 
  

   on 
  each 
  side 
  to 
  make 
  this 
  section 
  resemble 
  a 
  modification 
  of 
  the 
  same 
  

   kind 
  of 
  feature 
  as 
  is 
  represented 
  in 
  our 
  Shah-durrah 
  and 
  Chuttur 
  

   sections 
  (figs. 
  3 
  and 
  4), 
  where 
  the 
  discordance 
  has 
  no 
  similarity 
  to 
  

   unconformity. 
  

  

  It 
  may 
  also 
  be 
  instructive 
  to 
  compare 
  this 
  Dundelee 
  section 
  with 
  

   another 
  in 
  the 
  Pot'war 
  district, 
  some 
  60 
  miles 
  to 
  the 
  S.W., 
  taken 
  

   N.W. 
  and 
  S.E. 
  across 
  Diljubba 
  Mountain, 
  part 
  of 
  a 
  chain 
  of 
  hills 
  

   which 
  runs 
  from 
  the 
  Salt 
  range 
  almost 
  directly 
  towards 
  Dundelee, 
  

   but 
  vanishes 
  before 
  reaching 
  the 
  Jhilam 
  river. 
  The 
  strike 
  of 
  the 
  

   beds 
  is 
  parallel 
  to 
  that 
  of 
  the 
  ridge 
  ; 
  and 
  the 
  section 
  is 
  given 
  from 
  

   memory.

  The 
  Nummulitic 
  limestone 
  in 
  this 
  section 
  has 
  not 
  its 
  full 
  develop- 
  

   ment 
  ; 
  but 
  it 
  shows 
  well 
  the 
  parallelism 
  between 
  this 
  and 
  the 
  suc- 
  

   ceeding 
  strata. 
  The 
  fault 
  shown 
  is 
  the 
  probable 
  extension 
  of 
  a 
  

   long 
  fracture, 
  most 
  strikingly 
  seen 
  further 
  to 
  the 
  west 
  ; 
  and 
  no 
  sign 
  

   of 
  unconformity 
  appears 
  in 
  the 
  section. 
  

  

  Whether 
  the 
  movements 
  connected 
  with 
  the 
  origin 
  of 
  the 
  Hima- 
  

   laya 
  (as 
  out-thrust 
  produced 
  by 
  settlement, 
  &c), 
  to 
  some 
  of 
  which 
  

   Mr. 
  Medlicott 
  ascribes 
  the 
  succession 
  of 
  abnormal 
  junctions 
  of 
  

   the 
  outer 
  Tertiary 
  zones, 
  may 
  have 
  differed 
  in 
  kind, 
  intensity, 
  or 
  in 
  

   number 
  as 
  well 
  as 
  in 
  direction 
  here, 
  is 
  as 
  yet 
  mere 
  matter 
  of 
  specu- 
  

   lation 
  ; 
  but 
  it 
  is 
  at 
  least 
  possible 
  thaj; 
  in 
  the 
  neighbourhood 
  of 
  this 
  

   region 
  the 
  greater 
  variety 
  in 
  the 
  bearings 
  of 
  the 
  vast 
  mountain 
  masses 
  

   may 
  be 
  accompanied 
  by 
  greater 
  complexity 
  in 
  their 
  structure.

  The 
  only 
  attempt 
  to 
  explain 
  the 
  structure 
  of 
  the 
  Tertiary 
  belt 
  

   in 
  this 
  Upper 
  Punjab 
  region 
  with 
  which 
  the 
  writer 
  is 
  acquainted 
  is 
  

   that 
  given 
  in 
  Dr. 
  Verchere's 
  paper 
  before 
  the 
  Asiatic 
  Society, 
  where 
  

   a 
  diagrammatic 
  section 
  occurs 
  at 
  p.
