  felt 
  there, 
  was 
  a 
  distinct 
  one. 
  The 
  reputed 
  feeling 
  of 
  the 
  shock 
  in 
  Iceland 
  and 
  

   Greenland, 
  which 
  has 
  always 
  been 
  regarded 
  with 
  doubt, 
  may 
  safely 
  be 
  rejected. 
  

  

  From 
  this 
  it 
  seems 
  that 
  the 
  most 
  northerly 
  place 
  at 
  which 
  the 
  shock 
  is 
  reported 
  

   to 
  have 
  been 
  felt 
  was 
  Reading, 
  and 
  even 
  this 
  is 
  so 
  doubtful 
  that 
  it 
  may 
  be 
  rejected. 
  

  

  In 
  an 
  easterly 
  direction 
  it 
  is 
  said 
  to 
  have 
  been 
  felt 
  in 
  parts 
  of 
  Switzerland, 
  and 
  

   though 
  the 
  accounts 
  refer 
  mainly 
  to 
  disturbances 
  of 
  the 
  water 
  of 
  the 
  lakes, 
  there 
  

   seems 
  good 
  reason 
  to 
  suppose 
  that 
  the 
  shock 
  was 
  sensible 
  in 
  parts 
  of 
  western 
  

   Switzerland. 
  In 
  Italy 
  it 
  is 
  said 
  to 
  have 
  been 
  felt 
  at 
  Milan 
  and 
  8 
  leagues 
  N. 
  N. 
  W. 
  

   of 
  Turin, 
  but 
  it 
  is 
  not 
  clear 
  whether 
  it 
  was 
  actually 
  felt, 
  or 
  only 
  recognised 
  by 
  

   its 
  effect 
  in 
  setting 
  hanging 
  lamps 
  aswing. 
  It 
  must 
  be 
  remembered 
  too 
  that 
  the 
  

   Italian, 
  besides 
  being 
  gifted 
  with 
  a 
  lively 
  imagination, 
  is, 
  by 
  descent, 
  a 
  skilled 
  

   observer 
  of 
  earthquakes. 
  Even 
  our 
  earthquake 
  of 
  1897 
  is 
  said 
  to 
  have 
  been 
  felt 
  

   in 
  Italy. 
  1 
  In 
  any 
  case 
  Milan 
  and 
  Turin 
  can 
  hardly 
  be 
  looked 
  on 
  as 
  part 
  of 
  the 
  

   main 
  area 
  over 
  which 
  the 
  shock 
  was 
  felt, 
  but 
  as 
  an 
  outlying 
  area 
  like 
  that 
  round 
  

   Ahmadnagar 
  in 
  the 
  case 
  of 
  the 
  1897 
  earthquake. 
  

  

  To 
  the 
  south, 
  it 
  is 
  impossible 
  to 
  define 
  the 
  area 
  over 
  which 
  the 
  shock 
  was 
  felt 
  

   with 
  any 
  degree 
  of 
  accuracy. 
  It 
  was 
  very 
  severely 
  felt 
  in 
  the 
  north-west 
  corner 
  of 
  

   Africa. 
  As 
  far 
  south 
  as 
  Morocco 
  a 
  great 
  number 
  of 
  houses 
  are 
  said 
  to 
  have 
  fallen, 
  

   and 
  one 
  of 
  the 
  hills 
  near 
  by 
  to 
  have 
  been 
  rent 
  in 
  two. 
  This 
  account 
  is 
  almost 
  

   certainly 
  greatly 
  exaggerated, 
  for 
  at 
  Funchal, 
  in 
  Madeira, 
  the 
  shock 
  was 
  only 
  

   smart 
  enough 
  to 
  make 
  windows 
  rattle. 
  

  

  To 
  the 
  west 
  we 
  have 
  the 
  Atlantic 
  ocean, 
  and 
  it 
  is 
  impossible 
  to 
  say 
  how 
  far 
  in 
  

   this 
  direction 
  the 
  shock 
  might 
  or 
  might 
  not 
  have 
  been 
  felt 
  had 
  there 
  been 
  dry 
  land. 
  

  

  The 
  position 
  of 
  the 
  epicentre 
  cannot 
  be 
  fixed 
  with 
  the 
  same 
  accuracy 
  as 
  in 
  the 
  

   case 
  of 
  the 
  1897 
  shock, 
  but 
  the 
  centre 
  from 
  which 
  the 
  great 
  sea-waves 
  started 
  was 
  

   fixed 
  by 
  David 
  Milne 
  at 
  about 
  39 
  N. 
  Lat, 
  ii° 
  W. 
  Long.

  The 
  epicentre 
  of 
  the 
  

   earthquake 
  was 
  not 
  necessarily 
  the 
  same 
  as 
  the 
  centre 
  from 
  which 
  the 
  sea-waves 
  

   started, 
  but 
  the 
  two 
  are 
  not 
  likely 
  to 
  have 
  been 
  widely 
  separated, 
  and 
  there 
  will 
  be 
  

   no 
  material 
  error 
  in 
  assuming 
  the 
  two 
  identical. 
  

  

  Taking 
  the 
  epicentre 
  as 
  situated 
  in 
  the 
  position 
  indicated, 
  we 
  find 
  that 
  Milan 
  is 
  

   distant 
  about 
  1200 
  miles, 
  or 
  practically 
  the 
  distance 
  of 
  Ahmadnagar 
  from 
  the 
  

   epicentre 
  of 
  the 
  1897 
  shock 
  ; 
  and 
  Reading 
  about 
  1000 
  miles, 
  against 
  a 
  distance 
  of 
  

   over 
  900 
  from 
  the 
  epicentre 
  to 
  Bezwada, 
  where 
  the 
  1897 
  shock 
  was 
  distinctly 
  felt. 
  

  

  From 
  this 
  it 
  would 
  seem 
  that 
  the 
  distances 
  from 
  the 
  epicentre 
  at 
  which 
  the 
  two 
  

   shocks 
  were 
  felt 
  were 
  practically 
  the 
  same, 
  but 
  as 
  I 
  have 
  explained 
  above, 
  the 
  

   accounts 
  from 
  Reading 
  and 
  Milan, 
  especially 
  the 
  former, 
  do 
  not 
  appear 
  to 
  be

  At 
  Leghorn 
  a 
  tremor 
  is 
  said 
  to 
  have 
  been 
  felt 
  by 
  some, 
  though 
  not 
  living 
  in 
  upper 
  stories, 
  

   at 
  about 
  12-15. 
  At 
  Catania 
  some 
  people 
  are 
  said 
  to 
  have 
  noticed 
  it, 
  but 
  the 
  accounts 
  are 
  

   vague 
  and 
  uncertain. 
  At 
  Spinea 
  di 
  Mestre 
  (near 
  Venice) 
  an 
  undulating 
  shock 
  of 
  4 
  seconds, 
  

   is 
  said 
  to 
  have 
  been 
  felt 
  in 
  the 
  Observatory 
  at 
  12 
  h. 
  18 
  m. 
  39 
  s. 
  (Boll.

  pp. 
  251, 
  285, 
  289.) 
  The 
  times 
  are 
  mid 
  European, 
  and 
  exactly 
  one 
  hour 
  fast 
  of 
  Greenwich 
  

   mean 
  time. 
  They 
  correspond 
  with 
  that 
  of 
  the 
  first 
  phase, 
  and 
  it 
  is 
  possible 
  that 
  these 
  waves 
  

   of 
  half-second 
  period, 
  were 
  just 
  sensible 
  to 
  very 
  skilled 
  observers, 
  favourably 
  situated.
