  When 
  the 
  amplitude 
  was 
  less 
  than 
  i 
  millimeter 
  as 
  a 
  maximum, 
  

   it 
  has 
  not 
  been 
  given. 
  

  

  October 
  i6. 
  A 
  record 
  of 
  a 
  microseism 
  which 
  appears 
  to 
  have 
  

   been 
  transmitted 
  around 
  the 
  globe. 
  It 
  was 
  reported 
  by 
  many 
  of 
  the 
  

   foreign 
  stations. 
  Judging 
  from 
  the 
  local 
  tracing', 
  the 
  focus 
  was 
  

   approximately 
  5000 
  miles 
  distant 
  in 
  a 
  direction 
  south 
  of 
  west, 
  

   somewhere 
  between 
  the 
  Hawaiian 
  islands 
  and 
  the 
  coast 
  of 
  ^Mexico. 
  

   It 
  was 
  undoubtedly 
  submarine. 
  Slight 
  shocks 
  were 
  reported 
  from 
  

   California 
  on 
  the 
  same 
  date. 
  

  

  October 
  20. 
  Slight 
  wave 
  motion 
  extending 
  over 
  a 
  period 
  of 
  

   two 
  hours. 
  Also 
  reported 
  by 
  the 
  stations 
  on 
  the 
  Isle 
  of 
  Wight 
  

   and 
  at 
  Laibach, 
  Austria. 
  The 
  focus 
  seems 
  to 
  have 
  been 
  in 
  cen- 
  

   tral 
  Asia, 
  probably 
  in 
  Bokhara 
  where 
  several 
  towns 
  were 
  badly 
  

   shaken 
  and 
  damaged. 
  

  

  December 
  30. 
  A 
  severe 
  disturbance, 
  perhaps 
  from 
  the 
  same 
  

   zone 
  as 
  the 
  earthcpiake 
  of 
  October 
  16. 
  The 
  origin 
  is 
  estimated
