  at 
  4000 
  miles 
  from 
  Albany. 
  The 
  shocks 
  appear 
  to 
  have 
  left 
  no 
  

   trace 
  on 
  land 
  and 
  can 
  be 
  assigned 
  without 
  much 
  doubt 
  to 
  a 
  sub- 
  

   marine 
  source. 
  

  

  February 
  i. 
  Slight 
  movements 
  of 
  unknown 
  origin. 
  

  

  March 
  26. 
  A 
  record 
  of 
  the 
  earthquake 
  that 
  occurred 
  in 
  the 
  

   State 
  of 
  Guerrero, 
  - 
  Alexico, 
  and 
  is 
  reported 
  to 
  have 
  destroyed 
  

   Chilapa, 
  a 
  town 
  115 
  miles 
  south 
  of 
  the 
  City 
  of 
  Mexico. 
  Two 
  

   distinct 
  series 
  of 
  vibrations 
  were 
  registered, 
  beginning 
  nearly 
  five 
  

   hours 
  apart. 
  The 
  first 
  was 
  the 
  more 
  violent 
  and 
  represented 
  the 
  

   distinctive, 
  shocks. 
  The 
  records 
  by 
  both 
  pendulums 
  were 
  of 
  the 
  

   same 
  degree 
  of 
  magnitude. 
  The 
  indicated 
  distance 
  of 
  the 
  origin, 
  

   according 
  to 
  the 
  Omori 
  formula, 
  was 
  3000 
  miles, 
  which 
  is 
  about 
  

   the 
  actual 
  distance. 
  

  

  May 
  15. 
  Small 
  vibrations, 
  lasting- 
  about 
  40 
  minutes. 
  No 
  in- 
  

   dication 
  of 
  origin 
  shown 
  by 
  the 
  records. 
  The 
  shocks 
  were 
  regis- 
  

   tered 
  also 
  by 
  the 
  station 
  operated 
  by 
  the 
  Weather 
  Bureau 
  near 
  

   Washington 
  and 
  according 
  tO' 
  its 
  reports 
  were 
  probably 
  from 
  a 
  

   source 
  in 
  Central 
  America 
  or 
  in 
  the 
  adjacent 
  reg'ion 
  of 
  the 
  Pacific.

  An 
  indefinite 
  microseism 
  somewhat 
  similar 
  in 
  char- 
  

   acter 
  to 
  the

  off 
  the 
  coast

  MINERALOGY 
  

  

  In 
  the 
  section 
  of 
  mineralogy, 
  the 
  work 
  of 
  research 
  has 
  pro- 
  

   gressed 
  along 
  the 
  lines 
  of 
  a 
  monograph 
  on 
  the 
  crystal 
  forms 
  of 
  

   New 
  York 
  calcite, 
  now 
  nearing 
  completion. 
  A 
  mass 
  of 
  excellent 
  

   material 
  from 
  a 
  number 
  of 
  widely 
  distributed 
  localities 
  was 
  avail- 
  

   able 
  for 
  this 
  study, 
  which 
  has 
  already 
  yielded 
  eight 
  forms 
  new 
  to 
  

   the 
  species. 
  

  

  A 
  notable 
  collection 
  of 
  minerals 
  from 
  the 
  celebrated 
  localities 
  of 
  

   northern 
  New 
  York 
  and 
  Canada 
  has 
  been 
  acquired 
  by

  includ- 
  

   ing 
  many
