  The 
  expense 
  of 
  these 
  experiments 
  has 
  been 
  defrayed 
  by 
  a 
  vote 
  of 
  

   the 
  Governnient-Grant 
  Fund. 
  

  

  The 
  experiments 
  on 
  the 
  vibration 
  of 
  pendulums, 
  which 
  were 
  conducted 
  

   by 
  Capt. 
  Heaviside, 
  R.E., 
  in 
  connexion 
  with 
  the 
  Great 
  Trigonometrical 
  

   Survey 
  of 
  India, 
  as 
  mentioned 
  in 
  the 
  last 
  Report, 
  were 
  completed 
  at 
  the 
  

   end 
  of 
  May. 
  The 
  apparatus 
  employed 
  in 
  the 
  experiments, 
  with 
  the 
  ex- 
  

   ception 
  of 
  the 
  Russian 
  pendulums 
  and 
  their 
  accessories, 
  was, 
  at 
  the 
  re- 
  

   quest 
  of 
  Prof. 
  G. 
  G. 
  Stokes, 
  F.R.S., 
  received 
  at 
  Kew 
  for 
  storage. 
  

  

  The 
  apparatus 
  for 
  testing 
  Sextants, 
  which 
  had 
  been 
  temporarily 
  re- 
  

   moved 
  in 
  1873 
  to 
  afford 
  space 
  for 
  swinging 
  the 
  Russian 
  pendulums, 
  has 
  

   now 
  been 
  restored. 
  The 
  entire 
  cost 
  of 
  this 
  restoration 
  and 
  all 
  other 
  

   expenses 
  connected 
  with 
  these 
  pendulum 
  experiments 
  have 
  been 
  defrayed 
  

   by 
  the 
  India 
  Office. 
  

  

  The 
  collimators 
  of 
  the 
  Sextant 
  Testing-apparatus 
  have 
  been 
  arranged 
  

   so 
  as 
  to 
  be 
  illuminated 
  by 
  gas-jets. 
  

  

  Waxed 
  paper 
  for 
  photographic 
  purposes 
  has 
  been 
  supplied 
  to 
  the 
  

   Meteorological 
  Office 
  (3 
  reams), 
  the 
  India 
  Office 
  (1 
  ream), 
  the 
  Magnetic 
  

   Observatory, 
  Toronto 
  (4 
  reams), 
  the 
  Central 
  Observatory, 
  St. 
  Peters- 
  

   burg 
  (1 
  ream), 
  the 
  Hohe 
  Warte, 
  Vienna 
  (| 
  ream), 
  the 
  Observatory 
  of 
  

   Don 
  Luiz, 
  Lisbon 
  (| 
  ream). 
  

  

  It 
  has 
  been 
  found 
  necessary 
  to 
  make 
  a 
  change 
  in 
  the 
  arrangements 
  

   for 
  obtaining 
  waxed 
  paper. 
  For 
  many 
  years, 
  through 
  the 
  kindness 
  of 
  a 
  

   firm, 
  the 
  paper 
  waxed 
  at 
  Kew 
  has 
  been 
  hot-pressed 
  at 
  a 
  nominal 
  charge, 
  

   but 
  it 
  was 
  not 
  found 
  possible 
  to 
  continue 
  this 
  arrangement 
  for 
  an 
  inde- 
  

   finite 
  period. 
  Waxed 
  paper 
  has 
  now 
  to 
  be 
  purchased, 
  ready-made, 
  at 
  a 
  

   considerable 
  increase 
  of 
  cost, 
  and 
  the 
  rate 
  at 
  which 
  it 
  is 
  supplied 
  to 
  

   observatories 
  has 
  been 
  consequently 
  proportionately 
  increased. 
  

  

  Mr. 
  M'Clatchie 
  and 
  Mr. 
  Beazeley, 
  gentlemen 
  holding 
  appointments 
  

   in 
  the 
  Chinese 
  Customs 
  Departments, 
  and 
  Mr. 
  Steventon, 
  appointed 
  

   Assistant 
  to 
  the 
  Observatory 
  at 
  Mauritius, 
  have 
  received 
  instruction 
  in 
  

   the 
  manipulation 
  and 
  methods 
  of 
  testing 
  both 
  Meteorological 
  and 
  Mag- 
  

   netical 
  instruments, 
  and 
  the 
  management 
  of 
  the 
  photography 
  of 
  the 
  self- 
  

   recording 
  apparatus. 
  

  

  In 
  the 
  month 
  of 
  September 
  the 
  Superintendent 
  was 
  informed 
  by 
  the 
  

   President 
  of 
  the 
  Royal 
  Society 
  that 
  that 
  body 
  was 
  prepared 
  to 
  remove 
  

   the 
  instruments 
  belonging 
  to 
  it, 
  which 
  had 
  been 
  deposited 
  at 
  Kew 
  for 
  

   storage 
  in 
  Sept. 
  1851. 
  Accordingly, 
  on 
  the 
  25th 
  of 
  September, 
  they 
  

   were 
  handed 
  over 
  to 
  Mr. 
  Ladd, 
  Optician, 
  who 
  had 
  been 
  commissioned 
  

   by 
  the 
  Council 
  to 
  receive 
  them.
