  the 
  wall, 
  wliicli 
  is 
  t\Yenty-four 
  feet 
  distant 
  and 
  on 
  the 
  line 
  of 
  the 
  

   street, 
  they 
  have 
  been 
  covered 
  with 
  debris 
  to 
  bring 
  the 
  surface 
  of 
  

   the 
  ground 
  to 
  the 
  level 
  of 
  the 
  top 
  of 
  the 
  wall. 
  I 
  think 
  it 
  is 
  safe 
  to 
  

   say 
  that 
  the 
  position 
  of 
  M. 
  Chappe's 
  instruments 
  has 
  been 
  recovered 
  

   within 
  a 
  space 
  of 
  twenty 
  feet 
  square. 
  This 
  has 
  been 
  referred 
  to 
  

   the 
  southeast 
  corner 
  of 
  the 
  present 
  church, 
  which 
  was 
  included 
  in 
  

   the 
  scheme 
  of 
  triangulation 
  to 
  connect 
  it 
  with 
  the 
  astronomical 
  sta- 
  

   tion 
  near 
  the 
  present 
  landing. 
  The 
  "Mission 
  Viejo" 
  and 
  the 
  cem- 
  

   etery 
  "were 
  also 
  included 
  in 
  the 
  scheme. 
  

  

  The 
  geographical 
  position 
  of 
  the 
  astronomical 
  station 
  had 
  been 
  

   been 
  determined 
  under 
  my 
  directions 
  by 
  Mr. 
  W. 
  Eimbeck, 
  of 
  the 
  

   U. 
  S. 
  Coast 
  Survey, 
  about 
  a 
  fortnight 
  before 
  my 
  arrival. 
  The 
  

   longitude 
  is 
  determined 
  by 
  the 
  transmission 
  of 
  twenty-four 
  chrono- 
  

   meters 
  from 
  and 
  to 
  San 
  Diego, 
  which 
  had 
  been 
  connected 
  with 
  San 
  

   Francisco 
  by 
  telegraph. 
  The 
  latitude 
  was 
  determined 
  by 
  the 
  zenith 
  

   telescope 
  method 
  of 
  the 
  Coast 
  Survey. 
  

  

  Thus 
  after 
  an 
  interval 
  of 
  one 
  hundred 
  and 
  four 
  years, 
  we 
  have 
  

   been 
  able 
  to 
  make 
  available 
  the 
  observations 
  of 
  one 
  who 
  gave 
  his 
  

   life 
  a 
  sacrifice 
  to 
  scientific 
  pursuits. 
  

  

  Of 
  the 
  position 
  of 
  Velasquez's 
  station 
  for 
  observing 
  the 
  same 
  

   phenomenon 
  at 
  the 
  "village 
  of 
  Santa 
  Anna, 
  a 
  position 
  which 
  is 
  not 
  

   placed 
  on 
  the 
  charts," 
  I 
  could 
  gather 
  no 
  clew 
  whatever. 
  In 
  en- 
  

   deavoring 
  to 
  reconcile 
  the 
  two 
  disjointed 
  remarks 
  of 
  Cassini 
  (pp. 
  43 
  

   and 
  112), 
  it 
  would 
  appear 
  to 
  have 
  been 
  at 
  some 
  rancho 
  on 
  the 
  

   shores 
  of 
  Ceralvo 
  Bay, 
  about 
  thirty 
  leagues 
  northward 
  and 
  eastward 
  

   of 
  San 
  Jose 
  del 
  Cabo, 
  following 
  the 
  coast 
  line. 
  

  

  A 
  search 
  of 
  the 
  archives 
  at 
  Madrid 
  last 
  season 
  had 
  failed 
  to 
  elicit 
  

   any 
  knowledge 
  of 
  Velasquez's 
  records 
  or 
  report. 
  

  

  Mr. 
  Stearns 
  referred 
  to 
  the 
  valuable 
  and 
  acceptable 
  present 
  of 
  

   Mr. 
  Hickox 
  as 
  an 
  important 
  acquisition 
  to 
  the 
  Academy's 
  library, 
  

   and 
  on 
  motion, 
  a 
  special 
  vote 
  of 
  thanks 
  was 
  unanimously 
  tendered 
  to 
  

   that 
  gentleman 
  for 
  this 
  very 
  handsome 
  gift. 
  

  

  Mr. 
  Gutzkow 
  read 
  the 
  following, 
  describing 
  a 
  new 
  process 
  for 
  

   the 
  extraction 
  of 
  Boracic 
  acid, 
  and 
  illustrating 
  by 
  a 
  working 
  model 
  

   the 
  method 
  pursued 
  by 
  him.
