  S. 
  C. 
  Hastings 
  read 
  a 
  paper 
  in 
  reference 
  to 
  the 
  late 
  alleged 
  man- 
  

   ifestations 
  in 
  Oakland. 
  

  

  Dr. 
  Fourgeaud 
  read 
  a 
  paper, 
  a 
  continuation 
  of 
  previous 
  papers, 
  

   " 
  On 
  Evolution." 
  

  

  The 
  President 
  called 
  the 
  attention 
  of 
  the 
  members 
  to 
  some 
  phe- 
  

   nomena 
  which 
  he 
  observed 
  at 
  the 
  Naval 
  Observatory, 
  while 
  looking 
  

   at 
  an 
  artificial 
  transit 
  of 
  Venus. 
  At 
  the 
  time 
  of 
  the 
  earlier 
  observa- 
  

   tions 
  of 
  this 
  planet, 
  there 
  was 
  a 
  doubt 
  as 
  to 
  a 
  phenomenon 
  which 
  

   showed 
  an 
  apparent 
  adherence 
  of 
  the 
  limb 
  of 
  Venus 
  to 
  the 
  edge 
  of 
  

   the 
  sun 
  in 
  the 
  internal 
  contact. 
  This 
  was 
  known 
  as 
  the 
  " 
  black 
  

   drop," 
  when 
  Venus 
  showed 
  an 
  irregular 
  spherical 
  condition. 
  As 
  

   soon 
  as 
  I 
  saw 
  the 
  artificial 
  Venus, 
  I 
  recognized 
  the 
  cause 
  of 
  this 
  

   thing. 
  We 
  see 
  it 
  every 
  day 
  in 
  the 
  work 
  of 
  the 
  Coast 
  Survey. 
  It 
  

   is 
  simply 
  the 
  undulation 
  of 
  the 
  atmosphere 
  when 
  it 
  is 
  surcharged
