  During 
  our 
  southern 
  cruise 
  the 
  sounding-lead 
  brought* 
  up 
  five 
  abso- 
  

   lutely 
  distinct 
  kinds 
  of 
  sea-bottom, 
  without 
  taking 
  into 
  account 
  the 
  rock 
  

   and 
  detritus 
  of 
  shallow 
  soundings 
  in 
  the 
  neighbourhood 
  of 
  land. 
  Our 
  

   first 
  two 
  soundings 
  in 
  98 
  and 
  150 
  fathoms, 
  on 
  the 
  17th 
  and 
  18th 
  of 
  

   December, 
  were 
  in 
  the 
  region 
  of 
  the 
  Agulhas 
  current. 
  These 
  soundings 
  

   would 
  have 
  been 
  naturally 
  logged 
  " 
  greenish 
  sand 
  but 
  on 
  examining 
  the 
  

   sandy 
  particles 
  with 
  the 
  microscope, 
  they 
  were 
  found 
  to 
  consist 
  almost 
  

   without 
  exception 
  of 
  the 
  casts 
  of 
  Eoraminifera 
  in 
  one 
  of 
  the 
  complex 
  

   silicates 
  of 
  alumina, 
  iron, 
  and 
  potash, 
  probably 
  some 
  form 
  of 
  glauconite.
