  Discussion. 
  

  

  The 
  President 
  expressed 
  the 
  Society's 
  obligation 
  to 
  Mr. 
  Baron 
  ; 
  

   a 
  certain 
  amount 
  was 
  known 
  about 
  the 
  geology 
  of 
  the 
  island, 
  but 
  the 
  

   information 
  was 
  chiefly 
  contributed 
  by 
  the 
  French. 
  He 
  would 
  be 
  

   glad 
  to 
  hear 
  if 
  the 
  crystalline 
  rocks 
  of 
  Madagascar 
  resembled 
  

   those 
  of 
  the 
  Seychelles. 
  Might 
  the 
  beds 
  at 
  the 
  base 
  of 
  the 
  sand- 
  

   stone 
  be 
  representatives 
  of 
  the 
  great 
  Karoo 
  formation 
  ? 
  M. 
  Fischer 
  

   had 
  described 
  Jurassic 
  fossils 
  some 
  years 
  ago. 
  Were 
  any 
  of 
  the 
  

   Lower 
  Cretaceous 
  fossils 
  allied 
  to 
  the 
  Neocomian 
  fauna 
  described 
  

   by 
  Krauss 
  and 
  Tate 
  from 
  S. 
  Africa? 
  It 
  was 
  possible 
  that 
  Mr. 
  

   "Wallace 
  had 
  exaggerated 
  the 
  similarity 
  between 
  the 
  Malagasy 
  and 
  

   African 
  faunas 
  ; 
  the 
  reptiles 
  especially 
  were 
  very 
  different. 
  He 
  

   inquired 
  whether 
  the 
  flora 
  showed 
  any 
  connexion 
  with 
  that 
  of 
  the 
  

   other 
  side 
  of 
  the 
  Indian 
  Ocean. 
  

  

  Dr. 
  Geikie 
  gave 
  expression 
  to 
  the 
  pleasure 
  with 
  which 
  the 
  

   Society 
  had 
  listened 
  to 
  Mr. 
  Baron's 
  paper, 
  and 
  hoped 
  the 
  Author 
  would 
  

   return 
  encouraged 
  to 
  renew 
  the 
  researches 
  which 
  he 
  had 
  carried 
  on 
  

   with 
  such 
  industry 
  and 
  success 
  in 
  his 
  distant 
  home. 
  

  

  Mr. 
  H. 
  B. 
  Woodward 
  commented 
  on 
  the 
  interesting 
  discovery 
  of 
  

   so 
  many 
  species 
  of 
  common 
  British 
  fossils 
  in 
  the 
  island 
  ; 
  among 
  

   these, 
  Ammonites 
  macrocephalus 
  had 
  been 
  recorded 
  also 
  from 
  India 
  

   and 
  Western 
  Australia. 
  

  

  Mr. 
  Toplet 
  referred 
  to 
  the 
  intrusive 
  bosses 
  of 
  granite, 
  one 
  of 
  

   which 
  had 
  its 
  porphyritic 
  crystals 
  arranged 
  roughly 
  parallel 
  with 
  

   the 
  line 
  of 
  junction 
  between 
  the 
  granite 
  and 
  the 
  crystalline 
  schists 
  

   near 
  the 
  contact. 
  The 
  shape 
  of 
  the 
  cones 
  also 
  was 
  of 
  great 
  interest. 
  

   He 
  compared 
  the 
  structure 
  of 
  the 
  volcanic 
  district 
  with 
  that 
  of 
  

   Kilima-njaro. 
  

  

  The 
  Rev. 
  E. 
  Baron, 
  in 
  reply, 
  stated 
  that 
  the 
  fossils 
  described 
  by 
  

   Fischer 
  were 
  those 
  discovered 
  by 
  Grandidier 
  ; 
  they 
  were 
  included 
  

   in 
  the 
  lists 
  appended 
  to 
  the 
  present 
  paper. 
  The 
  sandstone 
  was 
  often 
  

   red 
  and 
  apparently 
  unfossiliferous 
  ; 
  the 
  recent 
  fauna, 
  as 
  a 
  whole, 
  

   seemed 
  largely 
  allied 
  to 
  the 
  African 
  one 
  ; 
  and 
  the 
  flora 
  is 
  distinctly 
  

   allied 
  to 
  that 
  of 
  Africa, 
  as 
  he 
  had 
  shown 
  in 
  a 
  paper 
  read 
  before 
  

   the 
  Linuean 
  Society 
  : 
  there 
  was 
  also 
  some 
  connexion 
  with 
  the 
  

   flora 
  of 
  India, 
  the 
  evidence 
  for 
  which 
  was 
  chiefly 
  found 
  near 
  the 
  

   east 
  coast 
  of 
  the 
  island. 
  He 
  did 
  not 
  think 
  there 
  was 
  any 
  con- 
  

   nexion 
  between 
  the 
  floras 
  of 
  Madagascar 
  and 
  Australia.
