  Mr. 
  Howard 
  Saunders 
  made 
  some 
  remarks 
  upon 
  the 
  

   distribution 
  of 
  Birds 
  in 
  France, 
  especially 
  with 
  reference 
  to 
  

   some 
  species 
  which 
  passed 
  beyond 
  that 
  country 
  as 
  far 
  as 
  

   Great 
  Britain. 
  He 
  pointed 
  out 
  that 
  a 
  great 
  part 
  of 
  France 
  

   consisted 
  of 
  elevated 
  table-land, 
  and 
  that 
  one 
  main 
  line 
  of 
  

   migration 
  passed 
  along 
  the 
  Rhone 
  Valley 
  and 
  across 
  the 
  

   Langres 
  Plateau 
  on 
  the 
  east 
  ; 
  while 
  on 
  the 
  west 
  side 
  the 
  

   line 
  ran 
  parallel 
  with 
  the 
  coast 
  until 
  it 
  was 
  deflected 
  east- 
  

   ward 
  by 
  the 
  high 
  ground 
  in 
  Britanny 
  and 
  Manche 
  — 
  so 
  that 
  

   the 
  Channel 
  Islands 
  received 
  few 
  visits 
  from 
  rarities. 
  In 
  

   Normandy, 
  however, 
  Tichodroma 
  muraria, 
  Gyps 
  fulvtis, 
  

   Larus 
  melanocephalus, 
  and 
  many 
  other 
  unusual 
  visitants 
  to 
  

   England 
  had 
  occurred 
  several 
  times; 
  Passer 
  petronia, 
  

   Emberiza 
  cia, 
  yEgithalus 
  pendulinus, 
  and 
  Vultur 
  monachus 
  

   had 
  also 
  been 
  obtained, 
  while 
  Aquila 
  pennata 
  had 
  even 
  bred 
  

   there. 
  On 
  the 
  other 
  hand, 
  Picus 
  martins, 
  said 
  — 
  falsely 
  as 
  

   he 
  believed 
  — 
  to 
  have 
  occurred 
  in 
  England, 
  had 
  never 
  

   been 
  met 
  with 
  in 
  Normandy. 
  He 
  further 
  remarked 
  upon
