  ANALYSIS 
  OF 
  THE 
  MAMMALIAN 
  AND 
  AVIAN 
  FAUNA. 
  

  

  Of 
  the 
  360-70 
  species 
  included 
  in 
  various 
  Lists 
  of 
  British 
  birds, 
  

   255 
  have 
  a 
  place 
  in 
  our 
  volumes, 
  and 
  these 
  are 
  classed 
  as 
  under 
  :

  specific 
  value.

  Formerly 
  nested,

  no

  so.

  These 
  numbers 
  can 
  only 
  be 
  taken 
  as 
  approximate. 
  Owing 
  to 
  

   preservation 
  or 
  persecutions 
  some 
  species 
  are 
  still 
  increasing 
  or 
  

   decreasing, 
  according 
  to 
  whether 
  they 
  come 
  under 
  one 
  head 
  or 
  the 
  

   other. 
  Besides, 
  we 
  have 
  reasons 
  for 
  believing 
  that 
  the 
  Moray 
  Firth 
  

   is 
  the 
  farthest 
  northern 
  winter 
  range 
  of 
  certain 
  species, 
  though 
  

   further 
  observation 
  and 
  time 
  alone 
  can 
  actually 
  prove 
  this, 
  and 
  such 
  

   an 
  analysis 
  as 
  this 
  must 
  be 
  tentative 
  in 
  many 
  details.
