  Beddard 
  on 
  the 
  

  

  The 
  arrangement 
  of 
  the 
  deep 
  flexor 
  tendons 
  is 
  illustrated 
  

   in 
  the 
  accompanying 
  drawing 
  (fig. 
  2, 
  b). 
  It 
  will' 
  be 
  observed 
  

   that 
  each 
  tendon 
  splits 
  into 
  three, 
  apart 
  from 
  the 
  special 
  

   branch 
  to 
  digit 
  1 
  given 
  off 
  from 
  the 
  flexor 
  hallucis.

  III. 
  Visceral 
  Anatomy. 
  

  

  I 
  do 
  not 
  think 
  that 
  it 
  is 
  necessary 
  to 
  give 
  a 
  detailed 
  

   account 
  of 
  the 
  alimentary 
  tract 
  of 
  this 
  bird. 
  In 
  the 
  first 
  

   place^, 
  the 
  viscera 
  were 
  not 
  in 
  a 
  very 
  good 
  condition 
  for 
  

   furnishing 
  a 
  careful 
  report 
  ; 
  they 
  were 
  softened 
  by 
  the 
  

   action 
  of 
  the 
  weak 
  spirit 
  in 
  which 
  they 
  bad 
  been 
  preserved, 
  

   and 
  were 
  at 
  the 
  same 
  time 
  much 
  adherent. 
  In 
  the 
  second 
  

   place, 
  the 
  main 
  characteristics 
  of 
  the 
  viscera 
  are 
  precisely 
  as 
  

   in 
  Podica; 
  in 
  both 
  genera 
  the 
  right 
  liver-lobe 
  is 
  larger 
  

   than 
  the 
  left, 
  and 
  there 
  are 
  a 
  pair 
  of 
  moderately 
  long 
  cseca 
  

   present. 
  

  

  In 
  the 
  syrinx 
  the 
  bronchidesmus 
  is 
  incomplete, 
  there 
  being 
  

   a 
  gap 
  of 
  about 
  2 
  mm. 
  in 
  length 
  between 
  the 
  diverging 
  

   bronchi. 
  There 
  are 
  ten 
  to 
  twelve 
  bronchial 
  semirings 
  on 
  

   each 
  side. 
  The 
  last 
  three 
  or 
  four 
  tracheal 
  rings 
  are 
  partly 
  

   fused 
  (incompletely 
  in 
  front) 
  to 
  form 
  a 
  box. 
  The 
  single 
  

   pair 
  of 
  intrinsic 
  muscles 
  is 
  present.
