  The 
  Anterior 
  Pair 
  of 
  Glands. 
  The 
  epithelium 
  of 
  which 
  

   these 
  glands 
  are 
  composed 
  is 
  made 
  up 
  of 
  cells 
  which 
  have 
  trat 
  little 
  

   secretive 
  function, 
  those 
  cells 
  near 
  the 
  distal 
  ends 
  of 
  the 
  glands 
  being 
  

   somewhat 
  higher 
  than 
  the 
  others 
  (PI. 
  III, 
  Fig. 
  8 
  a.m.gl). 
  Surrounding 
  

   the 
  proximal, 
  fused 
  ends 
  of 
  the 
  glands 
  are 
  nmscle-fibres, 
  irregularly 
  

   arrauged 
  (PI. 
  III, 
  Fig. 
  10 
  a.m.gl). 
  Distad 
  of 
  the 
  point 
  of 
  bifurcation 
  

   of 
  the 
  tubes, 
  the 
  inner 
  most 
  fibres 
  no 
  longer 
  appear. 
  The 
  outer 
  most 
  

   fibres 
  persist, 
  however, 
  and 
  for 
  a 
  short 
  distance 
  form 
  a 
  common 
  

   sheath 
  around 
  the 
  ends 
  of 
  the 
  diverging 
  tubes 
  and 
  hold 
  them 
  together. 
  

   They 
  also 
  Surround 
  each 
  tube 
  after 
  they 
  have 
  ceased 
  to 
  form 
  this 
  

   common 
  sheath 
  for 
  about 
  a 
  quarter 
  of 
  its 
  length. 
  The 
  distal 
  three- 
  

   quarters 
  of 
  the 
  glands 
  have 
  no 
  muscles 
  around 
  them. 
  The 
  entire 
  

   structure 
  is 
  bounded 
  externally 
  by 
  a 
  membrana 
  externa 
  (PI. 
  III, 
  

   Fig. 
  8 
  mem.ex) 
  and 
  internally 
  by 
  a 
  thick 
  membrana 
  interna 
  [mem.in\ 
  

   both 
  of 
  which 
  are 
  structureless. 
  In 
  a 
  longitudinal 
  section 
  of 
  these 
  

   glands 
  their 
  1 
  innen 
  appears 
  bounded 
  by 
  serrated 
  lines 
  which 
  fact 
  is 
  

   due 
  to 
  the 
  projection 
  of 
  the 
  inner 
  ends 
  of 
  their 
  epithelial 
  cells 
  into 
  

   the 
  lumen. 
  

  

  The 
  Posterior 
  Pair 
  of 
  Glands. 
  The 
  fused 
  portion 
  of 
  these 
  

   glands 
  is 
  very 
  short, 
  the 
  two 
  glands 
  joining 
  immediately 
  before 
  

   entering 
  the 
  uterus 
  (PI. 
  III, 
  Fig. 
  8). 
  The 
  free 
  portion 
  of 
  each 
  is 
  

   composed 
  of 
  two 
  distinct 
  divisions, 
  the 
  branched, 
  distal 
  portion 
  in 
  

   which 
  the 
  secretive 
  alone 
  resides, 
  and 
  the 
  unbranched, 
  proximal 
  

   portion 
  which 
  is 
  but 
  the 
  outlet 
  or 
  duct 
  of 
  the 
  other. 
  The 
  epithelium 
  

   of 
  this 
  duct 
  is 
  composed 
  of 
  flat 
  cells 
  which 
  project 
  into 
  its 
  lumen; 
  

   surrounding 
  this 
  are 
  two 
  layers 
  of 
  muscle-fibres. 
  A 
  thick 
  membrana 
  

   interna 
  (PI. 
  III, 
  Fig. 
  8 
  mem.in) 
  lines 
  the 
  lumen 
  and 
  a 
  membrana 
  externa 
  

   [mem.ex) 
  surrounds 
  the 
  muscles 
  on 
  the 
  outside 
  of 
  the 
  ducts. 
  The 
  

   distal 
  portion 
  of 
  the 
  glands 
  is 
  by 
  far 
  the 
  larger 
  part 
  of 
  them. 
  It 
  

   branches 
  very 
  extensively, 
  apparently 
  usually 
  dichotomically 
  (PI. 
  II, 
  

   Fig. 
  2 
  p.m.gl), 
  and 
  fills 
  up 
  a 
  greater 
  part 
  of 
  the 
  entire 
  Space 
  in 
  the 
  

   abdomen 
  which 
  is 
  not 
  occupied 
  by 
  other 
  organs. 
  Its 
  epithelium 
  is 
  

   composed 
  of 
  large 
  cells, 
  0,04 
  mm 
  high, 
  four 
  or 
  five 
  times 
  as 
  large 
  as 
  

   those 
  of 
  the 
  epithelium 
  of 
  the 
  duct. 
  The 
  nucleos 
  is 
  large 
  and 
  

   invariably 
  contains 
  one 
  or 
  two 
  large 
  nucleoli. 
  The 
  protoplasm 
  of 
  

   the 
  cells 
  appears 
  coarsely 
  granulär 
  in 
  stained 
  specimens 
  and 
  often 
  

   contains 
  large 
  vacuoles. 
  The 
  membranae 
  interna 
  and 
  externa 
  are 
  

   present 
  on 
  every 
  part 
  of 
  the 
  glands, 
  but 
  no 
  muscle 
  fibres 
  are 
  on 
  

   the 
  distal, 
  branched 
  portion.
