  painful, 
  but 
  vers- 
  rapidly 
  become 
  painless. 
  The 
  animal 
  appears 
  

   depressed, 
  loss 
  of 
  appetite 
  and 
  rumination 
  ceases. 
  There 
  is 
  

   also 
  lameness, 
  stiffness 
  and 
  a 
  dragging 
  of 
  one 
  limb. 
  Sometimes 
  

   there 
  i^ 
  groaning 
  and 
  colicky 
  pains. 
  At 
  a 
  post-mortem, 
  when 
  the 
  

   skin 
  is 
  cut 
  over 
  the 
  affected 
  quarter, 
  a 
  blood-stained, 
  frothy 
  liquid 
  

   escapes. 
  The 
  connective 
  tissue 
  contains 
  gas. 
  The 
  muscles 
  under- 
  

   neath 
  the 
  tumor 
  are 
  of 
  a 
  dirty 
  brown 
  or 
  even 
  bla^jk 
  color. 
  The 
  

   muscles 
  of 
  the 
  unaffected 
  quartei-s 
  are 
  practically 
  normal 
  in 
  appear-

  In 
  the 
  abdominal 
  cavity 
  there 
  will 
  be 
  found 
  bloody 
  fluid. 
  

  

  The 
  spleen, 
  which 
  is 
  on 
  the 
  left 
  side, 
  attached 
  to 
  the 
  iiimen 
  or 
  

   paunch, 
  is 
  not 
  enlarged 
  as 
  in 
  anthrax. 
  The 
  main 
  differences 
  between 
  

   anthrax 
  and 
  black 
  quarter 
  may 
  be 
  summarized 
  as 
  follow: 
  

  

  1. 
  Black 
  quarter 
  is 
  characterized 
  by 
  crackling, 
  gas-containing 
  

   tumors 
  beneath 
  the 
  skin. 
  These 
  never 
  occur 
  in 
  anthrax. 
  

  

  2. 
  By 
  the 
  above-described 
  changes 
  in 
  the 
  muscles, 
  w^hich 
  always 
  

   contain 
  gas, 
  and 
  by 
  the 
  normal 
  condition 
  of 
  the 
  Ijlood 
  and 
  spleen. 
  

   The 
  blood 
  coagulates 
  freely, 
  while 
  in 
  anthrax 
  it 
  does 
  not. 
  

  

  3. 
  The 
  bacillus 
  of 
  black 
  quarter 
  differs 
  from 
  that 
  of 
  anthrax. 
  

   The 
  bacillus 
  of 
  black 
  quarter 
  is 
  anaerobic, 
  that 
  of 
  anthrax 
  aerolic. 
  

  

  ■i. 
  Black 
  quarter 
  usually 
  affects 
  only 
  young 
  cattle; 
  anthrax 
  

   attacks 
  all 
  genera 
  of 
  animals 
  at 
  any 
  age. 
  

  

  There 
  is 
  no 
  medicinal 
  treatment 
  which 
  can 
  be 
  relied 
  upon; 
  pro- 
  

   phylaxis 
  is 
  the 
  best 
  treatment. 
  It 
  is 
  also 
  highly 
  important 
  that 
  all 
  

   manure, 
  i)edding, 
  carcasses 
  or 
  any 
  secretion 
  from 
  a 
  deceased 
  animal 
  

   should 
  he 
  burned 
  or 
  buried 
  deeply 
  and 
  covered 
  with 
  quick-lime; 
  

   if 
  this 
  is 
  not 
  done, 
  the 
  disease 
  is 
  liable 
  to 
  appear 
  for 
  several 
  years 
  

   on 
  the 
  infected 
  farm 
  or 
  in 
  a 
  particular 
  locality. 
  This 
  is 
  due 
  to 
  

   the 
  spores 
  living 
  for 
  years.

  One 
  case 
  of 
  this 
  disease 
  has 
  been 
  reported. 
  Prior 
  to 
  my 
  visit 
  to 
  

   a 
  certain 
  farm, 
  four 
  milch 
  cows 
  had 
  died 
  from 
  tlie 
  disease 
  and 
  two 
  

   others 
  were 
  affected 
  at 
  the 
  time 
  of 
  my 
  visit. 
  I 
  instructed 
  the 
  

   owner 
  as 
  to 
  the 
  cause, 
  prescribed 
  treatment 
  and 
  asked 
  him 
  to 
  re-
