  Such 
  differences 
  are 
  often 
  far 
  exceeded 
  by 
  dif- 
  

   ferent 
  specimens 
  of 
  one 
  stock 
  of 
  genn 
  seeded 
  on 
  different

   There 
  is 
  no

  difference 
  in

  and 
  the 
  via- 
  

   bility 
  in 
  light, 
  dryness, 
  cold, 
  and 
  putrefaction. 
  The 
  tendency 
  is 
  in 
  

   all 
  cases 
  to 
  colonize 
  the 
  lymph-plexus 
  or 
  glands 
  and 
  to 
  develop 
  the 
  

   specific 
  lesions, 
  with 
  slight 
  variation 
  in 
  detail. 
  The 
  slow 
  develop- 
  

   ment 
  of 
  the 
  lesions

  both 
  forms 
  of 
  bacilli 
  and 
  their 
  histo- 
  

   logical 
  similarity

  The 
  prevalence 
  ol 
  

   tuberculosis 
  in 
  man 
  and 
  ox 
  in 
  the 
  same 
  country 
  and 
  district 
  is 
  so 
  

   frequent 
  tlmt 
  it 
  may 
  be

  set

  the 
  rule. 
  Among 
  ich- 
  

   thyophagists 
  and 
  great 
  fishing 
  communities, 
  like 
  the 
  people 
  of 
  

   the 
  Hebrides, 
  Iceland, 
  l^eAvfoundland, 
  Greenland, 
  and 
  the 
  coasts 
  

   df 
  Hudson 
  Bav, 
  tuberculosis 
  is 
  rare. 
  In 
  these 
  countries 
  cattle 
  are 
  

   few 
  or 
  absent, 
  or, 
  like 
  the 
  hardy 
  highland 
  kyloes 
  of 
  the 
  Hebrides, 
  

   they 
  are 
  kept 
  in 
  the 
  open 
  air. 
  The 
  immunity 
  of 
  the 
  people 
  is 
  not 
  

   due 
  to 
  insusceptibility, 
  since 
  they 
  fall 
  ready 
  victims 
  to 
  tuberculosis 
  

   when 
  removed 
  to 
  infected 
  countries 
  and 
  cities. 
  

  

  In 
  Northern 
  Sweden, 
  Norway, 
  Lapland, 
  and 
  Finland, 
  where 
  cat- 
  

   tle 
  are 
  scarce 
  and 
  reindeer 
  plentiful, 
  tuberculosis 
  is 
  said 
  to 
  be 
  rare, 
  

   though 
  the 
  inhabitants 
  live 
  in 
  the 
  closest 
  of 
  dwellings 
  through 
  the 
  

   long 
  winter. 
  In 
  most 
  of 
  the 
  Pacific 
  islands 
  there 
  are 
  no 
  cattle, 
  

   and 
  the 
  natives 
  are 
  comparatively 
  free 
  from 
  consumption. 
  In 
  

   Hawaii 
  since 
  the 
  introduction 
  of 
  cattle 
  consumption 
  has 
  increased. 
  

   Australia 
  and 
  Tasmania, 
  which 
  forty 
  years 
  ago 
  were 
  the 
  great 
  

   resorts 
  for 
  English 
  consumptives, 
  have 
  become 
  increasingly 
  the 
  

   homes 
  of 
  infection 
  since 
  the 
  development 
  of 
  the 
  cattle 
  industry 
  and 
  

   the 
  influx 
  of 
  phthisical 
  subjects.
