﻿520 
  Seventh 
  Annual 
  Repoet 
  of 
  the 
  

  

  If 
  we 
  now 
  contrast 
  tins 
  fearful 
  mortality 
  with 
  the 
  immunity 
  of 
  

   the 
  Indians 
  of 
  Hudson 
  Bay, 
  Great 
  Slave 
  Lake, 
  Alaska, 
  and 
  the 
  

   North 
  generally, 
  we 
  have 
  a 
  more 
  suggestive 
  picture. 
  It 
  may 
  be 
  

   conceded 
  that 
  the 
  extreme 
  Northern 
  Indians, 
  being 
  beyond 
  the 
  

   cereal 
  region, 
  have 
  a 
  slight 
  measure 
  of 
  protection 
  in 
  their 
  meat 
  

   diet; 
  but 
  the 
  recent 
  spread 
  of 
  tuberculosis, 
  like 
  a 
  plague, 
  among 
  

   the 
  inhabitants 
  of 
  Barrow 
  Straits, 
  when 
  introduced 
  by 
  the 
  frozen-in 
  

   whalers 
  and 
  the 
  relief 
  party, 
  is 
  sufficient 
  disproof 
  of 
  any 
  claim 
  of 
  

   special 
  insusceptibility. 
  There 
  can 
  be 
  no 
  doubt 
  that 
  in 
  this, 
  aa 
  

   in 
  other 
  virulent 
  diseases, 
  the 
  rule 
  holds 
  that 
  the 
  long 
  absence 
  of 
  

   the 
  infection 
  secures 
  the 
  preservation 
  of 
  the 
  susceptible 
  lines 
  of 
  

   blood, 
  so 
  that 
  when 
  the 
  contagion 
  does 
  come, 
  it 
  finds 
  a 
  more 
  in- 
  

   viting 
  field 
  than 
  in 
  countries 
  in 
  which 
  the 
  more 
  susceptible 
  strains 
  

   have 
  been 
  killed 
  off 
  and 
  the 
  comparatively 
  immune 
  have 
  survived. 
  

   Toward 
  the 
  Arctic 
  circle 
  the 
  Indian 
  must 
  crowd 
  into 
  closer 
  quar- 
  

   ters 
  in 
  winter 
  than 
  his 
  brother 
  further 
  south; 
  but, 
  in 
  spite 
  of 
  all, 
  

   the 
  beef-eating 
  Indian 
  is 
  being 
  rapidly 
  exterminated 
  by 
  tubercu- 
  

   losis, 
  to 
  which 
  his 
  brother 
  of 
  the 
  north 
  is 
  a 
  comparative 
  stranger. 
  

  

  Exceptions: 
  Their 
  explanation. 
  This 
  statement 
  would 
  be 
  in- 
  

   complete 
  without 
  a 
  notice 
  of 
  exceptions 
  to 
  the 
  rule. 
  The 
  Cape 
  

   Town 
  branch 
  of 
  the 
  British 
  Medical 
  Association 
  reports 
  " 
  that 
  

   tuberculosis 
  is 
  rapidly 
  increasing 
  there 
  in 
  the 
  human 
  population, 
  

   while 
  tubercle 
  in 
  cattle 
  is 
  almost 
  non-existent." 
  This 
  finds 
  an 
  

   abundant 
  explanation 
  in 
  the 
  different 
  conditions 
  of 
  life. 
  The 
  

   men 
  live 
  indoors 
  and 
  concentrate 
  the 
  infection, 
  whereas 
  the 
  cattle 
  

   enjoy 
  an 
  outdoor 
  life 
  and 
  escape. 
  In 
  a 
  latitude 
  of 
  30 
  degrees 
  

   south, 
  where 
  frost 
  is 
  almost 
  unknown, 
  and 
  with 
  a 
  dry 
  climate 
  

   (12 
  to 
  30 
  inches 
  of 
  rain 
  per 
  annum), 
  the 
  colonists 
  find 
  no 
  occa- 
  

   sion 
  for 
  housing 
  their 
  cattle, 
  so 
  that 
  the 
  conditions 
  for 
  the 
  preven- 
  

   tion 
  of 
  tuberculosis 
  are 
  ideal. 
  It 
  may 
  be 
  added 
  that 
  cattle 
  are 
  far 
  

   less 
  numerous 
  in 
  Cape 
  Colony 
  than 
  they 
  formerly 
  were. 
  The 
  de- 
  

   struction 
  first 
  by 
  lung 
  plague 
  and 
  later 
  by 
  rinderpest 
  has 
  made 
  

   the 
  cattle 
  industry 
  extremely 
  hazardous 
  and 
  even 
  before 
  the 
  advent 
  

   of 
  the 
  rinderpest 
  many 
  had 
  abandoned 
  cattle 
  and 
  taken 
  to 
  sheep. 
  

  

  Parallel 
  cases 
  can 
  be 
  found 
  in 
  other 
  countries. 
  In 
  Egypt, 
  the
