  apparently 
  different 
  from 
  any 
  known 
  species. 
  It 
  is 
  deciduous, 
  and 
  no 
  doubt 
  will 
  

   prove 
  perfectly 
  Lardy 
  in 
  the 
  gardens 
  of 
  this 
  country.'' 
  

  

  Mr. 
  Baly 
  exhibited 
  some 
  bees 
  which 
  had 
  been 
  preserved 
  in 
  spirit, 
  and 
  restored 
  to 
  

   their 
  pristine 
  beauty 
  by 
  washing 
  with 
  soap 
  and 
  warm 
  water, 
  the 
  pile 
  being 
  dried 
  and 
  

   raised 
  with 
  blotting 
  paper. 
  

  

  Mr. 
  Waterhouse 
  said 
  he 
  had 
  often 
  treated 
  insects 
  of 
  all 
  orders, 
  except 
  Lepidoptera, 
  

   in 
  this 
  way, 
  even 
  when 
  they 
  were 
  greasy, 
  with 
  the 
  greatest 
  success, 
  and 
  Mr. 
  Edward 
  

   Sheppard 
  also 
  spoke 
  in 
  its 
  favour.

  " 
  Through 
  the 
  kindness 
  of 
  Dr. 
  Quain, 
  of 
  Harley 
  Street, 
  Cavendish 
  Square, 
  I 
  am 
  

   enabled 
  to 
  lay 
  before 
  the 
  Society 
  specimens 
  of 
  the 
  African 
  Dipterous 
  insect, 
  ' 
  Tsetse^ 
  

   communicated 
  to 
  him 
  by 
  William 
  Oswell, 
  Esq., 
  who 
  has 
  travelled 
  extensively 
  in 
  

   Africa; 
  and 
  also 
  the 
  following 
  very 
  interesting 
  memorandum 
  respecting 
  it, 
  by 
  the 
  same 
  

   gentleman, 
  who 
  informed 
  him 
  that 
  on 
  one 
  occasion 
  he 
  lost 
  forty-nine 
  out 
  of 
  fifty-seven 
  

   oxen, 
  of 
  which 
  his 
  teams 
  consisted, 
  from 
  the 
  attacks 
  of 
  this 
  insect, 
  and 
  that 
  the 
  inter- 
  

   val 
  from 
  their 
  being 
  first 
  attacked 
  to 
  their 
  death, 
  varied 
  from 
  three 
  to 
  twelve 
  weeks. 
  

  

  " 
  ' 
  Tsetse. 
  — 
  This 
  fly, 
  which 
  is 
  the 
  same 
  as 
  that 
  found 
  to 
  the 
  eastward 
  of 
  the 
  Lim- 
  

   popo, 
  infests 
  the 
  country 
  of 
  Sebitoeni, 
  a 
  chief 
  living 
  between 
  the 
  18th 
  and 
  15th 
  degrees 
  

   of 
  South 
  latitude, 
  and 
  the 
  24th 
  and 
  28th 
  of 
  East 
  longitude. 
  It 
  is 
  fortunately 
  confined 
  

   to 
  particular 
  spots, 
  and 
  is 
  never 
  known 
  to 
  shift. 
  The 
  inhabitants 
  herd 
  their 
  cattle 
  at 
  

   a 
  safe 
  distance 
  from 
  its 
  haunts 
  ; 
  and 
  should 
  they, 
  in 
  changing 
  their 
  cattle-posts, 
  be 
  

   obliged 
  to 
  pass 
  through 
  tracts 
  of 
  country 
  in 
  which 
  it 
  exists, 
  they 
  choose 
  a 
  moonlight 
  

   winter's 
  night, 
  as 
  during 
  the 
  nights 
  of 
  the 
  cold 
  weather 
  it 
  does 
  not 
  bite. 
  From 
  what 
  

   I 
  have 
  seen, 
  I 
  believe 
  that 
  three 
  or 
  four 
  flies 
  will 
  kill 
  a 
  full-grown 
  ox. 
  We 
  examined 
  

   about 
  twenty 
  of 
  ours 
  which 
  were 
  bitten 
  and 
  died, 
  and 
  the 
  appearances 
  were 
  similar 
  in 
  

   all. 
  On 
  raising 
  the 
  skin, 
  a 
  glairy 
  appearance 
  of 
  the 
  muscles 
  and 
  flesh 
  (which 
  was 
  

   much 
  wasted) 
  presented 
  itself. 
  The 
  stomach 
  and 
  intestines 
  healthy 
  ; 
  the 
  heart, 
  lungs 
  

   and 
  liver, 
  sometimes 
  all, 
  and 
  invariably 
  one 
  or 
  the 
  other, 
  diseased 
  ; 
  the 
  heart 
  in 
  parti- 
  

   cular 
  attracted 
  our 
  attention, 
  it 
  was 
  no 
  longer 
  a 
  firm 
  muscle, 
  but 
  collapsed 
  readily 
  on 
  

   compression 
  of 
  its 
  walls, 
  and 
  had 
  the 
  appearance 
  of 
  flesh 
  that 
  had 
  been 
  steeped 
  in 
  

   water. 
  The 
  blood 
  was 
  greatly 
  diminished 
  in 
  quantity 
  and 
  altered 
  in 
  quality 
  ; 
  not 
  

   more 
  than 
  twenty 
  pints 
  could 
  be 
  obtained 
  from 
  the 
  largest 
  ox, 
  and 
  that 
  thick 
  and 
  

   albuminous; 
  the 
  hands, 
  when 
  plunged 
  into 
  it, 
  came 
  out 
  free 
  of 
  stain. 
  The 
  poison 
  

   would 
  seem 
  to 
  grow 
  in 
  the 
  blood, 
  and 
  through 
  it 
  to 
  affect 
  the 
  vital 
  organs. 
  All 
  domes- 
  

   ticated 
  animals, 
  save, 
  I 
  believe, 
  goats, 
  die 
  from 
  the 
  bite 
  of 
  this 
  insect. 
  Calves 
  and 
  

   sucking 
  animals 
  however 
  are 
  not 
  affected 
  ; 
  and 
  man 
  and 
  all 
  wild 
  animals 
  are 
  bitten 
  

   with 
  impunity. 
  The 
  symptoms 
  of 
  the 
  bite 
  are 
  swelling 
  of 
  the 
  eyelids 
  and 
  a 
  watery 
  

   discharge 
  from 
  the 
  eyes, 
  and 
  considerable 
  enlargement 
  of 
  the 
  sublingual 
  glands.'
