  TULLBERG, 
  GRAPTOLITES 
  DESCRIBED

  most 
  with 
  certainty 
  be 
  concluded, 
  that 
  he 
  by 
  bis 
  clescriptioD 
  

   meant 
  to 
  indicate 
  a 
  Dictyonema. 
  Notbing 
  in 
  bis 
  descriptiou 
  

   forbids 
  sucb 
  a 
  supposition. 
  He 
  denominates 
  it: 
  »musci 
  ramosi 
  

   capillamenta 
  nigra», 
  and 
  compares 
  it 
  furtber 
  with 
  a 
  dendrite. 
  

   At 
  tbe 
  same 
  time 
  bowever, 
  be, 
  as 
  it 
  appears 
  above, 
  points 
  out 
  

   its 
  dissimilarity 
  to 
  sucb 
  forms. 
  

  

  Dictyonema 
  jiahelliforine 
  is 
  very 
  comraon 
  in 
  the 
  youngest 
  

   aluminaceous 
  shales 
  of 
  Ostrogotbia; 
  and 
  in 
  other 
  provinces 
  

   also 
  balls 
  of 
  anthraconite 
  are 
  frequently 
  found 
  in 
  the 
  similar 
  

   strata, 
  which 
  contain 
  the 
  same 
  fossil, 
  as 
  shown, 
  when 
  they 
  

   are 
  split 
  open.

  It 
  is 
  highly 
  probable, 
  that 
  this 
  mineral 
  from 
  Vestrogothia 
  

   was 
  a 
  sbale 
  containing 
  graptolites. 
  Wahlenberg^)

   this 
  to 
  have 
  been 
  the 
  case. 
  

  

  Among 
  others 
  Bbomell 
  is 
  remarkable 
  for 
  bis 
  advanced 
  

   opinions 
  on 
  the 
  nature 
  of 
  fossils, 
  which 
  he 
  enunciates 
  so 
  

   clearly 
  as 
  to 
  leave 
  no 
  doubt 
  of 
  what 
  he 
  mcans. 
  He 
  says 
  

   expressively 
  : 
  »animalia 
  eorumque 
  partes 
  våris, 
  haud 
  minus 
  

  

  crushed 
  and 
  powdered 
  by 
  the 
  peasantry 
  as 
  a 
  medicine 
  for 
  sickly 
  domestic 
  

   animals. 
  Doses 
  of 
  this 
  material 
  are 
  given 
  especially 
  to 
  swine: 
  from 
  which 
  

   circumstance 
  also 
  its 
  name 
  is 
  derived.
