  mites 
  containing 
  the 
  algal 
  deposits 
  have 
  also 
  been 
  formed 
  

   in 
  fresh 
  water. 
  Their 
  exceedingly 
  wide 
  distribution 
  in 
  

   space 
  and 
  time, 
  the 
  huge 
  thickness 
  of 
  the 
  limestones 
  with 
  

   Cryptozoon 
  structures, 
  and 
  above 
  all 
  the 
  fact 
  that 
  marine 
  

   fossils 
  occur 
  in 
  the 
  Ozarkian-Canadian 
  Crypto 
  goon-hear- 
  

   ing 
  rocks 
  of 
  North 
  America 
  can 
  only 
  be 
  explained 
  by 
  the 
  

   assumption 
  that 
  these 
  basins 
  of 
  deposits 
  have 
  also 
  been 
  

   a 
  part 
  of 
  the 
  world-wide 
  oceans.

  The 
  fact 
  that 
  oolites 
  so 
  commonly 
  occur 
  with 
  stromato- 
  

   lites 
  strongly 
  supports 
  the 
  view 
  that 
  we 
  have 
  here 
  to 
  do 
  

   with 
  chemical 
  precipitations. 
  The 
  irregular 
  small 
  con- 
  

   cretions 
  found 
  associated 
  with 
  the 
  stromatolites 
  of 
  the 
  

   Porsanger 
  dolomite 
  may 
  also 
  be 
  regarded 
  as 
  oolites 
  

   ("oolitoids") 
  which, 
  probably 
  through 
  not 
  having 
  been 
  

   able 
  to 
  roll 
  freely 
  on 
  the 
  bottom, 
  have 
  had
