As President of the Geological Society, noticing the announcement 

 made by Dr. Dawson of ' ' the occurrence of Eozoon preserved simply in 

 carbonate of lime," declared that this " discovery of Eozoon preserved in 

 carbonate of lime pure and simple would appear to close the discussion."

Note on Eozoon. 



After describing the roundish grains of serpetine (which are considered 

 to have been originally peridote) occurring in the crystalline limestones 

 (hemithrenes) of Aker, Pargas, Modum (Scandinavia), the author's in- 

 vestigations, it is stated, " did not reveal the canal system which is called 

 eozoonal structure." But it must be mentioned that we have detected 

 in specimens from Aker beautiful examples of " canal system." (King 

 and Rowney. An old chapter of the Geol. Rec, p. xxvi, 1881.)
