148 THE DAWN OF LIFE.

 pared with tlie Canadian. 



Giimbel also found in the Finnish and Bavarian 

 limestones knotted chambers^ like those of Wentworth 

 above mentioned (fig. 36), which he regards as be- 

 longing to some other organism than Eozoon ; and 

 flocculi having tubeSj pores, and reticulations which 

 would seem to point to the presence of structures 

 akin to sponges or possibly remains of seaweeds. 

 These observations Giimbel has extended into other 

 localities in Bavaria and Bohemia, and also in Silesia

and Sweden, establishing the existence of Eozoon 

 fossils in all the Laurentian limestones of the middle 

 and north of Europe. 



Giimbel has further found in beds overlying the 

 older Eozoic series, and probably of the same age with 

 the Canadian Huronian, a different species of Eozoon, 

 with smaller and more contracted chambers, and still 

 finer and more crowded canals. This, which is to be 

 regarded as a distinct species, or at least a well-marked 

 varietal form, he has named Eozoon Bavaricum (fig. 

 37). Thus this early introduction of life is not peculiar 

 to that old continent which we sometimes call the New
