 in the supposed Archaean nucleus of the Alps. 



Giimbel also found in the Finnish and Bavarian 

 limestones knotted chambers, like those of Went- 

 worth above mentioned (Fig. 55), which he regards 

 as belonging to some other organism than Eozoon ; 

 and flocculi having tubes, pores, and reticulations

 limestones of the middle and north of Europe. 



Giimbel has further found in beds overlying the

 with the Canadian Huronian, a different species of 

 Eozoon, with smaller and more contracted cham- 

 bers, and still finer and more crowded canals. This,
