 in the supposed Archaean nucleus of the Alps. 



Gumbel also found in the Finnish and Bavarian

 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,
