SWITZERLAND. 



The species which Heer refers to a Jurassic horizon in his Flora 

 Fossilis Helvetia * are few in number, and in several instances too 

 fragmentary to admit of determination. The numerous specimens 

 classed among the Algae are practically valueless for our present 

 purpose.

 higher horizons in the Cretaceous system. Both Heer 2 and
