THE APPEARANCE OF LIFE ON THE GLOBE 323 



Central Bohemia, which form an entire library and 

 a monument which still serves as a basis for all 

 researches on the animals of Primary times. 



The memory of Barrande has remained alive 

 in Bohemia, and it is with legitimate satisfac- 

 tion that a French geologist, when passing through 

 the country round Prague, perceives, on the bank 

 of the Moldau, the name of Barrande graven on the

 written by him. It is, as I said above, a veritable 

 place of pilgrimage. 



Barrande deserves, in all respects, this honour 

 and this worship. Not only did he describe and 

 make known the Silurian fauna of Bohemia, which 

 is doubtless the richest fauna of that epoch known, 

 but he ^iad the merit and the glory of demon- 

 strating that this Silurian fauna was preceded by 

 an earlier world, to which, in the enthusiasm of 

 his discovery, he applied the name of Primordial 

 fauna. 



The strata contemporary with this primordial 

 fauna exists indeed in England, where Sedgwick, in 

 1835, gave them the name of Cambrian, from the 

 old Roman name for Wales. But these layers of 

 sandstone and schist lower than the Silurian, had
