TABLE O. The Primordial Flora and Fauna and their Recurrents (1868). 



We owe the rich Primordial harvest gathered in Newfoundland and Anticosti Island to the 

 enterprise and skill of Mr. Richardson, as directed by Sir W. E. Logan. 



THE SILURIAN BASIN OF CENTRAL BOHEMIA. After premising a few necessary remarks, it is 

 intended here to give a rapid sketch of the principal features of the Bohemian Basin ; then, 1st, 

 some statements will be made as to the places where its fauna make their first appearance ; 2ndly, 

 its zoological relations with other countries will be noticed ; and, 3rdly, there will follow a short 

 account of one of its great Molluscan communities. The scope of these observations forbids any 

 allusion to several other interesting subjects of a kindred nature. This abundant life M. Barrande 

 has exhumed and described with consummate skill and alone, treading for thirty years the solitary 

 and toilsome path appointed for every great workman. M. Barrande entered on his palseontological 

 studies with a preparedness and breadth of view very rare at that time (1838). Availing 

 himself of the little already done by his predecessors, he has ascertained the external limits and 

 true subdivisions of his fossil-bearing territory. Its organic contents he has grouped according 

 to place and stratum, noting their natural relations, their movements, vertical and horizontal, 

 following out also their several structural developments. There are particulars included 

 within these heads of descriptive natural history which are absolutely necessary to any good 

 generalization, but which previously had been almost unthought of. It is by such enlightened 

 and prescient labours that M. Barrande has been able to examine so successfully a district of
