The division of the palseozoic series adopted by M, Dumont for the 

 beautiful Geological Map of Belgium, which he has just completed 

 by order of the Belgian Government, must necessarily produce a 

 change in many of the views of English geologists ; since he has now 

 worked out, by the strict evidence of superposition, the order of the 

 formations lying between the old unfossiliferous slates of the Ardennes 

 and the Carboniferous series, while the unconnected position of those 

 formations m England has prevented us from ascertaining their rela- 

 tive ages with certainty. Having had the advantage, in company 

 with several of our colleagues, of discussing with M. Dumont the 

 value of his divisions and of inspecting the fossils collected from them, 

 I hasten to bring the matter to the notice of the Society, that the 

 valuable results of M, Dumont' s labours may be made known and 

 applied here. 



The following extract from M. Dumont's "Tableau des Terrains 

 de la Belgique " contains the description of the older stratified rocks,
