﻿CONCLUSION.

just mentioned. These asli and slate beds are succeeded conformably by the Ramslcigh 

 limestones; but in the quarry it is next to impossible to make out stratification at all. 

 Woolborough quarry is an outlier of limestone full of fossils, and the ground between it 

 and Ramslcigh is occupied with grits of Carboniferous age, which entirely conceal the 

 Devonian beds. Moreover, it is quite impossible to make out stratification at Woolborough. 

 To use Murehison's expression in October last, " it is a charming piece of bedevilled 

 limestone." 



Before proceeding further, we may at once jot down in a tabular view all the Upper 

 and Lower Devonian species we have been able to examine, with their distribution in 





Middle Devonian.
