Supplementary to a paper by Mr. J. B. Simpson, in a previous volume. 



Its object is to clear up some points upon which further information 



vras required. Mr. Lebour was enabled to supply this information 



through notes from M. Cornet. 



The natural pits are circular hollows traversing the Coal Measures, 

 filled with materials which have fallen from above. It was shown that 

 the pits traverse the Cretaceous Beds which overlie the Coal Measures ; 

 but that, so far as is known, they do not penetrate the Tertiaries. The 

 pits show no tendency to narrow downwards ; some are known to in- 

 crease in diameter in that direction. 



The thickness of the beds overlying the Carboniferous Limestone pre- 

 cludes the idea of these pits being swallow-holes. It was suggested that 

 they are the " vents" of trap, the sheet of trap erupted through them 

 having been removed by denudation, and the trap in the vents having 

 been likewise carried away by the long-continued action of springs.
