01ST THE WALTON-COMMON SECTION. 



If the London Clay passed into the Bagshots there was an end to 

 the unconformity for which Mr. Irving contended. 



Mr. Ieving said, in explanation, that he had only argued that 

 there was unconformity on the margins of the area. The case 

 he had mentioned confirmed the well-sections he had previously 

 quoted. There is no such passage in the surface-sections on the 

 north side. 



Mr. H"cdlesto2J was glad Mr. Whitaker thought that the Hatch 

 brick-earth on AVoburn Hill might be Lower Bagshot, and heartily 

 agreed with his objections to the term Bagshot Sands.
