Thus we get a fairly constant thickness of the London Clay from 

 Odiham on the west, to Ash on the east, when it thickens to the 

 east at Brookwood. 



Moreover, besides the passage from the London Clay up into the 

 Bagshot beds, at the Wellington-College well (Rev. A. Irving, 

 Quart. Lourn. Geol. Soc. xli. p. 506), similar passages are shown in 

 the Brookwood well and in the one at D Lines, South Camp, Aider- 

 shot ; so at these points there can have been no great erosion or 

 great unconformability. The overlying Bagshot Beds too, as I have 

 endeavoured to show, lie conformably on the London Clay and on 

 one another so far as Aldershot is concerned ; and the exposure of 

 the Lower London Tertiaries to denuding agencies in Bagshot times 

 cannot have been so near the Bagshot area as Aldershot. 



Discussion. 



The Peesident congratulated the Society on the acquisition^ a 

 recruit whose carefully plotted sections did credit to his training as 

 an officer of the Royal Engineers. 



Mr. Ieving observed that the Author had the advantage of being
