The strata were bent over in an anticline that trended in a 
northerly and southerly direction, so that the beds dipped away 
towards the east and west. The full thickness of the Great 
Oolite Clay could not be measured. The accompanying section 
is diagrammatic, although based on the evidence furnished in 
different parts of the pits opened.

The evidence on which we have to rely in this neighbourhood, 
shows that the Cornbrash maintains its ordinary characters ; an.i 
that we are not justified in including with it those clayey beds, 
which, when the Geological Survey was made, it was considered 
desirable to associate with the Cornbrash, and which gave a 
thickness of 40 feet or more to the formation.* 
In the country extending by Beachampton and Stony Stratford 
to Newport Pagnell, the upper boundary of the Cornbrash is 
hidden by Drift, but occasional sections are afforded of the junc- 
tion with the Forest Marble or 'Great Oolite Clay and the

In Bedfordshire again the outcrop of the Cornbrash is to a

to the west and north-west of Bedford, shows not only that the
