Survey.” The Section at the end of the Memoir differs con- 
siderably from the above figures. The measurements of the 
Selsley Section below the Ragstones, are taken at the north 
end of the hill: at the south-west end the Upper Freestone is 
reduced to six feet and the Oolite Marl to four inches. 
The diminishing importance of the Inferior Oolite in the 
lower Cotteswolds may be the subject of further investigation, 
in which case the Selsley Section will perhaps be found useful 
for correlation. 
Iam indebted to the Rev. A. S. Page, and offer him my 
thanks for taking the heights of the several quarries and 
exposures, which have been of material assistance to me in 
determining the thickness of the more important beds.
