Whilst this sheet was passing through the press my esteemed friend Mr. W. W. 

 Stoddart, E.G.S., of Bristol, kindly sent me a detailed section of Dundry Hill, measured 

 by himself, with the vertical thickness and barometrical height of the chief beds in the 

 section in feet. This I have endeavoured to embody in the form adopted in this vpork ; 

 and I thank my friend for the same.
