Bead at the General Meeting, ITovemher Ath, 1875. 



WE propose, in a few words, to consider the age of the 

 Cannington Limestone, as it seems to us to have much 

 connection with the question of the probability of finding coal south 

 of the Mendips — at any rate, south of the western part of the chain. 

 The question of finding Coal under the Thames' Yalley was ably 

 put forth by Mr. Godwin Ansten, F.R.S., in 1856 (q.j.g.s. xii, pp, 

 38-73) and the relations of the Mendip axis, with its supposed 

 accompanying Coal Measures, to the secondary rocks was touched 

 upon. It was more fully entered upon in the Eeport of the Coal 

 Commission, being noticed by Prof. Prestwich (loc.cit. 47 and 163 — 

 165) in his contribution to the volame, and his views are summarised 

 iu the main Report (p. xii).
