Yol. 6^.~] OF THE BATH-DOTTLTOTG DISTRICT. 421 



of Dundry Freestone. From observations recorded by Sir William 

 Guise, in his valuable 'iSTotes on the Inferior-Oolite Beds in the 

 Neighbourhood of Bath,' 1 it appears that the Freestone here is 

 about 27 feet thick. Sir William was fortunate in visiting the 

 quarry at a time when a well was being sunk through the floor. 

 The ' Trigonia- and Sjnnosa-Grit ' (Upper Trig onia -Grit) was proved 

 below the Freestone, and, according to Sir William, was 



'precisely identical in characters with the " basement-bed " at Lympley Stoke, 

 and like that charged with Trigonia costata and Bhyncho?iella spinosa' {op. cit. 

 P- 174), 



and 3 feet thick. It rested upon ' Blue Clay 4 or 5 feet/ which in 

 turn reposed on ' Sand.' He proceeds to remark that 



' The clay-band would appear to be a merely local and accidental deposit ; and 

 I heard a story of a man whose well was supplied from this stratum, who, 

 not being satisfied with the quantity of water yielded, and desiring to increase 

 the supply, penetrated to the underlying sands, and lost the pure element 

 altogether.' {Ibid. pp. 174-75.) 



Above the ' Coralline Beds ' in the Church Quarry would have 

 come the Doulting Stone and the Anahacia-~Limes,tones, had they 

 not been removed by denudation. At Barns Batch and Barns-Batch 

 Spinney, however, are the beds concerning the correct strati- 

 graphical position of which Mr. S. S. Buckman & the late Edward 

 Wilson were in doubt. 2 I visited both sections, but neither was in 

 a, satisfactory condition — especially that at the Spinney. Conse- 

 quently I am unable to forward matters ; but, in view of what has 

 been stated in this paper, the probability is that the Barns-Batch 

 Freestone-Beds were deposited subsequently to the ' Coralline Beds/ 

 and that they correspond to the Doulting Freestone and the Anabacia- 

 Limestones. 



Since, as is now known to be the case, the Upper Tingonia-Qvit 

 and the Upper Coral-Bed have so wide a geographical range in the 

 West of England, and the Doulting Beds, either in their typical 

 form or as Clypeiis-Giit and White Oolite (as at Horton in the 

 South Cotteswolds), or as the Clypeus-Grit proper, extend over 

 an even greater area, it would be surprising indeed if representa- 

 tives of the Doulting Beds were absent from Dundry Hill. They 

 are most probably represented by the Barns-Batch beds, and the 

 likelihood that we are near the top of the Inferior-Oolite Series 

 is strengthened by the interesting discovery, made by my friend, 

 Mr. J. W. D. Marshall, of a pocket of Fullers' Earth preserved in a 

 cleft in the Inferior-Oolite rocks near Castle Farm, at the western 

 end of the hill. Mr. Marshall has favoured me with the following 

 observations : — 



' The occurrence of Fullers' Earth was first suggested by the discovery of 

 several specimens of Bhynchonetta Smithi on one of the spoil-heaps of the 

 quarry at "West End " in 1901. In 1902, Mr. B. J. Buckman picked up in 

 my presence a well-developed example of Omithella cadomensis — the form 

 which is not uncommon at Midford in the Fullers' Earth. On the occasion of 

 another visit, I found that the whole face of the middle portion of the section
