former gentleman considering a large portion of the shaft as 

 representing the Forest Marble, the latter considering it as 

 wholly belonging to the Great Oolite, and contending that certain 

 clay bods, which occur higher in the series, where the true Brad- 

 ford Clay is absent, present a natural division and one which can 

 bo carried out through a wide extent in this district. At a later 

 period of the meeting, the Secretary presented a section of this 

 well \\ith others of the neighbourhood, and read a paper on the 

 Geology of the water-bearing beds about Cirencester. 



HuviMg transacted the usual business of the Club, the members 

 and friends, to the number of 40, sat down to a substantial dinner, 

 which, from its abundance and small cost, was certainly a convinc- 

 ing proof that our dinner bill need not be extravagant when we 

 have a liberal landlord to deal with; at the same time we must 

 bear in mind that our long rambles make us good trenchermen, 

 whilst our moderation in imbibition tends much to limit the usual 

 profit, so that we may not wonder in these days of dearness that, 

 even at the Lamb at Cheltenham, a petition was preferred after 

 our last dinner there for additional pay. 



Well, dinner over, after the usual toasts, and one to the health 

 of the re-elected President and Secretary, followed by that of 

 Professor liamsay, the "Director of the Ordnance Geological Sur- 

 vey, who honored us with his presence, a paper was read by Dr. 

 Wright, on the section of Frocester Hill, the object of which was 

 to show that a certain bed at the base of the Inferior Oolite, and 

 formerly referred to that rock, should, in the Doctor's opinion, be 

 held as part of the Lias ; th ; s view was supported by a reference 

 more particularly to various Cephalopoda, (principally Ammonites 

 and Belemnites,) most of which are peculiar to the bed itself, 

 whilst others are such as belong to the Upper Lias, and at this 

 meeting was introduced the Ammonites lifrons, which was trium- 

 phantly pointed out as proving the case ; and indeed so startling 

 was the production of this shell, as I understood from the bed in 

 dispute, as in a great measure to stifle discussion upon the subject 

 until the matter had been further looked into ; and herein we 

 have much to thank the learned Doctor for in directing our more 

 particular attention to one of the most interesting sections in our 

 county. The result, however, of my own labours at Frocester 

 Hill, leads me to conclude that the Ammonites lifrons in question 

 was obtained from a bed nearly 80 feet below what has been held 

 to be the basement bed of the Inferior Oolite (the Cephalopoda 

 bed of Dr. Wright), and as much as 20 feet from the top of the 

 Upper Lias, and consequently that distance below the Inferior 

 Oolite Sands of the Ordnance Surveyors. However, as this 

 subject came before us at the Pains wick meeting and again at 

 Cheltenham, I shall shortly refer to it in another part of this 

 address, only pointing out that the mistake is easily made, inas- 

 much as the steep scarp at Frocester has long been exposed to the 

 action of the atmosphere, and hence its included iron has become
