MEETING, Decembee 1, 1871. 

 The Peesident in the Chair. 



The fifth meeting for the term was held on 1st December. 

 There were sixty-one members and visitors present. 



The President announced the following contributions to the 

 Museum : — Some Provincial Tokens, mostly of the eighteenth cen- 

 tury, by W. E. Hill ; ancient Indian Coins, by Colonel Lambert ; 

 fragments of a Roman Pavement and a Roman Nail, by E. K. 

 Wedderburn ; Roman and other Coins, discovered at Dover, by 

 Mrs Buchanan ; a large case of PaUeozoic Fossils from Ireland, 

 by the Irish Geological Survey. A vote of thanks to Mr Edward 

 Hull, through whom we obtained these fossils, was proposed by 

 the President, seconded by Rev. J. Greene, and carried. Rev. J. 

 Greene presented, on behalf of J. Carver, Esq., Chilton Polden, 

 Bridgewater, a very fine specimen of the Camberwell Beauty 

 (Vanessa antioim). It was taken by Mr Carver, on the 13th 

 August 1870, while sipping the juices of an apricot tree in his 

 garden. It has unfortunately lost its antennae, otherwise it is in 

 beautiful condition; and being an undoubted British example, is a 

 most valuable addition to the Museum collection of Lepidoptera. 

 The Secretary was directed to forward to Mr Carver an exiDression 

 of thanks on behalf of the Society for his gift. 



H. Wills then read the following paper on — 



AUST CLIFF. 



Rising from the midst of the alluvial deposits round the mouth 

 of the Severn, are several eminences and formations of older date, 

 belonging to the strata which underlie and skirt the alluvial ]Aam. 

 On the left bank of the river the principal formations to be found 

 are the lias, triassic beds of the new red sandstone, inferior oolite, 

 and small patches of carboniferous limestone. The beds generally 

 are very much broken ; but proceeding further away from the river 

 we find an enormous mass of the great oolite, which extends over 

 a wide space of the county. 



Aust Cliff is surrounded by long fiats of alluvial mud, while on 

 the opposite side of the river we find a corresponding elevation, 

 called Aunard's Cliff" ; the latter is lower than the former, though 

 that never exceeds sixty feet at its highest. 



It is composed of rocks resting unconformably upon the car- 

 boniferous limestone, the beds of which are very much tilted,
