At Fresliford there is a good section of the Lower Level 

 Gravels resting on Lias Sands, which Gravels have yielded Bos 

 moschatusy Elephas frimigenius, &c. Attention was drawn to 

 the mixed character of the Gravels, with which, together 

 with a preponderance of Oohtic detritus, is associated much 

 Carboniferous Limestone, Old Eed, and Chalk Flints, together 

 with a very appreciable admixture of haematitic Iron Ore. The 

 mixed character of these accumulations is due to denudation 

 from the Chalk of Wiltshire in one direction, and from the 

 Mendips in another, occurring as they do at the point of junction 

 of the Frome valley vdth that of the Avon, whose divergent 

 channels command the respective sources of supply. 



The party crossed the Avon, and followed the line of the 

 Canal, which exhibits a good section of the Parkinsoni beds of 

 the Inferior Oolite, about thirty feet thick, resting on the Lias 

 Sands. These beds are overlaid by a great thickness of Fullers 

 Earth, capped by Great OoUte, a sequence which is characteristic 

 of all the hiUs around Bath. 



The following local plants were observed in bloom in or near 

 the Canal : — 



Carex vulpina Sagittaria sagittalis 



Butomus umbellatus Nuphar lutea 



Origanum vulgare Scutellaria vulgaris 



Chlora perfoliata 



At Dundas aqueduct a quarry was examined exhibiting 

 sections of Upper and Middle Lias, (Marlstone,) the former not 

 exceeding three feet in thickness, containing Am. communis and 

 serpentinus. The Marlstone, which is rarely exposed in the 

 neighboxurhood of Bath, was characterised by Lingula Beanii in 

 great abundance. 



Passing by "The Brass Knocker" the party reached the 

 Great Oolite on Hampton Down, from whence they returned to 

 Bath, and dined at the Eoyal Hotel. 



After dinner Mr. Charles Moore, at the request of the 

 President, gave an outline of his views respecting the beds at 

 Sutton and Southemdown, near Bridgend, which have long been 

 a crux to Geologists. But the more immediate interest of the
