The party divided into two sections^ ArcliEeological and 

 Geological; the former, under the guidance of Mr. J. D. T, 

 NiBLETT, proceeding to visit the ancient Church at Elkstone, 

 about three miles distant ; while the geologists, under the 

 guidance of Professor Buckman, made their way to the neigh- 

 bouring quarries, to hear the learned Professor correlate certain 

 beds exposed in that well-known escarpment with those of the 

 same formation in Dorset. The Professor intimated that during 

 the walk he should shew that the Cephalopoda-bed of Dorset, 

 which was regarded by Dr. Weight and other Cotteswold 

 geologists as liassic, and as the equivalent of the Cephalopoda- 

 bed of Gloucestershire, also termed liassic, was really not at 

 the bottom but at the top of the Inferior Oolite. Proceeding 

 in the direction of Crickley hill, the party halted on the slope 

 facing the line section there exposed, while the Professor 

 developed his views on the correlation of the beds in question. 

 The substance of his remarks was, that the Cephalopoda-bed 

 of Dorset is not the equivalent of the Cotteswold bed, but 

 occupies the position of the Gryphite bed at Leckhampton and 

 elsewhere; that the Inferior Oolite of the Cotteswolds is in 

 Dorset represented by Sand, but that in a bed of about two feet 

 in thickness, nearly all the fossils of the Inferior Oohte of 

 Gloucestershire, including the Ammonites of the Cephalopoda- 

 bed, are found ; hence he inferred that the division of the 

 Inferior Oolite of Gloucestershire into zones founded on some 

 of these Ammonites, was a mistake. Dr. Wright, in reply, 

 emphatically denied the presence in the Dorset bed of the 

 liassic Ammonites, A. opalinus, A. Jurensis, and A, striatulus. 

 The discussion continued during the progress of the party 

 round the base of the quarries, but eventually the Professor 

 and Doctor agreed that the beds were not identical, so that the 

 question of the zones only remained for discussion after the 

 reading of Professor Buckman's paper in the evening. 



Mr. WiTCHELL called attention to a bed of oolitic rubble and 

 angular gravel on the slope of the hill, as bearing upon the 

 subject of a paper to be read by him. The party returned over
