234 Reports and Proceedings — 



sidered that they were "Keuper," which extended inland to a fault 

 running to the south of Lympstone. A conglomerate rock at the 

 Beacon at Exmouth was probably the upper bed of the "Bunter," and 

 this the author considered to be the same rock that occurred at 

 Cockwood on the right bank of the Exe. This overlies soft red rock, 

 containing occasionally fragments of various rocks, and in the upper 

 part a slight trace of Murchisonite. At Dawlish a soft conglomerate 

 containing Murchisonite in great abundance occurred, this extended 

 inland about two miles. On the westerly side of Dawlish conglomerate 

 beds cropped out, containing fragments of granitic and porphyritic 

 rocks, quartz, Lydian-stone ; and here the limestone fragments con- 

 taining animal remains first occurred. After passing the Parson-and- 

 Clerk Tunnel, these conglomerate beds ceased until reaching Teign- 

 mouth, and the cliffs consist of soft beds. At Teignmouth the 

 conglomerates, with limestone, again commenced, and continued to near 

 St. Mary's Church, in this part alternating with soft sandy or clayey 

 beds. To the north of the fault at Lympstone the Keuper did not ap- 

 pear by the Exe, and the conglomerate with limestone had not been 

 noticed, being possibly buried under the Greensand of Haldon. The 

 beds north of this point on both sides of the Exe were the soft Bed 

 Sandstone, with a trace of Murchisonite, and the underlying Murchi- 

 sonite Conglomerates, and near Haldon House beds that it was 

 considered were possibly those to the west of Dawlish occurred. These 

 beds were broken up by various faults running in both north and south 

 and east and west directions. In the district under consideration it 

 was shown that the soft sandy beds, with a trace of Murchisonite, and 

 the underlying bed of Murchisonite Conglomerate occurred in various 

 places, and in such a manner that there could not be any doubt of their 

 identity ; these the author considered as marking a clear division in the 

 Hed Sandstone. 



2. "On some newly exposed sections of the ' "Woolwich and Beading 

 beds ' near Beading, Berks." By Prof. T. Bupert Jones, E.B.S., F.G.S., 

 and C. Cooper King, Esq., B.M. Art., F.G.S. 



The authors described the section of the Lowest Tertiary Beds lately 

 exposed at Coley Hill, Beading, Berks, comparing it with other sections 

 in the neighbourhood described by Buckland, Bofe, Prestwich, and 

 "Whitaker. At one point in the section oyster-shells are wanting in 

 the Bottom Bed, as observed also by "Whitaker at Castle Kiln. At the 

 same part of the section the leaf-bearing blue clays are also absent, but 

 are continued by irregular thin seams of derived clay and clay-galls, 

 with broken lignite, occasional grey flints, and by at least one green- 

 coated flint and pebble of lydianite. At another point, where the blue 

 clay still exists, very numerous and large lumps of clay, rolled and 

 often inclosing subangular flints, lie in the sand over the leaf-bed. 

 Some of these clay-galls have passed into concentric nodules of ochre 

 and limonite. The probable derivation of the two sets of clay-galls is 

 from pre-existing clay-beds — probably the blue shale, one from its 

 worn end and the other (upper one) from a terrace or ledge in its thick- 

 ness — by the action of varying currents in an estuary at different levels. 

 The clay-galls of the upper series vary much in character; some are of 

 dense dark brown and light coloured clays, others of sandy blue and 

 grey clays, many have involved sand and flints from an old shoal or
