192 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Jan. 12, 
it was constantly the case that the marl rested immediately on the 
paleozoic rocks without the intervention of the Bunter Sandstone. 
He thought that there were good grounds for connecting the Rheetic — 
beds with the New Red Marl below and the Lias above. The pro- 
bability was that the change in character was due to a gradual 
influx of the sea into the inland lakes. He thought that the Theco- 
dont Saurians might also eventually be found even in beds of 
Liassic age. 
Prof. T. Rueert Jonns remarked that Mr, Tawney and Dr. Duncan 
had already intimated the St.-Cassian aspect and character of the 
Sutton beds. The freshwater character of some of the Keuper beds 
was, he remarked, indicated by the presence of Hstheriw ; and he 
alluded to the fact of the Bristol Paleosaurians having been erro- 
neously used as Permian characteristics in Russia and Carolina. 
Mr. W. Boyp Dawkins had found at Cheddar that the Dolomitic 
Conglomerate formed two great tongues running up ravines in the 
older rock, which had probably been due to subaérial action. 
Prof. Morris alluded to some sections which seemed to corrobo- 
rate the views of Mr. Etheridge, and pointed out the relation of the 
Conglomerate beds to the overlying strata at those points. He also 
mentioned certain peculiarities in the structure of the conglomerate 
itself. 
Mr. Erurripce stated in reply that the Marls in the Bristol 
area were the exception, the greater part of the New Red beds 
being sandstone. 
2. On the SurFacse-pEposits in the NurcuBourHoop of Rucsy. By 
J. M. Witson, Esq., M.A., F.G.S., Mathematical and Natural- 
Science Master in Rugby School, late Fellow of St. John’s College, 
Cambridge. 
I pewizrve no detailed information about the surface-deposits in the 
neighbourhood of Rugby has been communicated to this or to any 
Society ; and I therefore offer the following observations, which fall 
under two heads :—— 
(1) The surface-deposits of the high levels. 
(2) The deposits in the valleys. 
In the present paper I confine myself strictly to facts for which 
I hold myself responsible as resting on my own observation, or on 
information obtained on the spot on which I can rely. 
Physical Geography. 
There is a plateau of irregular shape, of which the southern edge 
is well defined, on which the villages of Bourton, Thurlaston, Dun- 
church, and Hillmorton are placed. From this line, which faces 
S.8.E., the eye ranges over the wide valley of Birdingbury, Gran- 
borough, and Willoughby. The height-of the plateau above the 
level of the valley is about 120 fect. The platcau has a slight slope
