Bemarhs on Drybt'ook Section. By John Jones, F.G.S., 

 F.A.S.L., &c. 



As the Cotteswold Club has determined to publish in detail 

 the Section measured and taken by Mr. Lucy and myself at 

 this place, I beg leave to offer the following remarks upon 

 it, -by way of explanation. Smce I assisted in taking this 

 Section, I have had the privilege of visiting many localities in 

 Belgium, where the Carboniferous Limestone is developed 

 to an extent which can hardly be paralleled in any part of 

 the world; and I can conscientiously state, that I have 

 never seen such a series of beds intermediate between the 

 upper beds of the universally recognized Old Eed Sandstone 

 formation, and that of the Carboniferous Limestone, as at 

 Drybrook. They are, so far as my information extends, strictly 

 local, as there are others differing remarkably in character, 

 underlying the Carboniferous Limestone, at no greater distance 

 than the Lea Bailey, upon the north-east extremity of the 

 Forest of Dean coal basin, which are easily accessible, and 

 which I wotdd suggest, should be pubHshed by the Club in 

 similar form, and upon a like scale, as a proper collateral with 

 the present. 



We must recollect, that shallow-sea and deep-sea conditions 

 must at all times have been coincident, and that the beds at 

 Drybrook, without fossils until we come to their upper portion, 

 may represent one state of things, and those of the Lea Bailey 

 with the SpirorUs band, the other. I remember having found 

 some flakes of the latter, which are very thin. I think Lord 

 Ducie has the specimens, with other fossils found upon the 

 occasion of ovir visit, at a Mitcheldean meeting.
