The only other place where we have found them, is in the bed of the Led- 

 wyche brook, near Caynham Camp, where they are seen at each side of the great 

 fault that throws \ip the Silurian ridge of Tinker's Hill and Caynham Camp. On 

 the N. side of the fault they are seen at the footbridge leading to Caynham Camp, 

 and on the S. side, at the weir below Poughn-hill bridge. 



It would be well if those members of the club, who live near the mapped 

 jvinction of the Ludlow beds, with the Old Red, would try and work out the con- 

 nection in those places, and perhaps something more might be made out. 



Our great guide. Sir R. Murchison, has, I think, fallen into a mistake in 

 reference to these beds, classing them with his tilestones, as Upper Ludlow ; but 

 when he first saw them with me at the railway section some years since, in com- 

 pany with Messrs. Ramsay and Avelin, he would not at all admit of my suggestion 

 that they were Silurian. His present error arises, I believe, from a misnomer by 

 one of our members. Many years ago, we were in the habit of considering the 

 Downton Sandstone (being arenaceous) as the link between the Silurian and the 

 Old Red, and called it Transition Beds. Our friend Mr. R. Banks, as we well 

 know collected a very fine series of fossils, most of them new, from the Downton 

 Sandstone of Bradnor HilL These he generously presented to the Jermyn Street 

 Museiun, but as these Passage Beds had been found about that time, and had ac- 

 quired some celebrity under that name, Mr. Banks seems to have thought that as 

 Transition and Passage mean the same thing, the beds respectively so called must 

 be the same ; indeed he always has considered the Downton Sandstone as not be- 

 longing fairly to the Silurian, and he sent his specimens labelled Passaije Beds. 

 Sir Roderick Murchison, finding, on examination at the Museum, the very same 

 fossils in both Downton Sandstone and Passage Beds, not unnaturally classed them 

 together in the Silurian formation. This, I think, ought not to be done, but the 

 Passage Beds should take their place where Sir Roderick Murchison and Mr. "Wm. 

 Symonds first placed them, viz., 200 or 300 feet up in the bottom of the Old Bed* 



Time was sadly wanted here to work at these beds, but it was "the Ladies 



Day," and there was nothing for it but to get quickly back to Forge Bridge. 



Here they fell in with many groujjs of pretty naturalists, and all wended their 



way along the south bank of the beautiful river which ran murmuring along 



beneath. Sometimes they stopped to pluck a fern, or stooping at a rill side would 



gather 



" That blue and bright-eyed flow'ret of the brook 

 Hope's gentle gem, the fair Forget-me-not." 



A charming walk of nearly a mile ; much too jiretty to be thought long, brought 

 them to Downton Bridge, immediately below the Castle, and passing through a 

 wicket gate, the gorge of the Teme was entered. Here Mr. Richard Payne Knight 

 studied to conceal the care with which he laid out the walks so as to ensure their 

 greatest picturesque effects. 



The sun by this time had come out in full brilliancy, the river was in jier- 

 fection, and whether the walks had been visited or not before, none could fail to
