1. Observations on a Slab of New Red Sandstone from the Quarries 

 at Weston, near Runcorn, Cheshire, containing the Impres- 

 sions of Footsteps and other markings. By J. Black, Esq., 

 M.D., I.G.S. 



Plate V. 



The notices of fossil impressions of footsteps in the New red sand- 

 stone are now sufficiently numerous, as well in Warwickshire and 

 Shropshire as in Cheshire, to take away the interest of novelty from 

 any discovery of this nature ; yet I consider the slab about to be 

 described sufficiently new to justify my laying the following account 

 of it before the Geological Society. 



The summit of the quarry of New red sandstone whence this spe- 

 cimen was extracted by Mr. Feraday Smith is about 100 feet above 

 the level of the Mersey at Weston. The rock is here worked per- 

 pendicularly to about fifty feet from the top, and the seams which 

 contain the impressions are two in number and are nearly three feet 

 apart, the higher being twenty-four feet from the top. Both these 

 seams consist of from half to three-quarters of an inch of reddish 

 silty clay, upon which when soft the impressions have been made, 

 and the lower series has larger and better-defined marks tlian the 

 other. The beds dip to the south-west at an angle of about 10"^, and 

 are of a red colour and coarse grain.
