Notice of Fossil Footsteps in the New Red Sandstone at 

 Lymm, in Cheshire, by Mr. Hawkshaw. — The rock underlying 

 the strata is a thick bedded sandstone, deeply impressed with 

 oxide of iron, and very indistinctly stratified. Fossil footsteps 

 had been found in nearly all the sandstone beds; those of the up- 

 per part were small pointed impressions, resembling the tracks of 

 Crustacea ; others were like the feet of birds ; footsteps of the 

 Cheirotherium also occurred in the upper beds, but they were of 

 small dimensions, and appeared to increase in magnitude as the 

 beds descended.
