statements of other geologists, who have generally adopted with regard 

 to one of the points discussed a diiferent inference, as the sandstone of 

 the Eden and the plain of Carlisle is by most writers ranked with new 

 red sandstone. 



An Account of Rolled Stones found in the main Coal Seam of 

 Cochfield Fell Colliery. By H. T. M. Witham, F. G.S. 



Specimens of rolled stones, and a fragment of quartz, were exhibited 

 and Mr. Witham stated them to have been found in the main coal seam 

 of Cockfield-fell colliery, in a portion of which they are of frequent oc- 

 currence. This portion is comprised in about 3 acres on the north side 

 of the trap dyke, which does not seem to have influenced the position 

 of the stones, as these are found in many instances at a distance of 400 

 yards from it, and occasionally at greater distances. Similar specimens 

 have been also met with on the south of the dyke as far as the outcrop 

 of the coal. In the coal which is altered by the dyke for about 25 yards 

 on each side, only one solitary specimen has been found, though they 

 are abundant in the solid coal adjacent. A specimen has been also 

 found at St. Helen's Colliery, two miles to the north-east. 



On Sections of the Mountain Limestone Formation in Alston 3Ioor, 

 exhibiting t/ie general uniformity of the several beds. By T. Sop- 

 WITH, i^.G^.<S'. 



Mr. Sopwith stated that these sections form a portion of illustrations 

 of the stratification across the island from the German Ocean at Sun- 

 derland to the Irish Sea at Whitehaven, which could not be fully com- 

 pleted in time for the present Meeting, but are now in progress for a 

 subsequent meeting of the British Association. This series of sections 

 will comprise the coal district of the county of Durham, by Mr. Bud- 

 die; the lead mine district, by Mr. Sopwith; the Cumbrian group of 

 mountains, by Professor Sedgwick ; and the Whitehaven coal field, by 

 Mr. Williamson Peile. The sections exhibited showed the succession 

 and relative thickness of the several strata, and comprised comparative 

 sections of the strata in the manor of Alston Moor, and of the work- 

 ings of several mines. 



On the Position of the Bochs along the South Boundary of the Penine 

 Chain. By J. B. Jukes, F.G.S. 



In this communication the calcareous strata of Derbyshire, which 

 form the lower part of the whole Penine chain of mountains, are de- 

 scribed at length ; the superincumbent limestone shale and millstone 

 grit are traced ; and the coal formation of Derbyshire is noticed both as 

 to its mineral composition and relations to the new red sandstone series
