HO MR. W. AVICKHAM KING ON THE PERMIAN [Feb. 1 899, 



For the remaining 2^ miles to the north-west the band becomes 

 less calcareous, and is devoid of pebbles. 



In Band A" marls predominate to the south and sandstones to 

 the north. 



Band B\ for the first mile to the south, is a calcareous sandstone 

 with a few small pebbles. For about 2 miles in the centre of the 

 district it is often a massive conglomerate 20 to 25 feet thick 

 (Bowhills Barn and Astley Bank), containing many pebbles 3 inches 

 long and some measuring 5 inches. For the last mile to the 

 northward it is a calcareous sandstone, without pebbles. 



Band B^ consists chiefly of sandy marls at the southern end 

 of the district, and of sandstones for 3 miles at the northern end. It 

 increases in thickness in a northerly direction. 



Band C^ — At and south of Eomsley, and at Astley Bank, only 

 the basal calcareous sandstone is left. At Bowhills Farm and at, and 

 ^ mile north-west of, Coton Hall the band is a massive conglomerate, 

 20 to 30 feet thick. At Bowhills Farm some of the pebbles are 

 8 J inches long, many 4 to 5 inches, and some are nearly subangular. 

 At Coton Hall the material is finer, but I found one pebble 8 inches 

 in length. For the remaining | mile to the north the band is a sand- 

 stone, and is less calcareous than at the southern extremity. 



Band C^ consists of marls. 



The trappoid breccia D^ is left only near Eomsley and Coton 

 Hall. It contains fragments usually less than 6 inches long. 



The Bowhills Middle Permian is less variable than in the Enville 

 district, but the conglomerates are coarser and more prevalent. The 

 peculiarities of this district are as follows : — 



(i) The amount of calcareous matrix decreases in a northerly 



direction, 

 (ii) Bands A" & B^ are chiefly marls at the southern end, and 



sandstones at the northern, 

 (iii) The materials composing A^ decrease in coarseness from 

 south to north, while those of B^ & C^ are coarsest in the 

 centre and finest at their northern extremities, 

 (iv) The materials are coarser in the higher calcareous zones. 



lb. Warshill and Castle Hill. (PI. XI.) 



On the side of the Trimpley anticlinal opposite to that on which 

 the Bowhills district is situate, and at distances varying from over 

 3 miles south-east and 2 miles east from the southern extremity of 

 the Bowhills district, there are narrow strips of Lower, Middle, 

 and Upper Permian beds at "Warshill, and of Upper Permian at 

 Castle Hill. 



The Warshill area is small (about 1 mile long and ^ mile wide), 

 faulted against Coal Measures, and locally overlain by Lower Bunter 

 beds. The lowest Permian rocks visible are red marls, too thick to 

 belong to the Middle Permian. These are followed by a calcareous 

 Middle Permian band, about 40 to 50 feet thick : it is chiefly a
