PALMOZOIC DISTRICTS OF WEST SOMERSET. 5a7 
split off by numerous irregular joints, sometimes glazed with heema- 
tite, and approximating to a slaty structure in places; bands of 
chocolate-coloured clayey shale are occasionally interstratified. The 
beds dip 8S. at 5°.

From here to Dunster grits are evidenced by surface-stones, but 
no sections were observed. If the Timberscombe grits belong to the 
Foreland group (as similar beds are exposed near Porlock), a fault 
between Bickham and Withycombe must bring the Hangman and 
Foreland groups into juxtaposition, cutting out the intermediate 
Lynton beds; and this we hope to prove by the next traverse. 
From Dunster to THE Foretanp. 
As in the previous traverse no beds equivalent to the even grey 
grits and fossiliferous schists of Lynton were crossed, Mr. Etheridge 
haying clearly shown the mantling of the Hfracombe slates and 
associated limestones round the east end of the Croydon-Hill anti- 
clinal, formed of Hangman grits, and as in our traverse from Wil- 
liton to Cannington, hereafter to be described, we were unable to 
trace the Lynton division, it was of the utmost importance to account 
for its disappearance, and for the great breadth of grits occupying 
the area from Cutcombe, on the south, to North Hill, near Mine- 
head, on the north. 
The south side of Grabbist Hill consists of reddish-brown grits, 
in which no reliable dips were obtainable till we reached Slatcombe, 
near Wooton Courtney, where the beds dip N. 15° E. at from 5° to 20°. 
On the western flanks of Grabbist Hill, near Lower Knoll, hard 
reddish-brown siliceous grits with numerous irregular joints, and
