Mr. Baily and Dr. Martyn found HoloptyoliiuR scales. A 

 short search on three or four occasions lias only rewarded 

 me with one small fragment. It was at this point, too, that 

 the section recorded by tlio Naturalists' Society was raado. 

 The beds dip gently at an angle of somewhat loss than 20° 

 S.S.B. 



Prom this point wo may tnJco lilio road whi(^h ascends 

 West Hill. In doing so wo rise on to the more northerly of 

 the parallel crests spoken of by Buckland and Conybcare. 

 From this point the crest may bo followed wifclumt serious 

 break to Clevcdon. Between it and the Old lied Siindstono 

 of Wood Hill, however, which lies in the same lino, there is 

 low-lying ground, occupied by Triassic beds. "Following the 

 road to the corner whore O.B.S. 15° S.E. is recorded on the 

 map, wo turn to tho left, and, proceeding eastwards, descend 

 on to the Lower Ijiraestono Shales, which are, however, only 

 vo7-y imperfectly shown at one or two points by tho roadside, 

 at one of which, however, the Bryozoa bed is exposed. 



On reaching tho place where the road forks, and taking 

 the more easterly (left hand) branch, wo descend into a 

 lane, near the top of which beds, proved to be Lower Limo- 

 ■ stone Shales by the occurrence of the Bryozoa bed, are seen 

 m a nearly vertical position, one bed giving an E. dip of 

 JT)", others perpendicular, while a marly bod shows con- 

 tortions. A little farther down this lane beds of unmistak- 

 able Old Red Sandstone put in an appearance, while still 

 farther down, near a cottage, chai-acteristic conglomeratic 

 beds, with pebbles of opaque white quartz, are seen, the beds 

 here dipping steeply about 75° N.W. A little lower down 

 they are overlain and hidden from view by Triassic beds. 



Retmming to the place where the road forks, and taking 

 the other (right-hand or southerly) branch, we descend 

 another lane, in which near the top are obscurely seen
