INFERIOR OOLITE SERIES : HAM HILL. 73 
resting on about 12 feet of false-bedded shell-limestones. It was here 
that I obtained Rhynchonella cynocephala somewhat abundantly.* 
Mr. Rhodes subsequently obtained specimens of Ammonites, 
Belemnites, Avicula, Lima, Ostrea, Pecten, and Tercbratula, in a 
more or less fragmentary condition. Sands with thick bands and 
nodular masses of sandy limestone were seen in the lane-cutting 
below. 
On the south side of the road another quarry showed sands 
with bands of shelly limestone. The building-stone evidently 
becomes poorer in this direction, the sand containing shelly 
layers only at irregular interval:?. 
West of Stoford the Inferior Oolite is very thin ; and this 
perhaps accounts for the fact that the Fuller's Earth is shown on 
the Geological Survey Map to rest directly on the Sand, south- 
west of Barwick (Berwick). A quarry north-east of North 
Coker, near East Coker, showed about 3 feet of thin flaggy lime- 
stone, there dug for road-metal. The two outliers (marked on 
the Map) are not in reality separated, and they appear to be 
overlaid by clay (Fuller's Earth) to the south-east. Here how- 
ever the low ground is in part Alluvial and no sections are to be 
seen. The fossils from the Inferior Oolite of East Coker, indicate 
the zone of Ammonites Murchisonce.^ Westwards, the Forest 
Marble and Fuller's Earth are probably faulted against the 
Midford Sand. No doubt a re-examination of the ground 
will show that the abnormal relations represented on the Survey 
Map, between the Fuller's Earth and Inferior Oolite in other places, 
near the IChinnocks and Merriot, are due to faults, although 
perhaps owing to the attenuation of the Inferior Oolite limestone, 
this rock has not in all cases been observed where present. 
The thinness of the Inferior Oolite is well shown in a quarry 
south-west of Yeovil Junction, and north of Stoford, where the 
beds from the base of the Fuller's Earth down to the Sand, are 
reduced to about 7 feet. The beds shown were as follows:
