546 A. CHAMPERNOWNE AND W. A. BE. USSHER ON THE 
micaceous and sectile. In the roads north from Canningtun to 
Cannington Park the surface-dip seems to be southward, with 
undulations. An exposure in an adjacent field showed red-brown 
shales with occasional greenish mottling, under red Triassic sand, 
near the northern margin of the patch. With the conditions 
under which these inliers present themselves there is such a con- 
stant chance of raddling from Trias, that the colours of these soft 
arenaceous mudstones cannot be considered of much value, and 
they may be of almost any age, from the Culm-measures down- 
wards. 
Their relations with the Cannington-Park limestones are ob- 
secured by Triassic sands occupying the valley between the inliers. 
Large E. and W. faults prevail in the Bridgewater area, notably 
one on the south of Fiddington, with downthrow on the south‘ 
and this, if continuous, would make the Cannington inlier above 
the limestone; but the frequency of these Post-Triassic dis- 
turbances along E. and W. lines would justify a belief in pre- 
cedent lines of fracture in similar directions concealed by the 
Trias ; so that in the absence of any evidence of relations between 
the Cannington and Cannington-Park inlers, it seems not un- 
reasonable to regard their junction as a pre-Triassic fault, probably 
of great magnitude. 
The limestone is well bedded, and intersected by numerous 
irregular joints. As far as evidence goes, the dips in the quarry by 
the road on the south side of the park would make the strike of the 
limestone at right angles to the trend of the adjacent inlier, 2. ¢. the 
reverse of what would happen were their relations normal. On 
the N.W. side of the quarry the dips range from W. 42° 8. at 
20° to 8. 25° W. at 25°; and on the N.E. face the beds dip E. 30° S. 
at 40°. A similar change of dip is observable on the south side of 
the quarry. In the 8.W. corner, near the entrance, the beds dip W. 
at 70°, and W. 15° S. at 55°, whilst on the S.H. a dip E. 20° N. at 
38° is observable, also 8. 42° H. at 20°. The beds therefore form 
an anticline, the axis of which trends in a N. and S. direction. In 
one part of the southern face two fissures filled with Triassic sand 
were observed. 
he limestone is of light grey and dove-coloured tints, intersected 
by pinkish veins and strings of calcite. Much is of oolitic struc- 
ture, identical with that of the Mountain Limestone at Clifton, and 
also on Broadfield Down, near Yatton. We have never seen oolitic 
structure in any of the South-Devon limestones. Traces of crinoidal 
stems and corals we observed on the spot, but nothing that could be 
identified. 
In the Taunton Museum we were shown the following specimens: 
—(1) Productus, of small size, apparently P. cora, as it has the 
wrinkled ears and delicate rounded strive of that species, labelled 
“J.H. Payne, Cannington Park Limestone, October 24th, 1851; ” 
(2) Lithostrotion, two fine polished specimens of a ceespitose form, 
apparently Z. Martini; (3) Lithostrotion basaliiforme; the Corals 
from the Baker Collection. (With regard to No. 3, the identification 
is open to question.)
