a good deal had been since taken away. It is on the slope of a 
small hill rising about eighty feet above the flat ground of Lias, 
and rests upon the Mountain Limestone, but it was clear to my 
mind that it was merely a large mass of drift; indeed it has 
that appearance in Mr Moore’s figure, page 521, Quart. Journ., 
Dec., 1867. Thence to St. Mary’s Hill Common. It was a long 
time before we could find Termydd, which lies a little west of 
the Common, to which we were at last directed by the Clergy- 
man, two of whose parishioners we had before asked, but they 
were both so deaf that we could not make them understand. 
It is referred to by Mr Bristow, page 204, as containing Sutton 
stone, and as beds intermediate between the ordinary Lias and 
Carboniferous Limestone. He gives the dip as 25° in a direc- 
tion west of south. I confess I could not satisfy myself as to 
_ the position of these beds. 
On to Paulline, and from there walked to Cwrt, near which 
are the old lead mines, and in a wood near the Rhetic shales 
come up to the surface. On the way back to Bridgend, at 
Tythegstone, there is a quarry in the grounds of the Rev. G. 
Kyieut, which appears to be Dolomitic Conglomerate. 
About a mile and a half from Bridgend is Angleton, where 
there is a quarry, out of which the new Lunatic Asylum, close 
to, was built. There are cappings of Millstone Grit drift, and 
underneath are some apparently Rhetic shales: then comes 
the building stone, which Mr Tawyey. regarded as the base of 
the Keuper, but which Bristow says represents the upper part 
of the Rhetic, and explains (in p. 205 of his paper) that “the 
replacement by Sandstones of the ordinary Calcareous and 
_ muddy sediments of which the Rhetic series is generally com- 
posed indicates here a coast-line and shallow water,” but without 
expressing a definite opinion, I am inclined to accept Mr 
- Tawney’s view. 
Crossed the Ogmore by the bridge, and on returning to 
Bridgend, passing along the bank of the river, in the bed the 
_ Rheetics are again seen, and within half a mile of Bridgend is 
the-Quarella quarry, the top covered with a thick bed of drift, 
underneath which are Rhetic shales of about three feet,
