believed, might have been accumulated contemporaneously with 
Liassic beds elsewhere. Furthermore he has made the remark- 
able statement that the shaft of the Langan lead mine was 
sunk, first through beds of fine Conglomerate, afterwards 
through the Sutton stone, and then to a depth of 150 feet into 
an unstratified Conglomerate, the bottom of which was not 
reached. This latter was supposed by Mr Moors to be identical 
with beds observed by him under the Sutton stone in the coast 
section. Bearing this statement in mind, I made a most careful 
examination at Sutton, but could not perceive the least evidence 
of any deposit in the position indicated by him. What Mr 
Moore observed at cave No. 2 (see page 528 of his paper) was, 
I believe, nothing more than a part of the Sutton stone itself, 
which, as Mr Bristow observes, ‘becomes hard and blue near 
that place.’”’* 
What I believe has led to great misapprehension in working 
out the beds is that the Lias Conglomerate has been taken for 
the Sutton Conglomerate, an error which could readily be made 
from the peculiar position of the beds along the shore. 
In the Section D, thirty yards west of the caves, it will be 
seen how the Sutton stone falls over a dome of Carboniferous 
Limestone and dips underneath the sea. Now near the caves 
the beds are shown fairly in sequence, and, as Mr Tomes 
mentions of the beds forming the upper two-thirds of the 
Section, that their lower limit is clearly defined by the fucoid bed 
mentioned by Mr Bristow, and by the line of fragmentary chert 
noticed both by him and Mr Tawney, but that No 2, although 
3 very decidedly Conglomeratic, is unquestionably true Lias, and 
that it contains characteristic Lias fossils.

© The statement made by Mr Moore, and here alluded to by Mr Tomes, 
is certainly a very remarkable one, and the more so as one object of Mr 
_ Moore’s paper was to show that the Sutton stone was nothing more than 
ordinary Lias, altered by contact with Mountain Limestone. Yet here we 
have one hundred feet of Conglomerate interposed between it and that

contrary, fully preserved.
