beds are Conglomeratic, and in appearance much resemble the 
Sutton stone. They are Lias; and I believe they have been - 
mistaken for the Sutton stone, and many of the supposed 
Sutton stone fossils were probably taken out of these beds. I 
think it likely it was from these beds that Mr Cuartzes Moore 
found Am. angulatus, a form he well knew, and which he was 
not likely to mistake; but he may have made an error in the 
formation, which here is certainly deceptive. 
Itis of course of paramount importance in the interpretation 
of this interesting coast section that the exact stratigraphical 
position of the Sutton stone, so peculiar lithologically, as well 
as paleeontologically, should be made clear; and in addition to 
what has already been said in favour of its similarity in so many 
respects to the upper Rhetic beds, we may remark that we 
believe there is very direct stratigraphical evidence of its lying 
below all those beds exposed in the section. If we take a position 
when the tide is out, immediately in front of the cliff, and far 
enough away to take all in from Sutton to the road leading 
from Southerndown to the shore, we shall see that all the beds 
east of the caves, from top to bottom, dip eastward and pass 
out of sight. West of the caves the dip is the same in all the 
upper beds, but less distinct in the lower or Sutton Stone beds; 
yet it may be traced in the lower ones too, and a little reflection 
will show that one of three alternatives must be accepted. 
Hither the Sutton stone is conformable with the overlying Lias, 
and is inclined at the same angle with it,—or it must thin out 
very rapidly to the east and present a wedge-shaped mass,—or, 
if it does not dip eastward, it must be wholly uncomformable 
with the overlying Lias. That the Sutton stone, as Mr Moorg 
supposed, passes horizontally into the Conglomerate, and thence 
into the true Lias, is only possible when the beds of all are 
horizontal also; and we know that they are not. And as there 
is not the slightest evidence of the thinning out of the Sutton 
stone, or of its being uncomformable with the beds above, we 
can only conclude that it occupies a perfectly normal position 
below the Lias, and with it dips to the east, and is speedily 
lost sight of.
