advantage of such an exposure as the railway now presents, 
but the occurrence of a quarry of Gryphite Grit about twenty 
feet above what is marked by them as Midford Sands, indicates 
something unusual. 
These beds of sand in this cutting are not lithologically 
similar to the sands at Harford. In fact, they are not of that 
fine yellow colour, nor very micaceous, but are rather brown- 
ish debris, mixed with shelly detritus in places, and with a 
certain admixture of mica. From this, however, we must 
except bed No. 2, especially the upper part, which has a 
much more sandy appearance, and is almost free from debris. 
Bed 4 has much more resemblance to the marly debris mixed 
with a little mica, which I have classed at the top of the Upper 
Freestone series (sections II., 14), but is coarser and less sticky. 
Before finally leaving these beds of sand I quote the follow- 
ing remarks of Dr Hull,* which shews that a change in the 
nature of these sands occurs elsewhere, “at Cleeve Cloud 
the Ragstone contains a bed of siliceous sand at or near the 
base, which may also be observed on Broadway Hill, near the 
Tower, in a quarry. This bed of sand appears in some localities 
to give place to clay, sha e, etc.” 
We thus see that we have this bed of sand extending from 
Andoversford eastwards nearly to Bourton-on-the-Water, and 
northwards past Cleeve Hill to Broadway Hill, and that it seems 
to form a very definite horizon, which Dr Wright has at Cleeve 
Hill considered to be in the zone of Am. Humphriesianus, in 
which he also includes the Upper Freestone. It seems to me, 
however, that this sand is an extremely good dividing line 
‘between the end of Lycett’s Fimbria Stage and the beds which 
we are now going to consider, viz., the Ragstones and Lime- 
‘stones exhibited near Bourton, which lie between the sands 
below and the beds with Gryphea sublolata above. 
In the Stroud area we find that the beds containing Gryphea 
‘sublolata rest directly upon the Upper Freestone. We also find 
that the top of the Upper Freestone is considerably bored by
