veyance to a distance, should until lately have been lost 
sight of, and that, for a long period the best beds in these 
quarries should not have been worked. Formerly their value 
must have been appreciated, as is evidenced by the shafts 
and excavations everywhere apparent. No better illustra- 
tion of the durability of the stone they yield can be pre- 
sented than in the churches of Dundry and Redcliffe, 
Bristol, which were built with stone from this locality. The 
beds of oolite at Dundry are about fifty feet in thickness, 
and in descending order would show, 1st—raggy beds which 
are removed to obtain the best stone for building. 2nd,— 
beds of freestone for which the quarries are now worked 
12 feet in thickness. These are not rich in organic remains. 
3rd,—Rubbly beds of stone with intervening patches of 
sand and sandy clay overlying No. 4, the lowest or am- 
monite bed, for which this locality has so long been cele- 
brated. It is from this bed all the organic remains have 
hitherto been obtained. Knowing that it had yielded nearly 
two hundred speeifie forms, I looked forward to my visit to 
Dundry with pleasurable antieipation. It happened how- 
ever, that the ammonite bed had been of late but little 
worked, and as it underlies those of most value it is not 
so likely to be reached for the future. During the day I 
obtained but two or three species of Terebratula and Rhyn- 
conella, a Lima, and.a few corals, from a locality un- 
doubtedly rich, so that I did not realize the expectations 
with which I set out upon my excursion. 
On returning from Dundry to Bristol, on the north side 
of the hill, above the village of Bishport, are several small 
quarries by the roadside, the upper beds of which are com- 
posed of the rubbly stone mentioned above in section 3. 
The one nearest Bishport shows signs of much distur- 
bance and has a considerable dip to the north. In this
