BRISTOL NATURALISTS' SOCIETY 
EXCURSION MEETING. 
From the Bristol Daily Post of September 20th, 1865, 
The last excursion for the season took place on Friday 
last, the 15th iust., and was devoted to examining the 
quarries of the inferior oolite at Dundry. The members 
were conveyed in a break furnished by Mr. Butsoo, which 
called for them at various parts of the city, aud proceeded 
lhr<jugh Bedminsler, After passing Bedminster turnpike, 
the road ascends towards the lias quarries on the Down. On 
the way, the president, Mr. W. Sanders, F.R.S., pointed 
out the junction lieds of the new red saudstone with the 
lias, and Mr. W. W. Stoddart called attention to, and dis- 
tributed specimens of, an interesting bed of limestone which 
occurs here, and is remarkable for the abundance (>f a water 
^ plant called Naiadites petiolata, and little bi-valve Esiherise. 
The road then continues over lias strata through the villajj-e 
of Bishport, and at the foot of Dundry-bill the party left 
the carnnge in order to walk up the tields adjoining the 
road. Here Mr. Sanders explained that this field was com- 
posed of the upper third part of the lias, and that at the 
upper end were traces of the Marlstoue beds, which, with 
the upper lias sands, were very thin and difficult to be 
recognised. On entering the road again at a sharp bend, 
the lowest beds of the inferior oolite were shown, 
and after ascending a little farther, the roadside quarries, 
named, for this occasion, "Cross-roads quarry," were 
reached and well " worked." Many interesting and charac- 
teristic fossils were obtained, including several S{jecies of 
Ammonites and Belemnites, Rhynchouella spmosa, Nautilus 
Hneatus, N. truncatus, Pecten barbarus, Modiola 
Sowerbyi, Trigonia costata, two species of Opis, Astarte, 
Lima proboscidea, and last, though not of least importance, 
a portion of a claw of the crustacean Glyphaea rostrata. 
Having satistied their geological desires, the party pro- 
ceeded to the church, and stopped to admire the noble tower, 
and to notice the hue condition of its several parts— the 
buttresses, string-courses, wiudow-muHions, &c., after 
enduring the storms of four centuries. Near here was seen 
the quarry containing beds of splendid building stone, equal, 
if not superior, to the Bath freestone. Being unfossihftrous, 
however, it did not call for a long visit, and the party pro- 
ceeded to the escarpment'* on the western margin of the 
bill, and the so-called Yew-tree quarry. Here every 
hammer was soon at work, and many fossils collected, in- 
cluding, in at-tdition to abundance of Ammonites, Triyonias, 
' &c., Ciiona, Lima Eiheridgii, Modiola crassa, Mytilus. as 
well as some of those species which were found at the tirst 
quarry visited. The summit of the down was then reached, 
and the members loitered to indulge in the glorious pano- 
rama visible from this point, which, owing to the clearness 
ol the air. was more than usually extensive, reaching 
to the White Horse, near Westbury. Mr. Sanders
