are also found. The Oldhaven Beds yield the same species, and 
some others, as Pectunculus plumsteadensis, and the gasteropods 
Melanopsis, Neritina, and Buccinum.” 
9th. July 1st.—To the outlier of the Blackheath pebble-beds at 
Worms Heath. In the large pit on the south-western side of 
the heath these beds are of a somewhat exceptional character, 
being largely of a bright crimson, from the occurrence of iron- 
oxide, and often cemented into huge blocks by the iron-oxide. 
There are signs too of their having been partly let down into a 
pipe or hollow in the chalk beneath. The rather rare but by no 
means beautiful mineral, allophane (a hydro-silicate of alumina) 
was found here by the President a short time before, and plenty 
of small pieces were now got in sandy and loamy beds beneath 
the pebbles. This is the only recorded locality in the county. 
Above the pebble-beds is some irregular gravel, chiefly composed 
of flints, but little worn, and in places between this and the 
pebble-beds is a little fine sand, with some green-coated flints 
and pieces of allophane. The green-coated flints presumably 
come from the base of the Thanet Sand, and probably the sand 
is a mass of that formation, which has slipped over, or has been 
carried over the pebble-beds from some former high land; its 
proper place being, of course, beneath thenr, and next above the 
chalk. i 
10th. July 15th.— To Coulsdon, Chaldon, White Hill, and 
Caterham. Conducted by Mr. A. J. Hogg. 
«“ An excursion was conducted by Mr. A. J. Hogg from 
Coulsdon to Caterham. About twenty-five members attended, 
and, leaving Coulsdon Station, ascended to the broad elevated 
chalk ridge of Farthing Down, some 480 ft. above O.D. At 
nearly the highest point the remains of several British tumuli 
were observed, and the turf was gay with patches of Polygala, 
Spirea, Campanula, &c. After some pleasant loitering, the 
party proceeded through a shady lane, a mile or so in length, to 
the ancient church at Chaldon. Here a prolonged stay was 
made for the purpose of inspecting and photographing the 
curious painting of the ‘Ladder of Salvation,’ supposed to date 
from the twelfth century, which covers one wall of the little 
puilding. The picture is a graphic representation of the infernal 
regions as they existed in the imagination of the enlightened 
artist. 
‘«« Leaving the church, which stands at 550 ft. above sea-level, 
an uphill road led to Hill-top Farm (600 ft.), and, turning in 
here, the Pilgrim’s Way was soon entered, and the wayfarers 
were charmed with the great variety and beauty of the wild 
flowers, as well as by the diversified and extensive views of the
