quartz, &c. ; it appears to have been formed of 
the detritus of tlie rock on which it reposes, and 
corresponds to the finer varieties of the Tilgate 
conglomerate, hereafter to be noticed. The blue 
grit contains paludincB in abundance, and the Cyclas 
parva. In the sands and soft sandstone, vegetable 
remains are most abundant, but they are too im- 
perfect to admit of accurate determination ; they 
belong 'to the genera Sphcenopteris, Lonchopteris, 
and, perhaps, locopodites and calamites. Some 
bones of the large saurians, which have rendered 
the strata of Tilgate forest so celebrated, have been 
discovered in the sand near Bexhill ; and a portion 
of a femur and leg-bone, os iympani, and vertebra 
of the Iguanodon, were shown to me by Dr. John- 
ston, on my visit to Hastings in 1832. 
Proceeding eastward, we find, to the west of 
Hastings, the first indication of the Tilgate beds, 
in the form of large masses of grey calciferous 
sandstone, which lie scattered along the sea-shore. 
The blocks of this substance, that have been long 
exposed to the action of the waves, are almost 
wliite, and hence the name of “ TPHiite Jdock” given 
to a large portion of the cliff which has slipped 
from its original situation, and is now exposed on 
the beach, near one of the stations of the blockade 
service. The largest mass of the strata, in this place, 
is about 30 feet high, and consists of — 
1. Loam and vegetable mould ; the summit of 
tlie cliff* 
2. Sand, and friable sandstone, of a fawn
