496 S. V. Wood—The Long Meadend Bed. 
than twenty yards in length, in the upper four or five feet of a fine 
white impalpable sand, so hard as to be cut into blocks, full of Limnea, 
Paludina, and other freshwater shells, and of the remains of the 
American river fish Lepidosteus, which was overlain by a layer of 
pinkish stone (with freshwater shells) from 12 to 18 inches thick, 
blocks of which we had to detach to get at the sand beneath. The 
part of the cliff thus worked by us was clean scarped (a talus 
occupying the part below, and giving us access to it), and just about 
midway between the beach and the cliff top. It was about three 
furlongs east of Meadend. By the dip of the beds this sand rose 
westwards and ran out beneath the unconformable gravel and near 
the cliff top at or immediately west of Meadend, cut off there by the 
denudation which preceded the deposit of that gravel; while east- 
wards it was overlain and succeeded by beds of purely freshwater 
clay, marl, and sand, which yielded principally Paludina and Unio 
(Solandri), and which by the easterly dip disappeared beneath the 
talus as the place of the “ Upper Marine” (or Middle Hleadon) was 
approached. This “ Upper Marine” in its turn was from the same 
dip succeeded eastwards by freshwater beds (Upper Headon), until 
by the fall of the cliff top to the beach level, near Milford, every- 
thing disappeared. 
I submit therefore that my father’s assignment of this bed, as — 
transitional from the Barton to the Lower Headon, is borne out to 
the full, both paleeontologically and stratigraphically, though, as the 
sands with lignite, now I believe regarded as Upper Bagshot, which 
principally constitute the cliff between Meadend and the rise of the 
Barton beds as we go west, were, so far as we could detect, otherwise 
unfossiliferous, these may (though I think not) be freshwater, and 
so interrupt that transition ; but the presence of the bed higher up 
in the cliff at the place where I and the others worked at it, as Mr. 
Keeping says he found it from digging to be, is quite inconsistent 
with its having ‘all the Lower Headon freshwater beds below it.” 
Nothing but an intervening denudation which had, previous to the 
deposition of the bed here, removed the succession of clays, sands, 
and marls, with Paludina and Unio Solandri, just described, would 
be reconcileable with the geological position Mr. Keeping thus 
remains of Hordwell were obtained, I desire to record that the whole of those which 
my father and I obtained (with the exception of a fragment of the jaw of Palgotherium 
with teeth, many plates of Trionyx, and some Crocodilian teeth, which were obtained 
from a layer of brown sand over the shelly seam in the Meadend bed itself,) were 
procured from the one place and horizon mentioned in the text, and comprised the 
remains of Alligator (Crocodile according to some paleontologists), Emys, Palgo- 
therium, Microcherus, and Spalacodon, figured in the London Geological Journal, as 
well as the cranium of a Rodent, still, I believe, unnamed, some small ophidian 
vertebre, and part of a bird’s bone, all of which have been these 35 years past in the 
British Museum. Mr. J. W. Flower obtained the larger of the two fragments of the 
jaw of Spalacodon figured, and a fragment of Paleotheriwm jaw with teeth, from a 
tew feet lower in the same hard sand nearer to Meadend. I sent to Professor Judd a 
sketch that I made in 1843, and had preserved, of the cliff, showing all the parties 
at work at it in that year, and the positions they occupied. From what part Mr. 
Keeping procured the remains collected by him for the Marchioness of Hastings I 
know not; but this was not until after the conclusion of our labours in 1846,
