^ a. Fine ash-coloured sand,, regularlij stratified, very like the sands 
with clay beneath the ironstone of Furze Hill 4 feet. 
$ , h. Dark-brown and ferruginous sand, with a mixture of small pebbles, 
Bryozoa, Terebi-atulte, etc., regularly stratified 4 feet. 
, c. Ditto, ditto, with two or more bauds of hard calcareous coucretions, 
each about eight inches in thickness 5 feet. 
This last was the lowest stratum exposed, but, from the appearance 
of the soil, the pebbly sands extended somewhat lower. 
In the looser materials composing the strata h, c, we immediately 
recognized the upper portion ot the Red-gravel of East pit, contain- 
ing here, as there, Rhijnclionella nuciformis in abundance, B. latiS' 
sima, B. depressa, Terebratella Menardi, Terehratula Tornacensis, T. 
depressa, more rarely ; and, in addition, a few specimens of Terebra- 
tella ohJonga, Sow. 
In the intermediate stone-beds, c, T. obloncja was not uncommon, 
associated more rarely with i?. depressa, T. Menardi, T. depressa, 
and T. Bohertoni, D'Arch. The stone also contained Avicula Rau- 
liniana, D'Orb., Pecten Rauliniana, D'Orb., P. orbicularis, Exogyra 
conica, var., and E. lialiotoidea, — sliells which occur in the " Bargate 
Stone" and "Pebble-beds" of Godalming. In fact, except for the 
greater abundance of organic remains, this section agrees precisely 
with a section exposed in a quarry of the Lower Greensand near 
St. Katherine's Chapel, Guildford, where "pebble-beds" alternate, 
for a thickness of twenty feet or more, with layers of the " Bargate 
stone." 
I was greatly pleased at finding Terebratella oblonga here in 
such comparative abundance, associated with T. Menardi, etc., as I 
had only met with a single specimen in the Sponge-gravel. Yet, 
what seemed to me to be of greater interest in tliis Badbury Hill 
section was the upward passage of the dark-coloured pebbly strata h 
(Red-gravel) into a, — thus, as it were, limiting the position of the 
Sponge-gravels within a definite vertical range ; the fine sandy strata, 
a, underlying the ferruginous sands with chert and ironstone as well 
here as at Furze Hill and Farringdon Clump. 
Our time being limited, we now returned towards Farringdon, re- 
visiting the pits at Little Coxwell, and again examining the junction 
of the Sponge and Red-gravels in East pit. 
From what I have now seen of the several sections in the neigh- 
bourhood, I can form but one opinion as to the position of the Sponge- 
gravels with relation to the surrounding deposits, viz. that the true 
"Sponge-gravel" of the AYindmill-pit is unquestionably fhe oldest 
of the Cretaceous deposits near Farringdon, the strata exposed in the 
sections' at East Pit and Badbury Hill (see sections 2, '6), forming, 
as nearly as possible, a continuous series ; while at the same time 
there is no reason to doubt that the fossiliferous concretions capping 
Furze Hill are identical with the ironstone concretions which occur 
near the top of Badbury Hill, intermingled, here and there, with the 
cherty fragments. In ofi"ering so strong an opinion on this subject, 
I am, however, willing to confess, that had I not seen the actual junc-
