scattered flint-nodules, and shows well-marked N.W. and S.E. joints. 
The Jower division, or Broadstairs Chalk, on the other hand, is less 
jointed, and has many continuous layers of flint. The beds form a 
very flat arch, as may be seen along the coast from Kingsgate to 
Pegwell, between which places the flinty Chalk rises up from below 
that with few flints, 
It is remarkable that in this neighbourhood the Thanet Beds are ~ 
conformable to the Chalk, the green-coated nodular flints at the 
bottom of the former resting on a peculiar bed of tabular flint at the 
top of the latter. 
3. ‘On the Chalk of Buckinghamshire, and on the Totternhoe 
Stone. By W. Whitaker, Esq., B.A., F.G.S., &c.—In carrying on 
the Geological Survey of Buckinghamshire, the Totternhoe Stone 
(with its underlying chalky marl), which had been sometimes thought 
to be the representative of the Upper Greensand, was traced south- 
westwards into a part where that formation was fairly developed, 
and was then found to overlie it. 
The divisions of the Chalk in Buckinghamshire are, in ascending 
order,— 
(1) Chalk-marl, with stony layers here and there, and at top. 
(2) The Totternhoe Stone, generally two layers of rather brownish 
sandy chalk, hard, with dark grains of small brown nodules. 
(8) Marly white chalk, without flints. 
(4) Hard-bedded white chalk without flints, forming generally a low 
ridge at the foot of the great escarpment. 
(5) The thick mass of white chalk without flints, or with a very few 
flints in the uppermost part, and at top. 
(6) The ‘Chalk-rock,’ already described in the Society’s Journal, a thin 
hard bed or beds, with green-coated nodules. 
(7) The Chalk with flint, the lowermost part only coming on near the 
top of the escarpment, the rest bed by bed over the table-land 
southwards, the angle of dip being rather more than the slope of 
the ground. 
4, ‘On the Chalk of the Isle of Wight.’ By W. Whitaker, Esq., 
B.A., F.G.S., &c.—The chief object of this paper was to show that 
here, as in Oxfordshire, &c., the division between the Chalk with 
flints and Chalk without flints is marked by a peculiar bed (‘ Chalk- 
rock’), hard, of a cream-colour, and with irregular-shaped green- 
coated nodules, which may be seen in many of the pits on the 
southern flank of the chalk-ridge, where, however, it is very thin. 
The author disagreed with the inference that the Chalk was eroded 
before the deposition of the Tertiary beds, which has been drawn 
from the irregular junction of the two in the cliff-sections, and 
thought that the irregularity had been caused rather by the forma- 
tion of ‘pipes’ after the deposition of the latter, although he did 
not deny that there was other evidence of denudation of the Chalk 
before the deposition of the Tertiaries upon it.
