contortions (notably one, a complete inversion) of the lower chalk 
and chalk marl beds were pointed out. It was mentioned that 
these ‘‘creeps,”’ as they are elsewhere named, might be explained 
by the differential movements and sliding of the chalk in this part 
over the underlying gault, a process due to the immense quantity 
of underground water present in the chalk at the depth exposed by 
the cutting. The district has a peculiar interest in relation to its 
water storage, since close to the village of Etching is the upper 
Nailbourne source of the lesser Stour, and in less than a mile, 
through a gap in the hills, Postling Church is reached, and, close 
by it, the Eastern arm of Great Stour commences, and pours in a 
permanent stream from the bottom of the chalk. The physiography 
of the district, from the hill above tunnel and cutting, was viewed 
and dwelt upon in relation to its denudation as shown by curving 
valley rounded hills with gaps and wide stretching views beyond. 
Blocks of ironstone from the Paddlesworth beds above the chalk 
were next examined and searched for fossil remains, and between 
Acryse and the Elham Mill a pit was entered which showed a 
section of the sands that cap the high ground. These sands, 
which have been correlated with those of the well-known Lenham 
pipes, were originally referred by Prestwich to the Crag; after- 
wards on stratigraphical and lithological grounds, Whitaker classed 
them with the Oldhaven beds, and they are mapped as such. In 
1886, however, on the paleontological evidence from the Lenham 
beds, Clement Reid placed them as probably homotaxeous with the 
base of the Coralline crag; if the westward extension of the crag 
should be confirmed the point will be one of great interest. 
XXIX.—Presence of Falcaria Riviri in Hast Kent.—By G. Dowxer, 
F.G.S. 
OcToBER 13, 1887. 
Specimens of the plant were exhibited. It was found growing 
in the parish of Preston, near Wingham. It is a rare visitor in 
the British Isles, and has only been noticed on one other occasion 
in Kent by the Rev. — Moore, near Birchington-on-Sea, of which a 
notice appears in the ‘‘ Journal of Botany” for August. It was 
conjectured by the Editor, Mr. Britten, that it had been introduced 
with some foreign seed of clover, as it appeared in corn fields. It 
is a curiously leaved umbelliferous plant, that would generally be 
noticed by any botanist as distinct from any of the numerous 
umbelliferse found in this country. Mr. Dowker found it in strong 
erowth, and in some quantity in a pea field in the month of 
August this year, and had previously observed it in the same field 
thirty years since, but had not noticed it in the interval, so this 
plant may at least seem pretty well established. It does not seem 
to perfect its seed, which may account for its not spreading.
