60 Origin of the British Flora. 
Some clays overlying the Eocene lignite deposits have 
yielded a few Arctic plants. It is not clear whether these 
should be classed as Early or Late Glacial. They yield:— 
Arctostaphylos Uva-ursi. Salix cinerea. 
Betula alba. Pinus. 
———- nana. 
BRIDLINGTON, YORKSHIRE. 
(Nathorst, ‘Ueber neue Funde von fossilen Glacial- 
pflanzen, Exgler’s Bot. Jahrb., 1881, p. 431.) 
A hollow in the boulder-clay, filled with peaty marl, 
is here classed as Late Glacial from its stratigraphical 
position and the occurrence in it of Betula nana. 
BROUGHTON, EDINBURGH. 
From a peaty deposit at this spot Mr. James Bennie 
has recently obtained a few plants, probably of the same 
date as those from the Neolithic deposits at Hailes and 
Redhall. There is nothing characteristic in the list:— 
Ranunculus aquatilis. Polygonum aviculare. 
— Flammula. ———-- Persicaria. 
— Lingua. Rumex. 
repens. Potamogeton. 
Stellaria media. Scirpus setaceus. 
Montia fontana. Eriophorum. 
Carduus. Carex. 
Atriplex (?). 
CAERWYS, FLINTSHIRE.

Tufa in Flintshire, Geol Mag., Vol. IIL, p. 253. 1866;

An extensive deposit of calcareous tufa at this place is 
full of leaves; but the date cannot be fixed, as the tufa
