Deposits containing Fossil Plants. 83 
upper freshwater bed is a thin seam of lacustrine clay, full 
of seeds of aquatic and marsh plants. The flora of this 
deposit is so uniform at most of the localities, that it is 
needless to repeat the list. 
Above the Forest-bed lies an Early Glacial flood-loam 
or loess-like deposit containing bones of a Spermophilus 
and leaves and seeds of Arctic plants, the species being :— 
Hippuris vulgaris. Salix polaris. 
Still higher, and cutting through the boulder clay, is 
seen an old river channel, subsequently silted-up with 
Alluvial mud containing remains of the water-tortoise 
(Emys lutaria), shells of Hydrobia marginata, and plants, 
the species observed being Muphar luteum, Ceratophyllum 
demersum, and Salix. This deposit is probably equivalent 
to beds D and E at Hoxne, and is here provisionally 
classed as Interglacial.

An Alluvial deposit of uncertain age yields the 
following plants, sent to me by Mr. H. N. Dixon:— 
Nuphar luteum. Polygonum. 
Stellaria media. Mercurialis perennis. 
Prunus spinosa. Alnus. 
Padus. Corylus Avellana. 
Sambucus nigra. Quercus Robur.

Two distinct plant-bearing deposits are here repre- 
sented. The older belongs to the Preglacial Cromer 
Forest-bed, and contains cones of Picea excelsa and fruits 
of Tvrapa natans. The newer is Early Glacial, contains
