and seeds, for not a single stone was met with. This proved to he 
a very troublesome business, as only a small amount could be 
treated at once. In fact this mechanical part of the work has 
taken so long, that there have not yet been time to finish the 
determination of the plants. However, the general results can be 
given. 
Unlike most of the deposits near Cromer which I have examined 
for seeds, the Gorton beds seem to have been deposited as flood 
loam, and not as true lacustrine clays. Aquatic plants are 
comparatively scarce, the common species being such as we should 
find on an Alder (Jarr. The Alder itself is very abundantly 
represented by cones and seeds ; other trees are only recognised 
by driftwood. Cotton Grass and a species of Buttercu]) come next 
in abundance. Then follow the Hornweed, several Sedges, Pond- 
weeds, Bur-reed, and Atriplex. 
The seeds are very much compressed, more so than is usually the 
case near Cromer. But this, and the greater amount of decay they 
have undergone, I take to be the result of the longer exposure to the 
weather in pre-glacial times. A seed sinking at once to the bottom 
of a lake suffers less than one exposed for a time to alternate flood 
and drought. 
O 
The determination of the plants is not yet complete, and there 
will evidently be two or three unrecorded Sedges to add to the 
Flora of the Cromer Forest-bed. However, the species, as far as 
known, are as follows : — 
Banunculus sp. Abundant. 
Thalictrum flavum. Linn. One. 
Atriplex patula. Linn. One. 
Alnus glutinosa. Linn. Very abundant. 
Ceratophyllum demersum. Linn. Abundant. 
Sparganium ramosum. Curtis. Six. 
PoTAMOGETON LUCENS. Linu. Three. 
„ TRiCHOiDES. Cham. Abundant. 
Zannichellia palustris. Linn. Two. 
SoiRPUS PAUCiFLORUS. Lightf. Abundant. 
„ LACUSTRis. Linn. Ptare. 
Eriophorum angustifolium. Both. Abundant. 
Carex. Two or three species not yet determined.
